The following standards shall apply to each provision in Attachment 3. Failure to
specifically reference this standard, or individual subsections 1.1 .3 below, shall not
be construed to mean this standard does not apply.
Pursuant to the Act, U S WEST shall provide nondiscriminatory access to the network
elements specified in this Attachment 3 at any technically feasible point that is equal in
quality to the access which U S WEST provides to itself, its customers or other CLECs and
that is on rates, terms and conditions that are just, reasonable and nondiscriminatory.
For purposes of this Attachment 3, "rates, terms and conditions that are just, reasonable
and nondiscriminatory" shall mean that (i) such terms and conditions are equal in quality to
the terms and conditions that U S WEST provides to itself, or, (ii) where it is technically
infeasible to provide such terms and conditions to AT&T, such terms and conditions are
offered equally to all requesting carriers
US WEST shall not offer to AT&T provisioning of or access to unbundled Network
Elements that is not equal in quality to what U S WEST provides itself. For purposes of this
Attachment 3, "equal in quality" shall mean, among other things , equal to the timeliness,
responsiveness, accuracy and integrity of the provisioning of or access to the Network
Element U S WEST provides itself.

Digital Cross-Connect System
Definition
Digital Cross-Connect System ("DCS'? is function which provides automated
cross connection of Digital Signal level 0 (DS-O) or higher transmission bit rate
digital channels within physical interface facilities. Types of DCSs include, but
are not limited to, DCS 1/0s, DCS 3/1s, and DCS 3/3s, where the nomenclature
1/0 denotes interfaces typically at the DS-1 rate or greater with cross-
connection typically at the DS-O rate. This same nomenclature, at the
appropriate rate substitution, extends to the other types of DCSs specifically
cited as 3/1 and 3/3. Types of DCSs that cross-connect Synchronous
Transport Signal level (STS-1) or other Synchronous Optical Network
(SONET) signals (e., STS-3) are also DCSs, although not denoted by this
same type of nomenclature. DCS may provide the functionality of more than
one of the aforementioned DCS types (e.DCS 3/3/1 which combines
functionality of DCS 3/3 and DCS 3/1). For such DCSs, the requirements will
be, at least, the aggregation of requirements on the "component" DCSs.
In locations where automated cross connection capability does not exist
Digital Signal Cross-Connect ("DSX'? or light guide cross-connect patch panels
and D4 channel banks or other DS-O and above multiplexing equipment used to
provide the function of manual cross connection will be made available.
Interconnection between DSX or light guide cross-connect, to switch
another cross-connect, or other service platform device, is included as part of
DCS.

17.4 Line Information Database (LIDB)
This Section 17.4 defines and sets forth additional requirements for the Line Information
Database.
17.4.Definition:
The Line Information Database ("L/DB'? is transaction-oriented database
accessible through Common Channel Signaling ("CCS'? networks. It contains
records associated with subscriber Line Numbers and Special Billing Numbers (in
accordance with the requirements in the technical reference in Section 17.5).
L/DB accepts queries from other Network Elements, or AT&T's network, and
provides appropriate responses. The query originator need not be the owner of
L/DB data. L/DB queries include functions, such as screening billed numbers, that
provide the ability to accept Collect or Third Number Billing calls and validation of
Telephone Line Number based non-proprietary calling cards. The interface for the
L/DB functionality is the interface between the US WEST CCS network and other

18.Protection, Restoration , and Disc;ister Recovery
18.Scope:
This Section refers specifically to requirements on the use of redundant network
equipment and facilities for protection, restoration, and disaster recovery.
18.Synchronization
18.4. 1 Definition:
Synchronization is the function which keeps all digital equipment in
communications network operating at the same average frequency. With respect to
digital transmission, information is coded into discrete pulses. When these pulses
are transmitted through digital communications network, all synchronous Network
Elements are traceable to stable and accurate timing source. Network
synchronization is accomplished by timing all synchronous Network Elements in the
network to stratum traceable source so that transmission from these network
points have the same average line rate.
18.4.Technical Requirements
The following requirements are applicable to the case where U WEST provides
synchronization to equipment that T& T owns and operates within US WEST
location. In addition, these requirements apply to synchronous equipment that is
owned by U WEST and is used to provide Network Element to T& T.
18.4.2. 1 The synchronization of clocks within digital networks is divided into two parts:
intra-building and inter-building. Within building, single clock is
designated as the Building Integrated Timing Supply ("BITS'?, which
provides all of the DS-1 and DS-O synchronization references required by
other clocks in such building. This is referred to as intra-building
synchronization. The BITS receives synchronization references from
remotely located BITS such as a primary reference source.
Synchronization of BITS between buildings is referred to as inter-building
synchronization.
18.4.2.2 To implement network synchronization plan, clocks within digital networks are
divided into four stratum levels. All clocks in strata , 3, and are
synchronized to stratum clock, that is, they are traceable to stratum
clock. traceable reference is reference that can be traced back through
some number of clocks to stratum source. Clocks in different strata are
distinguished by their free running accuracy or by their stability during
trouble conditions such as the loss of all synchronization references.
18.4.Intra-Building
Within building, there may be different kinds of equipment that require
synchronization at the DS-1 and DS-O rates. Synchronization at the DS-
rate is accomplished by the frequency synchronizing presence of buffer
USWC/AT&T Interconnection Agreement - Idaho 07/27/98
Attachment 3
Page 51
stores at various DS-1 transmission interfaces. Synchronization at the DS-
0 rate is accomplished by using composite clock signal that phase
synchronizes the clocks. Equipment requiring DS-synchronization
frequently does not have adequate buffer storage to accommodate the
phase variations among different equipment. Control of phase variations to
an acceptable level is accomplished by externally timing all interconnecting
DS-O circuits to single clock source and by limiting the interconnection of
DS-O equipment to less than 1 500 cable feet. Therefore, BITS shall
provide DS-1 and composite clock signals when the appropriate composite
signal is 64-kHz 5/Eih duty cycle, return to zero with bipolar violation
every eighth pulse (B8RZ).
18.4.Inter-Building
WEST shall provide inter-building synchronization at the DS-1 rate,
and the BITS shall accept the primary and/or secondary synchronization
links from BITS in other buildings where necessary. From hierarchical
considerations, the BITS shall be the highest stratum clock within the
building and U WEST shall provide operations capabilities. When
available, such capability includes, but is not limited to, synchronization
reference provisioning; synchronization reference status inquiries; timing
mode status inquiries; and alarm conditions.
18.4.Synchronization Distribution Requirements
18.4.Central office BITS shall contain redundant clocks meeting or exceeding the
requirements for stratum clock as specified in ANSI T1.101-1994 and
ANSI TI.105.09 and Bellcore GR-NWT-001244 Clocks for the
Synchronized Network: Common Genetic Criteria.
18.4. 3.Central office BITS shall be powered by primary and backup power sources.
18.4.31f both reference inputs to the BITS are interrupted or in degraded mode
(meaning off frequency greater than twice the minimum accuracy of the
BITS, loss of frame, excessive bit errors, or in Alarm Indication Signal), then
the stratum clock in the BITS shall provide the necessary bridge in timing to
allow the network to operate without frame repetition or deletion (slip free)
with better performance than specified in these technical references
specified in 18.4.
18.4.3.4DS-1s multiplexed into SONET synchronous payload envelope within an
STS-n (where "" is defined in ANSI T1.105-1995) signal shall not be used
as reference facilities for network synchronization.
18.4.5The total number of Network Elements cascaded from the stratum source
shall be minimized.
18.4.6A Network Element shall receive the synchronization reference signal only from
another Network Element that contains clock of equivalent or superior
quality (stratum level).

Page 52
Attachment 3
18.4.3.7U WEST shall select for synchronization those facilities shown to have the
greatest degree of availability (absence of outages).

synchronization facilities for synchronization related failures.
For non-SONET equipment, U WEST shall provide synchronization
facilities which, at minimum, comply with the standards set forth in ANSI
T1.101-1994.
For SONET equipment, U WEST shall provide synchronization facilities
that have time deviation (TDEV) for integration times greater than 0.
seconds and less than or equal to ten (10) seconds, that is less than or
equal to 100 nanoseconds. TDEV, in nanoseconds, for integration times
greater than ten (10) seconds and less than 1000 seconds, shall be less
than 31.623 times the square-root of the integration time.

INTERCONNECTION
Definitions
For purposes of this Attachment Interconnection" is the linking of the US WEST and
T& T networks for the mutual exchange of traffic. Interconnection does not include the
transport and termination of traffic. Interconnection is provided by virtual or physical
collocation, entrance facilities or meet point arrangements.
General Description
WEST will provide Interconnection at any technically feasible point, subject to
negotiations between the Parties; such points may include, but not be limited to, Meet
Point, the line side distribution frame of the local switch, the trunk side distribution frame
of the local switch, trunk interconnection points of the tandem switch, central office cross-

connect points, and Signaling Transfer Points necessary to exchange traffic and access
call related databases.
AT&T shall designate at least one POI in the LATA in which AT&T originates local
traffic and interconnects with US WEST. Where U S WEST demonstrates that such
point of interconnection is not technically feasible, U S WEST may disagree with the
point of interconnection, and the parties shall resolve such disagreement pursuant to
the ADR process set forth in this Interconnection Agreement. In addition, where U S
WEST can show that there exists a substantially more economical means for making
interconnection at a point that will provide AT&T with at least the same functionality
that would exist if the interconnection were made at the point and in the fashion
proposed by AT&T U S WEST may disagree with the point of interconnection, and
the parties shall resolve such disa~reement pursuant to the ADR process set forth in
this Interconnection Agreement. T& T will be responsible for engineering and
maintaining its network on its side of the POI. If and when the Parties choose to
interconnect at mid-span meet, T& T and US WEST will jointly provision the fiber optic
facilities that connect the two (2) networks and shall share the financial and other
responsibilities for that facility.
Within ten (10) Business Days of AT&T's request for any POI, US WEST shall provide any
information in its possession or available to it regarding the environmental conditions of the
interconnection route or location including, but not limited to, the existence and condition of
asbestos, lead paint, hazardous substance contamination, or radon. Information is
considered "available" under this Agreement if it is in US WEST's possession, or in the
possession of current or former agent, contractor, employee, lessor, or tenant of
WEST's.
US WEST shall allow T& T to perform any environmental site investigations, including, but
not limited to, asbestos surveys, T& T deems to be necessary in support of its collocation
needs. T& T shall advise US WEST in writing of its intent to conduct any such
investigations, and shall receive written approval from U WEST to proceed with the
investigation, which approval shall not be unreasonably withheld. T& T shall indemnify
WEST in accordance with the provisions of Section 18 of Part of this Agreement for
any loss or claim for damage suffered by US WEST as a result of T& T's actions during
any site inspection.
Location of Interconnection
T& T will be responsible for implementing and maintaining its network on its side of the POI.
WEST will be responsible for implementing and maintaining its network on its side of
the POI. If and when the Parties choose to interconnect at Meet Point, T& T and
WEST will jointly provision the fiber optic facilities that connect the two networks and
shall proportionately share the financial and other responsibilities for that facility based on
the reasonably negotiated Meet Point percentage.
If interconnection is complicated by the presence of environmental contamination or
hazardous materials, and an alternative route is available, U WEST shall make such
alternative route available for T& T's consideration.

Collocation
Interconnection may be accomplished through either virtual or physical Collocation. The
terms and conditions under which Collocation will be available are described in Part of this
Agreement.
Entrance Facility
Interconnection may be accomplished using an entrance facility without the need for
collocation. An entrance facility extends from the Point of Interface to point within
WEST central office.
Quality of Interconnection
US WEST will not, for the purpose of Interconnection, provide to T& T less favorable terms
and conditions than it provides Itself or any other Person or in manner less efficient than it
would impose on Itself or any other Person. The quality of Interconnection will be at least
equal to that US WEST provides to Itself or any other Person. To the extent that AT&T
requests higher or lower quality Interconnection T& T agrees to use the Bona Fide
Request process described in Part of this Agreement.
Points of Interconnection
Upon request for specific point to point routing, US WEST will make available to T& T
information indicating the location and technical characteristics of U WEST's network
facilities. The following alternatives are negotiable and include, but are not limited to: (a)
DS-1 or DS-3 entrance facility, where facilities are available (where facilities are not
available and U WEST is required to build special or additional facilities, special
construction charges may apply); (b) virtual collocation; (c) physical collocation; and (d)
negotiated Meet Point facilities. Each Party is responsible for providing its own facilities up
to the Meet Point. The Parties will negotiate the facilities arrangement between their
networks.
Trunking Requirements
WEST agrees to provide designed interconnection facilities that meet the same industry
standards for technical criteria and service standards, such as the probability of blocking in
peak hours and transmission standards.
8.2 The Parties shall initially reciprocally terminate local exchange
intraLA T A/interLA T toll calls originating on each other's networks as follows:

traffic on an aggregate basis. Trunks which carry only Local'Traffic
shall not be included in this calculation.
When Local Traffic is carried on trunks with IntraLATA/lnterLATA
Toll Traffic, at least 80% of such traffic shall be transported over
direct trunks from the AT&T switch to the U S WEST End Office
Switch. Trunks which carry only Local Traffic shall not be included
in this calculation.
verifiable and auditable means of assuring AT&T is
compliance with the preceding Sections 8.1 and 8.2 must be
provided by AT&T to U S WEST.
Management controls for network traffic shall be as specified in
Section 13 of this Attachment.
Untile the access structure is rS.Until the access structure is revised, to
accommodate non-segregated traffic pursuant to rules promulgated by the
FCC or the Commission, two-way trunk groups will be established wherever
practical, based upon T& T's request. If Local Traffic and Toll Traffic are
combined in one (1) trunk group, AT&T shall provide a measure of
the amount of Local and Toll Traffic relevant for billing ppurposes to U
S WEST. US WEST may audit the traffic reported to it by AT&T if it has
reason to believe the reported measurement is not accurate. Such audit
shall be conducted in accordance with the Audit Section set forth in
this Agreement.76 Exceptions to this provision will not be based on technical
infeasibility, but will be based on billing, signaling, and network rrequirements.
For example, exceptions include: (a) billing requirements switched access vs.
local traffic, (b) signaling requirements MF vs. SS7, (c) network requirements
Directory Assistance traffic to TOPS tandems, and (d) one-way trunks for
911/E911. The following is the current list of traffic types that require separate
trunk groups, unless otherwise specifically stated in this Agreement:

If U S WEST can demonstrate that any need for network reinforcement
would not be otherwise necessary but for the combined transport of CLEC
local and toll traffic through U S WEST's access tandem switch, it shall be
entitled to a sharing of the costs of such reinforcement; such cost-sharing
to be on a basis that is to be determined by agreement of the parties to be
equitable under the particular circumstances involved; provided, however
that any CLEC that is required to participate in such cost-sharing may, at
its election, transfer its local traffic to a separate trunk group in lieu of
participating in such cost-sharing arrangement.
Separate trunk groups will be established connecting T& T's switch or T& T's Operator
Service center to U WEST's Operator Service center for operator-assisted busy line
interrupt/verify. For traffic from the US WEST network to AT&T for Operator Services
US WEST will provide one (1) trunk group per LATA NPA serVed by the local US WEST
switch.

Trunk Servicing8.4
8.4.
8.4.
Orders between the Parties to establish, add, change or disconnect trunks shall be
processed by use of an Access Service Request ("ASR'? or another industry
standard for local service ordering.
As further described in this Agreement, both Parties will jointly manage the capacity
of Local Interconnection trunk groups. WEST's trunk servicing group will send
Trunk Group Service Request (TGSR'?, or another industry standard eventually
adopted to replace the TGSR, to T& T to trigger changes U WEST desires to the
Local Interconnection trunk groups based on U WEST's capacity assessment.
T& T will issue an ASR or other industry ordering standard to U WEST:
(a)within ten (10) Business Days after receipt of the TGSR, upon review of
and in response to U WEST's TGSR , or
(b)at any time as a result of T& T's own capacity management assessment
to begin the provisioning process. The interval used for the provisioning of
Local Interconnection trunk groups shall be no longer than the standard
interval for the provisioning of U WEST's Switched Access service and
shall be consistent with U WEST's actual provisioning intervals for its own
Switched Access customers.
WEST will attempt to meet T& T's requested due date for the provision of
Local Interconnect trunk groups. Where the installation of Local Interconnection
trunk groups is required within time that is shorter than the standard interval, the
Parties will make all reasonable efforts and cooperate in good faith to ensure that
the mutually agreed upon due date is met.
Orders that comprise major project may be submitted at the same time, in which
case their implementation shall be jointly planned and coordinated. Major projects
are those that require the coordination and execution of multiple orders or related
activities between and among US WEST and T&& T/MClm work groups

including, but not limited to, the initial establishment of Local Interconnection or Meet
Point trunk groups and service in an area, NXX code moves, re-homes, facility
grooming, or network rearrangements.
Trunking Requirements
Trunk group connections will be made at DS-1 or multiple DS-1level for exchange
of EAS/local, intraLA toll, wireless/Commercial Mobile Radio Service, and
Switched Access Traffic. Ancillary Service trunk groups will be made below DS-
level as agreed to by the Parties.
Where CCS is not available, in-band multi-frequency (MF) wink start signaling will
be provided. This MF arrangement will require separate local trunk circuit
between T& Ts switch and US WEST's tandems. Reference Technical Pub. TR-
314 and TR394.
The proper mix of direct trunked and tandem switched transport of DS-
equivalency (24 voice grade trunks) is a reasonable standard that the Parties
shall follow. A mix of direct-trunked and tandem-switched transport may
maximize the efficiency and economy of network operations. AT&T may, at its
option, examine pursuant to the BFA process whether (a) this standard is
unnecessary and causes it to bear significant expense in a particular case or
(b) experience and knowledge that it has gained over time under the
Interconnection Agreement show that a difference standard is appropriate.
Service Interruptions
Standards and procedures for notification of trunk disconnects will be jointly developed by
the Parties within ninety (90) days of the Effective Date of this Agreementafter request.
Neither Party shall be expected to maintain active status for trunk disconnected by the
other Party for an extended or indefinite period of time.
The characteristics and methods of operation of any circuits, facilities or equipment of either
Party connected with the services, facilities or equipment of the other Party pursuant to this
Agreement shall not: (a) interfere with or impair service over any facilities of the other Party;
its Affiliates, or its connecting and concurring carriers involved in its services; (b) cause
damage to their plant; (c) violate any applicable law or regulation regarding the invasion of
privacy of any communications carried over the Party s facilities; or (d) create hazards to the
employees of either Party or to the public.
Each Party shall be solely responsible, and bear the expense, for the overall design of its
services. Each Party shall also be responsible for any redesign or rearrangement of its
services that may be required because of changes in facilities, operations or procedures
minimum network protection criteria, and operating or maintenance characteristics of the
facilities. If one Party creates circumstance causing additional costs to the other Party, the
other Party may collect construction charges from the first Party.

To facilitate trouble reporting and to coordinate the repair of the service provided by each
Party to the other under this Agreement, each Party shall designate and define Trouble
Reporting Control Office (TRCO'? for such service. Each Party shall furnish trouble
reporting telephone number for the designated TRCO. This number shall have access to
the location where facility records are normally located and where current status reports on
any trouble reports are readily available. Current and historical trouble reports will be made
available, if necessary. Alternative out-of-hours procedures shall be established to ensure
access to location that is staffed and has the authority to initiate corrective action.
Where new facilities, services and arrangements are installed to rectify the service
interruption, the TRCO shall ensure that continuity exists and take appropriate transmission
measurements before advising the other Party that the new circuit is ready for service.
The Parties shall cooperate in isolating trouble conditions. Before either Party reports
trouble condition, it shall use reasonable efforts to isolate the trouble.
In cases where trouble condition affects significant portion of the other Party's service,
the Parties shall assign the same priority provided to other interconnecting carriers.
10.Forecasti ng79

10.
Interconnecting carriers and US WEST have an obligation to participate
joint planning meetings at quarterly intervals to establish trunk design and
provisioning requirements. The planning process shall will include the
issues of network capacity, forecasting, and compensation calculation,
where appropriate.
In order to support these planning meetings, the Parties agree to provide
mutual trunk forecast information to ensure customer call completion
between the Parties networks. Such forecasts will be for Local
Interconnection Service (LIS) trunking, which affects the switch hook
capacity of each Party. LIS trunk forecasts drive switch growth jobs that
provide switch hook capacity.
10.1 The Parties shall provide to each other quarterly forecasts that give
to the other all information that the recipient needs to plan, design,
and install on a timely basis all trunking facilities that are necessary
to exchange traffic between them.
10.At least two weeks prior to each joint planning meeting, both
Parties shall provide information on major network projects
anticipated for the following year, where such projects may affect
the other Party s forecast or interconnection requirements. Major
network projects include trunking or network rearrangements,
shifts in anticipated traffic patterns, or other activities that are
reflected by a significant increase or decrease in trunking demand
for the following forecasting period.

The quarterly forecasts shall include forecasted requirements for
each trunk group identified in Paragraph 8.1 of this Attachment.
In addition, for tandem-switched traffic, the forecast shall includethe quantity of tandem-switched traffic forecasted for each
subtending end office. For traffic terminated at a Party s access
tandem, the information shall include that which is required by the
party to plan for appropriate handling of the traffic. To the extent
historical traffic data can be shared between the Parties, the
accuracy of the forecasts will improve. Forecasts shall be for a
minimum of three (3) (current and plus-1 and plus-2) years.
10.4 The Parties recognize that many types of growth jobs generally
require a six (6) month minimum time frame for completion. The
Parties obligation to provide timely information for these jobs will
recognize this time frame.
10.5 The forecast, project, and supporting information provided in
writing or at planning meetings under this section shall be deemed
to be confidential and proprietary for purposes of Section 28 of this
agreement.
Each Party shall provide a specified point of contact for planning,
forecasting, and trunk servicing purposes.
Trunking can be established to tandems or end offices or a combination of
both via either one-way or two-way trunks. Trunking will be at the DS-
level, DS-1 level, DS-level, or at any other technically feasible level,
subject to network disclosure requirements of the FCC. Initial trunking will
be established between AT&T s switching centers and US WEST s access
tandem(s). The Parties will utilize direct end office trunking under the
following conditions:
10.Tandem exhaust - If a tandem through which the parties are
interconnected is unable to, or is forecasted to be unable to,
support additional traffic loads for any period of time, the
Parties will mutually agree on an end office trunking plan
that will alleviate the tandem capacity shortage and ensure
completion of traffic between AT&T and US WEST
subscribers.
10.Traffic volume - The Parties shall install and retain direct end office
trunking sufficient to handle actual or reasonably forecasted traffic
volumes, whichever is greater, between an AT&T switching center
and a US WEST end office where the local traffic exceeds or is
forecasted to exceed 512 CCS at the busy hour.
10.Mutual agreement - The Parties may install direct end office
trunking upon mutual agreement in the absence of conditions (1) or
(2) above, which agreement shall not unreasonably be withheld.
USWC/AT&T Interconnection Agreement -Idaho 08/0598
Attachment 4
Page 9
10.The Parties shall have a mutual obligation to work to resolve forecast
differences within a time frame that will permit the timely construction of
facilities that are necessary to meet forecasts. This obligation shall include
good faith efforts to institute and complete the use of the dispute
resolution procedures of Section 27 to resolve such differences. Upon the
request of either Party, the Parties shall negotiate in good faith to develop
expedited rules and procedures that will allow the use of Section 27
procedures to resolve forecast differences on a basis that will permit the
timely construction of facilities that may prove necessary.
10.Compensation in the Event of Capacity Surpluses
The constructing Party may seek compensation for the actual cost of construction
of facilities that prove unnecessary under the following conditions:
(A) One party, not necessarily the one seeking compensation under this
provision, must have promptly requested resolution of forecast differences
under Section 10.5 above.
(B) The initiation of such a request under Section 10.5 shall be sufficient
notice to each Party that it is at risk of having to make compensation under
this section, whether or not such request comes to final resolution by a
third party on a timely basis.
(C) Compensation to the constructing Party shall only be awarded if greaterthan 20 percent (in addition to any spare or reserve capacity already
included as a result of the application of demonstrable planning guidelines
or criteria) of the capacity in the constructed facilities is actually unused
because of an over-forecast by the other Party. For example, no
compensation is to be awarded if capacity unused due to the over-forecast
is 20 percent. If such unused capacity is 25 percent, then the constructing
Party shall be entitled to payment for all 25 percent of such capacity.
Moreover, usage of the facilities by all parties, including but not limited to
the constructing Party and any persons not party to this agreement, shall
be accumulated for purposes of determining the used portion of such
facilities. The basis for measuring the difference in actual versus
forecasted capacity at each point in time shall be made by comparing
actual use at that time against use forecasted to exist at that time.
(D) The constructing Party shall be obliged to show that it has undertaken
reasonable means to mitigate the revenue impacts of such unused
capacity.
(E) The Party responsible for making compensation under this section shall
have the right to elect to make a one-time payment of the fully allocated
costs of such unused capacity or to make recurring payments at prices set
forth in this agreement. In the case of the former election, the Party so
responsible shall have the right to use the capacity without further charge
for the capacity itself (as opposed to its operation and maintenance) by the
USWC/AT&T Interconnection Agreement -Idaho 08/0598
Attachment 4
Page 10
constructing Party. In the case of the latter election, the constructing Party
shall have the continuing obligation to mitigate revenue impacts and it shall
credit the other Party at the prices set forth in this agreement for all use of
such capacity by any other person, including but not limited to the
constructing Party and any persons not party to this agreement.
10.Compensation in the Event of Capacity Shortages
Regardless of the level of facility needs determined through forecasts, the Parties agree
that they will undertake the following measures upon request of the other to provide LIS
trunking facilities to meet any actual unmet needs:
(A) Release the Party s own underutilized trunks for the purpose of
providing sufficient interconnection capacity between them.
(B) Request that other providers release unneeded trunks to which they are
entitled to have access ( brokering). The brokering process will be
conducted in a manner that does not result in the disclosure of either Party
s confidential or proprietary information to third parties, including such
other providers.
(C) Expedite trunk installation or augmentation.
10.Where the unmet needs are among needs that can be shown to be
included within (a) an agreed upon forecast or (b) a forecast level
determined to be appropriate through the dispute resolution
procedures described in Section 10.5, there shall be no recoveryfrom the other Party for the costs of taking any of the
aforementioned three measures. Where the unmet needs exceed
those included in either of the above two types of forecasts, a Party
who requests the other to take either of those measures shall pay to
the other Party its reasonable costs for undertaking those measures
that are undertaken at the direction of the requesting Company.
10.In addition to the measures set forth in section 10.1, a Party that
requests LIS trunking facilities in excess of a forecast such as those
described in section 10.1 may select the following options:(A) Cancel its request.
(B)Pay the other Party s reasonable costs for expedited
construction of the additional facilities.
10.Where there has been neither of the two types of forecasts
described in section 10., a Party who requests facilities in excess
of those that would have been required to meet its forecast shall be
liable to bear the cost of efforts to mitigate the impacts of an actual
shortage under the following conditions:

Attachment 4
Page 11
(A) One party, not necessarily the one seeking compensation under
this provision must have promptly requested resolution of forecast
differences under Section 10.5 above.
(B) The initiation of such a request under Section 10.5 shall be
sufficient notice to each Party that it is at risk of having to make
compensation under this section, whether or not such request
comes to final resolution by a third party on a timely basis.
(C) Compensation shall only be awarded to the extent that the
forecast of the requesting Party is determined to be greater than
what was reasonable at the time that the requesting Party made it.
Moreover, compensation shall be limited to the mitigation costs; the
prices for the trunking itself shall be as provided elsewhere in this
agreement, in order to preclude double compensation.
In the event that the parties agree to a forecast, or in the event that their
differences with respect to a forecast are resolved under Section 27
procedures in a manner that supports timely capacity installations, neither
Party shall be liable to the other for compensation related to capacity
surpluses or shortages, except in either of the following two situations:
where a Party can demonstrate that the other Party s grossly
negligent or intentional errors or omissions contributed
substantially to the production of such an agreed to or resolved
forecast.
where circumstances beyond the control of either Party result in the
failure of forecasted demand arise and a constructing Party is left
without reasonable assurances that it will be able to recover its
investment in the constructed facilities during their expected life.
The compensation provisions of this section shall not be construed to
diminish any rights that a Party may have to compensation or damages
under any other provision of this agreement.

10.Interconnecting Carriers have an obligation to participate in joint planning
meetings, at quarterly intervals to establish trunk design and provisioning
requirements. The Parties agree to provide mutual trunk forecast information to
ensure customer call completion between the Parties' networks. Such forecasts
will be for Local Interconnection Service (LIS) trunking, which impacts the switch
hook capacity of each Party. LIS trunk forecasts drive switch growth jobs that
provide switch hook capacity.

Switch growth jobs are custom jobs with a six (6) month minimum
time frame from the vendors. To align with the timeframe needed to
provide capacity, including engineering, ordering, installation
and make-ready activities required by the forecast, the Parties
agree to utilize the attached timeline (attachment 1, example
only) and appropriate LIS Trunk Forecast Forms.
Each Party will utilize the Forecasting Advance Interval, whichcovers a seven (7) month forecast, (provided according to the
above mentioned timeline), as though it were building for actualorders.
Co-Providers will follow the contractual agreements for
appropriate trunking; for the appropriate sizing of trunks and
local tandem and end office routing. In the event of a dispute of
forecast quantities, the Parties should build to at least the
minimum, rather than not building at all.
Joint planning meetings/calls will be used to bring clarity to theprocess. Each Party will provide adequate information associated
wi th the forecast questions, in addition to its ' forecasts.During the j oint planning meetings, both Parties shall provide
information on major network projects anticipated for the
following year , which may impact the other Party s forecast orinterconnection requirements. No later than two weeks prior to
the joint planning meetings, the Parties shall exchange
information to facilitate the planning process.

intraLA T toll, or Switched Access.
17.4 Transport and Termination of Exchange Traffic
17.4.Termination of Local Traffic
Local Traffic will be terminated pursuant to the Reciprocal Compensation described
in Attachment 1. AT&T is not entitled to charge the tandem rate for transport
and termination.
17.4.EAS/Local Traffic
As negotiated between the Parties, the exchange of local traffic between the Parties
may occur in several ways.(a) While the Parties anticipate the use of two-way trunks for the delivery of
Local Traffic, either Party may elect to provision its own one-way trunks for delivery
of Local Traffic to be terminated on the other Partys network at the "initial" point of
Interconnection;(b) The Parties may elect to purchase transport services from each other or
from third party. Such transport delivers the originating Party's Local Traffic to the
terminating Partys end office or tandem for call termination. Transport may be
purchased as either tandem switched transport (which is included in the tandem call
termination rate) or direct trunk transport;
(c) To the extent that AT&T has established Collocation arrangement at
WEST end office location, and has available capacity, the Parties agree that
T& T shall provide two-way direct trunk facilities, when required, from that end
office to the T& T switch. In all other cases, the direct facility may be provisioned
by US WEST or T& T or third party. If both T& T and US WEST desire to
provision the facility and cannot otherwise agree, the Parties may agree to resolve
the dispute through the submission of competitive bids.
17.4.Transit Traffic
17.4.WEST will accept traffic originated by T& T and will terminate it at
point of interconnection with another CLEC, Exchange Carrier, IXC or Wireless
Carrier. US WEST will provide this transit service through Tandem Office
Switches. T& T may also provide U WEST with transit service.
17.4.2The Parties expect that all networks involved in transporting Transit Traffic
will deliver calls to each involved network with CCS/SS7 protocol and the
appropriate ISUP/TCAP message to facilitate full interoperability and billing

functions. In all cases, the originating company is responsible to follow the EMR
standard and to exchange records with both the transiting company and the
terminating company, to facilitate the billing process to the originating network.
17.4.3The Parties will use industry standards developed to handle the provision
and billing of Switched Access by multiple providers (MECAB, MECOD and the
Parties' FCC tariffs).
17.4.4 Toll Traffic
Toll Traffic routed to an access tandem, or directly routed to an end office, will be
terminated as Switched Access Service.
Interface Code Availability And Optional Features
17.Interface Code Availability
Supervisory Signaling specifications, and the applicable network channel interface
codes for Local Interconnection trunks, are the same as those used for Feature
Group D Switched Access Service, as described in the Parties' applicable Switched
Access tariffs.
17.Optional Features
17.Inband MF or SS7 Out of Band Signaling
Inband MF signaling and SS7 out of band signaling are available for local trunks.
MF signaling or SS7 out-of-band signaling must be requested on the order for the
new local trunks. Provisioning of the local trunks equipped with MF signaling or
SS7 out of band signaling is the same as that used for Feature Group D Switched
Access. Common Channel Signaling Service, as described in this Agreement, must
be ordered by T& T when SS7 out-of-band signaling is requested on local trunks.
17.5.2.Clear Channel Capability
Clear channel capability permits 24 DS-64 kbit/s services or 536 Mbit/s of

2. 17.Customer has the ability to escalate.
6.2. 18 WEST shall provide for resale any maintenance/protection plans for services
offered under this Agreement to T& T that it offers US WEST's own Customers.
WEST's current trouble reporting system does not provide the capability to
reopen closed trouble report. Therefore, US WEST shall allow T& T to
designate that trouble report is associated with the initial trouble report which was
closed in the past twenty-four (24) hours without repairs being performed to the
Customers satisfaction. U WEST shall measure the frequency of these types of
repeated reports and will demonstrate non-discriminatory treatment to T& T.
20 Additional Unbundling Requirements
6.2.20. When trouble is reported by Customer served through unbundled
Network Elements T& T will test its network to identify any problems. If
no problems are identified with the T& T network T& T will open
trouble report with U WEST and provide switch-based test results to
the U WEST technician. US WEST shall then test its portion of the
network and perform repairs as required in the time frames set forth
below in this Attachment.
20.If U WEST tests the unbundled loop and no trouble
found ("NTF'j, the same shall be reported back to
T& T. If, upon testing the unbundled loop, the trouble is
isolated to the Customer side of the NID (inside wire
CPE, etc.
),
AT&T shall be billed trouble isolation

updates to T& T. For trouble isolation both Parties will
cooperatively test to isolate the trouble as required.
Systems Interfaces and Information Exchanges
US WEST shall cooperate with AT&T to establish real-time, electronic interface by
T& T to US WEST's maintenance systems and databases. This system shall be
based on existing and future uniform industry standards being worked in T1
standards committee and Electronics Communications Implementation Committee
("ECIC'J industry forum.
An electronic bond will be system to system connection with immediate
update capability. In no way shall this interface cause T& T personnel to
use U WEST systems via remote hook up or any other means of access.
1.2 This interface shall allow T& T personnel to perform the following functions
for T& T Customers: (i) enter trouble reports in the US WEST
maintenance systems for an T& T Customer, (ii) retrieve and track current
status on all T& T Customer trouble report; (iii) receive "estimated time to
repair" (ETTR) on real-time basis; (iv) receive immediate notification in
the event repair person is unable to be present for, or anticipates missing,
scheduled repair appointment, and (v) retrieve all time and material
charges that apply to T& T at the time of ticket closure (itemized by time
spent, price of materials used, procedures employed, amounts incurred in
each such category, and total by Customer, per event (vi) receive
automated notification of case closure.
Automated interfaces must be provided into centralized operations
support systems data base for real time network monitoring to proactively
identify potential service degradation. Such systems must monitor and
report on the integrity of the U WEST network, isolate trouble and where
applicable (e., when an unbundled loop is connected to an unbundled
port or when an unbundled loop includes such equipment as DCS, D4
etc.), initiate repair operations, test individual unbundled loops and generate
maintenance and repair notices that impact any end user's ability to
complete calls. Ongoing maintenance practices on such unbundled loops
must be equal to or exceed the practices employed by U WEST for
facilities used to provide Services For Resale.
1.4 US WEST agrees to develop and implement, as soon as possible, with
target date of November , 1997 the electronic interfaces described
above.
3.2 WEST agrees that T& T may report troubles directly to single U WEST
Repair/Maintenance Center for both residential and business Customers. The
Repair Center will have two separate numbers, one for residence and one for
business. CLEC's will be treated in the same manner as WEST customers.
WEST shall perform all testing for Resale Services. U WEST shall provide
the capability for T& T to receive ML T test results while T& T customer is on line
during the initial trouble report, when technically feasible in the U WEST network.
