The following langua_ge is added to the existin_g language, in the Agreement, in its
entirety:
Definitions
Carrier Partner is a Certified Local Exchange Carrier (CLEC) that provides the facilities and
trunking that an Interconnected VoIP Provider needs in order to exchange traffic with CenturyLink
and demonstrates facilities readiness as described in the VoIP Numbering Order.
Denial of Service (DoS) is an action that prevents legitimate user(s)from using or being provided
service.
Interconnected VoIP Provider is an entity that provides interconnected VolP service, as that term
is defined in 47 C.F.R. §9.3 and that obtains numbering resources as described in the VoIP
Numbering Order.
Terms of Carrier Partner Amendment
1. Pursuant to the terms of this Amendment, CLEC will be exchanging with CenturyLink
VoIP-PSTN Traffic, Transit and Jointly Provided Switched Access traffic of Interconnected VoIP
Providers on the CLEC's interconnection trunks.
1.1 Prior to CLEC exchanging traffic for an Interconnected VolP Provider with
CenturyLink, CLEC will notify CenturyLink and CenturyLink will confirm that the
Interconnected VoIP Provider has entered into an "Interconnected VolP Provider
Numbering Agreement" with CenturyLink.
1.2 CLEC will notify CenturyLink when CLEC is no longer routing an Interconnected
VoIP Provider's traffic on CLEC's interconnection trunks.
1.3 CLEC will provide such notifications to their CenturyLink Customer Account
Manager (CAM).
1.4 CLEC will follow applicable procedures of the LERG and the Agreement in order
to identify the OCNs and NPA-NXX(s) of the Interconnected VoIP Provider which
will be associated with the CLEC's Switch and routed on the CLEC's
interconnection trunk groups.
1.5 The Interconnected VoIP Provider may use a POI CLLI for code entry in LERG 6
and they must also designate the responsible CLEC Carrier Partner's end office
CLLI as the Actual Switch ID in LERG 7 SHA.

ATTACHMENT 1
1.6 Should CLEC Carrier Partner utilize a third-party switch, the CLEC Carrier Partner
must establish trunking between the third-party switch and CenturyLink per the
terms of the Interconnection Agreement ("Agreement"). In addition, the CLEC
Carrier Partner may not exchange traffic over its trunks with Centurylink on behalf
of the third-party switch owner.
2. CLEC and CenturyLink will continue to exchange traffic under the terms of the Agreement,
including treatment of traffic terminating to CenturyLink end users. Solely for purposes of this
Amendment, all traffic originated by parties utilizing CLEC and terminating to CenturyLink end users
or transiting CenturyLink to other providers will be treated as though originated by CLEC, including
but not limited to terminating intercarrier compensation, Transit compensation, compensation for use
of interconnection transport facilities, and establishment of direct trunk groups.
3. No compensation for transiting traffic will be paid by CenturyLink to CLEC for traffic that
CenturyLink sends through the CLEC to terminate to Interconnected VoIP Provider. All CenturyLink
end user traffic will be treated as though it was terminated with the CLEC.
4. Interconnected VoIP Provider traffic will be included as the CLEC's responsibility in
accordance with applicable terms of the Agreement.
5. This Amendment does not otherwise modify or supersede the terms and conditions of any
agreement that CLEC may have with CenturyLink, including tariff, Interconnection and/or other
agreements.
6. This Amendment does not authorize CLEC to bill CenturyLink on behalf of Interconnected
VoIP Provider for any charges associated with transit traffic, terminating traffic or interconnection
facilities, including, but not limited to any compensation arrangements contained in separate
agreements or tariffs with CenturyLink.
7. CLEC will pass unaltered signaling information (e.g., originating Calling Party Number and
destination called party number, etc.) for the Interconnected VoIP Provider's traffic per 47 C.F.R. §
64.1601 and industry standards.
8. CLEC agrees that CenturyLink may discontinue accepting all traffic delivered over CLEC's
trunking where CenturyLink experiences from Interconnected VoIP Provider a Denial of Service
(DoS) attack or such Interconnected VoIP Provider traffic otherwise contributes to the degradation
of CenturyLink's network or CenturyLink's ability to provide service to its customers. CLEC agrees
to remove the inappropriate Interconnected VoIP Provider traffic from its network prior to
CenturyLink's subsequent acceptance of CLEC's other traffic. Following any such event, CLEC will
establish a separate trunk group for the Interconnected VoIP Provider's exclusive use for any
subsequent Interconnected VoIP Provider traffic.
9. Where CLEC agrees to allow its interconnection trunks with CenturyLink to also be used
for the routing of Interconnected VoIP Provider's traffic, CLEC will ensure traffic routed over such
trunks is destined solely to the geographic area served by CenturyLink's switch as defined in the
LERG.

10. CLEC agrees that CenturyLink will not be responsible to provide 911 services directly to
the Interconnected VoIP Provider and that instead CLEC will be responsible as the Carrier Partner
to provide such 911 services in accordance with applicable terms of the Agreement.
11. If CLEC chooses to obtain numbering from NANPA under a different OCN as an
Interconnected VoIP Provider, they must have both a Commercial Interconnected VoIP Provider
Numbering Agreement and this Amendment in order to route their Interconnected VoIP Provider
traffic associated with that OCN on CLEC's interconnection trunks.
