COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 10 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges 2.5.1 General The charge for a private line service may be a recurring and/or a nonrecurring charge. 2.5.2 Application of Charges The charges billed are based on the rates that are in effect in this tariff during the period that the private line service is furnished.If the rates for a period covered by a bill change after the bill has been rendered,the bill will be adjusted to reflect the new charges (see Fractional Charges and Credits within this tariff). 2.5.3 Payment of Charges Payment is due upon presentation of a bill for the private line service furnished.A private line service may be discontinued for nonpayment of a bill (see Violation of Regulations within this tariff). An administrative charge of $6.00 will be applied by CNT each time a check or bank draft is returned by a bank to CNT for the reason of insufficient funds. 2.5.4 Minimum Payment Period and Notice of Discontinuance A.Minimum Payment Period The minimum payment period is the minimum period for which the customer is required to make payment for the private line service.The charges applicable to the minimum payment period include the recurring charge(s)plus any nonrecurring and/or special construction charge(s)that may apply. The minimum payment period is calculated from the date that billing started after (1)the initial installation,or (2)a reinstallation after a change. Minimum payment period charges apply if the customer discontinues a private line service component before the specified minimum payment period expires.The minimum payment period for a given private line service component is specified in the section of this tariff applicable to that private line service component. B.Notice of Discontinuance CNT requires notice when private line services are to be discontinued.The required notice period and the application of charges,if any,are specified in the section applicable to the specific private line service.(Under certain conditions,this notice requirement may be waived.) COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 11 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.5 Advance Payments and Deposits A.Advance Payment An advance payment may be required before a private line service is provided when a customer has a history of late payments to CNT or when a customer's financial responsibility is not a matter of record.The advance payment will equal the charges for the minimum payment period and the applicable nonrecurring charges.In addition,the advance payment will include an amount equal to the estimated nonrecurring charges and one month's recurring charges (if any)when special construction is involved.The advance payment will be credited on the customer's bill(s).A deposit may apply in addition to an advance payment (see Deposits,following). B.Deposits To safeguard its interests,CNT may require a customer with a history of late payments to CNT or whose financial responsibility is not a matter of record to make a deposit to be held as a guarantee for the payment of charges.A deposit does not relieve the customer of the responsibility for the prompt payment of bills on presentation.The deposit will not exceed an amount equal to the sum of the charges for the minimum payment period for the private line service. If a termination charge or a maximum termination liability is specified,the deposit may include an additional amount.This additional amount will not exceed the maximum charge(s)specified for the termination charge or maximum termination liability.An advance payment may be required in addition to a deposit (see Advance Payment,preceding). 1.Interest on a Cash Deposit The deposit will bear simple interest at the rate currently effective by order of the Idaho Public Utilities Commission,payable on the actual amount of deposit with the Company. 2.Return of a Deposit A deposit will be credited to a customer's account,and any credit balance remaining will be refunded,when the customer has established credit,or when the customer has established a prompt payment record with CNT for one year,or when the private line service for which the deposit had been required is discontinued. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 12 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.6 Types of Charges There are two types of charges,recurring and nonrecurring.These charges are as follows: A.Recurring Charges The recurring charges for a private line service are listed in the applicable service section as: 1.Monthly Charge A monthly charge applies each month or fraction thereof that a private line service is furnished. Monthly charges start on the day after the private line service is installed but not before the due date of the order unless the customer agrees to an earlier installation.Charges accrue through and include the day that the private line service is discontinued.Monthly charges will be billed in advance.When the billing date and the date that the private line service is started,changed,or discontinued do not coincide,the charges will be adjusted to reflect the fractional part of the month involved (see Fractional Charges and Credits,within this tariff).For billing purposes each month is considered to have 30 days. B.Nonrecurring Charges A nonrecurring charge applies for an activity,such as an installation,a move,or a change, ordered by the customer.A nonrecurring charge applies for each activity performed.The charge may differ according to the work activity involved.Other charges,such as termination charges,if applicable,are also classified as nonrecurring charges.In addition,other charges for specific functions as stated in this tariff are applied on a nonrecurring basis.Following is a description of the generic nonrecurring charges. 1.Installation Charge An installation charge applies when a private line service is furnished.Installation charges are listed in the appropriate sections of this tariff.Installation charges may be further categorized as follows: a."First"denotes an installation charge for the first service of a group of identical services ordered at the same time and installed at the same time for the same custorner and at the same location. b."Additional"denotes an installation charge for each additional service--excluding the first- -ordered at the same time and installed at the same time for the same customer and at the same location. c."Initial"denotes an installation charge for options installed at the same time as the primary service with which they are associated. d."Subsequent"denotes an installation charge associated with an option added to an existing service.

When a component with a termination charge is moved,the customer must pay the unexpired portion of the termination charge.A new termination charge will be established at the new location.A move normally involves an interruption of the private line service for the period required to complete the move.No credit allowance will be granted for the period. When a customer requests the installation of a duplicate service to avoid interruption during a move,recurring and nonrecurring charges will apply for the duplicate service.Charges will commence when the duplicate service is furnished.A new minimum payment period will apply for the duplicate service. a.Moves in the Same Building When a local channel service is moved to a new location in the same building at the customer's request,a move charge applies.A move charge is equal to one-half,except for Digital Data Local Channel Services where whole charges apply,of the installation charge for the local channel service involved,including the access coordination function and any channel options, miscellaneous equipment and arrangements that are associated with the service at that building. b.Moves to a Different Building When a local channel service is moved to a different building (or to a different central office)at the customer's request,the move is considered to be the discontinuance of the local channel service at the former location and the installation of a local channel service at the new location. The installation charges for the local channel service apply.Installation charges also apply to the access coordination function and any channel options and miscellaneous equipment or arrangements (with stated installation charges)associated with the service required at the new location.A new minimum payment period will be established for the local channel service.If a move to a new designated Central Office is not made at the customer's request,but is required as a result of CNT's rearrangement of its network,move charges do not apply.

The termination charge is determined by multiplying the dollar amount by the ratio of the unexpired portion of the specified period of time.A description and example of the process for determining termination charges follows. a.Identify the number of months in the specified period as shown in brackets following the dollar amount,e.g.,[60]=60 months. b.Identifythe number of months that the private line service has been furnished,including fractions of months. c.Subtract the number of months the private line service has been furnished from the number of months in the specified period to obtain the unexpired portion of the specified period (a-b). d.Divide the unexpired portion of the specified period by the specified period to obtain the charge ratio to be used (c divided by a). e.Multiply the dollar amount by the charge ratio to obtain the charge to be made (termination charge amount x d). Example: Dollar Amount =$60,000 Specified Period {}={60}months Time Furnished =40 months COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 15 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.6 Types of Charges (Cont'd) B.Nonrecurring Charges (Cont'd) 3.Termination Charge (Cont'd) Step 1:Unexpired Portion of Specified Period = Specified Period -Time Furnished 60 -40 =20 Step 2:Charge Ratio = Unexpired Portion of Specified Period Specified Period 20 =1/3 Step 3:Charge To Be Made = Dollar Amount X Charge Ratio 60,000 x 1/3 =$20,000 2.5.7 Cancellation,Delay,or Change of an Order The regulations set forth in this section for the cancellation,delay,or change of an order apply to all private line service components. Change of a Due Date When an order for a private line service is placed,a due date will be established and confirmed with the customer.In the event that a due date is changed as set forth in A.,B.,or C.following, the due date for the order will be changed to reflect the number of days of delay or advance,as appropriate. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 16 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.7 Cancellation,Delay or Change of an Order (Cont'd) A.Delay of a Due Date by the Customer A customer may delay the due date of an order involving the installation,move or rearrangement of a private line service when:Section 2.5.7.B.is not applicable and the request for the delay is received by CNT prior to the order's due date,and the total delay measured from the order's initial due date does not exceed 30 cumulative calendar days.When the due date is delayed,a due date change charge will apply.Orders involving the discontinuance of a private line service may be delayed at any time prior to the due date.There will be no maximum delay period for these orders. 1.Maximum Delay Period When the customer has delayed an order for the maximum 30 cumulative calendar day period, the order may not be delayed again by the customer.In such case,unless B.following applies, the customer has the option to (1)accept billing for the private line service ordered,or (2)cancel the order and pay the applicable cancellation charge for the private line service ordered.The billing or cancellation is effective on the 30th cumulative calendar day of the delay. If the customer elects to accept billing,the installation will be completed as soon as reasonably practical after the customer advises CNT that the installation can be completed. B.Delay of a Due Date by CNT CNT will make every reasonable effort to assure that the private line service ordered is furnished on the due date.However,in some cases a delay in the installation may be unavoidable.If an order is delayed beyond its due date for more than 30 cumulative calendar days and such delay is not requested or caused by the customer,the customer may cancel the order without cancellation charges applying.

D.Cancellation of an Order A critical date schedule is established by CNT for each private line service order placed by a customer.CNT uses this schedule to identify key activities in the service order process,to monitor the progress of the installation,and to administer the schedule of cancellation charges. Critical date schedules may vary between service orders.The specific critical dates that have been established for a given order can be obtained from the customer's CNT sales negotiator. The critical dates monitored by CNT are: Application Date (APP):The date on which the customer provides a firm commitment and sufficient information to CNT to proceed with issuance of a firm order for service. Scheduled Issue Date (SID):The date on which the service order is entered into CNT's service order distribution system.Design Layout Report Date (DLRD):The date on which the Design Layout Report (DLR)or access interface information is received by CNT from the LEC. Records Issue Date (RID):The date on which all circuit design and assignment information is sent to the central office installation force. Wired and Office Tested Date (WOT):The date by which all intraoffice wiring is completed,all plug-ins are optioned and aligned,and frame continuity is established. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 18 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.7 Cancellation,Delay or Change of an Order (Cont'd) D.Cancellation of an Order (Cont'd) Critical Dates (Cont'd) Circuit Test and Acceptance (CTA)Date:The date on which overall testing of the service is completed. Due Date (DD):The date that has been established for completion of the service installation. If an order for private line service is canceled by the customer prior to the SID,no charge applies. For cancellations by the customer on or after the those dates,a cancellation charge will apply. The amount of the cancellation charge will vary according to the category of service ordered and the date reached in the critical date schedule.Cancellation charges applicable to the components of each category of private line service are listed in the service specific sections of this tariff. If the customer or CNT delays the due date of an order,in accordance with 2.5.7.A.or B. preceding,the critical date schedule for the order will be revised for those critical dates not yet passed.Subsequent cancellation of the delayed order by the customer will cause a cancellation charge based on the revised schedule to be incurred. E.Cancellation Involving Special Construction If a customer cancels an order that involves special construction,the applicable charges for the special construction,described within this tariff,apply in addition to the cancellation charges,herein described. F.Change of an Order When a customer changes the office connection or the channel options on an order before the due date,such a change is considered to be a design change.A Design Change Charge applies as specified in this tariff (see Design Change Charge within this tariff).A change in the location of an IOC is considered to be a cancellation of the order.If the change does not involve all portions of a private line service but causes the remainder of the service to be delayed more than 30 days beyond its due date,the customer has the option of (1)accepting billing for the components on the remainder of the service or (2)canceling those components and paying the applicable cancellation charge. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 19 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.7 Cancellation,Delay or Change of an Order (Cont'd) G.Other Changes to an Order When a customer changes (1)the point of local channel termination on a premises (including changes involving the addition or removal of inside wire),(2)the interface,or (3)the channel options on an order before the service date,such a change is considered to be a design change. A design change charge applies as specified in this tariff (see Design Change Charge,Section 13).A change in premises is considered to be a cancellation of the order for the local channel service.If the change does not involve all locations on a local channel service but causes the remainder of the locations to be delayed more than 30 days beyond their due date,the customer has the option of (1)accepting billing for the remaining locations or (2)canceling those locations and paying the applicable cancellation charge. A customer's order for modification of private line service after the service date is considered to be a change in service arrangement,as specified within this tariff. 2.5.8 Change in Service Arrangement When a customer requests that private line service be changed after the service date,charges are determined in accordance with A.and B.following. A.When Charges Apply Charges apply for the following changes: 1.A change of an interoffice private line service from one transmission speed or bandwidth to another is considered to be the discontinuance of one interoffice private line service and the installation of a new interoffice private line service.Installation charges apply for the new private line service and a new minimum payment period is established. 2.A change in the office connection or a change in conditioning is considered to be the discontinuance and reinstallation of the interoffice private line service involved.Installation charges for the changed components,as appropriate,apply.A new minimum payment period is not established.Installation charges for components continued in use do not apply.A component is considered to be continued in use if (1)there is no break in billing for the recurring charge(s)for the component(s),(2)the component is not changed. 3.For all other changes to an interoffice private line service,excluding those changes identified in B. following,the installation charge for the component involved applies.

Example:Private line service furnished/discontinued on the 15th day of a 30-day month. Monthly Charge =$1,000 Number of Days Remaining in Billing Period =15 days Billing Month =30 days Fractional Monthly No.of Days Remaining Charge/Credit =in Billinq Period X Monthly Charge Billing Month Fractional Monthly =15 x $1,000 Charge/Credit 30 Fractional Monthly Charge/Credit =$500 In the above example,the number of days remaining in the billing period would be 13 for a 28-day month and 16 for a 31-day month.The same process would be used for computing the fractional monthly charge or credit.

Example:Rate change effective on the 12th day of the 28-day month. Old Monthly Charge =$1,000 Number of Days Remaining in Billing Period =17 days Billing Month =30 days Fractional Part of Month =2 Billed at the new rate 30 Rate Change =$60 monthly increase Fractional Charges or Credit =Ex $60 =$34 for the Rate Change 30 Billing for the Month in which the Rate Change Occurred (for a rate decrease subtract the fractional charges)=$1,000 +$34 =$1,034 Subsequent New Monthly Charges =$1,000 +$60 =$1,060 COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECTON2 EFFECTIVE:ORIGINAL PAGE 23 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.9 Fractional Charges and Credits (Cont'd) B.Computing Fractional Charges or Credits for a Rate Change (Cont'd) In the above example,the number of days remaining in the billing period would be 19 for a 30- day month and 20 for a 31-day month.The same process would be used for computing the fractional monthly charge or credit. C.Rounding to the Nearest Cent If the computed charge(s)or credit include one-half cent or more,the fractional is rounded up to the next higher cent.Fractions of less than one-half cent are disregarded. 2.5.10 Special Taxes,Fees,Charges Any assessments,franchise fees,privilege,license,occupation,excise,or other similar taxes or fees,whether in a lump sum or at a flat rate,or based on receipts,or based on poles,wire or other utility property units,imposed upon CNT by any governmental authority subsequent to the effective date of this tariff shall be added pro rata,insofar as practical,to the rates and charges stated in the standard schedules,in amounts which in the aggregate for the customers of any political entity shall be equal to the amount of any such tax upon CNT.CNT shall,so long as any such tax or fee is in effect,add to the bills of the customers in such political entity a pro-rate on the basis of the revenue derived by the company from each such customer,an amount sufficient to recover any such tax or fee. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECTON2 EFFECTIVE:ORIGINAL PAGE 24 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.11 Special Access Surcharge A.A Special Access Surcharge applies to each termination of a channel service at a PBX or equivalent device capable of interconnecting the channel with the local exchange network.The surcharge applies to each two-point local channel,to each multipoint termination at a customer's location,and applies to analog and digital high capacity service on a per voice grade equivalent basis. CNT will bill the customer for the surcharge on each channel service termination unless the customer certifies that the channel service termination is exempt from the surcharge.This charge will be billed automatically on each special access service installed irrespective of whether the interconnection capability exists in the customer's premises equipment or in a Centrex-CO type switch.The surcharge rate is specified in the applicable rate sections of this tariff. B.Exemptionsfrom the Surcharge 1.A customer's channel service termination will be exempted from the monthly surcharge if the customer certifies to CNT that: a.The channel service is terminated in a device which is not capable of interconnecting the service with the local exchange network,or b.The channel service termination is associated with Switched Access Service that is subject to Carrier Common Line charges. 2.Certification must be provided by the customer when the channel service is ordered or changed. If a certification is not received from the customer with the order or change of service,the surcharge will be applied. 3.If the customer's service termination cannot be exempted as certified,the company reserves the right to bill and/or back bill the customer as necessary,including any penalty charges that may accrue to the Company. C.Crediting the Surcharge Upon receipt by CNT of certification that the customer's channel service termination is exempt from the surcharge,as specified in B.preceding,CNT will not bill the customer at the location certified as exempt. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECT ON 2 EFFECTIVE:ORIGINAL PAGE 25 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.5 Payments and Charges (Cont'd) 2.5.12 Late Payment Charge Subject to billing and systems availability,when a bill or estimated bill for private line services charges is presented to the Customer,any amounts for which payment has not been received within 30 calendar days of the invoice date will be considered delinquent.The Customer shall be assessed a Late Payment Charge on any delinquent account balance,when that balance exceeds $25.00.The minimum late Payment Charge is $5.00.The period subject to the Late Payment Charge shall commence on the 31st calendar day after the invoice date,and continue from month to month until the delinquent balance is resolved.The Late Payment Charge shall be assessed monthly,based on the delinquent balance maintained on the account at that time.The Late Payment Charge shall be an amount equal to the outstanding delinquent balance multiplied by the applicable interest rate.The interest rate shall be 18%annually,simple interest (1.5%per month,simple interest)unless an applicable law or regulation specifies a lower rate to be charged,and that lower rate shall then apply.The Customer shall not be charged a Late Payment Charge on a delinquent balance,however,if an applicable law or regulation prohibits the imposition of such charges. In the event a Customer disputes,in good faith,the validity of any private line services charges appearing on its invoice,as specified in this tariff,the amount of these disputed charges will be excluded from the total delinquent balance while the dispute is pending.If the Company sustains the charges after investigating the dispute,the applicable Late Payment Charges shall be deemed correct and binding on the Customer.If,alternately,the Company credits the charges after investigating the dispute,the Late Payment Charges will not apply. When a local exchange company provides the billing function on behalf of the Company,the local exchange company's local exchange service late payment charge applies.Late payment charges do not apply until after the due date of the bill on which the usage charges first appear. COMPUTER NETWORK TECHNOLOGY CORPORATIONS STATE OF IDAHO PRIVATE LINE SERVICES TARIFF ISSUED:SECTON2 EFFECTIVE:ORIGINAL PAGE 26 BY:Gregory Barnum -Vice President 2.GENERAL REGULATIONS 2.6 Credit Allowances for Interruptions 2.6.1 General A credit allowance will be given when a private line service is interrupted,except as specified within this tariff.An interruption period begins when the customer reports a private line service to be interrupted and releases it for testing and repair.An interruption period ends when the private line service is operative.Only the interrupted portion of the private line service will receive a credit.If the customer reports a private line service to be inoperative but declines to release it for testing and repair,it is considered to be impaired,but not interrupted. In addition,there are specific credit allowance regulations that only apply to a particular private line service.Those regulations are specified in the section of the tariff that is applicable to the specific private line service. 2.6.2 When Credit Allowance does not Apply Credit allowance does not apply for: A.Interruptions caused by the negligence of the customer or others authorized by the customer to use the customer's service, B.Interruptions due to the failure of power,equipment,systems,or connections not provided by CNT, C.Interruptionsduring any period when the customer or user has released a private line service for maintenance or rearrangement purposes,or for the implementation of a customer order, D.Interruptions which continue because of the customer's failure to authorize replacement of any element of special construction.The period for which credit is not allowed,begins on the seventh day after the customer receives CNT's written notification of the need for such replacement.It ends on the day after receipt of the customer's written authorization for such replacement, E.interruptions during periods when the customer elects not to release the private line service for testing and/or repair, F.Interruptions caused by the failure of access service,or G.An interruption or group of interruptions,resulting from a common cause,for amounts totaling less than one dollar. H.Interruptions during any period in which CNT or its agents are not afforded access to the customer's premises.

The signaling arrangements available permit signals generated by other equipment at a location to be transmitted over a local channel service.They do not include the capability to initiate or receive those signals. The signaling arrangement to be used on a local channel service is dependent on the type of equipment connected to the local channel service,the function of the channel (e.g.,off-premises station,foreign exchange,tie trunk)and the manner in which the customer wants the signal process to operate (e.g.,ringdown,dial). 1.Loop Start Loop Signaling Loop start loop signaling is used for off-premises stations,trunk to station tie lines,and other channels which are terminated in switching equipment at one end and other terminal equipment (e.g.,in a handset)at the other end.The interface with the switching equipment is referred to as the open end and the interface with the station is referred to as the closed end. This signaling arrangement is designed to pass an open loop (idle condition)or closed loop (seized condition)from the station to the switching equipment.It will transmit dial pulse or multifrequency pulsing signals from the station to the switching equipment and dial tone and 20 Hertz ringing from the switching equipment to the station. 2.Ground Start Loop Signaling This signaling arrangement is used for channels that interface with central office switching equipment on the open end and PBX on the closed end to provide a PBX to central office trunk. In the operation of this arrangement the closed end provides a closed loop and momentary ground for the ring conductor as a seizure.The open end provides a ground on the tip and battery on the ring as a seizure.This arrangement will transmit dial tone and 20 Hertz ringing from the open end to the closed end,and will transmit dial pulses or multifrequency pulsing address signals from the closed end to the open end.
