7.4 Dedicated Transmission Service DTS transport includes dedicated transmission service between two or more POPs. The connection between the locations receiving this service is permanently established unless a service request for modification, move, or disconnect is received. This service can be used for any application, such as voice, data, video, and multimedia. DTS provides facilities for duplex, i.e. bi-directional, service; accordingly, DTS is priced without regard for direction of carried traffic. DTS pricing is based on the use of three general pricing components: (1) originating access, (2) network transport, and (3) terminating access. DTS features and UNIs are priced separately. When DTS service is provided between two domestic SDPs that are both served by the same designated connecting Sprint POP (for the same DTS service type) and a user agency requires direct SDP to SDP routing that is not connected through Sprint's designated connecting POP, Sprint will provide a price quote upon request and, if ordered, provide such service on an individual case basis. In the case of multipoint DTS connections, a least cost routing algorithm will be used to calculate the number of, and identities of, the transport and/or access links used. Each sub-category is discussed in the following sections. X X.

7.4.1 DTS Access DTS service is provisioned utilizing dedicated access facilities. The price information for dedicated access is contained in Table B.8.1.1-1, Table B.8.1.1-2, and Table B.8.1.1-3. Reference Section 7.6.1 for a description of dedicated access pricing. Pricing for non- domestic dedicated access will be provided on a pass through basis. Pricing sub-components for UNIs also apply when dedicated access is utilized for DTS. Where dedicated access facilities are used to connect the SDP to Sprint’s designated connecting POP; the dedicated access prices in Table B.8.1.1-1 or Table B.8.1.1-3 shall apply. The steps required to price a DTS basic access service are outlined below: (1) Determine the appropriate access pricing table based on the access arrangement. The pricing tables applicable to each type of access arrangement are outlined below: Access Arrangement Pricing Table On-net Dedicated Table B.8.1.1-1, Table B.8.1.1-2, Table B.8.1.1-3 (2) Determine the desired Access Type.

7.4.2 DTS Transport

Tables B.4.3-1 and B.4.3-4 contain the basic service pricing information for domestic and non-domestic circuits. The price for providing DTS domestic transport is a combination of monthly recurring plus distance-based prices. The price for providing non-domestic DTS transport will be monthly recurring. The price components used to price DTS transport depend on the location of the serving POPs.

(A)When both serving POPs are in the same domestic service region, a single price component from Table B.4.3-1 for DTS Domestic Transport will be used. The steps to calculate DTS Domestic transport are as follows:

DTS Domestic Transport (Table B.4.3-1)

(1) Determine the NPANXX of the originating and terminating locations. (2) Locate the originating and terminating NPANXX in the NPANXX to POP relationship, Table B.8.10-2. Obtain the POP ID of the designated originating and terminating POPs. (3) Obtain the Vertical and Horizontal (V&H) coordinates of the designated originating POP from TableB.8.10-1. The POP Id obtained in Step (2) is used to locate the designated originating POP. (4) Obtain the Vertical and Horizontal (V&H) coordinates of the designated terminating POP from Table B.8.10-1. The POP Id obtained in Step (2) is used to locate the designated terminating POP.

Note: The difference is always obtained by subtracting the smaller coordinate from the larger coordinate. (6) Square each difference obtained in Step (5). (7) Add the squares of the “V” difference and the “H” difference obtained in Step (6). (8) Divide the sum of the squares obtained in Step (7) by 10. Round to the next higher whole number if any fraction is obtained. (9) Obtain the square root of the result obtained in Step (8). This is the distance in miles between the two designated POPs. (Fractional miles are considered as whole miles, i.e. round up). For example: The distance in miles between Sprint’s POPs in Kansas City, MO, POP ID 2020 and Sprint’s POP in Washington, DC, POP ID 3221. V Coordinate H Coordinate Kansas City, MO 7027 4202 Washington, DC 5621 1583 Difference 1406 2619

Squared 1,976,836 + 6,859,161 = 8,835,997

8,835,997 = 883,599.7 10

Square root of 883,600 = 940 Miles

* For features that are circuit associated, not circuit-end associated, the price for the feature, when used on a non-domestic circuit, will be the price established for the non- domestic country/jurisdiction end of the circuit on a domestic location to non-domestic location circuit, and will be the price established for the originating country/jurisdiction end of the circuit on a non-domestic location to non-domestic location circuit. The user agency will designate which is the originating country/jurisdiction end of a non- domestic-to-non-domestic circuit at the time of service ordering.

** Non-domestic pricing shall be individual case basis.

*** Additional mileage is calculated as the difference between actual route miles and air miles.
