Interconnection Services Issue Date: 11/03 2 BellSouth Mileage Authority For any distance measurement from/to a BellSouth Central Office, use the V&H coordinates and mileage calculation formula filed in NECA 4. NECA is updated monthly. Ensure that you are using the most current copy. For any distance measurement from/to an End User, POP, CLEC Switch, etc. (i.e. any non-BST CO), use a tool like Telcordia® Technologies’ LocateIt product that converts an address to the appropriate V&H before calculating mileage. Never use an off-the-shelf mileage PC program to calculate mileage. This information is not updated monthly like the Telcordia® product. Telcordia ® is a trademark of Telcordia Technologies

Interconnection Services Issue Date: 11/03 15 Host/Remote Mileage Calculations Common Transport mileage is measured as the sum of the mileage from the Tandem to the Host and the mileage the Host to the Remote, rather than from the Tandem directly to the Remote. The common transport mileage in the previous example would be = 40, not 20.

Interconnection Services Issue Date: 11/03 16 Glossary of Terms MOU – Minute of Usage SWA Transport - Voice frequency transmission path composed of facilities determined by BellSouth or as ordered by the customer Switched Local Channel - provides a communications path between the customer's premises and the serving wire center of that premises. BellSouth SWA Dedicated Transport, the Switched Interoffice Channel can be provisioned between the following customer designated points: (1) the customer's serving wire center (SWC) and the Telephone Company end office switch(es), (2) the SWC and a Telephone Company Facility Hub (Hub) and, (3) the SWC and an Access Tandem, (4) a Hub and an Access Tandem, (5) a Hub to an end office and, (6) a Hub to a Hub.

Interconnection Services Issue Date: 11/03 17 Glossary of Terms (cont’d) BellSouth SWA Common Transport - Switched Interoffice Channel is provisioned between the customer designated Telephone Company end office switch(es) and the Access Tandem. This includes transport between the Access Tandem and the end office, between an end office which serves as a host for a remote switching system or module (RSS or RSM) and the RSS or RSM. Switched Dedicated Interoffice Channel (SW DIOC) rate category consists of two rate elements (1) a Switched Dedicated Transport Interoffice Channel Facility, and (2) a Switched Dedicated Transport Interoffice Channel Facility Termination. Switched Interoffice Channel provides a transmission facility and the facility termination. The Facility Termination applies for each Switched Interoffice Channel terminated.

Interconnection Services Issue Date: 11/03 18 Glossary of Terms (cont’d) Switched Common Interoffice Channel (SW CIOC) is composed of Switched Common Transport facilities as determined by the Telephone Company and permits the transmission of calls or data in the originating direction and/or terminating direction depending upon the customer's order. The SW CIOC transmission charge is a per minute of use, per mile charge. Facility termination charges are assessed on a per minute of use for greater than zero miles. Access Tandem Switching charge is assessed on all originating and terminating minutes of use switched at the Access Tandem. Dedicated Tandem Trunk Port provides for termination of transport facilities at the Telephone Company tandem switch.
