Common use of Unbundled Sub-Loop Concentration (USLC) Clause in Contracts

Unbundled Sub-Loop Concentration (USLC). 2.8.6.1 Where facilities permit, Talk America may concentrate its sub-loops onto multiple DS1s back to the BellSouth Central Office. 2.8.6.2 USLC, using the Lucent Series 5 equipment, will be offered in two system options. System A will allow up to 96 of Talk America’s sub-loops to be concentrated onto two or more DS1s. System B will allow an additional 96 of Talk America’s sub- loops to be concentrated onto two or more additional DS1s. One System A may be supplemented with one System B and they both must be physically located in a single Series 5 dual channel bank. A minimum of two DS1s is required for each system (i.e., System A requires two DS1s and System B would require an additional two DS1s or four in total). The DS1 level facility that connects the Remote Terminal site with the serving wire center is known as a Feeder Interface. All DS1 Feeder Interfaces will terminate to Talk America’s demarcation point associated with Talk America’s collocation space within the SWC that serves the remote terminal (RT). USLC service is offered with or without concentration and with or without a protection DS1. 2.8.6.3 Talk America is required to deliver its sub-loops to its own cross-box, RT, or other similar device and deliver a single cable to the BellSouth RT. This cable shall be connected, by a BellSouth technician, to a cross-connect panel within the BellSouth RT/cross-box and shall allow Talk America’s sub-loops to be placed on the USLC and transported to Talk America’s collocation space at a DS1 level.
