Unbundled Voice Loops (UVLs) 2.2.1 BellSouth shall make available the following UVLs:
Unbundled Voice Loop SL2 (UVL-SL2) loops may be 2-wire or 4-wire circuits, shall have remote access test points, and will be designed with a DLR provided to NuVox. SL2 circuits can be provisioned with loop start, ground start or reverse battery signaling. OC is provided as a standard feature on SL2 loops. The OC feature will allow NuVox to coordinate the installation of the loop with the disconnect of an existing customer’s service and/or number portability service. In these cases, AT&T will perform the order conversion with standard order coordination at AT&T’s discretion during normal work hours.
