| 释义 | SLC-96 (Subscriber Line Carrier-96) A digital loop carrier (DLC) system introduced by Western Electric (now Alcatel-Lucent), in 1979. SLC-96 comprises 1–4 T1s, or 1 T2, from the central office (CO) to a remote neighborhood node, which serves as a remote CO line shelf and time division multiplexer (TDM mux). On the other side of the node terminate 96 voice-grade analog circuits from individual customer premises.The SLC-96 DLC thereby supports 96 voice grade, two-wire local loops over 1–4 four-wire (i.e., 4 two-pair) circuits, which results in a savings of at least 88 pairs (96 – 8 = 88) from the CO to the node. Note: For fewer than 4 T1s, not all subscriber lines can be active at once. See also carrier, DLC, four-wire circuit, local loop, node, multiplexer, TDM, two-wire circuit, and voice grade. |
