LCC interface to DS–1 interface cards

DS-1 links 0

In normal conditions, when both are active, LCC-0 connects LCA-0, and

LCC-1 connects LCA-1. The LCC-0 serves even-numbered DS-1 links (0,

2, 4) from the DS-1 interface cards. The LCC-1 serves odd-numbered DS-1

links (1, 3, 5). The previous figure shows the configuration of the LCCs.

One-to-one mapping of LCA primary ports can occur with the DS-1 links.

In this condition, all 24 DS-1 link channels come from one 32-channel

DS30A port. The system uses additional channels for control and signaling

from the host and for intraspeech and interspeech channels.

The LCC accepts eight DS30A links from the LCA of the LCC. Through

the LCC, these links provide the following:

message and speech paths to the host

connection to the RMM

link-sharing resources for each LCA
