Introduction
The 1-port channelized E3/fractional E3 interface module (FIC-1CE3) delivers these functions:
•
In E3 mode, transmitting, receiving, and processing one channel of E3 fast traffic; providing E3
traffic access.
•
In CE3 mode, providing the subscribers with N No 64 kbps low-speed access, where N is
smaller than or equal to 128.
NOTE:
E3 represents the tertiary group rate of E system in the TDM system, that is, 34.368 Mbps. Through
E23 and E12 demultiplexing, an E3 channel can be channelized into 16 E1 lines, each supporting
both the E1 and CE1 modes. E23 means either E2-to-E3 multiplex or E3-to-E2 demultiplex, and E12
means E1-to-E2 multiplex or E2-to-E1 demultiplex. "E23" and "E12" discussed here represent the
demultiplex process.
