FIC-1CE3

Introduction

FIC-1CE3, the 1-port channelized E3/fractional E3 interface module, delivers these functions:

z

In E3 mode, transmitting, receiving, and processing one channel of E3 fast traffic; providing E3
traffic access.

z

In CE3 mode, providing the subscribers with N × 64 kbps low-speed access, where N is smaller
than or equal to 128.

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.
