MIM-1CE3
Introduction
The 1-port channelized E3 interface module (MIM-1CE3) serves to:
•
Transmit/Receive and handle one channel of E3 fast traffic, as well as provide the accessing of
E3 traffic when working in E3 mode.
•
Provide the low-speed accessing service at the speed of n No 64 kbps, where n is smaller than
or equal to 128, when working in CE3 mode.
NOTE:
E3 represents the tertiary group rate of E system in the TDM system, that is, 34.368 Mbps. An E3
channel can be channelized into 16 E1 lines through the demultiplexing processes of E23 and E12,
each E1 line supporting both the operating modes of E1 and CE1. E23 is used to indicate either
E2-to-E3 multiplex or E3-to-E2 demultiplex, and E12 to indicate E1-to-E2 multiplex or E2-to-E1
demultiplex. "E23" and "E12" discussed here represent the demultiplex process.
