Huawei NE-FIC-CE3 Specifications

Quidway® NetEngine 20 Routers Channelized E3 Interface Module
Overview
E3 indicates the tertiary group rate in a TDM system, namely 34.368 Mbps. 1-channel E3 can be
channelized to 16-channel E1s after E23 (process of demultiplexing E3 to E2) and E12 (process of
demultiplexing E2 to E1). Each E1 supports E1-F and cE1 working modes.
The channelized E3 interface module of an NE20 router supports channelized and non-channelized
E3. When an E3 can be channelized, you can set whether to bind the E1 channel with the time slot.
Functions of this module are described as follows:
When working in the E3 mode, it implements the sending, receiving and processing of
1-channel E3 high-speed data stream and provides access of E3 data stream.
When working in the cE3 mode, it provides users with N (1 to 31) x 64 Kbit/s slow access
service.
At present, the NE20 router provides only one type of channelized E3 interface module, namely
1-port channelized E3 module.
