Quidway® AR 46 Router E1 Interface Module
Overview
The E1 interface module of the AR46 router falls into channelized type (FIC-*E1) and non
channelized type (FIC-*E1-F). Where, the channelized E1 interface module includes four types:
FIC-1E1/FIC-2E1/FIC-4E1/FIC-8E1, indicating 1-port, 2-port, 4-port and 8-port channelized E1/PRI
interface modules. The non channelized E1 interface module includes FIC-4E1-F and FIC-8E1-F,
indicating 4-port and 8-port non channelized E1 interface cards. Where, E1-F indicates fractional
E1. Its main differences from the channelized E1 interface module are:
z The FE1 working mode supported by the non channelized E1 interface module can be bound
once (bound as a channel; the rate is n × 64 K, n=1-31). The channelized E1 interface module
can group the 31 channels randomly to realize binding for many times.
z The non-channelized E1 interface module does not support the PRI mode.
Specifications
The E1 interface module of the AR46 routers falls into six types and eight specifications. The
description of specifications is listed in the following table.
