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:
zThe 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.
zThe 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
