Introduction
The 1-port fractional E1 interface module (SIC-E1-F) supports:
•
Transmission/Receiving and handling of E1 data streams
•
CE1 (channelized E1) access
•
Remote loopback and local loopback functions, facilitating fault test and location.
The major differences between a SIC-E1-F and a SIC-EPRI are:
•
The timeslots on an interface in FE1 mode on the SIC-E1-F can be bundled to form one
interface (namely, can be bundled into one channel, and the rate of the interface is n No 64
Kbps, where n ranges from 1 to 31.); however, you may bundle timeslots of a PRI interface on
the SIC-EPRI into up to 31 channel sets.
•
The SIC-E1-F does not support the PRI mode.
