SIC-1E1-F

Introduction

1-port fractional E1 interface module (SIC-1E1-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 FE1 operating mode supported by the SIC-1E1-F module allows only one bundle. The time slots can

only be bundled into one n x 64 kbps channel, where n is in the range of 1 to 31.

The SIC-1E1-F does not support the PRI mode.
