SIC-2E1-F
Introduction
The 2-port fractional E1 interface module (fractional) provides the following features:
• 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-2E1-F module allows only one bundle. The time slots
can only be bundled into one n × 64 kbps channel, where n is in the range of 1 to 31.
The SIC-2E1-F does not support the PRI mode.
