SIC-1E1-F
Introduction
The 1-port fractional E1 interface module (SIC-1E1-F) 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-1E1-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-1E1-F does not support the PRI mode.

LINK/ACT
• On means carrier signal has been received.
• Flashing means data is being transmitted or received.
• Off means no carrier signal has been received.
LP/AL
• On means the interface is in a loopback.
• Flashing means an AIS, LFA, or RAI alarm signal is present.
• Off means neither loopback nor alarm is present.
Note:
AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm indication
