FIC-1POS
Introduction
The 1-port SDH/SONET interface module (FIC-1POS) supports interface rates up to 155.52 Mbps
(STM-1/OC-3).
The FIC-1POS uses the protocols such as PPP, Frame Relay and HDLC at the data link layer and IP
at the network layer. It allows direct transmission of packets over SONET/SDH. The FIC-1POS
supports multiple transceiver modules.

LINK/ACT
• On means carrier signal has been received.
• Flashing means data is being received or/and transmitted.
• 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 no loopback or alarm is present.
Note:
AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm indication
