LED Description
LINK/ACT
z
ON means carrier signal has been received.
z Blinking means data is being received or/and transmitted.
z OFF means no carrier signal has been received.
LP/AL
z
ON means the interface is in a loopback.
z
Blinking means an AIS, LFA, or RAI alarm signal is present.
z
OFF means no loopback or alarm is present.
Note:
LFA = Loss of frame alignment; AIS = Alarm indication signal; RAI = Remote alarm indication.
Interface optical fiber
Choose an optical fiber cable appropriate to the FIC-1ATM-OC3 for installation.
Laser danger! Do not directly stare at the optical fiber connector connected with the laser, in case of the
injury that may cause to your eyes.

FIC-1POS
Introduction
FIC-1POS, the 1-port SDH/SONET interface module, 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. It supports:
z
Four types of SFP: multi-mode short-haul (1310 nm), single mode medium-haul (1310 nm), single
mode long-haul (1310 nm), and single-mode ultra-long haul (1550 nm).
