CPOS (SDH/SONET) interface module

• FIC-1CPOS

FIC-1CPOS

Introduction

The 1-port channelized SDH/SONET interface module (FIC-1CPOS) provides one

STM-1/OC3-compliant multi-channel interface and supports communication speeds up to 155.52 Mbps.

The FIC-1CPOS supports the switchover of E1 and T1 interface modes.

The FIC-1CPOS communicates with the CPU through the PCI interface to receive and transmit data on the

STM-1 channelized POS interface. It supports:

• Four types of hot swappable SFP optical interface modules: 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).

• Clear channel (unframed) E1 or T1

• Fractional (framed) E1 or T1

• Up to 256 64 kbps logical channels
