MIM-1CPOS
MIM-1CPOS(E)/MIM-1CPOS(T)
Introduction
The MIM-1CPOS is short for the 1-port channelized SDH/SONET interface module. C stands for
channelized, and POS for Packet over SDH/SONET. MIM-1CPOS provides one
STM-1/OC3-compliant multi-channel interface and support communication speeds up to 155.52
Mbps.
MIM-1CPOS has two models: MIM-1CPOS(E) for E1 system and MIM-1CPOS(T) for T1 system.
MIM-1CPOS is inserted in a MIM slot of a modular router and communicates with the CPU through
the PCI interface to receive and transmit data on STM-1 channelized POS interface. It supports:
•
Various types of transceiver modules.
•
Clear channel (unframed) E1 or T1
•
Fractional (framed) E1 or T1
•
Up to 256 64 kbps logical channels
