MIM-1CPOS Module 139
MIM-1CPOS Module
Introduction 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:
Four types of hot-swappable SFP optical interface modules for your choice:
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
