RAD Megaplex Common logic Module v.2 Ethernet

Common Logic Module for the Megaplex 2100. The module is V.2 with a UTP management port and stores configuration and event information.

The ML-1/2 electrical copper interface and MLF-1/2 fiber optic interface modules connect Megaplex-2100/2104 to one or two E1/T1 lines. Multiple main link modules can be installed in a single chassis, giving Megaplex a capacity of up to four full E1 links or five full T1 links, for both point to point and point-to-multipoint applications. Alternatively, multiple fractional E1/T1 links can be used. The E1/T1 ring functionality can be configured in a single database, allowing an unlimited number of nodes per ring with protection speed of up to 5 seconds E1 link modules are compatible with all carrier-provided E1 services, meeting the requirements of ITU-T Recommendations G.703, G.704 and G.732. They also support CRC-4 and E bit, in compliance with G.704 recommendations. Zero suppression over the lines is HDB3. 

The MLF modules are compatible with RAD’s standalone FOM-E1/T1 fiber modem and with the fiber modules of FCD, DXC and other Megaplex systems. The internal cross-connect matrix of the ML and MLF main link modules routes voice and data channels from any I/O module installed in the chassis to any installed main link. The matrix can route voice and data traffic from any link to any other link. The non-blocking full cross connect feature enables flexible timeslot assignment and efficient utilization of E1/T1 bandwidth. It also facilitates drop&insert, bypass and broadcast multilink applications. 

Features include: One or two E1 or T1 link interfaces with built-in non-blocking DS0 cross-connect between any ML modules, Built-in LTU (E1) or CSU (T1) on copper interface ML modules, Various fiber optic interface options, with ranges of up to 100 km (62 miles), for MLF modules, Main link module redundancy, including ring redundancy.
