Marconi Communications 1HAM60783AAU Marconi SMA/System-X/MSH86 SDH transmission Optical Transmission Module

The Marconi Communications 1HAM60783AAU is documented in Marconi parts data as the LCT unit, and our supplier record adds the LTU marking. LCT stands for local craft terminal, the on site management access an engineer plugs into to commission, configure or interrogate a node without going through the central network management system. On a multiplexer that has outlived its management platform, the craft port is often the only way in, which makes this a card worth holding.

The SMA multiplexers are Marconi SDH equipment with roots in GPT and Plessey, and they are still carrying traffic on utility, rail and private networks in the UK. A shelf combines line termination units for the tributary rates in use, optical aggregate interfaces, a system controller, alarm collection and local craft access, and dual power feeds. The 1HAM and 1HAT prefixes on the part numbers separate the unit families, and the trailing letters mark the build issue.
