Nortel 25UMU00750HUJ: TN-1X plug-in unit with the ATV designation.

The Nortel 25UMU00750HUJ is a plug-in unit from the Nortel TN-1X, the STM-1 add and drop multiplexer used across SDH access networks. Part numbers in the 25U 00750 series belong to that platform, and this unit carries the ATV designation.

The TN-1X is Nortel’s STM-1 add and drop multiplexer, installed widely across UK and European SDH access networks. A node is built up from a subrack of plug-in units: the subrack controller, a mixed payload manager, 2 Mbit/s and 34/45 Mbit/s tributary units, STM-1 optical and electrical tributaries, traffic access modules and a power supply. Keeping one in service means sourcing the exact unit rather than replacing the system.
