DXX node

A node in the DXX system.

DXX support

DXX support is O&M functions in RBS
2000 intended for DXX. DXX support is a
portion of the functionality in a DXX
transport module.

A DXX node suitable to fit in the RBS
2000 cabinet.

NMS

The Network management system in

TN O&M

Centrally located management system for
transport networks and transmission
equipments in general, such as digital
cross connectors, line terminals,
