ITP/TP Ports

This chapter describes the properties of ITP and the TP ports.
4.1.1

ITP Ports

In the ITP variant of the OSM/ESM, the DTEs are attached via sub-D female
connectors. The casings of the connectors are electrically connected to the casing
of the OSM. A screw locking mechanism holds the connectors firmly in place.

connected via RJ-45 jacks with MDI-X assignment (Medium Dependent Interface
Crossover).
