4.1 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.
