2.29 PCT

This chapter provides the brief description for Point code and CIC Translation (PCT) Feature.

The feature enables vSTP to change the DPC or OPC and or CIC of a MTP routed message. This gives vSTP the capability to emulate a point code using other nodes in its network. This feature provides a table in which translations between an emulated point code and real point codes can be defined.

Other network nodes can send traffic to the emulated PC (EPC) and receive traffic from the EPC without knowing that the real PC that is emulating the EPC. This way the Real PC can be changed transparently from the rest of the network. The rest of the network can continue sending messages to the EPC.

The PCT feature can also be used to modify the CIC of ISUP messages. Translations can be defined between Emulated CIC range and Real CIC range.
