Travelling Class Mark (TCM) 3

The TCM feature gives the possibility to control and restrict call originator (user) of routing in private and public network. Each originator (e.g. extensions, op’s, incoming trunks) is assigned a “facility restriction level” category which is passed through the network as TCM value. In addition, each route choice defined for a given destination in the network is also assigned a TCM value. By comparing TCM levels for call originator and chosen route, it is decided whether call setup can continue or has to be rejected. To allow continued call setup, the TCM value for call originator must be higher or equal compared to chosen route.

The category not programmed means “no routing restriction, call can always pass through”.

Value: 0 - 7.
