ABSTRACT:
A method of and system for providing selective trunk group member termination service in a network of telecommunications switches. Each trunk group at a terminating switch that requires selective trunk member termination is identified by a terminating member trunk group parameter. A data access point (DAP) that is accessible by the switches of the network to provide call routing and number translation services identifies a set of trunk group members selected for selective trunk group member termination by means of a trunk group member range parameter. When a call is received at an originating switch of the network, the originating switch queries the DAP and the DAP returns call routing information. If the call requires selective trunk member termination, the call routing information includes the trunk group member range parameter. A terminating switch determines whether or not it has received a trunk group member range parameter for a call, the switch determines whether the terminating member trunk group parameter for the trunk group to which the call is to be terminated is set to yes. If so, the terminating switch attempts to complete the call to a truck group member in the range specified by the trunk group member range parameter.
