A method and apparatus are disclosed for completing inter-switch calls using a single large trunk group connected to ATM facilities. In a first embodiment, all non-featured inter-switch calls are routed to the ATM facilities over the single large trunk groups. In a second embodiment, all inter-switch calls are routed to the ATM facilities over the single large trunk group. A call manager associated with the signaling network and the ATM facilities controls call routing. The advantage is a significant simplification in the translation and routing tables at the switches in the telephone network, resulting in significant savings related to the maintenance of a plurality of trunks groups at each switch.
