Abstract:
A transit trunk subnetwork for interconnecting a first synchronous transfer mode switching system to a plurality of other synchronous transfer mode switching systems, the transit trunk subnetwork comprising:an asynchronous transfer mode (ATM) network connected by a first communications trunk to said first synchronous transfer mode (STM) switching system and by second communications trunks to said other STM switching systems;interfaces respectively connecting said first and second trunks with said ATM network, said interfaces converting bearer traffic from STM format to ATM format, and further converting bearer traffic from ATM format to STM format; anda signal controller for interpreting signaling messages and for mapping the movement of signaling messages between said first STM switching system and said other STM switching systems, said signal controller being adapted to identify ATM addresses of said interfaces associated with said first STM switching system and said other STM switching systems.
