scope:

Interworking between SS7 ISUP and IP for the purposes of call setup is described in [ATIS-1000679]. This Technical Report (TR) addresses the complementary interworking between SS7 TCAP and IP. Therefore, this TR considers the cases of:

1. An IP Application Server transaction to a circuit domain Data Base (DB), where the application information is conveyed in SS7 TCAP.

2. A circuit domain originated transaction to an IP Application Server (AS), where the application information is conveyed in the circuit domain using SS7 TCAP.

The scope of this TR includes inter-domain interoperability under normal and abnormal or error situations.

Inter-domain transport protocol interworking between SS7 MTP/SCCP and IP is described in [ATIS- 1000047].
