|Publication Date:||1 April 2010|
The present document defines the control procedures for trunk gateways when PSTN/ISDN emulation and PSTN/ISDN simulation services in an NGN Network require interworking with ETSI PSTN/ISDN services in a ISUP network. Interworking with BICC networks is not included in the scope of TISPAN R2.
Existing profiles will be evaluated, in order to determine if they can be re-used, with possible modifications, or if a completely new profile is to be defined.
