Integrated Services Digital Network (ISDN); Signalling System No.7; Interworking between ISDN User Part (ISUP) version 2 and Digital Subscriber Signalling System No. one (DSS1); Part 3: Test Suite Structure and Test Purposes (TSS&TP) specification

Scope

The present document specifies the network Test Suite Structure and Test Purposes (TSS&TP) for the interworking
between ISDN [6] and non-ISDN access and the ISDN User Part functions and protocol of Signalling System
No. 7 [2] - [5]. The interworking between the above signalling protocols is described in EN 300 899-1 [1] and occurs in
an exchange with ISDN local exchange functionality and is specified in the context of a typical call in a pure ISDN or
mixed ISDN/non-ISDN environment. The non-ISDN access defined in the present document means the analogue line
access. The present document applies only to exchanges having implemented the ISUP V2 protocol specification.
A further part of the present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation
eXtra Information for Testing (PIXIT) proforma based on the present document.
