Integrated Services Digital Network (ISDN); Signalling System No.7 (SS7); Interworking between ISDN User Part (ISUP) version 2 and Digital Subscriber Signalling System No. one (DSS1) protocols; Part 4: Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma specification

Scope

The present document specifies the network Abstract Test Suite (ATS) for the interworking between ISDN [13] and
non-ISDN access and the ISDN User Part functions and protocol of Signalling System No. 7 [2] to [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 Test Suite Structure and Test Purposes (TSS&TP) related to this
ATS and partial PIXIT proforma.
