Integrated Services Digital Network (ISDN) - Telephony 7 kHz, videotelephony, audiographic conference and videoconference teleservices - Digital Subscriber Signalling System No. one (DSS1) protocol - Part 5: Test Suite Structure and Test Purposes (TSS&TP) specification for the network
The present document is applicable to the stage three of the telephony 7 kHz and videotelephony teleservices for the
pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications
operators at the T reference point or coincident S and T reference point (as specified in ITU-T
Recommendation I.411 [8] by means of the Digital Subscriber Signalling System No. one (DSS1) protocol.
EN 300 267-1 [3] provides the protocol specification and EN 300 267-2 [4] the Protocol Implementation Conformance
Statement (PICS) proforma specification. Stage three identifies the protocol procedures and switching functions needed
to support a telecommunications service (see ITU-T Recommendation I.130 [7]).
The present document specifies the Test Suite Structure and Test Purposes (TSS&TP) for the network side. It covers the
protocol requirements as defined in EN 300 267-1 [3] and provides test purposes for the additional generic requirements
for basic telecommunication services not defined in EN 300 403-1 [1] (EN 300 267-1 [3], clause 5), for the telephony
7 kHz teleservice (EN 300 267-1 [3], clause 6), for the videotelephony teleservice (EN 300 267-1 [3], clause 7), for the
audiographic conference teleservice (EN 300 267-1 [3], clause 8) and for the videoconference teleservice
(EN 300 267-1 [3], clause 9).
Two types of implementation are covered:
- an implementation which supports network requirements at the coincident S and T reference point;
- an implementation which supports network requirements for interworking with private ISDNs at the T reference
point.
