Private Telecommunication Networks (PTN)
- Signalling Protocol at the S Reference Point - Circuit Mode
Basic Services (SSIG-BC)
3rd edition (December 1993)
This Standard defines the Layer 3 protocol for signalling for
the support of circuit-mode bearer services (used either on their
own or in support of teleservices) at an interface at the S reference
point between a Terminal Equipment (TE) and a Private Telecommunication
Network (PTN). The S reference point is defined in ENV 41004.
This Standard is based upon ETS 300 102-1, which defines the
equivalent protocol for the T and coincident T and S reference
points between a user and a public ISDN. Many of the clauses of
ETS 300 102-1 are incorporated by reference. Any reference in
the text of ETS 300 102-1 to annex D of that document are not
applicable to this Standard. Annex F contains information on terminal
interchangeability between PTNs and public ISDNs.
This Standard is applicable to basic and primary rate accesses
of PTNXs and to TEs that are intended for connection to such accesses.
The conveyance of non-standardized (e.g. manufacturer-specific)
information in messages is outside the scope of this Standard.
Annex D discusses ways in which this can be achieved.
