DS/ETS 300192
Private Telecommunication Network (PTN) - Signalling protocol at the S-reference point - Circuit mode basic services
| Organization: | DS |
| Publication Date: | 7 July 1993 |
| Status: | active |
| ICS Code (Telephone networks): | 33.040.35 |
scope:
The 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. The standard is based upon ETS 300 102-1, which defines the equivalent protocol for the T and T coincident and S reference points between a user and a public ISDN.
