Description

Specifies the service description and control aspects for three basic circuit-mode bearer services which may be supported by a private integrated services network. It is one of a series of Standards applicable to private integrated services networking. It is identical with and reproduced from ISO/IEC 11574:1994.

Scope

This International Standard specifies the service description and control aspects, including functional capabilities and information flows, of standardised circuit-mode bearer services which may be supported by a Private Integrated Services Network (PISN).
This International Standard includes the following basic services:
Circuit-mode 64 kbit/s unrestricted 8 kHz structured bearer service category;
Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for speech information transfer;
Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for 3,1 kHz audio information transfer.
A PISN shall support at least one of the above three bearer services to conform with this International Standard.
The scope of this International Standard does not include:
the negotiation of service at call establishment time,
the change of service during a call, and
unidirectional services.
This International Standard includes optional procedures for the provision of functions equivalent to the following public ISDN supplement services: Sub-address and Multiple Subscriber Number.
NOTES
1. Supplementary services and other bearer services which can be used in conjunction with 64 kbits/s circuit switched bearer services specified in this International Standard are dealt with in other International Standards.
2. Service specifications are based on information concerning the corresponding public ISDN service available at time of publication of this International Standard.
3 ITU-T treat Subaddressing and Multiple Subscriber Number as supplementary services.
4. The use of the Direct Dial In supplementary service of a public ISDN for calls incoming to a PISN from a public ISDN is regarded as part of the basic services in a PISN.
5. The use of the Calling Line Identification Presentation and Connected Line Identification Presentations supplementary services of a public ISDN for obtaining the
Originating Number or the Connected Number of a call from or to a public ISDN is regarded as part of the basic services in a PISN.
6. The provision (either explicitly or implicitly) by the user to the network, of its own number (Originating Number or Connected Number), and the provision of an Originating Number or a Connected Number by a PISN to another network is a part of the basic services in a PISN and not a part of the Calling Line Identification Presentation and Connected Line Identification Presentation supplementary services. Those supplementary services are concerned only with the presentation of the number from the network to the served PISN user.
