Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) - H.248 Profile for controlling Access and Residential Gateways

The WI will create a new version of the AGW profile. The scope of the new version is to cleanup omissions, flaws and provide clarifications on issues that have arisen due to operational experience to version 1 of the profile. An example of such a flaw/clarification is to better describe how ISDN p-type frames and f-type frames from different interfaces at the AGW to an packet handler interface can be distinguished and transported reliable. Additionally the profile should adopt the H.248.1 version 3 profile template that all the other TISPAN profiles.

1 Scope

The present document defines a profile of the Gateway Control Protocol (H.248.1), for controlling access and

residential gateways connecting analog lines and ISDN primary and basic accesses, in order to emulate PSTN/ISDN

services over IP.
1.1 Differences between H.248 ARGW Profiles Version 1 and
Version 2
The differences between both H.248 profile versions are detailed in annex A.
Summary list of differences:
1) Package usage details (see clause 5.14.2).

2) IUA/SCTP encapsulation for Q.921 p-/f-type frames in IP domain (see clause 7.3.2).

3) Additional V5 support (see clause 7.4).
4) Adaptive-rate based MGC overload control (see clause 8.1.2).
5) Real time statistics reporting (see clause 8.4).

For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,

the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the

reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the

method of access to the referenced document and the full network address, with the same punctuation and use of upper

1 Scope

The present document defines a profile of the Gateway Control Protocol (H.248.1), for controlling access and

residential gateways connecting analog lines and ISDN primary and basic accesses, in order to emulate PSTN/ISDN

services over IP.
1.1 Differences between H.248 ARGW Profiles Version 1 and
Version 2
The differences between both H.248 profile versions are detailed in annex A.
Summary list of differences:
1) Package usage details (see clause 5.14.2).

2) IUA/SCTP encapsulation for Q.921 p-/f-type frames in IP domain (see clause 7.3.2).

3) Additional V5 support (see clause 7.4).
4) Adaptive-rate based MGC overload control (see clause 8.1.2).
5) Real time statistics reporting (see clause 8.4).
2 References

non-specific.
• For a specific reference, subsequent revisions do not apply.

• Non-specific reference may be made only to a complete document or a part thereof and only in the following

cases:

1 Scope

The present document defines a profile of the Gateway Control Protocol (H.248.1), for controlling access and

residential gateways connecting analog lines and ISDN primary and basic accesses, in order to emulate PSTN/ISDN

services over IP.
1.1 Differences between H.248 ARGW Profiles Version 1 and
Version 2
The differences between both H.248 profile versions are detailed in annex A.
Summary list of differences:
1) Package usage details (see clause 5.14.2).

2) IUA/SCTP encapsulation for Q.921 p-/f-type frames in IP domain (see clause 7.3.2).

3) Additional V5 support (see clause 7.4).
4) Adaptive-rate based MGC overload control (see clause 8.1.2).
5) Real time statistics reporting (see clause 8.4).
2 References

References are either specific (identified by date of publication and/or edition number or version number) or

non-specific.
• For a specific reference, subsequent revisions do not apply.

• Non-specific reference may be made only to a complete document or a part thereof and only in the following

cases:

- if it is accepted that it will be possible to use all future changes of the referenced document for the purposes

of the referring document;
- for informative references.

Referenced documents which are not found to be publicly available in the expected location might be found at

http://docbox.etsi.org/Reference.

For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,

the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the

reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the

method of access to the referenced document and the full network address, with the same punctuation and use of upper

case and lower case letters.

NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee

their long term validity.
2.1 Normative references

The following referenced documents are indispensable for the application of the present document. For dated

references, only the edition cited applies. For non-specific references, the latest edition of the referenced document

(including any amendments) applies.
