[Megaco] Stimulus Control Protocol; Re: H.248.V5 vs H.248.STIMAL; Re: [LS to SG16 RGW stimal package ] Approved

[Albrecht.Schwarz at alcatel.de]

Just another thought when reading the package.

I know, it's farfetched, but there seems to be already a "similar" solution
defined:

There's already an H.248-based Stimulus Control Protocol:  H.323 Annex L.
Annex L incorporates Simple Endpoint Types (SET) according H.323 Annex F.
Annex F incorporates "telephones with an RJ-45 connector", i.e., POTS
terminals.

=> for that specific network scenario, and from a high-level perspective,
there are obviously overlappings (e.g., analog line, H.248 control
interface, stimulus control concept).

But I guess that the comparison of H.248.STIMAL versus H.248-based H.323
Annex L is inappropriate, mainly because
- H.323 Annex L still uses normal call establihsment procedures of H.225.0
- H.323 Annex L approach is scoping supplementary services, not basic call
setup/release
- H.248.STIMAL is scoping basic call service, PSTN supplementary service
are for instance scope of H.248.23

just an idea,
Albrecht

Hello Albrecht,

Actually the first liaison you refer to is indicating to SG16 the intention
of TISPAN WG3 to create a new package, at the time there was no agreed
package or package name.  The new liaison indicates that there is now a
package defined called stimal package and that there is an ambition to
perform a joint publication between TISPAN and ITU-T, for more details
refer to the new liaison.

I hope this answers your question.

Best regards,
JanL
