Dear Paul, Thank you for your reply, and your correction on the new h.246 annex-e. I expect to see some interesting contributions coming your way. You also, pointed out a every informative item.

Other groups already working on the PSTN interworking with H.323 networks, which may provide the support of H.323 terminals on Class 5 Switches.

Maybe the suggestion on expanding our H.323 interworking to provide PSTN services and H.323 terminal support on a Class-5 switch has merit. But replacing a ISDN terminal or PC with a modem connection to Internet, with a H.323 IP/Class-5 gateway is deja vu. If you have more information could you please share that information with us. Which are the groups working on providing H.323 terminals on Class 5 Switches. Regards, Ed "Reddy, Paul K" wrote:

Dear Edgar,

The new annex is H.246 Annex-E not h.246 Annex-J, which is essentially a mapping of MAP (mobile application part) of GSM or ANSI-41 or PDC networks to H.225.0.

So far new parameters in H.225.0 RAS messages, we may also need to to add parameters to H.225.0 (q.931) call control.

. Please refer to Intel's proposals (APC-1671, APC-1672)at ITU-SG16 reflector (Red Bank Meeting) for more details.

Edgar Martinez's Question: Does Intel foresee the same concepts, that is using an adjunct (switched/IP) Gateway used with the legacy Class-5 switches PSTN? to support H.323 terminals on Class 5 switches?

Paul Reddy's Answer: Intel's focus is on interworking PLMNs with H.323 networks at MAP level. Other groups already working on the PSTN interworking with H.323 networks, which may provide the support of H.323 terminals on Class 5 Switches.

Dear Paul,

An offical new annex-j for h.246 has been opened, proposed by Intel. Which is Interworking H.323 terminals with the legacy GSM and ANSI wireless networks. What this is proposing is a (MSC+VLR) Gateway that provides H.323 access to the Public Land Mobile Network (PLMN). All the voice and supplementary services will still be provided by the Legacy MSCs. And the data services only by H.323. APC 1671 "H.323 with USIM and PLMN Interworking" and APC 1672 "User Mobility and Service Mobility Services for Wireless Subscribers with H.323 terminals accessing MM over IP and PLMN Networks"

Question:

Does Intel foresee the same concepts, that is using an adjunct (swithed/IP) Gateway used with the legacy Class-5 switches PSTN? to support H.323 terminals on Class 5 switches?

Thanks, Edgar Martinez
