Subject: [Megaco] data call using NAS pkg via a BroadBand Access Server

Hi all,

Here is my question again, need some help....

Looking at the draft of the NAS pkg I dont understand  why
it says that the user requests outgoing service is outside
the scope of the document (See 8.5 procedures).

Initially when the user calls a ISP (Internet Service Provider)
the MG does not know that it is a data call.
The MGC must inform the MG that it is a data call . How?

And  inform of  the IP of the BroadBand Access server of that ISP.
How does the MG receive the IP address of the BAS?
(I guess this is the third case of an outgoing NAS Call).

Then the MG will act accordingly ( e.g. the modem may need a special
configuration ) and pass the PPP packets of the user to the broadband
access server for
the authentication  (transparently to the MG).
From this moment  all data packets will  be sent to the Broadband server

The MG usually does not know of ISP numbers or broadband access
server. It is the MGC which has all the information. In the worst case
the MGC will enroute the traffic as a normal call.

I think this is a common scenario...
Am I missing something ?

Thanks
Fernando
