I have a site in Singapore currently using this service in their current phone system. We are planning to move it over to our 2821 and give them IP phones, but I need some guidance.
I have done many domestic T1 PRI connections to voice gateways, but never an E1 or ISDN 10.
I know I will need to configure the controller E1, but what are the specifics for the timeslots? (Guessing: pri-group timeslots 1-10)?
Along with that, do you know what the D channel is? I have seen ISDN 30 configurations in Australia, using pri-group timeslots 1-31, and that uses channel 15 for the D channel.
Thanks

The D channel is used for signaling and is always channel 24 on a PRI and 16 on an E1.
Your guess on the configuration is correct. Also note that MGCP is not supported on a fractional PRI. H323 and SIP will be just fine.

you have to use h.323 gateway and then configure controller e1 with line code, framing and pri group time slots1-10
then see that gateway is working for calls over pri e1
but for this part use as a h.323 not as mgcp/
