[cisco-voip] ISDN 10 configuration to 2821

[H, Tim]

Hi Dave,

It's really pretty close to being the same as a T1.  Here is some info off of my IOS 15.1 2911 VGW

card type e1 0 0

network-clock-participate wic 0
network-clock-select 1 E1 0/0/0

controller E1 0/0/0
 pri-group timeslots 1-31 service mgcp



Please note that I'm using MGCP though.  CUCM takes care of the rest of the config.

Thanks,

Tim

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
