Would like to know if inter-register signaling (such as R2-compelled, R2-non-compelled) necessary for a E1R2 configuration?
I would like to integrate Cisco 2811 with NEC Neax 2000 using E1R2.
It will be necessary, yes. There is information passed with the inter-register signaling that is required for call setup.
Here's a good document on E1 R2 theory:
Also there's the little problem that the Cisco IOS CLI requires the inter-register signaling type when you define the ds0-group.
Router(config-controller)#ds0-group 1 timeslots 1-15 type r2-digital ?
dtmf DTMF tone signaling
r2-compelled R2 Compelled Register Signaling
r2-non-compelled R2 Non Compelled Register Signaling
r2-semi-compelled R2 Semi Compelled Register Signaling

Thanks for the quick reply. Hope you don't mind me to ask another question,
Do you have any experience if two-stage dialing is supported over E1 R2 interface?
