PRI Configuration -Guides Needed

[fkseow]

HI I have a 3620 router with 3 PRI interfaces with 3 PRI E1lines (90 channels)installed at the HQ level.

There are 90 remote offices using BRI lines to dial in to HQ as needed.

So to configure the HQ router for PRI connections, is there any sample configuration from Cisco website for such scenerio ?

Can I configure the PRI interface at HQ to receive call from remote office and also to dial to remote offices as needed ?

Please help out.

You can find example configs at the following URL

http://www.cisco.com/pcgi-bin/Support/browse/psp_view.pl?p=Internetworking:T1T3E1E3&s=Implementation_and_Configuration#Samples_and_Tips

and you can configure the PRI both to initiate and accept calls.
