You need to know the type of circuit you are tuning up along with appropriate configuration settings in order to successfully make it work. For example if this is a PRI circuit you need to find out ISDN switch-type (many different variants base on geography), line code, framing, etc. And then follow the great directions from Adul (+5 points).

Dont forget to also define clocking for the PRI, and specify card type:

card type e1 0 0

network-clock-participate wic 0

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

Hi Pankaj,

here is an example with are few commands that you need to configure. (this is an example if you use  T1 cards, if you are using E1 Cards then refer the link  http://www.cisco.com/en/US/docs/ios/12_0/dial/configuration/guide/dcchant.html#wp4736 )

R1(config)# isdn switch-type     (this is global command to specify switch type)

R1(config)#controller t1 3/1    (Specify a T1 controller on a Cisco router with slot-3 here and port -1 here )

R1(config-controller)#framing esf   (Define the framing characteristics as Extended Superframe Format -ESF)

R1(config-controller)#linecode b8zs  (Define the line code as binary 8 zero substitution (B8ZS) )

R1(config-controller)#pri-group timeslots 1-3 service mgcp  (Configure ISDN PRI.)

R1(config-controller)#no shut

R1(config-controller)#exit

R1(config)#isdn switch-type         ( ni is fot T1 and net5 is for E1)

R1(config)#int s3/1:23     (Specify D channel on the serial interface for channelized T1)

R1(config-if)#isdn bind-l3 ccm-manager  (Bind it with call manager )

R1(config-if)#isdn outgoing display-ie

R1(config-if)#exit

Hope this helps
