in india we have E1 as a PRI follow the procedure.
Configuring Channelized E1 ISDN PRI
To configure ISDN PRI on a channelized E1 controller, use the following commands beginning in global configuration mode:
Command Purpose
Step 1
isdn switch-type switch-type
Selects a service provider switch type that accommodates PRI. (Refer to Table 17 for a list of supported switch type keywords.)
Step 2
controller e1 slot/port
or
controller e1 number
Defines the controller location in the Cisco 7200 or Cisco 7500 series router by slot and port number.
Defines the controller location in the Cisco 4000 series or the Cisco AS5200 universal access server by unit number.1
Step 3
framing crc4
Defines the framing characteristics as cyclic redundancy check 4 (CRC4).
Step 4
linecode hdb3
Defines the line code as high-density bipolar 3 (HDB3).
Step 5
pri-group [timeslots range]
Configures ISDN PRI.
.1 Controller numbers range 0 through 2 on the Cisco 4000 series and 1 to 2 on the Cisco AS5200 access server.
If you do not specify the time slots, the specified controller is configured for 30 B channels and 1 D channel. The B channel numbers range 1 to 31; channel 16 is the D channel for E1. Corresponding serial interfaces numbers range 0 to 30. In commands, the D channel is interface serial controller-number:15. For example, interface serial 0:15.
Table 17lists the keywords for the supported service provider switch types to be used in Step 1 above.
Dlink you have to configure simple dial-up connectivity with PRI.

Hi
here's what I do on central router,
set up usernames for chap authentication between central and remote sites
username xxxxxx password 0 xxxx
if you are using one of the newer E1 cards then you must add the "card-type" command to enable it.
set-up the switch-type
isdn switch-type primary-net5
then the time slots on the E1 int
controller E1 1/0
pri-group timeslots 1-31
set up the serial int
interface Serial1/0:15
no ip address
encapsulation ppp
dialer pool-member 1
isdn switch-type primary-net5
fair-queue
ppp authentication chap
ppp multilink
then the dialers for each site
interface Dialer1
description Remote_Site_1
bandwidth 64
ip address nnn.nnn.nnn.nnn 255.255.255.252
encapsulation ppp
no ip mroute-cache
dialer pool 1
dialer remote-name xxxx
dialer idle-timeout 1800
dialer string xxxxxxxxxxxxxx
dialer-group 1
compress stac
no cdp enable
ppp authentication chap
repeat the dialer commands for the other remote sites you have
if you have a dynamic routing protocol then I would passive interface the dialers and add a static pointing to the far end of the dialer point to point link.
hope this helps
please rate if so
regards

Hi,
Proposed mini. Configuration for your PRI:
!
!
!
!
username [Your Remote office] password [your remote office]
!
!
controller E1 1/2 {assuming that controller port}
framing NO-CRC4
pri-group timeslots 1-31
description @@@@@ YOUR PRI NO. @@@@@
!
!
!
!
interface Serial1/2:15 {assuming that controller port}
description @@@@@ YOUR PRI NO @@@@@
no ip address
encapsulation ppp
no logging event link-status
dialer rotary-group 1
dialer-group 1
isdn switch-type primary-net5
no cdp enable
!
!
interface Dialer1
description
ip address {your ip address}
encapsulation ppp
no logging event link-status
dialer idle-timeout 300
dialer-group 1
ppp authentication chap
Additional:
1. Create an ACL to allow your interest ISDN traffic for.
The same you can configure to your branch office using BRI port.
Thanks
