Request PRI Line and Switch Configuration from a Telco Service Provider
Before configuring ISDN PRI on your Cisco router, you need to order a correctly provisioned ISDN PRI
line from your telecommunications service provider.
This process varies from provider to provider on a national and international basis. However, some
general guidelines follow:

Controller Numbering
The T1 or E1 controller numbering convention is slot/port in CLI commands. Feature card slot
numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the
motherboard. T1 or E1 feature card slots are numbered sequentially from 1 to 7. Port numbering is from
0 to 7.
The channelized T3 controller numbering convention is slot/port in CLI commands. Feature card slot
numbering starts from the motherboard and works up from left to right. Slot 0 is reserved for the
motherboard. Feature card slots are numbered sequentially from 1 to 7. Port number value is always 0.
Determine if the outgoing B channel calls are made in ascending or descending order. The Cisco IOS
software default is descending order; however, if the switch from the service providers is configured
for outgoing calls made in ascending order, the router can be configured to match the switch
configuration of the service provider.
Ask for delivery of calling line identification. Providers sometimes call this CLI, or automatic
number identification (ANI).
If the gateway will be attached to an ISDN bus (to which other ISDN devices might be attached),
ask for point-to-multipoint service (subaddressing is required) and a voice-and-data line.
