Tying a modem (or Group-Async) to a specific physical PRI?

In our lab we have a 3600 with a bank of mica modems and 2 * PRIs. We want all calls to PRI#1 to go to Group-Async1 and all calls to PRI#2 to go to Group-Async2. Is this possible and how can it be achieved? We are running 12.3 but code upgrades aren?t an issue.


The dialer pool / dialer pool-member doesn't seem to be an option. Incoming calls terminate on line 33 and then rotate in sequence to line 44 and back to 33.


Our basic config is;



!

controller E1 0/0

pri-group timeslots 1-8,16

!

controller E1 0/1

pri-group timeslots 1-8,16

!

interface Serial0/0:15 <<-- We want this to terminate on group-async 1

no ip address

isdn switch-type primary-net5

isdn incoming-voice modem

!

interface Serial0/1:15 <<-- We want this to terminate on group-async 2

no ip address

isdn switch-type primary-net5

isdn incoming-voice modem

!

interface Group-Async1

no ip address

dialer in-band

async mode dedicated

group-range 33 38

!

interface Group-Async2

no ip address

dialer in-band

async mode interactive

group-range 39 44

!

line 33 44

login local

modem InOut

transport input all

!




Any ideas?

You need to use DNIS and Modem pools. Here is an example configuration. For full details please go to the link listed below. The link is set up for CAS but it is the same for ISDN PRI.

Configuration with One Modem Pool


In this example, only one modem pool is configured with one modem:


modem-pool part1

pool-range 1

called-number 4085551345 max-conn 1

!

controller T1 0

framing esf

clock source line primary

cas-group 0 timeslots 1-24 type e&m-fgb dtmf dnis
