Enabling the T3/T1 Controllers
Note
For T1 CAS trunks, no ISDN switch type is configured.
Step 2
Configure the T3 controller. There are 28 T1 controllers in one T3. In this example, only the fourth
controller is configured. The
t1 4 controller
command automatically creates the logical T1 controller
1/0/0:4. The number of logical T1 controllers should match the number of TI PRI lines coming into
the T3.

Step 3
Configure the corresponding T1 controllers:

After the controllers are correctly configured, the following cards and interfaces change their state:
00:01:59: %CONTROLLER-5-UPDOWN: Controller T3 1/0/0, changed state to up
00:02:01: %CONTROLLER-5-UPDOWN: Controller T1 1/0/0:4, changed state to up
00:02:02: %DIAL12-3-MSG:

00:02:05: %ISDN-6-LAYER2DOWN: Layer 2 for Interface Se1/0/0:4:23, TEI 0 changed
to down
00:02:21: %ISDN-6-LAYER2UP: Layer 2 for Interface Se1/0/0:4:23, TEI 0 changed to up

Table 3-6 describes some of the T3 and T1-controller concepts that are applied in the previous steps.
