Task 3. Enabling the T3/T1 Controllers
Task 3. Enabling the T3/T1 Controllers
Configure the settings for the T3/T1 controllers. They must match the telcos settings on the telephone
switch. Mismatched settings cause problems; sometimes these problems are not detected for a long time.
Figure 2-4 displays the logical controller components inside a Cisco AS5800. The figure shows that a
T3 trunk card requires T1 and T3 controller configuration settings. In the figure, only the fourth
controller is configured. There are a total of 28 T1 controllers to configure.
Figure 2-4 Matching Controller Settings
Step 1 Define the ISDN PRI switch type. In the example, the T1 trunks are not using channel associated
signaling (CAS).

There are two ways to define the switch type:
Under the individual serial-D channels. A different switch type can be defined for each PRI trunk.
See the Task 4. Configuring the Serial Interfaces section on page 2-31.
Globally across all PRI trunks. All trunks use the same switch type.
Note For T1 CAS trunks, no ISDN switch type is configured.
