CAS State Machines

The 'CAS State Machine Table' screen allows you to modify various timers and other basic
parameters to define the initialization of the CAS state machine without changing the state
machine itself (no compilation is needed). The change doesn't affect the state machine
itself but rather the configuration.
To modify the CAS state machine parameters, take these 6steps:
1. Open the 'CAS State Machine Table' screen (Advanced Configuration menu >
PSTN Settings > CAS State Machine).
2. Ensure that the trunk is inactive. The trunk number displayed in the 'Related Trunks'
field must be green. If it is red (indicating that the trunk is active), click the trunk
number to open the 'Trunk Settings' screen (refer to 'Trunk Settings' on page 206),
select the required Trunk number icon, and then click Stop Trunk.
3. In the 'CAS State Machine Table' screen, modify the required parameters according to
the table below.
4. Activate the trunk if required in the 'Trunk Settings' screen by clicking the trunk
number in the 'Related Trunks' field, and in the 'Trunk Settings' screen (refer to 'Trunk
Settings' on page 206), select the required Trunk number icon, and then click Apply
Trunk Settings.
5. Click Submit.
6. Reset the gateway and save your settings to the flash memory (refer to 'Resetting the
Gateway' on page 279).
