Mediant 1000 Gateway & E-SBC | User's Manual
● The CAS state machine can only be configured using the Web-based management
tool.
● Don't modify the default values unless you fully understand the implications of the
changes and know the default values. Every change affects the configuration of the
state machine parameters and the call process related to the trunk you are using
with this state machine.
● You can modify CAS state machine parameters only if the following conditions are
met:
✔ Trunks are inactive (stopped), i.e., the 'Related Trunks' field displays the trunk
number in green.
✔ State machine is not in use or is in reset, or when it is not related to any trunk.
If it is related to a trunk, you must delete the trunk or de-activate (Stop) the
trunk.
● Field values displaying "-1" indicate CAS default values. In other words, CAS state
machine values are used.
● The modification of the CAS state machine occurs at the CAS application
initialization only for non-default values (-1).
● For more information on the CAS Protocol table, refer to the CAS Protocol Table
Configuration Note.
Table 23-2: CAS State Machine Parameters Description
Parameter Description
'Generate Digit On Time'
[CasStateMachineGenerateDigitOnTime]
Generates digit on-time (in msec).
The value must be a positive value. The
default is -1 (use value from CAS state
machine).
'Generate Inter Digit Time'
[CasStateMachineGenerateInterDigitTime]
Generates digit off-time (in msec).
The value must be a positive value. The
default is -1 (use value from CAS state
machine).
'DTMF Max Detection Time'
[CasStateMachineDTMFMaxOnDetectionTime]
Detects digit maximum on time (according
to DSP detection information event) in
msec units.
The value must be a positive value. The
default is -1 (use value from CAS state
machine).
'DTMF Min Detection Time'
[CasStateMachineDTMFMinOnDetectionTime]
Detects digit minimum on time (according
to DSP detection information event) in
msec units. The digit time length must be
longer than this value to receive a
detection. Any number may be used, but
the value must be less than
CasStateMachineDTMFMaxOnDetection
Time.
The value must be a positive value. The
default is -1 (use value from CAS state
machine).
