Mediant 500 E-SBC
Notes:
•
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:
1) Trunks are inactive (stopped), i.e., the 'Related Trunks' field displays the trunk
number in green.
2) 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).
•

Configuration Note .
Table 21-1: CAS State Machine Parameters Description
Parameter Description
Generate Digit On Time
[CasStateMachineGenerateDigitOnTi
me]
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
[CasStateMachineGenerateInterDigit
Time]
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
[CasStateMachineDTMFMaxOnDetect
ionTime]
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
[CasStateMachineDTMFMinOnDetect
ionTime]
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
CasStateMachineDTMFMaxOnDetectionTime.
The value must be a positive value. The default is -1 (use
value from CAS state machine).
MAX Incoming Address Digits
[CasStateMachineMaxNumOfIncomin
gAddressDigits]
Defines the limitation for the maximum address digits that
need to be collected. After reaching this number of digits,
the collection of address digits is stopped.
The value must be an integer. The default is -1 (use value
from CAS state machine).
MAX Incoming ANI Digits
[CasStateMachineMaxNumOfIncomin
gANIDigits]
Defines the limitation for the maximum ANI digits that need
to be collected. After reaching this number of digits, the
collection of ANI digits is stopped.
The value must be an integer. The default is -1 (use value
from CAS state machine).
Collet ANI In some cases, when the state machine handles the ANI
