Valid Range and Description
Duration of the current disconnect pulse (in msec).
The default is 900 msec, The range is 200 to 1500 msec.
Applicable for both FXS and FXO gateways.
The FXO gateways detection range is +/-200 msec of the
parameters value + 100.
For example if CurrentDisconnectDuration = 200, the
detection range is 100 to 500 msec.
considered a current disconnect detection.
Applicable only to FXO gateways.
The valid range is 0 to 20 Volts. The default value is 4
Volts.
Determines the frequency at which the analog line voltage is
sampled (after offhook), for detection of the current disconnect
threshold.
Applicable only to FXO gateways.
The valid range is 100 to 2500 msec. The default value is
1000 msec.
0 = Caller ID is generated between the first two rings (default).
1 = The gateway attempts to find an optimized timing to generate
the Caller ID according to the selected Caller ID type. Note that
when used with distinctive ringing, the Caller ID signal does not
change the distinctive ringing timing.
Applicable only to FXS gateways.
0 = Disable RAI (Resource Available Indication) service (default).
1 = Enable RAI service.
If RAI is enabled, an SNMP acBoardCallResourcesAlarm Alarm
Trap is sent if gateway resources fall below a predefined
(configurable) threshold.
High Threshold (in percentage) that defines the gateways busy
endpoints.
The range is 0 to 100.
The default value is 90%.
When the percentage of the gateways busy endpoints exceeds the
value configured in High Threshold, the gateway sends an SNMP
acBoardCallResourcesAlarm Alarm Trap with a major Alarm
Status.
The gateways available Resources are calculated by
dividing the number of busy endpoints by the total
number of available gateway endpoints.
