MAX:/CONFIG/R2>change sdwt <value>
The option value can be selected from 1 second 30 seconds.
Dial guard time (guard)
This parameter is used to set the time from the point of sending seizure signal or
receiving seizure ack signal preceded by sending seizure signal, to the point of
DTMF tone being sent, in case of an outgoing call in DTMF signaling.
MAX:/CONFIG/R2>change guard <value>
The option value can be selected from 10 ms to 1000 ms.
Dial duration (dur)
This parameter is used to set the time to maintain DTMF tone in sending DTMF
tone in DTMF signaling.
MAX:/CONFIG/R2>change dur <value>
The option value can be selected from 10 ms to 1000 ms.
Dial interval (intv)
This parameter is used to set the inter-digit time between DTMF tones in DTMF
signaling.
MAX:/CONFIG/R2>change intv <value>
The option value can be selected from 10 ms 1000 ms.
Dial Tone Type (dtype)
This parameter is used to set dial tone type to send through voice channel after
receiving seizure signal in DTMF signaling.
MAX:/CONFIG/R2>change dtype <value>
The option value can be selected as ‘
cont
’ or ‘
dcont
’(discontinuous).
‘
cont
’ means continuous dial tone and ‘
dcont
’ indicates discontinuous tone.
Seizure Guard Time (t1)
This parameter is used to set the time needed to recognize as seizure signal.
To be recognized as seizure signal, the value of signaling bit must be maintained
and unchanged for a certain time (seizure guard time) after receiving seizure
signaling bit in CAS line signaling.
MAX:/CONFIG/R2>change t1 <value>
The option value can be selected from 0 ms to 1000 ms.
