3. Silence Sample:
Default value is 900 = 4500ms
pstn -silence “value”
This is to set silence time length for LAN Phone to determine if there is
no more PSTN incoming call. When LAN Phone has PSTN incoming call,
and PSTN user cancel this call, after LAN Phone detect 900 times (4500ms)
without Ring signal, on LCD will stop displaying “PSTN IMCOMING” and
return to standby mode.
If user set this value too short, PSTN related messages displayed on
LCD will be not smoothly, if user set this value too long, LAN Phone will
took more time to return standby mode.
We suggest user to set:
“
value = silence time(ms)
÷
5 +100 (to 200), or detected value +100
(to 200)
”. (Please refer to Part II for detail debug command of detected
silence value)
4. Auto Detect Signal:
Default value is ON.
pstn -autodet “0/1”
(0:OFF/1:ON)
This is to enable or disable auto detection function. If this function is
enabled, LAN Phone will auto detect PSTN signal type while initializing. We
strongly suggest user to enable this function.
5. Silence Signal:
LAN Phone will detect Hardware type while initializing.
Default value depends on different version of Hardware.
pstn -signal
(0:Lo/1:Hi)
For Hardware version below 1.4, please set it as Hi, for Hardware
version 1.4 or above, please set it as Lo. If user cannot be sure about the
Hardware version, please don’t set this value since LAN Phone will auto
detect PSTN signal if item 4 is enabled.
6. Initial Detect Time:
Default value is 800= 4000ms
pstn -times “value”
This is to set the length of auto-detection time when LAN Phone is
initializing. If user set this value too short, there may be not enough time for
LAN Phone to detect correct Hardware type, if user set this value too long,
it will increase initializing time of LAN Phone.
We suggest user to set:
“
value = (Ring time (ms)+ Silence time (ms))
×
2
÷
3
”
