MP-1xx H.323 User’s Manual 5. Configuring the MP-1xx
Version 4.4 101 March 2005
Table 5-27: FXO Parameters (continues on pages 100 to 101)
Parameter Description
Waiting For Dial Tone
[IsWaitForDialTone]
No [0] = Don’t wait for dial tone.
Yes [1] = Wait for dial tone (default).
Used for IPMP-1xx/FXO gateways, when ‘One Stage Dialing’ is enabled.
If “wait for dial tone” is enabled, the FXO gateway dials the phone number (to the
PSTN/PBX line) only after it detects a dial tone.
Note 1: The correct dial tone parameters should be configured in the Call Progress
Tones file.
Note 2: It can take the gateway 1 to 3 seconds to detect a dial tone (according to
the dial tone configuration in the Call Progress Tones file).
If ‘Waiting For Dial Tone‘ is disabled, the FXO gateway immediately dials the phone
number after seizing the PSTN/PBX line, without ‘listening’ to dial tone.
Time to Wait before Dialing
[FXOWaitForDialTime]
Delay (in milliseconds) between the time the line is seized and dialing is begun.
The default is 1000 msec.
Note: Applicable only to MP-10x/FXO for single stage dialing, when waiting for dial
tone is disabled.
Ring Detection Timeout
[FXOBetweenRingTime]
Note: Applicable only to MP-10x/FXO gateways for TelIP calls.
The Ring Detection timeout is used differently for normal and for automatic dialing.
If automatic dialing is not used, and if Caller ID is enabled, then the FXO gateway
seizes the line after detection of the second ring signal (allowing detection of caller
ID, sent between the first and the second rings). If the second ring signal doesn’t
arrive for “Ring Detection Timeout” the gateway doesn’t initiate a call to IP.
When automatic dialing is used, the FXO gateway initiates a call to IP when ringing
signal is detected. The FXO line is seized only if the remote IP party answers the
call. If the remote party doesn’t answer the call and the ringing signal stops for “Ring
Detection Timeout”, the FXO gateway Releases the IP call.
Usually set to a value between 5 to 8.
The default is 8 seconds.
Reorder Tone Duration
[TimeForReorderTone]
Busy or Reorder tone duration (seconds) the FXO gateway plays before releasing
the line.
The valid range is 0 to 100. The default is 10 seconds.
Usually, after playing a Reorder / Busy tone for the specified duration, the FXS
gateway, starts playing an Offhook Warning tone.
Note 1: Selection of Busy or Reorder tone is performed according to the release
cause received from IP.
Note 2: Refer also to the parameter ‘CutThrough’ (described in Table
5-5).
Answer Supervision
[EnableVoiceDetection]
Yes [1] = FXO gateway sends Connect message when speech/fax/modem is
detected.
No [0] = Connect is sent immediately after the FXO gateway finishes dialing
(default).
Note 1: To activate this feature set “DSPVersionTemplateNumber” parameter to 2
or 3.
Usually this feature is used only with Fast Connect to establish voice path before
the call is answered.
Note 2: This feature is applicable only to ‘One Stage’ dialing.
Rings before Detecting Caller ID
[RingsBeforeCallerID]
Sets the number of rings before the gateway starts detection of Caller ID (FXO
only).
0 [0]= Before first ring.
1 [1]= After first ring (default).
2 [2]= After second ring.
SendMetering2IP
[Send Metering Message to IP]
No [0] = Disabled (default).
Yes [1] = FXO gateways send a metering tone Facility message to IP on
detection of 12/16 kHz metering pulse. FXS gateways generate the 12/16 kHz
metering tone on reception of a metering message.
Note: Suitable (12 kHz or 16 kHz) coeff file must be used for both FXS and FXO
gateways. The ‘MeteringType’ parameter must be defined in both FXS/FXO
gateways.
