Table 5-18: FXO Parameters (continues on pages 119 to 121)
Parameter Description
Waiting For Dial Tone
[IsWaitForDialTone]
No [0] = Don’t wait for dial tone.
Yes [1] = Wait for dial tone (default).
Used for IPÆMediant 1000/FXO modules, when ‘One Stage Dialing’ is
enabled.
If ‘wait for dial tone’ is enabled, the FXO module 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 module immediately dials the
phone number after seizing the PSTN/PBX line, without ‘listening’ to dial tone.
Time to Wait before Dialing
[WaitForDialTime]
Determines the delay before the gateway starts dialing on the FXO line in the
following scenarios (applicable only to FXO modules):
1. The delay between the time the line is seized and dialing is begun, during
the establishment of an IPÆTel call.
Note: Applicable only to FXO modules for single stage dialing, when waiting
for dial tone (IsWaitForDialTone) is disabled.
2. The delay between the time when Wink is detected and dialing is begun,
during the establishment of an IPÆTel call (for DID lines, EnableDIDWink =
1).
3. For call transfer. The delay after hook-flash is generated and dialing is
begun.
The valid range (in milliseconds) is 0 to 20000 (20 seconds). The default value
is 1000 (1 second).
Ring Detection Timeout
[FXOBetweenRingTime]
Note: Applicable only to FXO modules for TelÆIP 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
module 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 module 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 module Releases the IP
call.
Usually set to a value between 5 and 8.
The default is 8 seconds.
Reorder Tone Duration
[TimeForReorderTone]
Busy or Reorder tone duration (seconds) the FXO module plays before
releasing the line.
The valid range is 0 to 100. The default is 10 seconds for digital gateways and
0 seconds for analog gateways.
Usually, after playing a Reorder / Busy tone for the specified duration, the
FXS module, 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
5-7 on
page 80).
