Parameter Description
Max. Flash-Hook Detection Period
[msec]
[FlashHookPeriod]
Defines the hook-flash period (in msec) for both analog and IP
sides (per device).
The valid range is 25 to 3,000. The default value is 700.
For the IP side, it defines the hook-flash period that is
reported to the IP.

For the analog side, it defines the following:
FXS interfaces:
a) Maximum hook-flash detection period. A longer signal is
considered an off-hook or on-hook event.

b) Hook-flash generation period upon detection of a SIP
INFO message containing a hook-flash signal.
FXO interfaces: Hook-flash generation period.

Notes:

For FXO interfaces, a constant of 100 msec must be
added to the required hook-flash period. For example, to
generate a 450 msec hook-flash, set this parameter to
550.
For this parameter to take effect, you need to reset the
device.
6.11.3 Metering Tone Parameters
The metering tone parameters are described in the table below.
Table 6-49: Metering Tone Parameters
Parameter Description

Disable = Metering tones aren't generated (default).
[1] Internal Table = Metering tones are generated according to the
internal table configured by the parameter ChargeCode.
Notes:

This parameter is applicable only to FXS interfaces.

If you select 'Internal Table', you must configure the 'Charge Codes
Table' (refer to ''Configuring the Charge Codes Table''
116
on page
).
Metering Tone Type Defines the metering tone (12 or 16 kHz) that is generated by FXS
interfaces.
[MeteringType]

[0]

12 kHz = 12-kHz metering tone (default).
[1] 16 kHz = 16-kHz metering tone.
Notes:

A suitable (12 or 16 KHz) FXS Coefficient file must be used for FXS
interfaces.

For this parameter to take effect, a device reset is required.
