3.3.2.8.5.2 Configuring Metering Tones
The FXS interfaces can generate 12/16 KHz metering pulses toward the Tel side (e.g., for
connection to a pay phone or private meter). Tariff pulse rate is determined according to
the device's Charge Codes table. This capability enables users to define different tariffs
according to the source/destination numbers and the time-of-day. The tariff rate includes
the time interval between the generated pulses and the number of pulses generated on
answer.
Notes:
• The 'Metering Tones' page is available only for FXS interfaces.
• Charge Code rules can be assigned to routing rules in the 'Tel to IP
Routing' (see ''Configuring Tel to IP Routing'' on page 138). When a new
call is established, the 'Tel to IP Routing' is searched for the destination
IP address. Once a route is located, the Charge Code (configured for that
route) is used to associate the route with an entry in the 'Charge Codes'
table.
¾ To configure Metering tones:
1. Open the 'Metering Tones' page (Configuration tab > VoIP menu > GW and IP to IP
submenu > Analog Gateway submenu > Metering Tones).
Figure 3-93: Metering Tones Page
2. Configure the Metering tones parameters as required. For a description of the
parameters appearing on this page, see ''Configuration Parameters Reference'' on
page 333.
3. Click the Submit button to save your
changes.
4. To save the changes to the flash memory, see ''Saving Configuration'' on page 169.
If you set the
'Generate Metering Tones' parameter to 'Internal Table', access the 'Charge
Codes Table' page by clicking the Charge Codes Table button. For a detailed
description on configuring the Charge Codes table, see ''Configuring Charge Codes Table''
on page 151.
3.3.2.8.5.3 Configuring Charge Codes
The 'Charge Codes Table' page is used to configure the metering tones (and their time
interval) that the FXS interfaces generate to the Tel side. To associate a charge code to an
outgoing Tel-to-IP call, use the 'Tel to IP Routing'.
Notes:
• The 'Charge Codes Table' page is available only for FXS interfaces.
• You can also configure the Charge Codes table using the ini file table
parameter ChargeCode.
