30.2 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 Outbound IP Routing
table (see ''Configuring Outbound IP Routing'' on page 405). When a new call is
established, the Outbound IP Routing table 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.
 To configure Metering tones:
1. Open the Metering Tones page (Configuration tab > VoIP menu > GW and IP to IP >
