3.4.5.2.3 Metering Tones

The FXS interfaces can generate 12/16 KHz metering pulses towards the Tel side (e.g., for

connection to a payphone or private meter). Tariff pulse rate is determined according to an

internal 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.

Note: The 'Metering Tones' page is only available if the device provides FXS

interfaces (i.e., the FXS module installed) and is applicable only to Mediant

1000.

¾ To configure the Metering tones, take these 4 steps:

1. Open the 'Metering Tones' page (Configuration tab > Protocol Configuration menu

> SIP Advanced Parameters submenu > Metering Tones page item).

Figure 3-71: Metering Tones Page

2. Configure the Metering tones parameters according to the table below.

3. Click the Submit button to save your changes.

4. To save the changes to the flash memory, refer to ''Saving Configuration'' on page

265.

Note: In the 'Tel to IP Routing' table (refer to ''Tel to IP Routing Table'' on page

200), assign a charge code rule to the routing rules you require. When a new

call is established, the 'Tel to IP Routing' table is searched for the destination

IP addresses. Once a route is found, the Charge Code (configured for that

route) is used to associate the route with an entry in the 'Charge Codes' table.
