18.6.3 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 Outbound IP Routing Table'.
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.
• The Charge Codes table can also be used to configure Advice of Charge
(AoC) services for Euro ISDN trunks (see Advice of Charge Services for
Euro ISDN on page 319).
To configure the Charge Codes:
1. Open the Charge Codes Table page (Configuration tab > VoIP menu > GW and IP
to IP submenu > Analog Gateway submenu > Charge Codes). Alternatively, you can
access this page from the Metering Tones page (see 'Configuring Metering Tones' on
page 321).

2. Define up to 25 different charge codes (each charge code is defined per row). Each
charge code can include up to four different time periods in a day (24 hours). Each
time period is composed of the following:
• The end of the time period (in a 24 rounded-hour's format).
• The time interval between pulses (in tenths of a second).
• The number of pulses sent on answer.
The first time period always starts at midnight (00). It is mandatory that the last time
period of each rule ends at midnight (00). This prevents undefined time frames in a
day. The device selects the time period by comparing the device 's current time to the
end time of each time period of the selected Charge Code. The device generates the
Number of Pulses on Answer once the call is connected and from that point on, it
generates a pulse each Pulse Interval. If a call starts at a certain time period and
crosses to the next, the information of the next time period is used.
