CHAPTER28 Configuring Supplementary Services
Mediant 1000 Gateway & E-SBC | User's Manual
For more information on the proprietary methods, see the PayPhoneMeteringMode parameter in
Metering Tone Parameters.
➢ To configure AOC:
1. Make sure that the PSTN protocol for the trunk line is configured to Euro ISDN and network
side.
2. Make sure that the date and time of the device is correct. For accuracy, it is recommended to
use an NTP server to obtain the date and time. For more information, see Date and Time.
3. Configure the required AOC method:
● Device Generation of AOC to Tel:
i. Open the Supplementary Services page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > Supplementary Services Settings),
and then configure the 'Generate Metering Tones' parameter
(PayPhoneMeteringMode) to Charge Code Table.
ii. In the Charge Codes table, configure Charge Codes (see Configuring Charge Codes).
iii. In the Tel-to-IP Routing table, assign the Charge Code index to the relevant Tel-to-IP
routing rule (see Configuring Tel-to-IP Routing Rules).
● AOC in Tel-to-IP Direction: Open the Supplementary Services Settings page, and then
configure the 'AoC Support' parameter to Enable to send AOC to IP.
● AOC in IP-to-Tel Direction: Open the Supplementary Services page, and then configure
the 'Generate Metering Tones' parameter (PayPhoneMeteringMode) to one of the
following: SIP Interval Provided, SIP RAW Data Provided, SIP RAW Data
Incremental Provided, or SIP-to-Tel Interworking.
Configuring Charge Codes
The Charge Codes table lets you configure metering tones:
■ Analog interfaces: Metering tones that the device generates to the Tel side on its FXS
interfaces.
■ Digital interfaces: Advice of Charge (AOC) services for Euro ISDN trunks (see Advice of
Charge Services for Euro ISDN).
You can configure up to 25 different Charge Codes, where each table row represents a Charge
Code. Each Charge Code can include up to four different time periods in a day (24 hours). 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 (units) upon call
connection (answer), and from that point on, it generates a pulse (unit) for each interval. If a call
starts at a certain time period and crosses to the next period, the information of the next time period
is used. For Advice of Charge services (digital interfaces only), you can also configure the currency
type in the sent AOC messages as well as a multiplier that is applied to the charged units.
To assign Charge Codes to Tel-to-IP calls, use the Tel-to-IP Routing table.
