Disconnect Tone - Matrix Telecom SARVAM UMG System Manual

Disconnect Tone

If Call Disconnection is signalled by your CO Network in the form of Disconnect Tone, configure Disconnect Tone
parameters on the FXO Ports. You must enable Disconnect Tone Detection on the FXO Port and select the
Disconnect Tone Type.
To enable the system to detect the Disconnect Tone accurately, you must configure the Cadence (ON-OFF time)
and Frequency of the Disconnect Tone Type you selected, as supported by the CO Network. To do so,
• Click the Advanced Settings link to expand.
• Click the Disconnect Tone link.
• The Disconnect Tone Cadence Table opens.
• For each Disconnect Tone, set the following parameters:
• Set the Frequency 1 (Hz). Valid range is 300 Hz to 1400 Hz.
• Select the Operator. You may select — Modulation (*), Addition (+) or None.
If Modulation is selected, frequency 1 and frequency 2 will be used as modulation (F1* F2).
If Addition is selected, frequency 1 and frequency 2 will be used as addition (F1 + F2).
If None is selected, frequency 2 will not be applicable.
• Set the Frequency 2 (Hz) if you selected Modulation or Addition as the Operator. Frequency 2 is
applicable only when the Disconnect Tone supported by the CO network consists of Dual Frequency.
Valid range is 20 to 1400 Hz.
• In Cadence, configure the ON Time1-OFF Time1, ON Time2-OFF Time2 and ON Time3-OFF Time-3
for each Disconnect Tone. Valid range is 0000 to 9999 msec.
When the system detects disconnect tone on the FXO Port and if it matches with the Frequency and
Cadences you have set, the call will be disconnected and the FXO Port will be released.
