182 Matrix ETERNITY NE System Manual
4. Select Dial Type as Tone or Pulse. Default: Tone.
You can configure the Dialing method as Pulse or Tone (with configurable Pulse Ratio and DTMF ON-OFF
period) according to the Dialing method supported by the CO network to which the CO port is connected.
5. If you selected Pulse as Dial Type, select the appropriate Pulse Dial Ratio from the following options
according to the type of Pulse Dialing Ration supported by your CO Network.
• 10PPS, 1:2
• 10PPS, 2:3
• 10PPS, 1:1
• 20PPS, 1:2
• 20PPS,2:3
• 20PPS, 1:1
Default: 10 PPS 1:2.
6. If required, you may You can increase or decrease the level of Incoming Speech (Receive Gain) on the
Trunk by changing the Rx Gain (dB) to the desired level.
7. To increase or decrease the level of Outgoing Speech (Transmit Gain) on the Trunk, change the Tx Gain
(dB) to the desired level.
8. Select the type of Answer Supervision
48
supported by your Network from the following options. Default:
Pseudo Answer.
• Pseudo Answer: It is used when no signaling is available from the PSTN. If this option is selected, the
call will be considered as matured on the expiry of the 'Pseudo Answer Supervision Timer'
(configurable; default 20 seconds), irrespective of whether or not the call actually gets matured. After
this, the Call Duration Timer starts. Finally, the system starts detecting the "Disconnect Supervision"
signal configured for the CO port.
Select this option only if there is no Answer Supervision Signal supported.
• Polarity Reversal: It is used as maturity signal when the answer signaling is given in the form of
Battery Reversal. If the battery polarity of the line is -ve for TIP and +ve for RING, when the called party
has answered the call, the CO network will reverse the battery polarity, i.e. TIP becomes +ve and Ring
-ve. After this, the Call Duration Timer is started. Finally system starts detecting the Disconnect
Supervision signal configured for the CO port.
• 12 KHz/16 KHz Pulse: When called party answers the call, the CO network generates a 12/16 KHz
metering pulse to indicate call maturity. Finally, the system will start detecting Disconnect Supervision
signal configured for the CO port.
48. It is a signal from the CO network to indicate to call maturity. Whenever you make an outgoing call from CO Trunk, the CO network
will give answer signaling when the called party answers the call.
This feature is particularly useful if you want to use “Call Cost Calculation (CCC)” to enable accurate billing. When the signal is
received, the billing will start and in the absence of this signal, the call will not be billed, ensuring that unanswered and unsuccess-
ful call attempts are not billed.
