DSP Profile Select the digital signal processing profile the port uses for voice traffic. A DSP profile
contains information about the codecs (coders/decoders)
If you have not configured any profiles, only the default profile DEFVAL can be
selected. Configure DSP profiles in the Profile > VoIP DSP screen.
Data Profile Select the digital signal processing profile the port uses for data applications like fax.
A DSP profile contains information about the codecs (coders/decoders)
If you have not configured any profiles, only the default profile DEFVAL can be
selected. Configure DSP profiles in the Profile > VoIP DSP screen.
Customer Information Enter information to identify the subscriber connected to this port. You can use up to
31 printable ASCII characters (including spaces and hyphens).
TEL Enter the telephone number of the subscriber VoIP port. This is used as part of the
port’s SIP URI.
Impedance This field displays the default VoIP port AC impedance. The default impedance value
depends on the country code (configured in the
VoIP > Countrycode screen).
If you do not want to use the default impedance, select the required AC impedance of
the VoIP port from the drop-down list.
Op Mode Set the port’s VoIP operation mode.
Select DEFVAL to use SIP to connect to a server.
Select v5sip to use V5.2 to connect to a traditional class 5 POTS switch.
Polarity Reverse Turn polarity reversal on or off. Turn on polarity reversal to reverse the tip and ring
after a call is established and again after it terminates. This is used for example, as a
charging signal for some types of payphone.
Tx / Rx Gain Tx : Enter the amount of gain (increase in volume) you want to apply to the signal
received from the subscriber and transmitted to the SIP server.
Rx : Enter the amount of gain (increase in volume) you want to apply to the signal
received from the SIP server and transmitted to the subscriber.
These are measured in tenths of a decibel and the range can be from -200 to 200.
Enter a negative value to decrease the volume.
Data Tx / Rx Gain In the first field enter the amount of gain (increase in volume) to apply to the data
(fax or modem) signal received from the subscriber and transmitted to the SIP server.
In the second field enter the amount of gain (increase in volume) to apply to the data
signal received from the SIP server and transmitted to the subscriber.
The range is -200 to 200 tenths of a decibel.
A negative value decreases the volume.
Apply Click this to save your changes to the MSC’s volatile memory. The MSC loses these
changes if it is turned off or loses power, so use the
Config Save link on the
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click this to begin configuring the fields again.
