29.26 port pots gain Command
Syntax:
port pots gain <slot-port> <tx-gain> <rx-gain>
where
This command sets the amount of gain to apply to the signal the subscriber transmits (tx) or the
signal the subscriber receives (rx) for the specified port and/or slot.
The gain is measured in tenths of a decibel and the range can be from -200 to 200. Enter a
negative value to decrease the volume.
The following example sets slot 3’s port 5 to use a gain of 10 decibels for the signal from the
subscriber and a gain of 6 decibels for the signal going to the subscriber.
29.27 port pots impedance Command
Syntax:
port pots impedance <slot-port> <impedance>
where
This command sets the impedance level on the specified subscriber port.
29.28 port ppvc Commands
Use the port ppvc commands to configure PPVCs and add and remove member PVCs.
29.28.1 port ppvc delete Command
Syntax:
port ppvc delete <slot-port-vpi/vci>
<tx-gain>
=
This sets 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-gain>
=
This is the amount of gain (increase in volume) you want to apply to the signal
received from the SIP server and transmitted to the subscriber.

<impedance>
=
200ohm_680ohm_100nf, 220ohm_680ohm_100nf, 220ohm_820ohm_115nf,
220ohm_820ohm_120nf, 270ohm_750ohm_150nf, 300ohm_1000ohm_220nf,
370ohm_620ohm_310nf, 600ohm, 600ohm_1000nf, 900ohm, 900ohm_2160nf and DEFVAL
Note: DEFVAL impedance is set at the impedance of the country defined in the
countrycode command.
