Voice Profile

Port

The port assigned to this interface.

Oper Status

Indicates the operational status of this Ethernet port.

Valid values are up and down.

Admin Status

The administrative status of the interface.

Values:

Up: The interface is enabled and up, and the status of the interface should become standby or operational

Down: The interface is disabled and down, and the status of the interface should become shutdown.

Description

Port description.

Signal Type

Loop start or ground start.

Ring Frequency

The ring frequency to be used in the foreign exchange station (FXS) interface.

Ring Back

On or off. The ring back is requested if this variable is set to on.

Terminating Impedance

Specifies the terminating impedance of voice analog interfaces.

other : none of the following; arbitrary, within limits for special cases.

ohms600Real: 600 Ohms.

ohms600Complex: 600 Ohms + 2.16uF

ohms900Complex: 900 Ohms + 2.16uF.

ohmsComplex1: complex 1; Ohms || 115nF.

This impedance is primarily used in Germany.

ohmsComplex2: complex 2; 270 Ohms + 750 Ohms || 150nF.

This impedance is primarily used in the United Kingdom and Sweden.

PCM Encoding

The type of Pulse Code Modulation encoding used.

alaw:for E1

mulaw: for T1

0 dB

Receive TLP Setting

Receive Transmission Level Point (RTLP) settings control the amount gain or loss added to the incoming signal after it is decoded to analog. To increase the signal level set the RTLP setting to higher values.

 

Transmit TLP Setting

Transmit Transmission Level Point (TTLP) settings control the amount of gain or loss added to a voice signal from CPE before it is encoded to digital PCM. To increase the signal level, reduce the TTLP setting to lower value.

 

Trunk Conditioning

The trunk conditioning setting specifies whether the FXS/FXO port should send the idle pattern to the network upon declaration of a Carrier Group Alarm (CGA) on the WAN link to which the port is assigned . In most cases leave the trunk conditioning setting at its default setting (off).

Maintenance Mode

Indicates the maintenance modes of the voice interface.

off: the interface is not in maintenance mode.

DigitalLoopback: set to perform the Digital loopback test.

AnalogLoopback: set to perform the Analog loopback test.

PCM Ecoding

The type of Pulse Code Modulation encoding used.

alaw:for E1

mulaw: for T1

Receive TLP(-160..85)

Receive Transmission Level Point (RTLP) settings control the amount gain or loss added to the incoming signal after it is decoded to analog. To increase the signal level, set the RTLP setting to higher values. The default is 0 dB.

Transmit TLP(-175..70)

Transmit Transmission Level Point (TTLP) controls the amount of gain or loss added to a voice signal from CPE before it is encoded to digital PCM. To increase the signal level, reduce the TTLP setting to lower value. The default is 0dB.
