Description

Description for this port.

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..

Receive TLP Setting

The receive TLP is the signal level to the customer premises equipment (CPE). The receive signal range is +3 dB to -9 dB.   A positive number adds gain, a negative number adds loss to the analog signal after decoding from PCM. For example, a receive TLP setting of -6 dB will generate a voice signal at -6 dB level.

Values:

A dB setting from -9 to 2, inclusive.

Default:

-6 dB

Transmit TLP Setting

The transmit TLP is the signal level from the customer premises equipment (CPE). The transmit signal range is +9 dB to -3 dB. A positive number adds loss, a negative number adds gain to the analog signal before encoding to PCM. For example, a transmit TLP setting of +3 dB will set a loss of 3 dB to generate a 0 dB PCM signal.

Values:

A dB setting from -3 to 6, inclusive.

Default:

0 dB
