INTERFACES (FXO)

View the FXO interface status and configure the FXO parameters from this menu.

INTERFACES (FXO) > CONFIG

Configure the FXO mode, line impedance, and Tandem parameters from this menu.

INTERFACES (FXO) > CONFIG > SLOT

Displays the slot number of the installed FXO Module.

INTERFACES (FXO) > CONFIG > PORT

Indicates the port on which the FXO is installed.

INTERFACES (FXO) > CONFIG > MODE

Choices are given below. Default is LOOP START.

INTERFACES (FXO) > CONFIG > TX (dB)

Sets the TX direction level points. This signal will change the volume of the voice. TX (dB) is the signal

that is transmitted out the T1, with 0 dB being the strongest. If the volume is too loud across the T1, this

number should be increased. A higher number indicates more attenuation which equals lower volume. The

value entered must be less than 10 dB. Default is

0.0 dB.

INTERFACES (FXO) > CONFIG > RX (dB)

Sets the RX direction level points. This signal will change the volume of the voice. A higher number

indicates more attenuation which equals lower volume. The value entered must be less than 10 dB. Default

0.0 dB.

This mode must match the network configuration and/or how each port is being used. Each

port on the FXO Module is independent and should be set accordingly.

LOOP START

Sets the port to use FXO loop start signaling on the T-span and loop

start supervision on the analog 2-wire interface.

GROUND START

Sets the port to use FXO ground start signaling on the T-span and

ground start supervision on the analog 2-wire interface.

DPO

Sets the port to use Dial Pulse signaling to originate dialed numbers.

MODIFIED DPT

Sets the port to use DPT signaling on the interface. In DPT mode, digits

are transmitted out the FXO interface to the user equipment. DPT mode

is one-way operation only (outbound calls only).
