MODULES (FXO-4/8) > TEST > TX ABCD
Write security: 4; Read security: 5
Forces the Transmit Robbed Bit Signaling (Tx RBS) to a specified value. Values include OFF, 0000, 0101,
1010, or 1111.
MODULES (FXO-4/8) > TEST > 1KHZ TONE
Write security: 3; Read security: 5
Sends a 1kHz tone into the following locations, based on test selection: NEAR sends the tone out the 2W
FXO port, while FAR sends the tone into the digital PCM stream of the ATLAS 550 controller. These tests
are useful for verifying a voice path.
MODULES (FXO-4/8) > TEST > LOOPBACK
Write security: 3; Read security: 5
Activates loopback tests on a per-port basis.
MODULES (FXO-4/8) > CONFIG
Write security: 3; Read security: 5
All of the following configurable parameters apply to the individual FXO ports.
MODULES (FXO-4/8) > CONFIG > PRT
Read security: 5
Displays the port number. There are 4 available interfaces on the Quad FXO Option Module and 8 on the
Octal FXO Option Module.
MODULES (FXO-4/8) > CONFIG > PORT NAME
Write security: 3; Read security: 5
Accepts any alpha-numeric name up to 16 characters long, to uniquely identify each port on the FXO
Calls may be affected when activating the Tx ABCD test. This test is not valid when the
port is used in the DIAL PLAN.
OFF Normal operation.
ANALOG Loops the 2W test on itself.
DIGITAL Loops digital data entering the FXO from the ATLAS controller on
itself.
BOTH Processes both analog and digital loopback tests.
Loopback tests disrupt the call in progress on the selected FXO port.
