MODULES (FXO-4/8) > STATUS > TX ABCD
Read security: 5
Transmit Signaling bits have local significance only, and represent signaling between the ATLAS 550
Controller and the voice port if the port is configured in the DIAL PLAN. The bit pattern is formatted ESF
RBS.
MODULES (FXO-4/8) > TEST
Write security: 4; Read security: 5
The TEST options initiate different types of tests and display test results.
MODULES (FXO-4/8) > TEST > PORT
Write security: 5; Read security: 5
Displays the operating port. There are 4 available interfaces on the Quad FXO Option Module and 8 on the
Octal FXO Option Module.
MODULES (FXO-4/8) > TEST > TEST 2W
Write security: 4; Read security: 5
Activates 2W (FXO) tests on a per-port basis. Options include OFF, LOOP OPEN, LOOP CLOSED, and RING
GROUND. The 2W tests will disrupt the active call on the selected FXO port. Table 4 displays the state of
the 2W conductors during each test.
Table 4. FXO 2W State Table
TEST TIP OUTPUT RING OUTPUT
Off No test active No test active
Loop Open High impedance High impedance
Loop Closed Off-hook impedance Off-hook impedance
Ring Ground High impedance R to ground
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.
Calls may be affected when activating the Tx ABCD test. This test is not valid when the
port is used in the DIAL PLAN.
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.
