MODULES (E&M-8) > STATUS > RX ABCD
Read security: 5
Receive 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 (E&M-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 (E&M-8) > TEST
Write security: 4; Read security: 5
These options initiate different types of tests and display test results.
MODULES (E&M-8) > TEST > PORT
Write security: 5; Read security: 5
Displays the operating port.
MODULES (E&M-8) > TEST > TEST 2W
Write security: 4; Read security: 5
Activates 2W (E&M) tests on a per-port basis. Options include OFF (no tests are active), E-LEAD OPEN, and
E-LEAD CLOSED. The 2W tests will disrupt the active call on the selected E&M port. Table 5 displays the
state of the 2W conductors during each test.
MODULES (E&M-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.
Table 5. E&M 2W State Table
TEST MODULE OUTPUT
Off E-lead follows the Rx (received) signaling bits
E-Lead Open Forces an on-hook situation on the port
E-Lead Closed Forces an off-hook situation on the port
Calls may be affected when activating the Tx ABCD test. This test is not valid when the
port is used in the DIAL PLAN.
