MODULES (E&M-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 E&M
VF 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 (E&M-8) > TEST > LOOPBACK
Write security: 3; Read security: 5
Activates loopback tests on a per-port basis.
MODULES (E&M-8) > CONFIG
Write security: 3; Read security: 5
All of the following configurable parameters apply to the individual E&M ports.
MODULES (E&M-8) > CONFIG > PORT
Read security: 5
Displays the port number.
MODULES (E&M-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 Octal
E&M Option Module.
MODULES (E&M-8) > CONFIG > SIG IFCE
Write security: 3; Read security: 5
Selects signaling interface operation. The module supports all E&M types (TYPE I through TYPE V), as well
as Transmission Only (TO) mode. Press-to-talk (PTT) mode is functionally identical to the E&M TYPE V
mode.
MODULES (E&M-8) > CONFIG > VF IFCE
Write security: 3; Read security: 5
Selects either 4-wire or 2-wire output at the VF interface. The range includes +6 dB (loudest) to -12 dB
(softest).
OFF Normal operation.
ANALOG Loops the 2W test on itself.
DIGITAL Loops digital data entering the E&M from the ATLAS controller on itself.
Loopback tests disrupt the call in progress on the selected E&M port.
