ADTRAN 1200305L1 Modules E&M-8 Test 1KHZ Tone, Modules E&M-8 Config VF Ifce, Normal operation

ATLAS 550 System Manual Section 4, User Interface Guide

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.

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.

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).
