3. OPERATION

Powering Options

The unit features automatic sensing based on the current load detected on the HDSL circuit. Span powering at less than -120 Vdc allows for span powering of circuits without REGs or with one REG.

LTU Alarm Outputs

Pin B10 of the LTU edge connector interface provides a fuse alarm signal that connects -48 Vdc to this pin in the presence of a blown fuse. This indicates the card has malfunctioned and should be replaced.

Front Panel Operation Using the Total Access 3010 SCU (P/N 1181017L1)

The front panel interface consists of a 4-character alphanumeric LED display and a 3-position switch that controls the display.

The switch positions are:

Center OFF

Up MODE

Down SELECT

The switch is spring-loaded to the center (OFF) position. The display is used to report the loop margins (dB), and other operational conditions.

Faceplate Indicators

The Total Access 3010 LTU has seven faceplate LEDs, illustrated in Table 1, which indicate operational status.

The Total Access 3010 LTU plugs directly into the Total Access 3010 shelf. No installation wiring is required.
