Connecting to the DS3/E3 Module
S330 only Connect the DS3/E3 module to a DS3 repeater using the female BNC connectors.
The maximum coax run is 450 feet. The transmitter in the DS3 UNI Module
includes selectable LBO (Line Build-Out) to adjust the output signal to cable runs of
0-255 or 225-450 feet. Select the LBO during card configuration from the local
terminal or NMS. See “Configuring the DS3/E3 UNI Module”, in Chapter 4 for
details.
The DS3/E3 UNI module features the following front panel indicators, as illustrated
in Figure 27:
INS—Illuminates when the DS3/E3 card is in service.
ALM—Illuminates when an alarm is present on the DS3 card.
LOS (RED)—Powers up in the “off” state and illuminates when a LOS (Loss of
Signal) condition is detected on the incoming DS3. The LOS LED is off if a signal is
present. It reflects the LOS state of the DS3 in real time (no integration of the state
is needed).
