Connecting to the DS3/E3 Module
Connect the DS3/E3 module to a DS3 repeater using the female BNC connectors.
S330 only
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. For details, see "Configuring the DS3/E3 UNI Module" in
Chapter 4.
DS3/E3 LEDs In addition to the common LEDs described earlier in this chapter,
the following LEDs indicate the status of the DS3/E3 UNI port. (See Figure 33.)
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 state of the DS3 in real time.
LOF (RED) — Powers up in the "off" state and illuminates when a LOF (Loss of
Frame) condition is detected on the incoming DS3. The LOF LED is off when the
signal is in frame. It reflects the state of the DS3 in real time.
LOCD (RED) — Powers up in the "off" state and illuminates when a LOCD
(Loss of Cell Delineation) condition is detected on the incoming DS3 under HEC
(Header Error Control) framing. The LOCD LED is off when delineations are
obtained. It reflects the state of the DS3 in real time.
