Configuration Guide

Front Panel Description

STATUS

When the green indicator is On, the
unit is powered and may be
operating normally.
When the red indicator is On, there
is a fault that exceeds alarm
thresholds or another type of unit
failure.

This green indicator is On during a
mark condition on the high-speed
transmit-data line.

This green indicator is On during a
mark condition on the high-speed
receive-data line.

RTS

This green indicator is On when the
request to send signal is active.

DTR

This green indicator is On when the
data terminal ready signal is active.

FAR/LOC In the FAR position, the 4051 sends

five seconds of the V.54 loop
pattern then switches to the 511
pattern.

In the middle position, the 4051
sends five seconds of V.54
loopdown code then returns to its
normal operating mode.
In the LOC position, the 4051
performs a network latching
loopback.

Activity
Indicators

These two, small recessed
indicators are just above the
supervisory connector and show
supervisory and network manager
port activity.

SUPV

The supervisory port provides
direct terminal access to control
and monitor the 4051.

NET LOS This red indicator is On during a

loss of signal from the DDS
network.

NET OOF This amber indicator is On when

the unit detects and out of frame
condition or receives OOF codes.

TST
LOOP

This amber indicator is On when
the network interface is in any loop.

TST
BERT

This indicator is On when a 511-bit
BERT is in progress.

TST ERR This indicator is On when BERT

pattern errors are detected.
