1

Status: The green LED lights when the unit is powered and operation is normal. The red LED lights if an alarm
exceeding thresholds is detected or for other unit failure.

2

TD: This green LED lights during a mark condition on the high-speed transmit data line.

3

RD: This green LED lights during a mark condition on the high-speed receive data line.

4

RTS: This green LED lights when the request-to-send signal is active.

5

CTS: This green LED lights when the clear-to-send signal is active.

6

DCD: This green LED lights when the data-carrier-detect signal is active.

7

DTR: This green LED lights when the data-terminal-ready signal is active.

8

DSR: This green LED lights when the data-set-ready signal is active.

9

Test Switch: This switch (FAR/LOC) is used for local testing. When in the FAR position, the unit sends five seconds
of the V.54 loop pattern, then switches to the 511 pattern. When transmitting a test pattern, the TEST LED is lit con-
tinuously. The ERR LED lights for one second when a bit error or sync loss on the returned data is detected. After the
FAR test has been completed, the ERR LED is Off for “passed” or On for “failed.” When in the center position, the
unit sends five seconds of V.54 loopdown code and then returns to its normal operating mode. When in the LOC posi-
tion, the unit performs a network LLB and the LOOP LEDs light.

10

Activity Indicators: This two small, recessed LEDs indicate supervisory and network manager port activity.

11

SUPV: This supervisory jack provides direct terminal access for controlling the unit. Refer to the pinout table below.

12

DBU Active: This yellow LED lights when the dial backup is active. It blinks when a dial backup connection is being
established.

13

DBU: This 10-pin jack provides a sync or async interface for external dial backup equipment and also provides a con-
nection to the internal DBU, when installed.

14

LOS: This LED lights with a loss of signal from the DDS network.

15

OOS: This LED lights when an out-of-service code is detected.

16

LOOP: This LED lights continuously when the network interface is in a line loopback.

17

TST: This LED lights continuously whenever the BERT pattern generator is active, including during LOOP,
UNLOOP, and FAR test.

18

ERR: This LED lights when BERT pattern errors are detected. At the end of a FAR test, it indicates the results of the
test as long as the FAR/LOC switch remains in the FAR postion.
