Chapter 1 General Troubleshooting

Verify Wiring from the ONS 15310-MA Shelf and DSX Wiring Panel

1.7.2.3 View and Troubleshoot Manual Test Results

The handheld receiver screen displays the test result for one DSX port and its DSX wiring, as shown in

Table 1-1. Each port is uniquely identified and reported. If a test signal generated from the TST-DSX

card is properly detected, the handheld receiver decodes the signal and the screen displays the port type

and number and gives an OK indication. Detected errors also appear on the handheld receiver screen.

Test results are not stored in the handheld receiver memory during Manual mode.

Much like a voltmeter, the handheld receiver displays what it sees. The handheld receiver reports a

“good” port signal whenever it detects a properly encoded signal at its input; it has no knowledge of any

labels at the DSX panel. For example, if the wires of a good signal for port A:12 are wrongly cross-wired

to the DSX port labeled B:84, the handheld receiver only reports what it sees: port A:12 is “good.”

While the handheld receiver is in the manual mode, the EXIT TEST or ENTER/ACCEPT keys have

no effect.

Table 1-1 Messages and Probable Indications

General

Indication Definition and Probable Cause

Specific Sample

Message Definition and Probable Cause

OK The handheld receiver detects a valid signal

from the TST-DSX card, indicating the wiring

is correct.

INP DS1 B:42 OK Input B side, port 42 for DS-1 is

detected and tests good.

OPEN/NC There is no signal at the input to the handheld

receiver. When the handheld receiver is first

powered up and before any patch cord is

inserted into the unit, the Open/NC message is

given. This message also appears if a wire is

broken from the shelf to the DSX or if a “split

pair” error is made where, for example, a

“TIP” of one port and a “RING” of another

port are both wired to the same DSX port

appearance. Also, if the TST- DSX is not

powered or not inserted into the shelf, no

signals are generated.

DS1 OPEN/NC There is no signal at the input to the

handheld receiver.

I, IN or INP An input port. A DS I or DS-3 service signal,

if present, would flow from the DSX to the

shelf.

INP DS1 B:42 OK Input B side, port 42 for DS-1 is

detected and tests good.

O or OUT An output port. A DS-1 or DS-3 service signal,

if present, would flow from the shelf to the

DSX.

OUT DS1 A: 5 OK Output A side, port 5 for DS I is

detected and tests good.

SHORT The handheld receiver detects that the TIP and

RING of a DS-1 are shorted together, or the

DS-3 center conductor is shorted to its shield

or frame ground.

DS1 SHORT The Tip and Ring of a DS-1 port are

shorted together.

UNIDENT An unidentified signal is detected. DS1

UNIDENTIFIED

The signal is not valid for the

15310-MA shelf.

INR or REV For DS-1 input wires: Tip and Ring reversal. DS1 => INP

A:11 REV

DS-1 input A side, port 11 is detected,

but the tip and ring are reversed.
