The Numbered LEDs DO NOT indicate that a GOOD
connection exists, only that a connection exists. If the
Short or Cross LEDs are fit, there is a fault in the cable.
6.6.5 Connected LeD/3Beepers/short LeD/Numbered
LeDs
lf the Connected LED lights, the Beeper emits 3 beeps,
and the Short LED lights, the cable has a fault. The
Numbered LEDs indicate the location of a short.
Note:
In the Short mode, the Numbered LEDs only indicate
the location of the shorts. The other Connections in the
cable are not indicated. If more than 3 numbered LEDs
light, there may be multiple shorts in the cable.
6.6.6 Connected LeD/2Beepers/Cross LeD/Numbe-
red LeDs
lf the Connected LED lights, the Beeper emits 2 beeps,
and the Cross LED lights, the cable has a fault.
Notes:
In the Cross-mode, the Numbered LEDs indicate
connections but do not indicate the location of the cross.
RJ-11 cables used for telephone Connections are often
crossed. Even new cables are often crossed. This
seldom affects the performance of Standard analog
telephone lines (POTS). Digital telephone lines and old
touch-tone phones may be polarity sensitive. so a cros-
sed cable may prevent them from working properly.
7.1 General Information:
The following section provides
information to the user about common cable types,
common failures, and repairs. lt is not meant to be an
exhaustive study of the topic, just some basic informati-
on that the uninitiated may find helpful.
7.2 Cable damage:
When a cable tests badly, either
the wire or the connectors or both may be at fault. lf the
cable has been installed and working, then it‘s likely that
the wire or connectors have been abused in some way.
The wire portion of the cable can be damaged by being
crushed (under the left of a desk), stretched (pulled shar-
ply around a corner), punctured (by a nail or staple), over
loaded (hit by lighting), etc. Similar abuses will damage
the connectors on the ends of the cable. The connectors
can also be damged by excessive insertion and removal
or flexing of the cable close to connector body.
