Dead circuit
Open circuit or short
circuit
Break the circuit down into sections and check each
section for continuity.
(2b) When using the test
set in Monitor mode,
or with the test set
disconnected, the
voltage will be
lower
than normal.
(2b) This indicates a partial short circuit.
(2a) When using the test
set in Monitor mode,
or with the test
set disconnected,
the voltage will be
normal
.
(2a) This indicates a high-resistance fault, which
restricts the amount of current flowing through
the circuit. Possible faults include a poor con-
nection, wet cables, or a line extender failure.
Distortion, dialing
difficulty
(1) When using the
test set in Talk mode,
the voltage will be
lower than normal.
Intermittent or
variable current
Wet cables or a bad
connection
If accompanied by noise, the cause is usually wet
cables.
If no noise is present, the cause is probably a bad
connection in a cross-connect or a bad connection
at the central office.
