3.6 TESTING Telephone Line (RJ11) 

3.6.1 Connect the RJ11 test jack to one end of the telephone line to be tested.  

3.6.2 Connect the UAX(Telephone Unit Automatic Exchange)

 

to the other end of the line. 

3.6.3 Push “TEST” button to perform test. 

3.7 TESTING Network Cable (RJ45) 

 

 

● The network tester is suitable for T168A, T568B, 10Base-T and Token Ring. 

The Network Cable Tester will check a fault condition in the above descending order before 

detecting other fault conditions. The detection and indication of the presence of a fault is handled 

on a “

one-per-test

” basis. Once a fault is corrected, it is recommended the cable be tested again 

for other faults.  

OPEN

 There is no “OPEN” indication. A typical cable may have 2, 3, or 4 pairs. OPENS are displayed 

as an unlit symbol. The user will determine if a pair is present and continuous or OPEN by comparing 

the illuminated symbol to the expected number of pairs that should be good.  

SHO.

 A short circuit condition exists (see Fig.1). 

MIS.

 Indicates the improper assignment of individual wire pairs to pins for the wiring schemes tested 

(see Fig.2).  

REV.

 Reverse wiring means the pin for one wire in a pair is connected to the opposite pin for the 

pair in the remote jack (see Fig.3). 

SPL.

 Split pairs occur when the tip (positive conductor) and ring (negative conductor) of two twisted 

pairs are interchanged (see Fig.4). 

 

 

 

CAUTION! DO NOT use on the circuits as it may damage the tester.
