Testing two pair Token-Ring cables is similar to testing the
Ethernet cables. The difference is that instead of pairs 1/2 and
3/6, the usable readings occur on pairs 3/6 and 4/5. Pairs 1/2
and 7/8 will display (OP), as described on the previous page.
SPECIFICATIONS
CABLE TYPES:
EIA/TIA 568 configuration for UTP Ethernet and
Token Ring.
CABLE PAIRS TESTED:
1/2, 3/6, 4/5, 7/8
CONNECTOR:
RJ-45
FAULTS DETECTED:
Open pairs, Shorted pairs, Crossed pairs,
Spilt Pairs, Transposed Pairs, Reversed pairs, and Double Spilt
pairs – NEXT less than 21 dB +/- 4dB
DIGITAL DISPLAY:
Two seven segment displays, Four PASS
LEDs (Green), Four FAIL LEDs (Red)
INPUT PROTECTION:
Withstands 56 VDC limited by 400 ohms
series resistance. Withstands 175 V peak 20 – 60Hz with 100
ohms series impedance superimposed onto 56 VDC for 100
mS. (Standard TELCO signals).
