Connecting to the line
The method used to connect to the line varies depending on the test mode and line
configuration.
Connecting to a single twisted pair
1. Using the RJ-45 to telco clips cable, connect the RJ-45 to bed of nails test lead to
the DSL connector on the right panel of the OneExpert DSL.
2. Connect the RJ-45 to bed of nails test leads to the desired pair, black to tip (A) and
red to ring (B).
NOTE: If you have the ONX-TM-SCKP-212 module installed, use the RJ-11 jack instead of the
RJ-45 jack.
The line is connected.
Connecting to bonded twisted pairs
1. Using the RJ-45 to telco clips cable, connect the RJ-45 to telco clips test lead to the
DSL connector on the right panel of the OneExpert DSL.
2. Connect the RJ-45 to telco clips test leads to the pairs: black to tip (A) and red lead
to ring (B) for pair one; blue to T1 and yellow to R1.
NOTE: If you have the ONX-TM-SCKP-212 module installed, use the RJ-11 jack instead of the
RJ-45 jack.
The line is connected. The modems begin to train on the lines automatically.
If one of the pairs is not capable of bonding, or the pairs do not bond, a red error message
box appears.
NOTE:
You may see both lines sync, drop, and then re-sync again.
This is typical for bonded lines. The modems include a test
probe that syncs both pairs, drops, and then re-syncs in
bonded mode.
Connecting to a single pair at the NID/demarc
1. Connect the single end of the test cable to the jack on the side of the OneExpert
DSL.
2. Connect the blue end of the cable to Modem on the NID/demarc.
The line is connected.
NOTE: This connection is not used by the ONX-TM-SCKP-212 module.
