2 pairs from
the DSLAM
2 pairs to the
subscriber (CPE)
Shielded gel-lled 24 AWG/ 0.51mm cables
IMPORTANT NOTE: The BRX-VDLS2 unit is powered from the Sealing Current found on a standard POTS pair.
The BRX-VDSL2 will not work on a dry pair (line with no sealing current). Each pair of the BRX-VDSL2-2 is
powered independently with each pair requiring the presence of the sealing DC Voltage for proper operation.

Step 1:
Select the location where the BRX-VDSL2-2 will be inserted
as close as possible to the midpoint of the loop.
Step 2:
Connect the grounding lug of the unit to a proper ground
(usually available near a splice point).
Step 3:
Connect one of the DSLAM pairs to a pair coming from the
DSLAM. The corresponding downstream (DS) and upstream
(US) LEDs on the faceplate will turn RED to conrm
presence of -48 VDC sealing current.
Step 4:
Connect the corresponding CPE pair to the pair going to the
subscriber home.
IMPORTANT: Make sure to match DSLAM pair# to CPE pair#.
After step 4, the DSLAM and the CPE will re-train the circuit
and bring up the VDSL2 link with the higher bandwidth. Note
that the performance may be limited (or capped) by a setting
in the DSLAM conguration. During this process, the optimum
amplication gain is automatically determined and both DS
and US LEDs turn solid GREEN. At this point, DSLAM and
CPE are synchronized.
