IMPORTANT NOTE: The BRX-VDSL2-8 unit is powered from the Sealing Current found on a standard POTS pair.
The BRX-VDSL2-8 will not work on a dry pair (line with no sealing current). Each pair of the BRX-VDSL2-8 is powered
independently with each pair requiring the presence of the sealing DC Voltage for proper operation.
You can also use the BRX Power Injector when deploying the BRX-VDSL2-8 on dry pairs (no POTS service).
Grounding
Lug
Step 1: Select the location where the BRX-VDSL2-8 will be
inserted using the BRX-VDSL2 Calculator for the longest loop
that requires amplication.
Step 2: Connect the grounding lug of the unit to a proper ground
(usually available near the splice point).
Step 3: Insert a BRX-BYPASS-TEST module in slot 1 and ensure
that both switches are in BYPASS mode.
Step 4: Connect the rst two (2) pairs to be amplied to the
rst two (2) pairs of the BRX-VDSL2-8. Make sure to match the
DSLAM pair color to the CPE pair color.
Step 5: Test for continuity between the DSLAM pair and CPE
pair at the splice point. If a pair is powered with a -48Vdc sealing
current, the corresponding LED on the BRX-BYPASS-TEST
module will be ON. If either circuit is not powered, a continuity
test will conrm that the pair is spliced properly (no open, short
or ground fault) but you will need to verify the DSLAM is able to
provide the current. If operating on a dry pair, you should use a
BRX Power Injector.
Step 6: Replace the BRX-BYPASS-TEST module with a
BRX-VDSL2-M module.
Step 7: The DSLAM and CPE will now retrain the circuit and bring
up the ADSL2+ / ADSL link with the amplied bandwidth. Note
that the performance may be limited (or capped) by a setting in
the DSLAM and/or BRAS conguration.
Step 8: Repeat steps 3 to 7 for the other three (3) slots of the
BRX-VDSL2-8 enclosure.
