Connecting the POTS/ISDN Ports
The remote (customer premise) VDSL modems will receive there POTS/ISDN connections from the Model
3324 via the VDSL twisted pair. The POTS/ISDN services from a PBX are connected into the 3324 via a RJ-
21X cable. Consult Appendix B,
“Cabling”
on page 77 in order to connect the properly match up the
POTS/ISDN (VOICE) and VDSL Data to the selected VDSL modem port on the Model 3324 and CPE.
1. Connect the RJ-21X connector from a punch down block or directly from the PBX into the 50-pin RJ-
21X receptacle on the front of the 3324 labeled POTS/ISDN.
2. Only 24 of the twisted pairs will be used since there are 24 VDSL modem connections, each being a 2-
wire connection. When inserting the RJ-21 plug, be sure the tab on the plug clicks into position to ensure
that is properly fastened to the Model 3324.
Connecting the VDSL Ports
The remote (Customer Premise) VDSL modems are connected to the 3324 via the RJ-21X cable. Consult
Appendix B,
“Cabling”
on page 77 in order to connect the CP VDSL modems to the selected VDSL modem
port on the 3324.
Note
The 2-wire VDSL modem lines are polarity insensitive so you only
need to match the correct twisted pairs without being concerned
about matching the individual wires of the twisted pair. Wire must be
18–26 AWG (28 gauge or above is
not
recommended).
1. Connect the RJ-21X connector of the cable into the 50-pin RJ-21X receptacle on the front of the 3324
labeled VLINK.
2. The other end of the cable has 25 non-terminated twisted-pairs for connection to punch-down blocks.
Select the twisted-pairs which will be used for active VDSL modem connections and terminate on the
punch-down blocks. Only 24 of the twisted pairs will be used since there are 24 VDSL modem connec-
tions, each being a 2-wire connection. When inserting the RJ-21 plug, be sure the tab on the plug clicks
into position to ensure that is properly fastened to the Model 3324.
3. Select and attach the appropriate twisted pair from each remote (CP) VDSL modem on punch-down
blocks for connection to the chosen VDSL port in the Model 3324.
