2.3 Wiring for VDSL2 Ports
The VDSL2 port of VC-2400MR series uses one RJ-21 (Telco 50) connector to connect to a patch panel then link up to 24
VDSL CPEs and the VDSL2 port of VC-820M uses eight RJ-11 connectors which can be just directly connected to the
remote CPEs (VC-230, VC-230N, VC-231, VC-234 or other compatible CPE) through structured or unstructured wiring,
such as existing telephone lines. The link between the VDS2L CO Switch port and each CPE can reach speeds of up to
100/100 Mbps under 1000 feet (300 meters) with profile 30a or 18/1 Mbps over distances of up to 5000 feet (1500 meters).
You can hot swap the VDSL2 CPEs without powering down the Managed Switch or disrupting the other switch ports.
Each VC-820M and VC-2400MR series VDSL2 Managed Switch series had built-in Pain Old Telephone service (POTS)
splitter to transmit both VDSL2 traffic and telephone services, such as voice or Fax, through same phone wire. The splitter
routes VDSL2 data (high-frequency) and voice (low-frequency) traffic from the telephone line and Private Branch
exchange (PBX)
switch or Public Switched Telephone Network (PSTN).
The connection diagrams are as the following.

connector is tip and the bottom row is ring.
Figure 2-3-1
shows the pin out convention for the RJ-21 connector.

of the VC-2400MR series, please refer to
for more detail.
The VDSL port and POTS port of VC-2400MR series always connects to a patch panel. The connection between the
VC-2400MR series and the patch panel is made by an RJ-21 Category 5 Telco interface connector and cable, as shown in
Figure 2-3-2
and
