Wiring for VDSL ports

The VDSL port of VC-1602 uses one RJ-21 (Telco 50) connector to connect up to 16 VDSL converters (VC-102S, VC-101S or Cisco LRE modem) through structured or unstructured wiring, such as existing telephone lines. The link between the VDSL switch port and each converter can reach speeds of up to 15/17 Mbps over distances of up to 5000 feet (1500 meters). You can hot swap the VDSL converters without powering down the switch or disrupting the other switch ports.

If telephone services, such as voice or an Integrated Services Digital Network (ISDN), use the same cabling as VDSL traffic, the VDSL port must be connected to the patch panel through a plain old telephone service (POTS) splitter. The splitter routes VDSL data (high-frequency) and voice (low-frequency) traffic from the telephone line to the switch and private branch exchange (PBX) switch or public switched telephone network (PSTN).

The connection diagram is as the following.

If the port is connected but the relevant LED is dark, check the following items:

1.The switch and the connected device’s power are on or not.

2.The connecting cable is good and with correct type.

3.The cable is firmly seated in its connectors in the switch and in the associated device.

4.The connecting device, including any network adapter is well installed and functioning.

5.Confirm the CPE device is implemented within the scope of operative without interference.

For more information about the splitter, please consult your local dealer about the splitter and refer the user’s guide of the splitter.

PLANET VC-1602 products are designed to share lines with analog, Integrated Services Digital Network (ISDN), and digital private branch ëNote exchange (PBX) switch telephones that use the 0 to 700 kHz frequency range. Digital telephones connected to digital PBX switches that use frequencies above 700 kHz do not work when sharing a line with LRE signals. Due to the proprietary nature of digital PBX switches, some digital PBX switch services use frequencies above 700 kHz. Besides, digital telephones connected to digital PBX switches that use frequencies above

700 kHz will not work when sharing a line with LRE signals.
