Page: 34 / 55

VES-1000 Series Ethernet Switch
4-4 Hardware Connections
4.2.2 VDSL Ports Connections
The VES-1008 has a combined USER/CO Telco-50 connector and this is used for external POTS/ISDN and
VDSL connections. Supplied with the VES-1008 is a cable that is designed to fit into the combined USER/CO
connector and it is a requirement for the installer to configure the other end of the cable to suit their installation
requirements.
The Phone Port pins (pins 1-8 and 26-33) connect to the Main Distribution Frame (MDF) that is usually located in
the multi-tenant unit. Eight separate phone connections from different subscribers are available on the VES-1008
and each of their phone connections are required to be connected to its respective port on the MDF. The VDSL
Port pins are used to connect the VES-1008 to the VDSL modems (for example, ZyXEL’s Prestige 841). As with
the phone port pins, each VDSL port requires 2 separate pins. Eight separate VDSL ports are available on the
VES-1008 and each port is available to a separate user.
Diagram 5 details the pin assignments for the VES-1008 Phone and VDSL ports.
For the VES-1012 only, connect the lines from the user equipment (VDSL modems) to the
USER
port and the
lines from the central office switch or PBX (Private Branch Exchange) to the
CO
port. Make sure that the
USER
line and the
CO
lines are not shorted on the MDF (Main Distribution Frame). Diagram 6 and Diagram 7
respectively show the Phone and VDSL ports on the VES-1012.
The line from the user carries both the VDSL and the voice signals. For each line, switches in the VES-1000
Series have a built-in splitter that separates the high frequency VDSL signal from the voice band signal and feeds
the VDSL signal to the VES-1000 Series switch, while the voice band signal is diverted to the CO port.
See the previous chapter for different VDSL to MDF wiring scenarios.
4.2.3 WAN Port (Ethernet) Connections
For the VES-1008 only, connect ports 9 and 10 of the VES-1008 to a WAN Ethernet switch using straight-through
Category 5 UTP (Unshielded Twisted Pair) cables with RJ-45 connectors. For the VES-1012, connect ports 13
and 14 to an Ethernet switch using straight-through Category 5 UTP (Unshielded Twisted Pair) cables with RJ-45
connectors.
You may stack the VES-1000 Series of Ethernet switches up to the number of ports available on the WAN switch.
If you enable port trunking, make certain that the WAN switch also supports port trunking. See your VES-1000
Series User’s Guide for more details.
