Network Cabling and Connections

Connect to the DES-7010 Ethernet over VDSL Module

The network connections to the DES-7010 Ethernet over VDSL module are provided using Telco 50

cabling to connect to two male RJ-21 ports at the front panel of the module. These ports are labeled

PSTN and VDSL. These connections are defined as follows:

§ PSTN – Use a female RJ-21 connector and Telco 50 cabling to connect the system to a

PBX system or other appropriate connection to the Public Switched Telephone Network.

This provides the uplink to the VDSL service from the telephone or networks services

provider.

§ VDSL – Use a female RJ-21 connector and Telco 50 cabling to connect up to 24 VDSL

subscriber ports (i.e. connect to one remote CPE unit per port) to the module. The

switch/module to end users connection can be done through a variety means depending on

the circumstances including using a Main Distribution Frame, Cabling Cabinet, patch panels

or other suitable wiring systems. This provides the combined data and voice channels to the

VDSL accounts.

The per port LED Link indicators on the DES-7010 will:

§ Light green when a link has been established

§ Remain dark when there is no link
