VES-1124 User’s Guide
3-2 Hardware Connections
The line from the user carries both the VDSL and the voice signals. For each line, the VES has a built-in splitter
that separates the high frequency VDSL signal from the voice band signal and feeds the VDSL signal to the VES,
while the voice band signal is diverted to the CO port.
3.1.3 10/100M Auto-Sensing Ethernet
The VES has 10/100Mbps auto-sensing Ethernet ports. There are two factors related to Ethernet: speed and duplex
mode. In 10/100Mbps Fast Ethernet, the speed can be 10Mbps or 100Mbps and the duplex mode can be half duplex
or full duplex. The auto-negotiation capability makes one Ethernet port able to negotiate with a peer automatically
to obtain the connection speed and duplex mode that both ends support.
When auto-negotiation is turned on, an Ethernet port on the VES negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or
turns off this feature, the VES determines the connection speed by detecting the signal on the cable and using half
duplex mode. When the VES’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and
duplex mode when making a connection, thus requiring you to make sure that the settings of the peer Ethernet port
are the same in order to connect.
You may also bundle the two Ethernet ports into one logical 200Mbps link.
Default Settings
The factory default settings for the Ethernet ports of the VES are:
Speed: Auto
Duplex: Auto
Flow control: Enable
Trunking: Disabled
Use a straight through Ethernet cable when connecting the VES to an Ethernet switch. Use a crossover Ethernet
cable if you are daisy-chaining multiple VESes and make sure trunking is disabled.
