The 

 4Tx VT 10/100  managed Ethernet switch module

is a member of the 

 product family.  It provides a

compact 4-Port 10/100 Ethernet switch that is expandable
across the 

  19-Module, 5-Module and 2-Module

chassis backplanes, as well as being supported as a
stand-alone switch with the 

 1-Module Chassis.

The 

 4Tx VT supports the IEEE 802.1Q and 802.1p

standards. It supports the 802.1Q VLAN packet tagging and
untagging for segregating data in Enterprise networks, and
enabling secure separation of Service Provider network
management and customer data to improve security and
intrusion protection.

The 802.1Q Q-in-Q stacked tags enable Service Providers to
offer to their customers secure Ethernet Virtual Private Line
services which isolates each customer’s data traffic, as well
as the Service Provider’s management traffic.

The 4Tx VT supports the 802.1p prioritization for the delivery of
Quality of Service (QoS) to real-time applications such as voice
or video over Ethernet.

The 

 4Tx VT features Bandwidth and Port Access

Controls.  On a per port basis, the upstream and downstream
traffic can be independently controlled by selecting from eight
levels of bandwidth setting.  The Port Access Control enables
the network administrator to easily control and deny individual
port access while maintaining port configuration for easy port
re-enabling.

The ports feature 10/100Mbps, Half/Full-Duplex, and auto-
negotiation with both hardware and software controls.  Hardware
control is available for two ports while all four ports are under
software control for these features.  RJ-45 crossover support
eliminates need for a crossover cable and facilitates connectivity
to different types of network equipment.  All four ports support
an automatic crossover detection mode.

Two Ethernet backplane ports provide connectivity to adjacent
modules for network expansion and for providing additional
10/100 UTP ports for 

 modular NIDs.

The 4Tx VT supports reporting of MIB statistics.  Statistics are
available for 32 variables per port, reporting a wide range of
real-time packet statistics to provide performance and
operational monitoring.
