The iConverter 4Tx VT is a compact 4-Port Ethernet switch module and is a member of the managed iConverter product family.

The 4Tx VT supports Half or Full-duplex 10/100Mbps auto-negotiation, and features flexible hardware and software controls. Two ports can be controlled by DIP-switches and all four ports can be controlled via SNMP management. The 4Tx VT supports auto-crossover (MDI/MDI-X) on all four ports, eliminating the need for a crossover cable and facilitating connectivity to different types of Ethernet equipment.

The iConverter 4Tx VT complies to 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 iConverter 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 iConverter 4Tx VT can be used in managed or unmanaged applications. Management is accomplished by installing an iConverter Management Module (NMM2) or Network Interface Device (NID) in the same chassis. The management module provides access to all the advanced features available on the module.

The hot-swappable plug-in module can be mounted in a 19 or 5-Module iConverter chassis with redundant AC and DC power supplies. It can also be mounted in a 2-Module AC or DC powered chassis, or in a 1-Module chassis with AC or DC power input.

Compact Switch Configurations

iConverter compact chassis support Ethernet backplane connectivity between plug-in modules. Modules can be combined to create configurations that provide multi-port Ethernet connectivity to end users and subscribers.

The example below illustrates a 4Tx VT module and a 10/100M2 intelligent media converter installed in a 2-Module chassis. This configuration provides a Fast Ethernet fiber uplink and five managed 10/100BASE-T ports.
