Tag VLAN, Port VLAN and QoS
The iConverter 4GT supports the IEEE 802.1Q tag Virtual Local Area Network (VLAN) packet tagging and untagging (including Q-in-Q) and the 802.1p Quality of Service priority standards.
4GT VLAN 802.1ad tunneling technology enables service providers to offer their customers E-Line and E-LAN services (via Ethernet Virtual Circuit or EVC), which connect multiple business LANs at different locations and make their networks appear to be on the same local network. Q-in-Q Service tags transparently transport customer network traffic across the service provider network, isolating it from other customer and service provider management traffic.
The 802.1p prioritization standard enables delivery of Quality of Service (QoS) to high-priority, real-time applications such as voice and video over Ethernet.
Port VLAN enables the ability to specify and restrict traffic flow between the RJ-45, backplane and management ports.
Port Bandwidth Control and Port Access Control
The enhanced Bandwidth Control feature supports bandwidth limiting for the RJ-45 ports in 64Kbps increments from 64Kbps to Full Line Speed.
The 4GT features Port Access Control which blocks user service while maintaining the network link. Port Access Control enables the network administrator to control user access while maintaining port configuration for easy disabling or enabling of user service. Port Access Control provides administrators the capability to improve network security by controlling port access when the port is not in use.
Port Statistics
The 4GT supports reporting of utilization and port statistics. Port statistics are available with 38 different variables for each port. Port statistic reporting provides the ability to monitor bandwidth utilization and network performance for each individual port.
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 4GT module and a GX/TM2 intelligent media converter installed in a 2-Module chassis. This configuration provides a Gigabit fiber uplink and five managed 10/100/1000BASE-T ports.
