  • Shared Internet Access
  • Branch Office Connections
  • Education District Networking
  • Multimegabyte File Transfers
  • MPEG Video Distribution

Inverse Packet Multiplexing
Inverse Packet Multiplexing is a feature of the IP Express MLBH-E1 IPM delivers 3 Megabits of interconnectivity over Dedicated E1 WANs. Built in E1 line fault detection provides for automatic bandwidth backup for Mission Critical Fault Tolerant Interconnects. Security is provided with Full On Source, Destination Address; Port and Flag IP Packet filtering. Interconnectivity is able to be selectively controlled at the network, device and application layers.


MPEG IP Multicast Streaming Video Delivery
IP Express MLB-E1 IPM models delivers MPEG IP Streaming Video over Inverse Multiplexed E1s. The Inverse Packet Multiplexor provides the bandwidth necessary for the delivery of broadcast quality Streaming IP Video. IP Multicast is a standard feature of the IPExpress and is utilized to distribute MPEG video simultaneously to multiple decoders.

MPEG IP Video Redundancy Switch
REDundant IP Video configuration that automatically switches from the Primary to a Secondary Encoder's IP Video Stream for mission critical broadcasts and is only available with the IP Express MLBH-E1 IPM-RED. A one second absence of IP packets from the Primary Encoder results in the switch to the Secondary Encoder. The WAN bandwidth is reserved for a single feed. The Redundancy option is also available with the Inverse Packet Multiplexor.
