The IP•Express DLE1 interconnects remote LANs and addresses the large market for connectivity in the multi-megabit bandwidth range such as high quality MPEG Video delivery. The Integration of the E1 CSUs provides for a complete solution with a straight forward configuration.

E1 Branch Office Connectivity:



Two E1 Inverse Packet Multiplexor:

Inverse Packet Multiplexing is an option of the IP Express DLE1. IPM delivers 4 Megabits of interconnectivity over 2 Dedicated E1 WANs. IETF approved RFC1990 Multilink PPP protocol bonds multiple E1s into a high-speed link that has built-in redundancy. E1 line fault detection provides resilient connectivity for Mission Critical Interconnects.

MPEG IP Multicast Streaming Video:

IP Express DLE1-IPM models deliver MPEG IP Streaming Video over Inverse Packet Multiplexed T1s. The Inverse Packet Multiplexor provides the bandwidth necessary for the delivery of broadcast quality video feeds for a single MPEG Video. IP Multicast is a standard feature of the IP•Express DLE1 and is utilized to distribute MPEG video simultaneously to multiple decoders.

MPEG IP Video Redundancy Switch: 

REDundant IP Video configuration automatically switches from the Primary to a Secondary Encoder's IP Video Stream for mission critical broadcasts and is available with the IP Express DLE1-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.
