IP•Express GT1 is a high performance, bandwidth scalable, IP WAN router with 4 T1 ports offering a standards based inverse multiplexing (N x T1) capability. The 4 T1 ports are able to connect to 4 remote locations or optionally to be N x T1 inverse packet multiplexed to remote locations from 3 Mbps to 6 Mbps. Standards based WAN protocols, PPP, Multilink PPP, and Frame Relay, ensure interoperability.

The IP•Express GT1 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 T1 CSUs provides for a complete solution with a straight forward configuration.

T1 Branch Office Connectivity

IP•Express GT1 utilizes 4 T1 Telco Circuits to optimally interconnect 4 Remote LANs with IP•Express DLT1s.


Inverse Packet Multiplexing is an option of the IP•Express GT1. IPM delivers 3 to 6 Megabits of interconnectivity over 2,3,4 Dedicated T1 WANs. IETF approved RFC1990 Multilink PPP protocol bonds multiple T1s into a high-speed link that has built-in redundancy. T1 line fault detection provides resilient connectivity for Mission Critical Interconnects.

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 GT1-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.

MPEG IP Multicast Streaming Video

IP•Express GT1-IPM models deliver MPEG IP Streaming Video over Inverse Packet Multiplexed T1s. The Inverse Packet Multiplexer provides the bandwidth necessary for the delivery of 2 broadcast quality video feeds or to deliver near Contribution quality for a single MPEG Video. IP Multicast is a standard feature of the IP•Express GT1 and is utilized to distribute MPEG video simultaneously to multiple decoders.
