• IP WAN Router with Four Integrated T1 DSU/CSUs •

IP•Express•QT1 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 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. IP•Express•QT1 Brochure in PDF

The IP•Express•QT1is a very reliable, high performance and cost effective IP WAN Router for interconnecting remote LANs and addresses the large market for connectivity in the multi-megabit bandwidth range such as high performance MPEG Video delivery. The Integration of the T1 CSUs provides for a complete solution with a straight forward configuration. It is great for:

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

Inverse Packet Multiplexing
Inverse Packet Multiplexing is a feature of the IPExpress•QT1•IPM. 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 virtual link that has built-in redundancy. T1 line fault detection provides resilient connectivity for Mission Critical Interconnects.

High Performance Fault Tolerant Internet Access
Internet Service Providers deploy the IP•Express•QT1 as a customer premise solution for customers that require Fault Tolerant NXT1 multimegabit access to the Internet. Industry Standard Multilink Point to Point Protocol ensures interoperability with the Internet Service Providers Point of Presence solution.

MPEG IP Multicast Streaming Video Delivery
IPExpress•QT1•IPM models deliver MPEG IP Streaming Video over Inverse Packet Multiplexed T1s. The Inverse Packet Multiplexor 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 IPExpress•QT1 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 IPExpress•QT1•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.

Headquarters IP WAN Router
The IPExpress•QT1 is a great solution for connecting four remote locations to a central site.


IP•Express•QT1 models packs 4 T1 WAN connectivity into 1/3 of a 19" wide rack
