T1 Over IP

The IPTube•QT1's transparent operation maintains the proprietary signaling required to support PBX features such as call conferencing, call forwarding, caller ID and SS7. Legacy phone equipment investment is preserved. Transparent support for Modem, Fax, or Data circuits. Voice quality is not compromised.

HDLC over IP
IPTubes with HDLCoIP connect to the T1 leased line interface of an Enterprise's WAN Router and encapsulate the HDLC frames into an IP Packet that is sent to the remote site IPTube where it is presented to the remote WAN router as the original HDLC frame. Enterprises are able to connect to broadband IP services through their existing proven WAN infrastructure. Internal Ethernet networks remain isolated and security services such as Firewalling are maintained.

Engage Communication's Central Office T1 Over IP Solution Deployed by Cellular Service Providers and Nationwide MSO

APTOS, Calif., March 23, 2004 - Engage Communication's IPTube•QT1 provides service providers, enterprises, and government agencies with a very cost effective, Central Office solution for interconnecting T1 based Telecommunication equipment from one to four remote sites over LANS, WANS, MANs, Satellite, and Wireless Ethernet.

Cellular Service providers have deployed the IPTubeQ1-C for interconnecting Cellular Base Stations to Base Station Controllers over an IP interconnect. An international Service provider is saving over $5,000 per month per link. The IPTube•QT1•C model, with integrated lossless compression of 56 to 1, minimizes the committed information rate required from their IP WAN service provider.

A major nationwide MSO is interconnecting Telecommunication switches across their HFC network with IPTube•QT1s. The MSO is positioned to compete with incumbent carriers for a major piece of the lucrative T1 leased line service with a solution that works at the T1 frame level which provides for transparent interoperability with legacy PBXs.

"The success of the IPTube•QT1 product is the direct result of high quality customer feedback." said Mark Doyle President. "The platform utilized by the IPTubeQT1, which encompasses 15 years of networking and telecommunication expertise, positions Engage as a Central Office solution provider."

The IPTubeoQT1 is available with one to four T1 interfaces and a 10/100 BaseT Full/Half Duplex Ethernet Interface. The T1 interfaces have configurations that provide for independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. The protocols supported are IPTube, CESoIP, and HDLCoIP.

Engage also manufactures the IPTube•QE1, an E1 version. In transparent mode the E1 is able to interoperate with the T1 tubes.
