The IP•Tube DLT1 ships with two T1 interfaces with either 1 or 2 active and two 10/100 BaseT Ethernet Interfaces. The T1 interfaces have configurations that for provide independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. The inactive T1 Port can be activated via a software-based license key for a pay as you grow option.

IP•Tube DLT1 Standard Features

DS0 Timeslot Multiplexor OPTION -MUX
The IP•Tube DLT1-MUX maps DSOs from a central site to as many as 24 remote locations via an IP/Ethernet connection. Get maximum use of expensive DS1 interfaces on PBX, Channel equipment and datacom gear. Also provides Virtual DACS Over IP capability. Mesh DS0s one-to-many or many-to-many.

                           • Remote Control of T1 Connection to Telco or T1overIP
            • Installation performed by a single Technician 
                    • Quick reversion to Telco during debug of T1overIP

    • Automatic Protection Switch for T1 Circuit
          • Deliver on Stringent Service Level Agreements
 • Back Up for Mission Critical Connectivity
        • Disaster Recovery for Public Safety Networks

Lossless Data Compression OPTION - C 

The IP•Tube DLT1-C continuously detects idle and redundant data within each T1 Voice circuit resulting in as much as a 56 to 1 bandwidth savings.

Alternator Load Balancing OPTION -ALT 
The IP•Tube DLT1-ALT Alternator option alternatively sends the IP packetized T1 frames on LAN 1 and LAN 2. The Alternator option enables fractional and full T1 circuits to be split over two IP WAN connections such as xDSL. The Lossless Data Compression option can be combined with the Alternator option to minimize the bandwidth required from the alternative paths.

Full T1 Connection Across Two ADSL Lines
TheIP•Tube DLT1’s two Ethernet interfaces are able utilize two ADSL Ethernet Modems, that have opposite high speed direction, to transport a T1’s symmetrical bandwidth.

Protector OPTION -PRO 
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated T1 Circuit. The extension of the T1 circuit has a fault tolerant link that is configured to always on, or with switch over criteria.

Protector OPTION -EnPRO
The Enhanced version has configuration parameters that enable a secondary packet path with high relative delay to primary path be synchronized. The packet sequence delay synchronization ensures concurrent redundancy with a high degree of error tolerance. Error free operation is accomplished when a primary or secondary Packet is not received and a redundant duplicate packet is available. The IP•Tube also supports the transmission of multiple duplicate packets to support Mission Critical Circuit extension with redundancy that is only limited by the bandwidth provisioned.

Pay-As-You-Grow Field Upgrades
TheIP•Tube DLT1s are designed for Pay-As-You-Go growth from 1 T1 to 2 T1s. Customers can elect to economize initial installations, buy purchasing a single active T1 port and enable the additional T1 Port via a software-based license key.
Field Upgrade benefits are extended to our Industry-Best Loss less Data Compression. Just as T1 ports are field upgrade able, so is Loss less Data Compression. At any time, each T1 port on the IP•Tube DLT1-Ecan can be upgraded to Loss less Data Compression
with a simple software-based license key installation. If you determine that your IP•Tube DLT1 is best deployed with Lossless Data Compression, your still in business with the per port field upgrade!

Rack Mount Kit
The IP•Tube family is ready for your most demanding central office or data center environments. With the Rack Mount Kit, IP•Tube products are easily installed in 19" and 23" racks. Easy access to both front and rear sides facilitates technician maintenance procedures.

Multi-Site Enterprises, Cellular Service Providers, Education Districts, Universities, National, State and Local Government, and Municipalities incur significant recurring monthly costs for rigid-bandwidth leased lines used only for the interconnection of PBXs and Telecom switches.

The IP•Tube DLT1 provides organizations with the ability to interconnect their existing phone systems over flexible bandwidth lines that are used to carry data, voice, and video. The Voice Only Leased Line Toll charges assessed by long distance and local carriers are eliminated or dramatically reduced by transporting voice traffic across LANs and WANs.

LANs
The most compelling option for the interconnection of T1 based systems is when it can be accomplished over a Local Area Network. The deployment of Fiber based LANS such as FDDI and Gigabit Ethernet, provides organizations with high performance and high quality bandwidth that is especially well suited for the interconnection of PBXs and Telecom Switches.

WANs
Wide Area Networks that have sufficient bandwidth and Quality of Service provisioning result in very significant cost savings especially for Multinational Corporations. The IP•Tube DLT1-C with loss less data compression, detects idle and redundant data within each voice circuit resulting in a 56 to 1 bandwidth savings. WAN bandwidth is not consumed by silence or redundant samples.

IP•Tube DLT1s are used to provide transparent interconnection of the Base Stations, Base Station Controllers and Mobile Switching Centers over IP Ethernet packet-switched networks.

Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit based TDM leased lines.

The Loss Less Data compression option provides a 56 to 1 compression, which minimizes the bandwidth required to interconnect, is especially well suited to Cellular communication links. 

Engage's first deployment of the IPTubeT1, in the Spring of 2000, was for an international interconnection of a Cellular Base Station to a Base Station Controller.

Companies, that are able to provide IP Ethernet access networks generate new revenue by offering traditional T1 leased line and private line services, such as:

Cable Operators

Cable operators connect traditional T1 leased line and private line services over their hybrid fiber coax (HFC) cable networks. HFC Cable network latency typically requires echo cancellation.

Metropolitan Area Networks

Metropolitan carriers with IP or Ethernet access networks deliver traditional leased line and private line services.

Utilities

Utilities generate new revenue by offering traditional T1 leased line and private line services over their fiber or power line networks.

Incumbent Carriers

Telcos reduce costs by delivering profitable leased and private line services over their flexible Ethernet infrastructures.

CLEC PBX Back Haul

The IP•Tube DLT1-Ecan provides CLECs with a way to back haul T1 DS0s from a customer’s phone systems over their Internet connection. The back hauled DS0s are connected to the CLECs phone switch for connection to the Public Switched Telephone Networks. Local Exchange Carriers are able to offer an economical alternative to the local Phone Company.
