T1 TDM Voice Over IP Extender IP Tube DLT1-Ecan
Extend T1 TDM Over IP T1oIP

The IP•Tube DLT1-Ecan encapsulates full and fractional T1 circuits into IP packets. T1 Over IP connections provide for the interconnection of PBXs and Telecom Switches via LANs, WANs, MANs, Satellite and Wireless Ethernet.

The IP•Tube DLT1-Ecan ships with two T1 interfaces with either 1 or 2 active and two 10/100 BaseT Ethernet Interfaces. The inactive T1 Port can be activated via a software-based license key for a pay as you grow option.

Transparent Interconnect The IP•Tube DLT1-Ecan’s transparent operation maintains the proprietary signaling required to support PBX features such as call conferences, call forwarding, caller ID and SS7.

Multi-Site Enterprises, 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 Phone Systems.

The IP•Tube DLT1-Ecan 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
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-Ecan-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.

Echo Canceller

The IP•Tube DLT1-Ecan has an integrated T1 Echo Canceller that cancels up to 64 milliseconds of Far End echo. The echo canceller meets ITU-T G.164, G.165 and ITU-T G.168 requirements for echo cancellation.

Signaling Support PRI ISDN, SS7, ESF, D4, SLC-96, Proprietary out of band, and robbed bit signaling is supported. Echo cancellation is automatically disabled during FAX and Modem communications. Transparent support for Modem or Fax. Voice quality is not compromised. Legacy phone equipment investment is preserved.

IP•Tube DLT1-Ecan Standard Features
Assured Delivery Protocol In order to assure that circuits are extended over connections with fault tolerance the IP•Tube DLE1-Ecan has as a standard capability an Assured Delivery Protocol that supports high performance full duplex real time data. The protocol has packet out of sequence detection and re-sequencing, duplicate skipping, and real time lost packet retransmission with configured delay. Dual LAN Interfaces All IP•Tube•DLT1-Ecan models ship with dual 10/100BaseT Ethernet LAN ports. The dual Ethernet interfaces provide for: • Management interface on LAN port 2 when LAN port 1 is connected to a VPN tunnel • The LAN ports can be configured to support connections over 2 opposite ADSL links • Alternator Option for load balanced SDSL interconnects • Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria VPN Network Management Interconnecting the IP•Tube DLT1-Ecan through a Virtual Private Network with sufficient real time committed information rate ensures that the required quality of service is provisioned. The second Ethernet interface provides a management port. Each LAN interface features independent IP network configurations.
IP•Tube DLT1-Ecan Options
Lossless Data Compression Option Lossless Data Compression OPTION The IP•Tube DLT1-Ecan-C continuously detects idle and redundant data within each T1 Voice circuit resulting in as much as a 56 to 1 bandwidth savings. TDM over IP WAN bandwidth is not consumed by silent or redundant circuits. Note: Compression only supported with IPTube•DLT1-Ecan-C models.
Alternator Load Balancing Option The IP•Tube DLT1-Ecan-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.

Protector Option 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. Pay-As-You-Grow Field Upgrades The IP•Tube DLT1 Ecan 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-Ecan is best deployed with Loss less Data Compression, your still in business with the per port field upgrade!
Rack Mount Kit The IP-Tube family is ready for central office or data center environments with 19" and 23" Rack Mount Kits.
