T1 Ethernet Converter
Overview & Applications
| T1 Voice and Data Over IP The IP•Tube DLT1 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. Transparent Interconnect The IP•Tube DLT1's transparent operation maintains the proprietary signaling required to support PBX features such as call conferences, call forwarding, caller ID and SS7. Legacy phone equipment investment is preserved. Signaling Support 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

Assured Delivery Protocol In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless or Broadband over Power Line, the IP•Tube DLT1 employs Engage’s robust Assured Delivery Protocol with the following benefits: • Packet out of sequence detection and re-sequencing • Duplicate skipping, • Lost packet retransmission with configured delay. Dual LAN Interfaces All IP•Tube DLT1 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 Virtual Private Network Support Interconnecting the IP•Tube DLT1 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 OPTIONS | |
DS0 Timeslot Multiplexor OPTION -MUX
| |
| T1 Switch OPTION - SWT The T1 switch option enables the T1 Port 1 interface to be manually switched between a T1 circuit connected to T1 Port 2 or to T1 Over IP packets connected with the remote IP•Tube. • Remote Control of T1 Connection to Telco or T1overIP
| |
| T1 Link Protector OPTION -LPT The T1 Link Protector provides an automatic back up for T1 circuits with T1 Over IP connecting via Wireless Ethernet, Gigabit Ethernet, IP Satellite Services, xDSL,.... • Automatic Protection Switch for T1 Circuit
| |
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. TDM over IP WAN bandwidth is not consumed by silent or redundant circuits. Note: Compression only supported with IP•Tube•DLT1-C models. |
|
Alternator Load Balancing OPTION -ALT Full T1 Connection Across Two ADSL Lines | |
 | |
Rate Limiter OPTION -RLM The IP•Tube DLT1-RLM Rate Limiter option limits the WAN bandwidth utilized by the LAN1 to LAN2 bridge. Rate Limiting the traffic enables the reservation of the WAN bandwidth for time the sensitive T1 Over IP real time connections. Great for Wireless WAN T1 applications. Rate Governing is only applied in the direction to the WAN to minimize latency. The data rate governor utilizes Time Division Multiplexing based clocking to provide for Nx64, NxE1 and NxFT3 bandwidth regulation that is configured from 64 kilobits up to 45Mbits.

Applications
| T1 Private Line Services Over IP | |
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 WANs

| Cellular Base Station Backhaul | |
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.  | |

| Wireless Ethernet Connecting phone systems across a wireless Ethernet connection has a return on investment that is measured in weeks. Eliminating the wired connection for the T1 based communication equipment is made possible with the IPTube’s T1 Over Ethernet capability. | |
International Toll Bypass The IP•Tube T1’s most dramatic cost savings is when it is used for the international interconnections of TDM based telecommunication equipment. The IP•Tube E1 is interoperable with the European TDM standard E1.
