IP•Tube DLE1

The IP•Tube DLE1 encapsulates full and fractional E1 circuits into IP packets. E1 Over IP connections provide for the interconnection of PBXs and Telecom Switches via LANs, WANs, MANs, Satellite and Wireless Ethernet. 

The IP•Tube DLE1 ships with two E1 interfaces with either 1 or 2 active and two 10/100 BaseT Ethernet Interfaces. The E1 interfaces have configurations that for provide independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. The inactive E1 Port can be activated via a software-based license key for a pay as you grow option.

The IP•Tube DLE1'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.

PRI ISDN, SS7, and Proprietary out of band are supported. Transparent support for Data, Modem or Fax. Voice quality is not compromised.

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 DLE1 employs Engage’s robust Assured Delivery Protocol with the following benefits:

• Packet out of sequence detection and re-sequencing
• Lost packet retransmission with configured delay
• Duplicate skipping

• 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

All IP•Tube DLE1's two Ethernet interfaces are able utilize two ADSL Ethernet Modems, that have opposite high speed direction, to transport an E1’s symmetrical bandwidth.

Interconnecting the IP•Tube DLE1 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.

The IP•Tube DLE1-MUX maps DSOs from a central site to as many as 31 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.

The E1 switch option enables the E1 Port 1 interface to be manually switched between a E1 circuit connected to E1 Port 2 or to E1 Over IP packets connected with the remote IP•Tube.

• Remote Control of E1 Connection to Telco or E1 over IP
• Installation performed by a single Technician
• Quick reversion to Telco during debug of E1 over IP

The E1 Link Protector provides an automatic back up for E1 circuits with E1 Over IP connecting via Wireless Ethernet, Gigabit Ethernet, IP Satellite Services, xDSL,...

• Automatic Protection Switch for E1 Circuit
• Deliver on Stringent Service Level Agreements
• Back Up for Mission Critical Connectivity
• Disaster Recovery for Public Safety Network

The IP•Tube DLE1-C continuously detects idle and redundant data within each E1 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 DLE1-C models.

The IP•Tube DLE1-ALT Alternator option alternatively sends the IP packetized E1 frames on LAN 1 and LAN 2. The Alternator option enables fractional and full E1 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.

The IP•Tube DLE1-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 E1 Over IP real time connections. Great for Wireless WAN E1 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.

The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated E1 Circuit. The extension of the E1 circuit has a fault tolerant link that is configured to always on, or with switch over criteria. 

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. 

The IP•Tube DLE1 are designed for Pay-As-You-Go growth from 1 E1 to 2 E1s. Customers can elect to economize initial installations, buy purchasing a single active E1 port and enable the additional E1 Port via a software-based license key. Field Upgrade benefits are extended to our Industry-Best Loss less Data Compression. Just as E1 ports are field upgrade able, so is Loss less Data Compression. At any time, each E1 port on the IP•Tube DLE1 can be upgraded to Loss less Data Compression with a simple software-based license key installation. If you determine that your IP•Tube DLE1 is best deployed with Loss less Data Compression, you're still in business with the per port field upgrade!

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.
