 Enables One to Four E1 Interfaces for E1 over IP Voice and Data:

The IPTube GE1 is available with one to four E1 interfaces and a 10/100 BaseT Full/Half Duplex Ethernet Interface. The E1 interfaces have configurations that provide for independant protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. Enable assitional E1 Ports as needs expand using a software-based license key. The protocols supported are IPTube, CESoIP, and HDLCoIP. 

IP Tube GE1 Standard Features:

Transparent Interconnect 

The IPTube GE1's transparent operations maintains the proprietary signaling required to support PBX features such as call conferencing, call fowarding, caller ID and SS7. Legacy phone equipment investment is preserver. Transparent support for Modem, Fax, or Data Circuits. Voice quality is not compromised.

Assured Delivery Protocol 

In orde to assure high quality communications over links with intermittent or noisy performance, such as Wireless or Broadband over Power Line, the IPTube GE1 employs Engage's robust Assured Delivery Protocol with the following benifits:

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

Dual LAN interfaces

All IP Tube GE1 modes ship with dual 10/100BaseT Ethernet LAN ports. THe dual Ethernet interfaces provide for:

  • Management interfaces 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
Full E1 Connection Across Two ADSL Lines

The IP Tube GE1's two Ethernet interfaces are able to utilize two ADSL Ethernet Modems, that have opposite high speed direction, to transport a E1's symmetrical bandwidth.

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 GE1 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
Service Quality Packet Prioritizing

The IP Tube GE1 uses the Type of Service byte in the IP packets to prioritize the encapsulated E1 frames. The setting of the TOS byte can be used to ensure that the real time TDM data from the IP TUbe GE1 is ensured high priority.

VPN Network Management 

Interconnecting the IP Tube GE1 through a Virtual Provate Network with a sufficient realt time committed information rate ensures that the required quality of service is provisioned. The IP Tube GE1's second Ethernet interface provides a management port when the first Ethernet LAN interfaces features independant IP network configuarations.



IP Tube GE1 Options: 

Lossless Data Compression Option 

The IP Tube GE1C detects idle/redundant data within each DS0 resulting in as much as 40 to 1 bandwidth savings. E1 over IP bandwidth is not consumed by silent or redundant circuits. Management of the IP Tube Ge1 is accomplished with a Command Line Interface that is accessed through a Console or Telnet connection. Common templates provide for cut and paste configuaration.



Alternator Load Balancing Option 

The IP Tube GE1-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 cost of interconnecting E1 communication systems across packetized xDSL is a fraction of long distance leased E1 circuit costs.


Protector Option 

The protector option utilizes the second LAN interfaces 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.

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 IPTube 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 

The IP Tube GE1's are designed for Pay-As-You-Go growth from 1 E1 thru 4 E1s per IP Tube GE1. Customers can elect to economize intitial network installations, by purchasing their IP Tube GE1 with a single active E1 port. As the network grows enables additional E1 Ports via asoftware-based license key. Field upgrade benifits are extended to our industry-best Lossless Data Compression. Just as E1 ports are field upgradable, so is Lossless Data Compression. At any time, each E1 port on the IP Tube GE1 can be upgraded to Lossless Data Compression. At any time, each E1 port on the IP Tube GE1 can be upgraded to Lossless Data Compression with a single software-based license key installation. If upon installation, you determine that your IP Tube Ge1s are best deployed with Lossless Data Compression, you're 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 easlity installed in 19" and 23" racks. Easy access to both front and rear sides facillitates technician maintenance procedures.
