IPTube GE1

g703 to Ethernet

Overview

Enable 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 independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. Enable additional E1 Ports as needs expand using a software-based license key. The protocols supported are IPTube, CESoIP, and HDLCoIP.

IPTube GE1Standard Features


 

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

Dual LAN Interfaces
All IPTube GE1 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 

Full E1 Connection Across Two ADSL Lines
The IPTube GE1's two Ethernet interfaces are able 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 IPTube 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 IPTube 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 IPTube GE1 is ensured high priority.

VPN Network Management
Interconnecting the IPTube GE1 through a Virtual Private Network with a sufficient real time committed information rate ensures that the required quality of service is provisioned. The IPTube GE1's second Ethernet interface provides a management port when the first Ethernet interface is connected to a VPN. Each Ethernet LAN interface features independent IP network configurations.

IPTube GE1 Options


 

Lossless Data Compression Option
 The IPTube 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 IPTube GE1 is accomplished with a Command Line Interface that is accessed through a Console or Telnet connection. Common templates provide for cut and Paste configuration.

Alternator Load Balancing Option
The IPTube 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.

SuperTube Option
Engage Communication super sizes IPTube's T1/E1 Circuit extension over Ethernet Packet networks.  The Engage SuperTube option combines four T1/E1 circuits into one IP packet stream.  The SuperTube is designed to support Cellular Backhaul’s tight latency requirements when multiple T1/E1 circuit interconnects are to be extended over Packet networks.

 

Multiplexed T1 over Ethernet

 

The typical way to extend T1/E1 circuits across packet networks is for each T1/E1 to be encapsulated into individual IP packet streams.  The SuperTube Sized IPTube reduces the encapsulation overhead bandwidth and the packet frequency by 75%. The reduction of packet frequency enables network processors that are pressed with the low latency packet processing.

Cellular Backhaul has latency requirements that can be as stringent as four milliseconds.  In order to rate adapt the clock and to take into account the jitter of the Ethernet buffering of the circuit extended packets is required.  The frequency of the packets may need to be as low as 250 micro seconds to meet the latency and buffering requirements. 

The packet processing for 4 bidirectional T1/E1 circuits at 250 microseconds packet interval full duplex is 32,000 packets per second.  32,000 packets per second full duplex is not something that 802.xx and WiMax wireless radios are able to reliably process.   The SuperTube option cuts the packet processing requirement to 8,0000 packets per second which can be handled with ease by commercial grade 802.xx and WMax radios.

Protector Option
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.

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 IPTube GE1 are designed for Pay-As-You-Go growth from 1 E1 thru 4 E1s per IPTube GE1. Customers can elect to economize initial network installations, by purchasing their IPTube GE1 with a single active E1 port. As the network grows enable additional E1 Ports via a software-based license key. Field upgrade benefits are extended to our Industry-Best Lossless Data Compression. Just as E1 ports are field upgradeable, so is Lossless Data Compression. At any time, each E1 port on the IPTube GE1 can be upgraded to Lossless Data Compression with a simple software-based license key installation. If upon installation, you determine that your IPTube GE1s are best deployed with Lossless Data Compression, you're still in business with the per port field upgrade!

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