IPTube CEP GT1

PBX over Ethernet, T1 Channel Bank to IP converter

Overview

T1 Voice & Data Over IP / MPLS

The IPTube CEP GT1 encapsulates full and fractional T1 and TDM circuits, along with their framing and signaling bits, into IP packets. The IPTube CEP GT1's T1 Over IP, T1 Over Ethernet connection provides for the transparent interconnection of PBXs, T1 Channel Banks, Telecom Switches and T1 based communication systems via LANs, WANs, MANs, Satellite and Wireless Ethernet.

Transparent Interconnect
The IPTube CEP GT1’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 compromise

Enable One to Four T1 interfaces for T1 over IP Voice and Data
The IPTube CEP GT1 is available with one to four T1 interfaces and three 10/100 BaseT Full/Half Duplex Ethernet Interfaces. The T1 interfaces have configurations that for provide independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. Enable additional T1 Ports as needs expand using a software-based license key. The protocols supported are IPTube, CESoIP, and HDLCoIP.

IPTube CEP GT1 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 IPTube GT1 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.

Three LAN Interfaces

All IPTube CEP GT1 models ship with three 10/100BaseT Ethernet LAN ports. The Ethernet interfaces provide for: 

• Management interface on MLAN 

• Dual Data Plane 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 

Service Quality Packet Prioritizing
The IPTube CEP GT1 uses the Type of Service byte in the IP packets or 802.1p/q mac levels to prioritize the encapsulated T1 frames. QoS is used to ensure that the real time TDM data from the IPTube CEP GT1 is ensured high priority.

IPTube CEP GT1 Management
 IPTube CEPs isolate management and data plane functionality with the use of two separate processor modules. Management processor access is limited to SSH or SNMPv3 encrypted sessions that employ AES 256 bit keys and sophisticated NIST passwords. These sessions may be established after authentication via TACACS+ or Radius.

The independent Linux based management plane of the IPTube CEP ensures Critical Infrastructure Data is isolated from management network access. The Management Module uses internal serial ports to connect to the Data Plane processor.

Administration and User Logs are available with Syslog.

CEP management security features include:

 

• Administrative policies for adding, removing, disabling and renaming authorized users; limiting user access to assigned commands; and enabling only desired port numbers.

• User authentication directly or in conjunction with TACACS+ or RADIUS servers including RSA SecureID support for two factor trusted compliance.

• An SSH command interface encrypting management traffic with powerful 256 bit symmetric keys and NIST based passwords.

• Support of the SNMPv3 protocol for secure connectivity to SNMP element managers.

• In addition, administrative accounting data can be reported to syslog servers with accurate timestamps provided by an NTP source.

 

 VPN Network Management

Interconnecting the IPTube CEP GT1 through a Virtual Private Network with a sufficient real time committed information rate ensures that the required quality of service is provisioned.

The IPTube CEP GT1's Management Plane LAN Ethernet interface provides a management port when the Data Plane Ethernet interface is connected to a VPN. Each Ethernet LAN interface features independent IP network configurations.

IPTube CEP GT1 Options

Lossless Data Compression Option
 The IPTube CEP GT1 detects idle/redundant data within each DS0 resulting in as much as 56 to 1 bandwidth savings. T1 over IP bandwidth is not consumed by silent or redundant circuits.

Alternator Load Balancing Option
The IPTube CEP GT1-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. The cost of interconnecting T1 communication systems across packetized xDSL is a fraction of long distance leased T1 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 E1 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 Data Plane 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.

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 CEP GT1 are designed for Pay-As-You-Go growth from 1 T1 thru 4 T1s. Customers can elect to economize initial network installations, by purchasing their IPTube CEP GT1 with a single active T1 port. As the network grows enable additional T1 Ports via a software-based license key. Field upgrade benefits are extended to our Industry-Best Lossless Data Compression. Just as T1 ports are field upgradeable, so is Lossless Data Compression. At any time, each T1 port on the IPTube CEP GT1 can be upgraded to Lossless Data Compression with a simple software-based license key installation. If upon installation, you determine that your IPTube CEP GT1s are best deployed with Lossless Data Compression, you're still in business with the per port field upgrade!
