|Enable One to Four T1 interfaces for T1 over IP Voice and Data|
The IP•Tube GT1 is available with one to four T1 interfaces and dual 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.
IP•Tube GT1 Standard Features
Transparent InterconnectThe IP•Tube 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 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, theIP•Tube GT1 employs Engage’s robust Assured Delivery Protocol with the following benefits:
• Packet out of sequence detection and re-sequencing
Dual LAN Interfaces
Full T1 Connection Across Two ADSL Lines
Assured Delivery ProtocolIn order to assure high quality communications over links with intermittent or noisy performance, such as Wireless or Broadband over Power Line, the IP•Tube GT1 employs Engage’s robust Assured Delivery Protocol with the following benefits:
|Service Quality Packet Prioritizing|
The IP•Tube GT1 uses the Type of Service byte in the IP packets to prioritize the encapsulated T1 frames. The setting of the TOS byte can be used to ensure that the real time TDM data from the IP•Tube GT1 is ensured high priority.
VPN Network Management
IP•Tube GT1 Options
Lossless Data Compression OptionThe IP•Tube GT1C 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. Management of the IP•Tube GT1 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
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 -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 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.
Pay-As-You-Grow Field Upgrades
The IP•Tube GT1 are designed for Pay-As-You-Go growth from 1 T1 thru 4 T1s per IP•Tube GT1. Customers can elect to economize initial network installations, by purchasing their IP•Tube 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 IP•Tube GT1 can be upgraded to Lossless Data Compression with a simple software-based license key installation. If upon installation, you determine that your IP•Tube GT1s 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 easily installed in 19" and 23" racks. Easy access to both front and rear sides facilitates technician maintenance procedures.
The most compelling option for the interconnection of T1 based systems is when it can be accomplished over a Local Area Network. The deployment of Fiber based LANS such as FDDI and Gigabit Ethernet, provides organizations with high performance and high quality bandwidth that is especially well suited for the interconnection of PBXs and Telecom Switches.
Wide Area Networks, that have sufficient bandwidth and Quality of Service provisioning, facilitate a very very significant cost savings especially for Multinational Corporations. The IP•Tube GT1C, a model with lossless data compression, detects idle and redundant data within each voice circuit resulting in a 56 to 1 bandwidth savings. WAN bandwidth is not consumed by silence or redundant circuits.
IP Cellullar Back Haul
IP•Tube GT1s are used to provide transparent interconnection of the base stations (BTSs), base station controllers (BSCs) and mobile switching centers (MSCs) over IP/Ethernet packet-switched networks. Supported access media include fiber, coax and fixed wireless. Cellular phone service providers are able to save substantially by converting to a packet-switch network from circuit TDM lease lines. The IP•Tube GT1 has the duplicate packets transmission and reception feature that provides for resilient performance through a lossy interconnect.
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 IP•Tube T1 Over Ethernet capability.
CLEC PBX Back Haul
The IP•Tube GT1 provides CLECs with a way to back haul T1 DS0s from a customer’s phone systems over their Internet connection. The back hauled DS0s are connected to the CLECs phone switch for connection to the Public Switched Telephone Networks. Competitive Local Exchange Carriers are able to provide customers with a very economical alternative to the local Phone Company since the Local Loop charges for each phone line are consolidated.
Telcos reduce costs by delivering profitable leased and private line services over their flexible Ethernet infrastructures.
International Toll Bypass
The IP•Tube GT1'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.
