IP•Tube 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 IP•Tube 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 IP•Tube 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 IP•Tube 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 IP•Tube CEP GT1 is ensured high priority.
IP•Tube CEP GT1 Management
IP•Tube 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 IP•Tube 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 IP•Tube 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 IP•Tube 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.
IP•Tube CEP GT1 Options
Lossless Data Compression Option The IP•Tube 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 IP•Tube 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.

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 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 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 IP•Tube 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 IP•Tube CEP 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 CEP 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.

Applications

T1 to Ethernet T1 Channel Bank to MPLS IP


LANs 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.
WANs 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 CEP GT1, 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 CEP 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.

Wireless Ethernet 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’s T1 Over Ethernet capability.

IP/Ethernet Service Providers Companies, that are able to provide IP/Ethernet access networks generate new revenue by offering traditional T1 leased line and private line services, such as: Cable Operators Cable operators connect traditional T1 leased line and private line services over their hybrid fiber coax (HFC) cable networks. Metropolitan Area Networks Metropolitan carriers with IP or Broadband Ethernet access networks deliver traditional leased and private line services. Utilities Utilities generate new revenue by offering traditional T1 leased line and private line services over their fiber or power line networks.

PBX Back Haul
The IP•Tube CEP 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.

Incumbent Carriers
Telcos reduce costs by delivering profitable leased and private line services over their flexible Ethernet infrastructures.

International Toll Bypass
The IP•Tube CEP GT1’s most dramatic cost savings is when it is used for the international interconnections of TDM based telecommunication equipment. The IP•Tube CEP E1 is interoperable with the European TDM standard E1.
