| Ethernet Switch OPTION - SWITCH The IP•Tube G4 E1 is available with a five port 10/100 Ethernet QoS switch integrating a high-performance switching fabric with four priority queues. Advanced features include 802.1p/IPv4/IPv6 traffic classification, full IEEE 802.1Q VLAN, RMON, SNMP, Port Monitoring and Layer 2 firewall. QoS determined by destination MAC address, port ID, IEEE 802.1p and multimedia traffic tags, IPv4 Type of Service (TOS), and Differentiated Services (DiffServ).

Virtual Private Network Support

Lossless Data Compression Option The IP•Tube G4 E1 detects idle/redundant data within each DS0 resulting in as much as 56 to 1 bandwidth savings. E1 over IP bandwidth is not consumed by silent or redundant circuits. Management of the IP•Tube G4 E1 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
|
SuperTube Option
The typical way to extend E1 circuits across packet networks is for each E1 to be encapsulated into individual IP packet streams. The SuperTube Sized IP•Tube 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 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. |

GPSDO Stratum 1 Clock OPTION -GPSDOThe GPSDO Option receives GPS satellite timing signals to control an onboard oscillator providing from a E1 Stratum 1 reference clock. The GPSDO Option utilizes a mixed-signal phase lock loop GPS driven frequency module to generate extremely accurate 2.048MHz E1 references clocks that are frequency locked to the Global Stratum 1 source. The Stratum 1 clock is the basis for all telecom voice and data interfaces, required to assure proper synchronization of signals and call quality.

| Pay-As-You-Grow Field Upgrades The IP•Tube G4 E1 is designed for Pay-As-You-Go growth from 1 E1 thru 4 E1s per IP•Tube G4 E1. Customers can elect to economize initial network installations, by purchasing their IP•Tube G4 E1 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 IP•Tube G4 E1 can be upgraded to Lossless Data Compression with a simple software-based license key installation. If upon installation, you determine that your IP•Tube G4 E1s are best deployed with Lossless Data Compression, you're still in business with the per port field upgrade! |
Applications
E1 Over IP Ethernet Benefits
| |||||||||
E1 Private Line Services over IP | |||||||||
| Multi-Site Enterprises, Cellular Service Providers, Education Districts, Universities, National, State and Local Government, and Municipalities incur significant recurring monthly costs for rigid-bandwidth leased lines used only for the interconnection of PBXs and Telecom switches. The IP•Tube G4 E1 provides organizations with the ability to interconnect their existing phone systems over flexible bandwidth lines that are used to carry data, voice, and video. The Voice Only Leased Line Toll charges assessed by long distance and local carriers are eliminated or dramatically reduced by transporting voice traffic across LANs and WANs.

LANs
| |||||||||
| WANs Wide Area Networks that have sufficient bandwidth and Quality of Service provisioning result in very significant cost savings especially for Multinational Corporations. The IP•Tube G4E1-Cwith loss less 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 samples. | |||||||||
E1 Over Wireless Ethernet | |||||||||
Interconnection of E1 based data communication systems over wireless as a primary or back up connection is a major application of the IP•Tube. For over eight years the IP•Tube has proven itself around the world as an effective method for using Commercial Off the Shelf Wireless Ethernet Bridges to interconnect E1 circuits. The IP•Tube Assured Delivery Protocol has the sophistication required for solid performance across a wide range of wireless connections. The use of parallel Wireless Ethernet links minimizes the latency and Radio’s packet processing requirement.
| |||||||||
| Cellular Base Station Backhaul | |||||||||
IP•Tube G4 E1s provide transparent interconnection of Base Stations, Base Station Controllers and Mobile Switching Centers over IP Ethernet packet-switched networks. Cellular service providers save substantially by converting to a packet switch network. The Lossless Data compression option, which is especially well suited to Cellular communication links, minimizes the bandwidth required to interconnect. Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit based TDM leased lines. The Loss Less Data compression option provides a 56 to 1 compression, which minimizes the bandwidth required to interconnect, is especially well suited to Cellular communication links. Engage's first deployment of the IPTubeE1, in the Spring of 2000, was for an international interconnection of a Cellular Base Station to a Base Station Controller. The SuperTube Option reduces the overhead and packet frequency while lowering latency which makes cell backhaul a possibility over Wired and Wireless connections. Note: The Ethernet Switch Option has the sophistication to support Ethernet Native Base Station applications with QOS and rate limiting.
