The Lossless Data Compression option can be combined with the Alternator option to minimize the bandwidth required from the alternative paths.
Rate Limiter Option -RLM
The Black•Tube E1-RLM Rate Limiter option limits the WAN bandwidth utilized by the LAN1 to LAN2 bridge. Rate Limiting the traffic enables the reservation of the WAN bandwidth for time the sensitive E1 Over IP real time connections. Great for Wireless WAN E1 applications. Rate Governing is only applied in the direction to the WAN to minimize latency. The data rate governor utilizes Time Division Multiplexing based clocking to provide for Nx64, NxE1 and NxFT3 bandwidth regulation that is configured from 64 kilobits up to 45Mbits.
Protector Option -PRO
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 Black•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 Black•Tube E1s are designed for Pay-As-You-Go growth from 1 E1 to 3 E1s. Customers can elect to economize initial installations, buy purchasing a single active E1 port and enable additional E1 Ports via a software-based license key.

Applications
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 BlackTube E1 provides organizations with the ability to securely 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
The most compelling option for the interconnection of E1 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 result in very significant cost savings especially for Multinational corporations. The BlackTube E1-C 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 samples.
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 E1 based communication equipment is made possible with the IP Tube’s E1 Over Ethernet capability.
UnEncrypted interconnection of PBX connections across Wireless is able to be eavesdropped with Shareware Packet Capture programs. The BlackTube E1 ensures that private branch connections across wireless networks remain private.
Cellular Base Station Backhaul
BlackTube E1s are used to provide transparent interconnection of the Base Stations, Base Station Controllers and Mobile Switching Centers over IP Ethernet packet-switched networks.
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 40 to 1 compression, which minimizes the bandwidth required to interconnect, is especially well suited to Cellular communication links.
Engage's first product deployment, in the Spring of 2000, was for an international interconnection of a Cellular Base Station to a Base Station Controller.
