BlackTube E1 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 BlackTube E1 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

Dual LAN Interfaces

All BlackTube E1 models  ship with dual 10/100BaseT Ethernet LAN ports. The dual Ethernet interfaces provide for:

• The 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 BlackTube E1 uses the Type of Service byte in the IP packets or 802.1p/q mac levels for prioritization of the encapsulated E1 frames. QOS is used to ensure that the  real time Circuit data from the BlackTube E1 is ensured high priority.

Full E1 Connection Across Two ADSL Lines

The BlackTube E1's two Ethernet interfaces are able to utilize two ADSL Ethernet Modems, that have opposite high speed direction, to transport an E1's symmetrical bandwidth.

Virtual Private Network Support

Interconnecting the BlackTube E1 through a Virtual Private Network with sufficient real time committed information rate ensures that the required quality of service is provisioned. The second Ethernet interface provides a management port. Each LAN interface features independent IP network configurations.

BlackTube E1 Options

DS0 Time Slot Multiplexer OPTION -MUX

The BlackTube E1-MUX maps DSOs from a central site to as many as 31 remote locations via an IP/Ethernet connection. Get maximum use of expensive DS1 interfaces on PBX, Channel equipment and datacom gear. Also provides Virtual DACS Over IP capability. Mesh DS0s one-to-many or many-to-many.

E1 Switch OPTION -SWT 

The E1 Switch Option enables the E1 Port 1 interface to be manually switched between a E1 circuit connected to E1 Port 2 or to E1 Over IP packets connected with the remote IP Tube.

E1 Link Protector OPTION -LPT 

The E1 Link Protector provides an automatic back up for E1 circuits with E1 Over IP connecting via Wireless Ethernet, Gigabit Ethernet, IP Satellite Services, and xDSL.

Lossless Data Compression OPTION -C

The BlackTube E1-C continuously detects idle and redundant data within each E1 Voice circuit resulting in as much as a 40 to 1 bandwidth savings. TDM over IP WAN bandwidth is not consumed by silent or redundant circuits.

Alternator Load Balancing OPTION -ALT 

The BlackTube E1-ALT Alternator option alternatively sends the IP packetized E1 frames on LAN 1 and LAN 2. The Alternator option enables fractional and full E1 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.

Rate Limiter OPTION -RLM

The BlackTube 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 BlackTube 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 BlackTube 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.

Field Upgrade benefits are extended to our Industry-Best Lossless Data Compression. Just as E1 ports are field upgrade able, so is Lossless Data Compression. At any time, each E1 port on the BlackTube E1 can be upgraded to Lossless Data Compression with a simple software-based license key installation. If you determine that your BlackTube E1 is best deployed with Loss less Data Compression, you're still in business with the per port field upgrade!

Rack Mount Kit

The BlackTube family is ready for your most demanding central office or data center environments. With the Rack Mount Kit, BlackTube products are easily installed in 19" and 23" racks. Easy access to both front and rear sides facilitates technician maintenance procedures.

Flexible Encrypted Serial Data Extensions over IP Packet or MPLS Networks

The BlackTube SERRS232 converts RS232 serial data connections into AES encrypted IP packets, securely extending the serial data over very cost effective Ethernet or MPLS based LAN/WAN/MAN wired and wireless networks. Synchronous, Asynchronous, Isochronous or HDLC serial data is encrypted then encapsulated into IP packets. This facilitates the packet interconnection of Serial: Bulk Encryptors (KIV7/OMNI), Data Terminals, Data Acquisition, SCADA RTUs....

Encrypted Serial over IP

Integrating encryption into the Engage's serial to packet converter means serial control and monitoring traffic is never “in the clear” on the packet network. Additionally, since encryption is done at the source prior to transport over the primary or redundant packet networks, the expensive and complexity of external in line Encryptors is eliminated.

Layer 1 with Isochronous

In Layer 1 operating mode every bit is encapsulated into an IP packet. The size and frequency of the IP packets can be set with data bit rates from 75 bits to 256 kilobits per second. Isochronous serial protocols, such as Conitel, are transported synchronously to maintain message timing alignment. A configured number of incoming packets are buffered in order to compensate for the peak packet delivery jitter introduced by the network.

Asynchrous over IP

Asynchronous characters from the RS232 interface with 5 to 8 data bits, baud rates from 1.2 to 38.4 kilobits, 1 or 2 stop bits that are with or without parity are efficiently encapsulated into IP packets. The encapsulation supports block mode transfers to minimize the bandwidth required. Additionally the latency is controlled by setting the Tube Bytes per packet.

HDLC over IP

In Layer 2 operating mode HDLC Data frames, such as those used by Wide Area Networking protocols PPP and Frame Relay, are transported within IP packets as HDLC over IP. The Serial to Packet conversion only occurs when HDLC frames are active.
