BOSaNOVA e-Twinax Controller 28 device 16 RJ45 connectors

Part Number: 4828
Price: $4976


The BOSaNOVA e-Twinstar Controller includes a built-in unit featuring 8 (or 16) RJ45 sockets. Twinax devices working over CAT5 lines are connected directly to the Controller, saving the cost of an active star hub and eliminating the need for power sources and additional space in the communications closet, as well as the extra set-up and maintenance time.

Ordering Information


The e-Twinax Controller is a hardware and software product that adds the benefits of a LAN to an existing Twinax infrastructure. With the BOSaNOVA e-Twinax Controller, users can access the AS/400 securely over the Internet and use e-mail, Microsoft Networking, and Lotus Notes on any BOS, IBM, or IBM-compatible Twinax card connected to any AS/400 running OS/400 V3R2 or higher. When used as a remote controller, the e-Twinax Controller replaces the SNA/APPC protocol with the TCP/IP protocol, which is easy to support, easy to configure, and routable. The e-Twinax Controller innovative data compression techniques and a faster Twinax line, due to the 5250 Express protocol, combine with the built-in segmentation of Twinax topology for a fast, segmented, and reliable network.

The e-Twinax Controller is the only SNA-free, pure TCP/IP Controller in existence. It moves your twinax network forward in 5 important ways:

  1. Leverage your investment in Twinax by supporting all Twinax display stations and printers (both SCS and IPDS), as well as existing cabling with the e-Twinax Controller.

  2. Increase network speed with pure TCP/IP protocol--all SNA, AnyNet and MPTN traffic is eliminated when used as a remote Controller.

  3. Easy setup and maintainance--supports remote management via a Web browser, saving you valuable technical resources.

  4. Is routable

  5. High uptime and disaster recovery

e-Twinax Controller as an IP Gateway

The e-Twinax Controller connects to the network using a standard network hub, which is attached to the local office via a standard IP router. Ethernet PCs can be connected to the same network hub as the Controller for mixed Ethernet and Twinax infrastructures.

With the TCP/IP drivers loaded on the PC, the user can take full advantage of the WAN, and get:

  • Support for e-Mail
  • Printer and file sharing on the network
  • Ability to access and run Intranet applications
  • Implementation of server-centric computing such as Citrix Metaframe

Turbocharge your IP over Twinax Traffic

The e-Twinax Controller uniquely features IP compression over Twinax, a result of the fact that BOS manufactures both the client IP driver and the controller. Powerful IP compression algorithms compress the data packets that pass across the Twinax network to the controller, enabling compression ratios of on an average of 3:1. Once they reach the controller, the packets are uncompressed and placed on the Ethernet, enabling the system to use the extra bandwidth supported by the Ethernet network. When combined with BOS Express cards, this can mean an increase in throughput of up to 10 times that of a regular Twinax PC card!

Other performance enhancements of the e-Twinax Controller include:

  • Offsetting the extra CPU overhead on the host caused by using IP over Twinax
  • Support for maximum speed of each device on the Twinax line, even in mixed 1MB/2MB environments
  • Connection to the AS/400 using the high performance TN5250e protocol

Sample e-Twinax Controller Configuration for Local Environment, including RAS

Overcome Network Instability and Printing Problems

Dial Backup*

The Dial Backup feature ensures improved uptime for Controllers that are connected to an AS/400 using a LAN connection (via the Internet routers or a separate Frame Relay network). If the LAN connection fails, the Dial Backup provides (via an attached modem) an additional method to connect to the AS/400. Two configurations are available: Always, which provides a simultaneous connection at all times; and "On LAN Failure, which causes the Controller to activate the modem connection only when LAN connectivity failure is detected.

* Optional

Automatic Session Recovery

In the event that a router on a frame-relay network disconnects and then re-connects, users of remote Twinax-attached devices can choose to resume their current session. The e-Twinax Controller can be set to automatically recover the session, within a user-defined time period, ensuring smooth and efficient operations even in cases of network instability.

Customized Object for Specialty Printers

The e-Twinax Controller supports a wide variety of Twinax printers, including label and barcode printers that are often called upon to deal with special printing requirements such as oversized fonts, graphics, and unusual page sizes. A parameter can be set to instruct the host to send a pure data stream through the e-Twinax Controller, allowing it to override the original complex formatting commands with simplified commands that are supported by most printer models, before releasing the job to the destination printer.

PC Remote Access

The e-Twinax Controller supports a 2- or 6-port* Remote Access Server (RAS), providing remote PC users with network access in addition to AS/400 access. Remote users can dial in to the e-Twinax Controller and gain access to the network using the RAS. This RAS includes a firewall for restricting access per user to specific IP devices or ports (e.g. one group of users may be allowed access to the AS/400 for display emulation, but not file transfer). The RAS also automatically logs all remote access activity. The RAS component can use the services of any RADIUS server for authentication, if required.

The e-Twinax Controller can connect mixed remote Twinax and LAN environments using a RAS over a frame relay connection via routers.

E-mail on Dumb Twinax Terminals

Basic e-mail functionality, known as TwinMailTM, is supported on dumb Twinax terminals. In addition to sending and receiving e-mail, TwinMail includes a personal address book that can be organized according to user-defined preferences.

* Optional

Configuration and Maintenance with Ease

The e-Twinax Controller is managed via a standard Web browser, enabling centralized management of all of the units from anywhere on the network, or via a modem dialed in to the RAS. Configuration can also be done using a dumb terminal attached to any of the ports. The controller software can also be updated, including expansion of supported devices and features functions, over the network or via dial-in. Terminals, PCs or printers can be added to the controller very simply using a plug-and-play feature in Auto mode. The device name can be changed at any time, without restarting the controller. The e-Twinax controller also verifies the host connection, including which PTFs are installed for each OS version.

Support for APPC Connectivity

Since the e-Twinax Controller is an IP device that communicates with the AS/400 over a LAN connection, APPC can be supported using Anynet. The PC Twinax user simply installs the IP driver, then reconfigures the APPC software to connect over TCP/IP. For PCs using Client/Server software that requires E32APPC (the IBM-defined standard for router interfaces) the router must be configured to use Anynet. This procedure will restore the APPC connectivity option.

Secure Low Cost Connection Using the Internet

The e-Twinax Controller can be connected to the AS/400 via the Internet, saving you a fortune in leased line expenses. The e-Twinax Controller requirements are minimal: at the local site you need a fixed connection to the Internet and BOS’ Java SECURIT-e ServerTM, which can be run on the AS/400, and any PC or MiniComputer with a Windows- or Unix-based operating system. At the remote site you need a connection to the Internet, either via a dial up account or using a leased line to a local ISP. 5250 traffic, encrypted via industry-standard algorithms, flows from the controller to the Java-based server, then the data is deciphered and sent to the AS/400. Using this connection method the customer can save thousands of dollars a year on long-distance leased line costs. The e-Twinax Controller can initiate the dial-up to the Internet when the first user tries to access the AS/400. It also supports numerous, simultaneous connections to multiple ISPs, allowing increased bandwidth as well as a built-in fallback when required.

The BOSaNOVA e-twinax allows a secure connection via the Internet using modem(s) for a mixed Twinax and LAN environment.
