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.
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-Twin@x 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-Twin@x 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-Twin@x 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.
e-TwinSt@r Series Eliminates Need for Active Star Hubs
The e-TwinSt@r Series 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.
E-mail on Dumb Twinax Terminals
*
Basic e-mail functionality, known as TwinMail, 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.
PC Remote Access
The e-Twin@x 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-Twin@x 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.
e-Twin@x Controller as an IP Gateway
The e-Twin@x 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; access to Internet applications; and support for Citrix Metaframe.
Configuration and Maintenance with Ease
The e-Twin@x Controller is managed via a standard Web browser, which enables all of the units to be managed from a
central point 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 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 Controller also verifies the host connection, including
which PTFs are installed for each OS version.

Secure, Reliable, Low Cost Connection using the Internet
When the traditional SDLC connection is replaced with a Wide Area Network (WAN) connection using TCP/IP, the e-Twin@x
Controller can be used to maintain legacy Twinax devices (such as high-speed printers and dumb terminals) at your remote
sites. In this configuration, all the devices will appear on the AS/400 as TN5250 devices, and all PC devices can connect
to the AS/400 either by using dumb terminal emulation or by installing the e-Twin@x version of BOSâNOVA TCP/IP or IBM
TCP/IP drivers to connect to the AS/400 over TCP/IP.
The e-Twin@x Controller can be connected to the AS/400 via the Internet, saving you a fortune in leased line expenses.
Requirements are minimal:
Local site: a fixed connection to the Internet and BOS' Java-based SECURIT-e Server™, which can be run on the
AS/400, and any PC or Mini Computer with a Windows, Unix-based or Linux operating system.
Remote site: 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, where the data
is deciphered and sent to the AS/400. The e-Twin@x Controller can initiate the dial-up to the Internet when the first user
tries to access the AS/400. It also supports two parallel connections to two different ISPs, allowing increased bandwidth,
speed and reliability.
