REMOTE RS-232 PORT SELECTION SWITCH Provides Highly Secure Access and Easy RS-232 Port Selection |

DESCRIPTION
This unique concept is accomplished through the interaction of a unique matchbox
sized hardware KEY connected to the analog side of the caller's modem and the
232-PSS. The authentication handshakes and port selection occur within one
second of the receiving modem going off hook.
Inbound calls without the proper Secure Access KEY are simply aborted. There are over
a billion handshake combinations that change with each call. The port selection
(1-8) is made via a manual rotary switch that is also on the caller's KEY.
The authorization and setup occur very quickly; long before the modems are trained.
There are no passwords or cumbersome software switching codes to enter. In fact,
a PC is not even required. The subsequent data is transferred transparently;
unlike software controlled switches where certain bit patterns can make the
switches "burp" or even switch ports.
The KEYs are programmed from the 232-PSS (Also see Remote
Programming), no PC is required. They may also be programmed
selectively so that only certain KEYs allow access to certain ports, or to
broadcast to all ports.
Since the 232-PSS initiates its operation on the analog side of the operative
modems, the system is completely hardware and software independent. Once the
automatic setup is completed, all of the asynchronous RS-232 signals are linked
transparently between the modem and the DTE; except for "ring". No data rate
setup is required on the 232-PSS and there is no buffering or band pass
limitation. Outbound calls through the 232-PSS are also isolated and can be
placed from any port transparently, or not allowed.
The 232-PSS was primarily designed for remote maintenance applications, but it
can be used for any remotely controlled switching requirement or even used as a
secure broadcast switch to multiple RS-232 devices, such as printers.
Maintenance ports are becoming a preferred path of entry for hackers. As the
number of maintenance ports increase on commonly available hardware operating
with well-documented mainstream operating systems, security is becoming an
urgent issue.
The system is deceptively simple to use for the high degree of security and type
of switching options that it provides.
REMOTE PROGRAMMING (Programmer Required)
Also see the Modem Router Switch (MRS). It provides a
similar function to the 232-PSS, except that the switched ports are analog modem
ports and not RS-232 ports.
