SM-56 Security Dial-up Modem
Download the Manual
The SM-56 is an industrial rated high security dial-in/out modem containing one RS-232 serial port, one telephone line V.92 modem port, and one 100BaseT ethernet port. It may be used as any other simple modem or configured for high security uses. The RS-232 serial port operates at asynchronous speeds from 1200 bps to 115.2 Kbps.
There are several high security modes, making this security modem very versatile:
If the modem detects a denial of service attack, an SOS feature will stop answering dial-in calls temporarily and report to a dial-in pre-configured number such as a numeric pager.
Call attempts, call statistics, and management functions are always logged. The 10/100 ethernet port shares the dial-out modem for locally connected LAN clients that don't have a directly connected modem. This features is accessed with the simple telnet program available for all PC workstations. It may also be used in reverse as a telnet client for the dial-in user after authentication.
The modem is configured using proprietary AT commands with a telnet connection to the 100BaseT port or directly connected to the RS-232 serial port. A validated administrator must be signed into the modem to perform any management steps remotely.
The SM-56 security modem is ideally suited for Critical Infrastructure Protection regulations propagated by the NERC and some FIPS standards. It may be used to meet NERC Cyber Security Standards CIP-005-2 and CIP-005-1 to secure the electronic security perimeter (CPS) around all critical cyber assets.
