Message-ID: Date: 10 May 89 15:52:39 GMT References: <496@hwee.UUCP> Organization: LCS Expert gang, Rutgers Lines: 25 I recently returned from Trenton Computerfest with lots of nifty junk, including two pieces of communications equipment which I and DEC have completely failed to identify. It's a plain white flat modem-style box, apx. 9x6x1.5, sloped front panel with a little door that opens into two thumbwheel switches and a reset button. On the rear are two DB-25 connectors, male and female marked "COMM" and respectively; two modular jacks, one 4-pin with a handset icon and one 8-pin with a "line" icon [a bar drawn above it!!]; a Molex marked "~24V" for power. No other outside markings on the box. There's a bi-color LED at the right front that indicates status somehow. The thumbwheel switches go from 0 to 9. On the board etch I found "|d|i|g|i|t|a|l", "VT PHONE CONTROLLER", and "50-16478-01" which must be a DEC part number. There are two proms marked "MAIN" and "MNTR". The box has a speaker mounted up under the top. Plugging 24VAC into the two outer pins of the molex causes it to power up, the LED to flash red and green for a while and then go solid green or blinking green, different depending upon where you'd set the thumbwheels. I couldn't get a plugged-in terminal to do anything. What is it??!?! Colorado DEC field service and such has completely failed to find it. _H*
