Hello all.
I bought this gem for 8 EUR.
About the only thing that comes up on google is the auction where I bough this. It's missing the buttons on the front, also there was no power supply but the PCB text says 20V (AC) and using a US Robotics 20vAC PSU (from a much later modem) does work.
What does the text "2x300" mean? The V21 spec says the transfer speed is 300 baud, so does the RS232 side run at 600 baud then?
So far I haven't been able to get anything out of the RS232 port (which I presumed to use a standard pintout, which I of course can't know for sure). I am guessing that this predates any Hayes compatibility, so this doesn't have any AT like commands at all? Also is this a manual dial modem, ie. I need to plug in a phone and use that to dial the number and then press Data on the modem perhaps?
How does one operate a non-Hayes modem? Did these have any commands on the RS232 side or did you dial manually, and would the modem itself then detect appropriate carrier and signal and then just open the port and dump the de-chiphered signal there?
I attempted to plug this in to my VoIP box with either a modem or a dial-touch phone on the other line, using a config where I can dial from one port into the other. When dialing the ITT (from a phone or from a newer 56k modem) I can hear that the line delay clicking in and out as if it's switching itself into the line so it detects the incoming call.
A phone connected to the ITTs phone output is completely silent (perhaps this is meant for a older pulse-dial phone? But shouldn't I still have the line noise on the newer phone?).
I am not sure if I can do anything with it (also the whole above is just my thinking out loud wondering), but it's cute little device anyway
