Tel Electronics Inn-Form XL
This device is a Tel Electronics Inn-Form XL which interfaced with a PBX system using a serial data connection to process SMDR (phone switch call accounting) data. This kind of unit retails new for $1000s even today, if you could even find someone to buy it. It is a relic of a PBX system that was shut off long ago. The parallel port connection seen here is a printer interface.
