20221210_172901.jpg 20221210_172914.jpg 20221210_172920.jpg

This is a rather high-end ISDN terminal adapter from 1995. It combines an ISDN terminal adapter with a built-in V.34 capable analog modem, so both ISDN data calls as well as analog modem calls are possible.

Manual
Supply Voltage 9V AC
Power Consumption ~5.9W
RS232 Connector DB25
Line Connector RJ-11 (unusual for ISDN)

Hardware

The hardware design is a two-layer circhit board design:
  • the bottom circuit hoststhe pure ISDN TA
  • the daughterboard contains the V.34 analog modem using a Rockwell L39W/U + RCV288DPi chipset
