Abstract
Apparatus for an improved ISDN terminal adapter (5) and accompanying methods for use therein. The adapter provides automatic ISDN switch detection, automatic SPID configuration, baud rate unblocking and automatic data compression. Specifically, with respect to baud rate unblocking, the adapter detects instances of baud rate blocking, through excessive communication errors for a known input, and forces the adapter to relinquish its high speed setting and automatically return to autobaud operation but at a lower maximum speed.
