Compatibility

The four-wire interface provides compatibility with existing standard station range from STENTOFON with the exception of TouchLine display stations produced earlier than March 1995. These stations are no longer compatible due to reduction on the display signal output from the exchange. TouchLine display stations produced after March 1995 are labeled version 1.1 and are fully compatible with the AlphaCom exchange.
