'Turn power off before inserting or removing boards |
All intercom stations are connected by means of pluggable screw terminals on the exchange back-plane. The RCO outputs 1-6 are associated with the board in pos. 1, and RCO 7-12 with the board in pos. 2.

Physical numbers 5 and 6 are by default used as inputs for Audio Program distribution, but can alternatively be used for intercom stations. See related article: Physical number 5 and 6 (AlphaCom E7) |
Cabling
Desktop stations are connected to the line on RJ45 wall sockets.
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.
