Subscriber Line Board
This board contains circuitry for 6 subscriber connections and one measurement channel for voice switching control. It plugs into any position 1 – 23.
The board provides 6 remote control outputs that are software-controlled. The line monitoring reports errors on all subscriber lines.
The board can be plugged in/out while the exchange is running. A hot plug-in cable is needed for this purpose. The cable is included in the cable set for the exchange.
A four-wire interface provides compatibility with existing standard station range from Vingtor-Stentofon with the exception of TouchLine display stations produced earlier than March1995. 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.
All signals for external equipment is run to a connection board mounted on the connection field of the exchange.
