Description
This board contains software and hardware controlling the whole system. The board houses ASICs developed by STENTOFON: the MBI (Master Bus Interface) and SBI (Slave Bus Interface). It plugs into any of positions 20-25, recommended position is 25. The software on the board supports board monitoring which reports errors on all the other boards in the system. The reports can be printed out by connecting a printer to one of the serial ports. In addition there is the possibility to log technical alarms. All signals for external equipment is run to a connection board mounted on the connection field of the exchange.
