HOTEL PBX ELECTRONIC MESSAGE BILLING ARRANGEMENT Abstract of the Disclosure An arrangement for electronically recording and displaying charges for calls made from station lines of a hotel or motel PBX is disclosed which eliminates the use of the prior art banks of electromechanical message registers. An electronic memory unit is accessed when a call is made and the number of the calling station is entered into a trunk memory word. When the central office sends message charging pulses to the PBX, the trunk word is accessed and the station number is read out. The station number then addresses the memory and the message count accruing in a memory byte assigned to the station word is incremented. Thereafter, the hotel clerk by dialing a prefix code and the station line number may obtain a display of the message count accruing for the station; the system generates a pseudo trunk number and is thereby able to reuse most of the same memory access and output register circuitry that was used to store the line number and to increment the message count.
