PURPOSE:To prevent defect in a coin store by grasping surely the amount of the coin stored in a public telephone set at the central exchange office side. CONSTITUTION:When the called party responds by the calling of the public telephone set 1, a coin store pulse M/M is transmitted to a line circuit 2 with the command of a central processing unit 5. When the central processing unit 5 judges the M/M signal reception, the M/M integrating processing and store (coin store and link) are performed. At every store as above, whether or not overflow is checked, and if overflow exists, it is typed out on the typewriter 7. When it is judged as KEY information, the content of store up to now is left as the ticket information in another memory area together with a data, and the store counter memory is cleared. This ticket information is used to check the content of the money collection. |
