ABSTRACT:
A method and apparatus is provided wherein the total elapsed time for a series of outgoing calls on a plurality of call lines of a telephone is accumulated for each of those lines by a plurality of clocks and switches operating in a monitoring circuit for the output lines. An operator of the telephone may note the accumulated time on each line so as not to exceed an allotted time as is used in different regions of wide area telephone services (WATS). When the timing apparatus is used with a key telephone, the timers are controlled by individual reed switches, each of which is associated with a respective key switch and activated by a magnet attached to said key switch.
