An allotter, particularly one adapted to be used in a telephone system, is formed of a plurality of stages, each of which is associated with a prescribed type of utilization device, such as a junctor, tone receiver, register, etc. for which a request for access may be effected. Each allotter stage includes a pair of flip-flops for indicating whether the device associated with that stage is free and if it is the last device in a group which has been selected for allotment. The stages may be connected in groups for either homing or non-homing type of operation.
