Abstract

PURPOSE:To make handling of collect-call or the like easy, by separating public telephone sets connected to the same telephone line into public exclusive outgoing telephone sets and incoming call telephone sets for manager, and disabling the response of the outgoing exclusive telephone sets in case of an incoming call. CONSTITUTION:Since line terminals L1, L2 are connected to a norally outgoing call exclusive telephone set TEL1 with contacts r<0>, r<1> of a relay R which is of AC sensing type and has holding mechanism, the outgoing calls can freely be made by the TEL1. When a callout signal is incoming, it is applied to a bell BL in the same case as an incoming telephone set TEL2 for ringing, then a hook switch HS is switched by off-hook of the TEL2, the callout signal is given to the relay R, which is activated, and the contacts r<0>, r<1> are switched and call is made by the TEL2. The relay R is self-held and it is restored with on-hook of the TEL2.
