Children's phone "DT-1".
Everything else not included in the sectionsInterphone devicesChildren's telephone "DT-1" was produced presumably since 1976 by the Perm Telephone Plant. The phone is designed for wired two-way telephone communication between two subscribers. When you pick up the handset of one telephone and rotate the dialer, a call to the second subscriber is made by sounding a buzzer. When the second subscriber picks up the handset, the conversation can be carried out as on a regular telephone.
