TELEPHONE
MUSICAL HOLD ON
A very smart circuit for having music in the telephone,
when you put the caller in “hold”. It is a useful
alternative solution for telephone sets that don’t have
this option.The construction is based on an IC that
generates a known melody. It also gives you the ability
to record your own melody from a tape player or CD.
There is no need for power supply as it is connected in
parallel with the phone line.
TELEPHONE IN USE INDICATION
A simple, useful and cheap solution with no need for
external power supply, that shows you if the line is
busy. It can also show incoming calls without ringing.
Useful for old type telephones, but also for units put in
parallel to show if someone else is using the line.
