Tone and pulse dialling, tone and pulse telephone set
Two types of telephones are mainly used in public networks - a rather obsolete
pulse dialling telephone and a modern tone dialling telephone (most tone phones
feature both pulse and tone dialling, a switch is used for selection).
The 2N
NETSTAR PBX works with both telephone types, yet with lower comfort in the
pulse dialling ones. The control functions may be different for some services and so
find what type of telephone you are currently using. We recommend you to use tone
dialling phones to get more comfort.
Bundle
