Call progress monitor for line powered
telephone sets
TEA1083; TEA1083A
APPLICATION INFORMATION
An application of the TEA1083/83A, in conjunction with a
member of the TEA1060 family, is illustrated in figure 11.
The TEA1083/83A is used for call progress monitoring
during on-hook dialling. The dialling facilities are
performed by a microcontroller (e.g. PCD3344,
PCD3349).
Only the most important components have been shown.
For detailed information refer to a data sheet of the
TEA1060 family.
The electronic hook switch can be replaced by a
mechanical system (hook switch) with a hold/release
function which is intended for on-hook dialling.
