Welcome back again with the concepts of a Digital Telephone Set. If you are seriously looking for the Digital Telephone Set, This is the Right Place for you. Here we are describing about the Digital Telephone Set Properly. Remember that the Information we are providing in below, that is fully Practical Based. Just read the full Information and get an idea on the Latest Digital Telephone Set and its Working process, Specification.
Telephone exchange lines connecting the power supply 40 V.D.C to 60 V.D.C are set for each Telephone. This Voltage to Operate the Telephone. When the handset to the base unit is installed, then the DC voltage is applied to the ringer section. There are too many building options available on a Telephone Set. Digital telephone system mainly build consists of the following components:
(i) In-line Protector Section. (ii) Ringer Section. (iii) Voltage Dropper Section. (iv) Sound or Speech Section. (v) Keyboard or Matrix Section and (vi) Dialer Section.
That is the main Section of a Digital Telephone Set. Mainly a Digital Telephone works with the above elements combination.
In-line Protector Section: It comes with two sets of exchange line Telephone. It is associated with the exchange of any two telephone sets are used for audio signal transmission and Reception.
DC voltage electronic devices to operate the Structurally. The circuit is made of a protector, which will supply voltage circuit Basic structurally. A bridge rectifier circuit is used as the protector circuit. It provides positive polarity output for any input structurally. Ringer through the polarity of the output circuit is protected. Coming from the exchanges between the two by adding the line voltage stabilization is a VDR.
Ringer Section: This Section Process 20Hz Signal from Telephone line and builds ring signal to provide to buzzer. All the processing system of ringer section controlled by an IC (Intergraded Circuit). A Single Capacitor and on-hook/off-hook/Ringer Switch provide in Ringer Switch. Capacitor help to Stop DC Current and help to g AC Current. When a call comes from Telephone, Then the Exchange Carried 2o Hz Ringer Signal to the Set.
In conclusion, We hope that you have gained about the Digital Telephone Set and its Working Process. If you have any question, just Ask to us via the Comment box or use our Contact us form to send personal Message. Thank you for being with us.
