Telecom Database General Knowledge

Database in Telephone Exchange is nothing but the set of Rules/Protocols book for the Telephone exchange processor to follow for each subscriber input to the exchange.
The input to a basic telephone exchange is digits dialed by the subscriber for the need of connection to the dialed number to make a voice call.

In the telephone exchange all the records will be created in a normal database TABLE format. Let us take a example of a Landline Telephone exchange and the database model in that.
