hi, does using caller id affects broadband, and do we have to enable it from exchange.
 
caller id for the phone has to be enabled at the Exchange . And
pls see this topic for the other part of your query .
 
he knows that thread as he posted there just day b4
 
but i have not got answer, and the post itself was confusing, and after postingon that post i have not see it again, cli , was confusing term,.
 
^ caller ID for the phone has no relation with the broadband speed .
 
I'm tryin to use the caller identification function in a project. For this i need to read the caller id of the incoming call using a microcontroller. So i need the encoding technique and the code word for the caller id used in india.... could some1 help me out???
 

hmm thnx for tht, have read n searched a lot regardin dtmf n fsk encoding.... afaik, bsnl sends the caller id encoded using dtmf signal... but how its sent over the line, i mean the line voltages of the signals, and their duration etc. is wht i aint able to find... i'd also wanted to kno how the word is encoded, as in if any start bits or nething are transmitted. the whole project is to be implemented using a microcontroller/peripheral electronics. thts why i need these details.
