BASIC OF TELEPHONE
Here, we have described an example (number of dial pulses = N) where the
number of dial pulses is the same as the dialed number (N). However, in
some countries, the number of dial pulses is sometimes different as fol-
lows:
The number of dial pulses is the dialed number (N) + 1
The number of dial pulses is the dialed number (N) - 1

Bell (Speaker)
The calling identification (CI) signal from the exchange for notifying that
you have an incoming call is converted to the ring tone and is output.
Recently, a speaker or buzzer is used instead of the bell.
