Claim:
1. A communication apparatus comprising: a modem processing unit configured to perform facsimile communication; a modulated digital signal storing unit configured to store into a storage unit a first pulse code modulated (PCM) digital signal that is modulated by said modem processing unit, for transmission to an opposite-side apparatus in the facsimile communication without converting the first PCM digital signal to a first analog signal; a network interface control unit configured to transmit the stored first PCM digital signal to the opposite-side apparatus without converting the first PCM digital signal to the first analog signal; and a demodulated digital signal storing unit configured to store into the storage unit a second digital signal that is obtained by demodulating a received second PCM digital signal received from the opposite-side apparatus in the facsimile communication by said modem processing unit, wherein the second PCM digital signal is received from the opposite-side apparatus without conversion from a second analog signal.
