General functions of this circuit are as follows:
1)
Generates and detects signals to be exchanged with a telephone exchange or
network in Phases A and E defined by ITU T.30.
•
Loop formation for call origination
•
Line current detection (see note 1) before call origination
•
Dial tone detection (see note 1)
•
Generation of dial pulses (see note 2)
•
Busy tone detection (see note 1)
•
Ringing signal detection
2)
Sends various data and signals from the R51 board to the telephone line after
amplification.
•
Picture data/Protocol/Tonal signals/PB tone, etc.
3)
Sends the following signals received from the line to the R51 board as data
after amplification.
•
Picture data/Protocol/Tonal signals, etc.
Note 1: This procedure may be omitted depending on the dial parameters.
Note 2: MF (Multi-frequency) tone is generated by the modem and transferred
to the telephone line via the NCU board.
