Signal Identification Signal Format Function
Training 1 ——————— A fixed pattern is transmitted to the
receiving
at a speed (2400 to 14400 bps) designated
by
DCS, and the receiving side optimizes the
automatic equalizer, etc., according to this
signal.
TCF
(Training Check)
——————— Sends 0 continuously for 1.5 seconds at the
same
speed as the training signal.
CFR
(Confirmation to
Receive)
X0100001 Notifies the sending side that TCF has been
properly received. If TCF is not properly
received,
FTT (Failure To Train) X0100010 is relayed
to
sender. The sender then reduces the
transmission speed by one stage and
initiates
training once again.
Training 2 ——————— Used for reconfirming the receiving side
like
training 1.
Image Signal Refer to the next page. ———————
RTC
(Return to Control)
——————— Sends 12 bits (0...01 × 6 times) to the
receiver
the same speed as the image signal and
notifies
completion of transmission of the first
sheet.
EOP
(End of Procedure)
X1110100 End of one communication
MCF
(Message
Confirmation)
X0110001 End of 1 page reception
DCN
(Disconnect)
X1011111 Phase E starts.
MPS
(Multi-Page Signal)
X1110010 Completion of transmission of 1 page. If
there
still more documents to be sent, they are
output
instead of EOP. After MCF reception, the
sender
transmits an image signal of the second
sheet.
PRI-EOP
(Procedural Interrupt-
EOP)
X1111100 If there is an operator call from the sender,
it
output after RTC.
PIP
(Procedural Interrupt
Positive)
X0110101 This is output when an operator call is
received.
B. Redundancy Compression Process Coding Mode / This unit
uses one-dimensional MH format.
