Remedy 3 for Echo (on reception side; change made to the time during which low-
speed signals are ignored after CFR transmission)
Set ‘1’ to bit 4 of SW04 of #1 SSSW (service soft switch) so that the time during which
low-speed signals are ignored after CFR transmission will be longer (instead of 700 msec,
it will be 1500 msec).
8.Echo Protect Tone: SW03 bit 1 of Service Soft Switch #1 SSSW
• Add an echo protect tone to the V.29 modem signal for transmission:
When SW03 bit 1 is set to ‘1’, an echo protect tone will be added to high-speed trans-
mission V.29 (at 9600 or 7200 bps) for transmission.
9.Number of Final Flag Sequences: SW04 bit 2 of Service Soft Switch #1 SSSW
• Increase the number of final flag sequences:
When SW04 bit 2 is set to ‘1’, the number of final flag sequences will be increased
from 1 to 2 for a procedure signal (transmitted at 300 bps).
10. Subaddress
A subaddress is used to indicate the location of a memory box in the other party (e.g.,
confidential mailbox, polling box), and it consists of 20 or fewer characters (numerals, *,
#, space). As log as the other party complies with the International Standards of ITU-T,
the machine can communicate with it by means of subaddresses.
At times, an ID number (referred to as a “password”) is used to restrict access to a loca-
tion indicated by a subaddress.
With some models, polling based on subaddresses is called “selective polling”, and a
subaddress used at time of polling is called a “selective polling address”.
11. Password
A password used by a Canon facsimile machine may be any of the following:
Password for Subaddress Communications:
This is an ID number used for a subaddress communication and, as in the case of a
subaddress, it consists of 20 or fewer characters (numerals, *, #, space).
Communication Password:
This is an ID number used for a password communication. Some models use 4 decimal
characters (0000 through 9999), while some use 3 decimal characters (000 through 255).
Memo
Password Used When Making Settings:
A password may also be used for memory lock Rx, call restriction, and
other functions. Such a password consists of 4 decimal characters (0000
through 9999), and it is important to remember that these passwords are
used inside the machine and are not intended for communication proce-
dures.
