AR-5127 SIMULATION 8 - 39
2. Display combination
The display conforms to the detection frequency and pattern specified
according to each country information.
The detection signal level conforms to the range set by the soft SW.
The detected table and routines are shared with actual communica-
tions.
Note: Executable only when the FAX is installed.
Operation/procedure
• The pseudo-ringer sound is provided in both of the main speaker
and the external telephone.
• Holding the handset or the external telephone set stops the bell.
Hanging it restarts ringing. This operation is continued until the inter-
ruption command is supplied by pressing the [BACK] key.
• The LCD displays the TEL/LIU status, indicating the HOOK condi-
tion.
• During sending the pseudo-ringer, RBT (Ring Back Tone) is deliv-
ered to the line.
• The bell is ON for 1sec and OFF for 2sec. When off-hooking with the
bell ON, the HOOK detection at pseudo-ringer ringing can be
checked. When off-hooking with the bell OFF, the HOOK detection
before pseudo-ringer ringing can be checked.
Note: Executable only when the FAX is installed.
Operation/procedure
Used to save the SRAM data to the expanded memory and read it.
When reading, however, the current FAX software version and the
header FAX software version are collated together. If they are not iden-
tical, reading cannot be performed.
1. Back-up targets
2. Internal process
1) Used to check if the installed expansion memory is ready to use.
If an expanded memory is available, write the target data of the
SRAM.
2) After completion of writing, management information is written to
the management information block.
3) For the management information, refer to the table below.
However, the FAX program version No. area is written into the data
version no. area (FFF0 - FFFF).
*TEST pattern
Recognized that the card normally reads the next data.
In normal cases, when installation of an expanded memory is detected
after turning ON the power, the expanded memory is cleared. When,
however, there are some SRAM data in the expanded memory, it must
not be cleared. When the ROM data name (FED0 - FFDF) in the man-
agement information of the expanded memory is "REGISTRATION,"
the expanded memory is not cleared.
1) After checking the data in the management information, reading
from the expanded memory and writing into the SRAM are per-
formed.
2) After completion of writing into the SRAM, the expanded memory
is initialized for normal use again.
3) After completion of initializing the expanded memory, the SRAM
RESTORE operation of the simulation is terminated.
1) Before saving, install the expanded memory to be used. (During
power OFF)
2) In the SRAM backup menu (66-53), SRAM BACK UP is selected,
and the process to save SRAM data into the expanded memory is
executed.
3) After completion of saving, turn off the power.
1) Install the expanded memory into which data are written according
to the above procedures. (During power OFF)
2) In the SRAM backup menu (66-53), SRAM RESTORE is selected
to write the SRAM data which was saved into the expanded mem-
ory into the SRAM of the FAX board.
Note: Executable only when the FAX is installed.
