DIALLING IN PULSE DIALLING MODE
(
MIXED
MODE DIALLING
)
If the controller is set to the pulse dial mode (pin PD/DTMF
is LOW), activation of keys TONE,
or # changes the
dialling mode to DTMF.
Its entry is stored in the redial register and it generates
automatically an access pause, after which the following
digits are transmitted in the DTMF mode.
The digits entered after keys TONE,
or # are not
transmitted in the redial mode. The TONE key is never
transmitted in the redial mode.
The TONE key is never transmitted, whether
or # are
transmitted depends on the selected option.
A second touch of the TONE key is ignored. The
or #
keys pressed after a switch over to DTMF dialling are all
transmitted.
If the controller is initially set to the DTMF mode (pin
PD/DTMF is HIGH), activation of TONE is ignored and the
or # are stored in the redial register and transmitted in
DTMF mode.

ARTH FUNCTION
Whether the Flash or Earth function is activated by the
FLASH key is programmed in the EEPROM.
If the FLASH function is selected a calibrated FLASH pulse
(recall register) is generated on the DP/FL output and the
MUTE output is active.
The calibrated FLASH time is programmed for 100, 115,
270 or 600 ms in EEPROM.
If the EARTH (‘Connect a/b to earth’) function is selected,
the EARTH output becomes HIGH and the MUTE output
is active. The time of earth connection is 400 ms.
When the FLASH key is pressed the telephone number
entered before the FLASH key is stored in the redial
register (EEPROM).
After dialling 1 - 2 - 3 - ’FLASH’ - on-hook Redial is
1 - 2 - 3
After dialling 1 - 2 - 3 - ‘FLASH’ - 4 - 5 - 6 - on-hook
Redial is 4 - 5 - 6.

ISCONNECT FUNCTION
This DIS (disconnect) key is only available if the function
key option is programmed. Touching the DIS key activates
output DP/FL for 800 ms. In this case the telephone set
turns to the ON-HOOK state for this calibrated time, after
which it comes back to the OFF-HOOK mode.
