❖ G3 Line Selection
G4 communication always uses IS-
DN, but G3 communication can
use either PSTN or ISDN. There-
fore, when connected to both
PSTN and ISDN and selecting G3,
you can choose which line to use.
Note
❒ When the optional ISDN Unit is
installed, the line type for "Au-
to" is set to PSTN by default. If
you wish to change the settings,
please contact your service rep-
resentative.
❒ When using G3 with ISDN, you
can use the sub-address and
UUI.
Auto Discriminate
This function is for when G4 is select-
ed. The machine first dials using G4,
but if the destination is PSTN, it
switches automatically to G3.
Limitation
❒ This function requires the optional
ISDN Unit.
Note
❒ When the destination G3 uses TA
(Terminal Adapter) or is attached
to a PBX, and connected to ISDN, it
is detected as G4 and the machine
does not switch to G3.
❒ Depending on the signals of the in-
ternational lines, the Auto Dis-
criminate function cannot detect
the correct line type, thus trans-
missions to overseas destinations
may not be made.
How to Select the Line
When the optional Extra G3 Interface
Unit or optional ISDN Unit is in-
stalled, you can store the Line Select
function in one of the User Function
keys ({
{{
{F1}
}}
} to {
{{
{F10}
}}
}).
When sending a fax, pressing the
User Function key enables you to se-
lect the line.
Preparation
Store the Line Select function in a
User Function key ({
{{
{F1}
}}
} to {
{{
{F10}
}}
}).
See p.154 “User Function Keys” .
