Selecting the Line

G4

Press the {Line Selection} key to light the G4 indicator. ISDN is se- lected.

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.

G4 DisplayPABX

Press the {Line Selection} key to light the PABX indicator.

Note

3

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.

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.

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 select the line.

Preparation

Store the Line Select function in a User Function key ({F1} to {F10}). See p.154 “User Function Keys” .
