When not using MSN* service:

Program the ISDN subscriber number here. If an another terminal is on the same bus from the DSU, identify the terminals using a sub-ad dr es s.

When using MSN* service:

Program the dedicated ISDN number for the terminal as the 1st ISDN subscriber number. If the customer wishes the machine to answer the calls to a different number, program it as the 2nd subscriber number.

This item is displayed only in the USA models instead of subscriber number - 2 program menu. See the note.

Program the G4 SPID Number given when connected under the US National ISDN.

Program a subaddress to identify the terminal, if two or more terminals answer the call to the subscriber number for G4 fax.

Input a “-” (pause) after the area code.

This item is displayed only in the USA models instead of subscriber number - 2 program menu. See the note.

Program the ISDN G3 SPID Number given when connected under the US National ISDN.

Program a subaddress to identify the terminal, if two or more terminals answer the call to the subscriber number for G3 fax.

* MSN: Multiple Subscriber Number. In this service, more than one number is

allocated to one line (one line can have up to 8 units connected to it).

Important:

Make sure that you input the following items when you connect the machine under the US National ISDN network.

•

Subscriber number: G4 Subscriber Number (G4 Own Number)/ G3 Subscriber

Number (G3 Own Number)

•

SPID Number: G4 SPID/ G3 SPID

NOTE:

SPID (Service Profile Indication Number: G4 and I-G3) menu items are displayed only in the USA models (default). SPID is used when the machine is connected under the US National ISDN network. If SPID is not used, or if the machine is not connected under the US National ISDN network, please turn off with user parameter switch 06 bit 6. This time, subscriber number - 2 program menus (G4 and I-G3) are displayed instead.

1.2.3 REMARKS AT INSTALLATION

Programming the Subscriber Numbers

When programming the subscriber numbers, input a “-” (pause) after the area code. When the machine receives a call, it compares the digits after the last “-” (pause) with the called number attached to the SETUP signal. The machine responds to the call only when the numbers match. For example: If the subscriber number is programmed as, 123-456789, the machine responds to the call only if the last 6 digits of the called number are

456789. If the subscriber number is programmed as, 123-456-789, the machine responds to the call only if the last 3 digits of the called number are

789.

NOTE:

Even if more than one “-” are programmed, the machine compares the digits after the last “-.”
