4 June, 1999 HARDWARE INSTALLATION

1. INSTALLATION

1.1 HARDWARE INSTALLATION

Install the hardware as described in Chapter 3 of the host fax machine's service manual. Then program the following items.

NOTE:

1) Hardware installation is not required for the I-Schmidt 3 (H548 model).

2) When installing the ISDN G4 unit to the Schmidt 3 (H547 model), make sure to set communication bit switch 16 bit 2 to “1.” Then turn the machine off and on to enable the ISDN unit.

1.2 PROGRAMMING ITEMS

1.2.1 USER LEVEL PROGRAMMING

The following items can be programmed with user function 61 and 64. Make sure that the items are programmed correctly.

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.

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.

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:

This item is displayed only in the USA models.

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).

NOTE:

1) Subscriber numbers are indicated as “SN” on the display in Europe and Asia models, whereas they are indicated as “DN” (directory number) in the USA models.

2) SPID (Service Profile Indication Number: G4 and I-G3) menu items are displayed only in the USA models (default). However, they can be turned off with user parameter switch 06 bit 6. This time, subscriber number - 2 program menus (G4 and I-G3) are displayed instead.

System Switch 0A

- Default communication mode (bit 1)

- Network used for G3 transmission (bit 6) (not required for the I-Schmidt 3)

- Network used for G4-to-G3 fallback (bit 7) (not required for the I-Schmidt 3)

Communication Switch 07

- G4 to G3 fallback On/Off (bit 0)

- Fallback from G4 to G3 reflected in Quick/Speed dials (bit 3)

Change the country code and reset the machine first if necessary. Then change any of the locally required settings and/or the following.

Internal Switch 13

- Condition for fallback from G4 to G3

Internal Switches 17, 18, 1A, 1B and 1C

- G4 to G3 automatic fallback parameters

1.2.3 REMARKS AT INSTALLATION

Programming the Subscriber Numbers

Installation

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 “-.”

PROGRAMMING ITEMS 4 June, 1999

G4 to G3 Fallback

To ensure G4 to G3 fallback occurs for almost all cases, the following switches should be programmed at installation.

G4 internal switch 13 bit 7

: Fallback in response to any CPS code (G4 internal switches 17, 18, 1A, 1B, and

: Condition for fallback from G4 to G3

1C do not have to be programmed.)

Communication switch 07 bit 3

: Fallback from G4 to G3 reflected in programmed

Quick/Speed Dials

: Always start to transmit with G4
