1.1 FAX UNIT

1.1.1 CAUTIONS

NOTE: 1) Never install telephone wiring during a lightning storm.

2) Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.

3) Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.

4) Use caution when installing or modifying telephone lines.

5) Avoid using a telephone (other than a cordless type) during an electrical
storm. There may be a remote risk of electric shock from lightning.

6) If there is a gas leak, do not use the telephone in the vicinity of the leak
to report it.

!

CAUTION

1. Before installing the fax unit, switch off the main power and operation
switches, and disconnect the power cord.

2. The fax unit contains a lithium battery. The danger of explosion exists if
a battery of this type is incorrectly replaced. Replace only with the same
or an equivalent type recommended by the manufacturer. Discard used
batteries in accordance with the manufacturer’s instructions.

2.2 ERROR CODES FOR THE ISDN OPTION

The tables on the following pages show the error codes for the ISDN option.
The meaning of the numbers in the Action column is as follows.

1. Check Layer 1 signaling with a protocol analyzer to determine the cause of the
problem. This may require assistance from a G4 specialist.

2. Repeat the communication. If the problem does not repeat itself, the problem
was a temporary one caused by the user connecting the machine to another
interface. However, if the problem remains, there is a network problem.

3. There is a network problem.

4. There is a network problem. Do the following:

• Check the error bit rate of the network. If it is high, contact the network and

ask them to improve the line.

• Check the network speed (is it 56 or 64 kbps), and make sure that the bit

switch setting is correct. You may also use the dedicated transmission
parameters if this problem only occurs when dialing certain numbers.

• Check that the user dialed the correct number.

Trouble-

5. There is a network problem, or a problem in the machine at the other end.

6. There is a problem in the machine at the other end; ask a technician to check it.

7. The machine at the other end is not a Group 4 fax terminal.

8. The machine is not compatible with the machine at the other end. A

19 January, 2001 FAX SC CODES

2.3 FAX SC CODES

2.3.1 OVERVIEW

When the FCU detects a Fax SC Code condition other than SC1201 and SC1207,
it resets itself automatically (default setting). This initializes the FCU without
erasing files in the SA F memory or resetting the switches.

NOTE: For details on Fax SC Codes 1201 and 1207, refer to the following

sections.

If bit 7 of System Switch 1F is changed to “1”, when the FCU detects a Fax SC
Code condition, it displays the code on the display and stops working until the fax
unit is initialized using one of the following me thods:

• Hold down the “#” and “*” keys for more than 10 s.

• Turn off the main power switch and turn it back on.

2.3.2 SC1201

When the FCU detects an unrecoverable error in the SRAM, which requires a
complete SRAM initialization, the fax unit displays this SC Code and stops.
There is no way to recover from this error condition without a complete SRAM
initialization (all the user and service programmed data will be erased).

Trouble-

shooting

The possible causes are:

• SRAM backup battery defect, or SW1 on the FCU is at th e “OFF” position

• SRAM on the FCU has a physical defect

• Flash memory card or data copy tool connection was loose

2.3.3 SC1207

This is the same as SC1201 except the error location is the SRAM on the Fax
Function Upgrade board.

The possible causes are:

• SRAM backup battery defect, or SW1 on the Fax Function Upgrade board is at
the “OFF” position.

• SRAM on the Fax Function Upgrade board has a physical defect.

• The Fax Function Upgrade board connection was loose.

ISDN TEST FUNCTION 19 January, 2001

2.4.2 BACK-TO-BACK TEST

To make a back-to-back test, you need:

• Two machines, one with the CiG4 board (G4 board used in the FX4, FR4,

ADAM, NAD, Stinger, and Russian) and the other with the SiG4 board (G4
board used with the Schmidt 3, S4, and Kaiser 1).

• Cross rosette
NOTE: You cannot make a back-to-back test using two SiG4 machines.

The procedure is as follows.

1. Switch off the machines

2. Connect two machines back-to-back using a cross rosette as follows.

3. Make the following bit switch adjustments:

• In the machine acting in NT mode (CiG4 board), set bits 0 and 1 of G4

parameter switch 0D to 1.

• In the machine acting in TE mode (SiG4 board) set bit 0 of G4 parameter

switch 0D to 0 and bit 1 to 1.

4. Reset the machines by switching them off, waiting a few seconds, then
switching back on.

5. Place a document in one of the machines, dial a number, then press Start.

6. After you have finished the test, set bits 0 and 1 of G4 parameter switch 0D
back to 0, then reset the machine.

NOTE: The following cannot be tested using this procedure:

• ISDN G3 communication

• Point to Multi (Like a broadcasting test, f rom one point to many places.)

03 04

The four-digit hexadeci mal value (N) after “L” indicates the rx level.
The high byte is given first, follow ed by the low

byte. Divide the decimal value of N by -

16 to get the rx level.
In the above example, the decimal value of N (= 0100 [H]) is 256.

So, the actual rx level is 256/ -16 = -16 dB

In some countries, a time delay to answer a
call is requir ed.
Otherwise, use this switch as follows:
If the machine is connected to the same bus
from the DSU as a mode l K200 is connected,
the machine receives mo st of the calls
because the response time to a ca ll is faster
than the K200.
If the customer wants the K200 to receive
most of the calls, adjust the response time
using these bits.
If the customer does not want one machine to
receive most of the calls, use subaddresses to
identify each terminal.

Action when receivin g [SETUP]

Normally, the 3rd octet of cal led p art y
subaddress information in the [SETUP] signal
is set to NSAP. However, some networks may
add “user-specific” subaddress to the
[SETUP] signal, and the result of this is that
the machine won't answer t he call if a

So, change this bit to 1 to let the machine

G4 to G3 fallback

Bit 0 of Communication Switch 07 must be at 0, or fallback from G4 to G3 will be

The CPS codes for which fallback occurs are decided as follows.

• G4 bit switch 17, bit 7 - If set to “0”, fallback occurs on receipt of a code from a
set that depends on the country code. If set to ”1”, fallback occurs for the 5 CPS
codes programmed in bits 0 to 6 of G4 bit switches 17, 18, 1A, 1B, and 1C, in
addition to the country code set.
Note that if G4 bit switch 18, bit 7 is set to “1”, the CPS code set that is used is
always the Universal set, regardless of the country code setting.
