Bit Switch ISW04 Comments:
Bit 0: 0: T = 10 s. Sufficient time to ensure continuous link operations for most
circumstances.
1: T = 30 s. This setting is used for satellite communication paths, high traffic
congested networks, and when CCITT compliance is required for overseas
acceptance tests.
Bit 1: 0: Immediate. The DCE can respond to the modulo 8 SABM command frame
with DM, and will not disconnect the call. In turn, the modulo 8 machine shifts up
and sends the modulo 128 SABME link set up command frame.
1: Indirect. When SABM is received from the modulo 8 machine, the DCE
disconnects and does not send the DM frame. When the call is reconnected, the
modulo 8 machine shifts up and sends SABME to establish the data link.
Bit 2: 0: Immediate. The DCE can respond to the modulo 128 SABME command
frame with DM; the call is not disconnected. The modulo 128 machine will
fallback by sending SABM, the link setup command for modulo 8 machines.
1: Indirect. When SABME is received from a modulo 128 machine, the DCE will
disconnect the call. SABM is sent when the call is reconnected.
Bit 7: When doing a PSDN back-to-back test, one of the fax machines must appear to
be a DCE. This is done by setting this bit to 1 in one of the machines before
doing the test.

Bit Switch ISW05 Comments:
Bit 0: This is used for packet networks and packet-type ISDNs. Between
communications, Call Request (CR) is used normally, but Reset Request (SQ)
can be used instead if this bit is at 1. If the network sends SQ, and if any packets
are stuck in the network (such as due to communication faults) between the two
terminals, they are cleared before communication. The setting of this bit depends
on the network; in general, if the network is not complete, set this bit to 1.
NOTE: Try setting this bit to 1 if layer 3 cannot be established.
Bit 2: The protocol ID is contained in the CR packet. This bit is set to 0 if the machine
is connected to TYMNET.
Bit 5: Collect calls known in the CCITT recommendations as "received charge". This is
only used for PSDNs and packet-type ISDNs. The CR packet informs whether or
not the call is a collect call.
0: Refuse collect call
1: Accept collect call
Bit 6: Ricoh 57-second timer. This is only for PSDN networks. Normally, if Call
Connected (CC) is not received in reply to CR within 180 seconds, the
communication is terminated. This time can be reduced to 57 seconds by setting
this bit to 1.
0: Disabled (normal time = 180 seconds)
1: Enabled
Bit 7: This bit can be set to 0 if the machine is connected to an ISDN through a
Terminal Adapter, or if it is connected to a CSDN that uses ISO8208 (T.90).
0: Fixed – Packet size (P) = 2048 Window size (W) = 7

Bit Switch ISW06 Comments:
Bit 0: Inclusion of the sending DTE address in the Call Request packet (S:CR) – This
bit is only for packet networks. The CR packet should contain the receiving side's
DTE address; the transmitting side's may be included as an option.)
Bit 1: Inclusion of the transmitted/received DTE address in the S:CR packet – This bit
is only valid if the machine is connected to an ISDN through a Terminal Adapter,
or a T.90 CSDN; the CR packet is sent to match the IS8208 (T.90) layer 3
protocol. If the bit is 1, the other end's identifier can be seen in the display panel
a few seconds earlier than normal.
Bit 2: Inclusion of DNIC (DN)/CC (ISDN) in the S:CR packet – If the machine is
connected to the Federal Express network, this bit should be 1.

Bit 0: 0: Contracted – If the logical channel number (LCN) is set to a different number
(see PSW0A) from the actual value, communication is still possible.
1: Not contracted – Communication is not possible under the above conditions. It
may be necessary to set this bit to 1 to carry out certain PTT approval tests.
Bit 1: The setting of this bit depends on the network specifications.
Bit 2: 0: Packet and packet window sizes are as programmed:
(see packet, PSW07-0, 1, 2, 3 and packet window, PSW08-0, 1, 2, 3)
1: The packet window size (W) is fixed according to the packet size (P) as
follows: if P = 128, W = 5; if P = 256, W = 4; if P = 512, W = 2;
if P = 1024, W = 2. These match the Japanese DDX-P network specifications.

b) For X.21, there is no CPS (Call Progress Signal) start code.
1: DDX:
a) At the end of dialing on the V.24-200 interface, + is used.
b) For X.21, CPS start code, SI, is checked.
0
Bit 1: 0: Normal X.21 dialing is used
1: A prefix of "5/16-" is added at the start of the number. This is used on the
DATEX-L network in Germany.
Bit 2: If the user wishes to connect the machine to the PSTN with a V.25 interface
(V.24-200 parallel autodial), setting this bit to 1 will cause the machine to
automatically insert the "SEP" code at the start of the telephone number.
Bit 3: For machines with a V.24-200 autodial, the rough timer provides a timing
adjustment to overcome problems that some DCEs exhibit when working through
this interface.

Bit Switch ISW0F Comments:
Bit 2: Enable this bit to check the Layer 1 timing signals (TX: ST2 and RX: RT) during
Layer 2 back-to-back testing in order to study compatibility with the network
DSU.
If the back-to-back test is successful when this bit is enabled, but the network
communication is not, the data transfer timing signals may not be compatible
with those of the DSU. (REF: PK Type 1 test, FAX7000D Service Manual, pages
3-6 and 6-22)
Reset this bit to 0 after testing. See section 4 and PSW0D, for test procedures.
Bits 3 and 4: Method of entering receive mode in V series communication. The setting
of these bits depends on the type of DSU or DCE.
Bits 5 and 6: Terminal board test – This can test the operation of each signal on the
V.24(V.28), V.35, or X.21* jack. The procedures follow.

Test Procedure for bits 5 and 6
NOTE: When all testing is done, restore the dip switches to OFF,
the bit switches for normal operation, and reset the machines:
See System Reset Note, page 8.
Output "H" data on IO output port (all output pins high – ISW0F = 01000000):
Disconnect the machine from the DCE. Set the CVG4 dip switches below the dial
connector to on. Then, set bits 5 and 6 of switch ISW0F to 0 and 1 respectively. Reset
the machine: hold down the Stop key for about 12 seconds. The output pins of the
machine will all read high on a multimeter.
Output "L" data on IO output port (All output pins low – ISW0F = 00100000):
The test procedure for output low is the same as for output high. In this case, set ISW0F5 and 6 to 1 and 0 respectively.
Input Port Data on LCD (Machine Input Test Mode) – Test 1:
Connect two machines with the V.35/V.24(V.28) back-to-back cable. CVG4 dip switches
can be on or off.
On the machine to be tested, set ISW0F-5 and 6 to 1 (01100000). On the other machine,
set bits 5 and 6 for either "output high" (01000000) or "output low" (00100000). Then
reset both machines: hold down the Stop key for about 12 seconds.
The output pins on the other machine will go high if "ouput high" was selected (or low, if
"output low" was selected), causing the input pins on the tested machine to go high (or
low). On the tested machine, the following pins should go high (or low):
V.35: D(CS), E(DR), F(CD), J(CI), R(RDA), T(RDB)
V.24 (V.28): 3(RD), 5(CS), 6(DR), 8(CD), 22(CI)
V.24-200 (Auto Dial): 3(ACL), 5(PND), 13(DSC), 22(DLO)

LCD Display
The display in the bottom right of the LCD shows the status of the input pins as a
four-figure (two-byte) hexadecimal code. (This code is displayed one byte at a time; the
high byte is displayed for 2 seconds, and the low byte is displayed for 1 second, and this
is repeated indefinitely). the make-up of this code depends on the status of the input pins
as shown in the following table:

Bits 0, 1, and 2: 000: Normal Operation. Always reset the bits to 0000 after testing.
001: CSDN Layer 1 (Physical Link). This test checks data
transmission (ST2) and reception (RT) signal element timing for
the V.24 and V.35 physical connections. Signalling proceeds from
layer 1 when Start is pressed. The clock must be enabled in one
of the machines by setting dip switches as indicated in the section 4.
010: CSDN Layer 2 Back-to-Back Test (Data Link). This test doesn't
check layer 1 signal element timing. The clock must be enabled in one of
the machines by setting its dip switches. See section 4. Layer 1 is
established, and signalling begins from layer 2 when Start is pressed. This
setup is also used for high speed operation without a network, using DSUs
on a leased or dedicated line (no manual dialing).
010: CSDN Layer 2 Network Test (Data Link). Each machine is
connected to a network through a DSU. Connection between the DSUs
must be established before beginning the test-dialing is manual only.
Layer 1 is not checked. Clock signal is provided by the network: all the dip
switches are set to OFF.
100: PSDN Packet Back-to-Back Test. One machine must be set as DCE
(ISW04-7). Signal element timing (layer 1) is not checked. Clock is
enabled by setting the dip switches in one of the machines. See section 4.
Layer 2 is established when the machine is turned on, and SQ/SF (Reset
Request/Reset Confirm) packets are exchanged. Communication begins
from the CR (Call Request) packet, when Start is pressed.
100: PSDN Packet Network Test. Each machine is connected to a
network through a DSU. Connection between the DSUs must be
established before beginning the test. DCE does not need to be set, and
clock is provided by the network. SQ/SF packets are exchanged and
communication begins with the CR packet when Start is pressed.

4 BACK-TO-BACK TEST
NOTE: When testing is done, turn the dip switches to OFF, restore bit
switches to normal operation, and reset the machines: hold down
the STOP button for about 12 seconds. See System Reset Notes, page
8.
These tests are useful for demonstrations, training coursed, and machine testing
and troubleshooting. A cable rated for both V.35 and V .24 is used to connect
the machines directly to each other, back-to-back. The layer 2 test can be used
for compatibility problems: If the layer 2 test was successful but communication
was not, the machine's data transfer timing signals may be incompatible with
those of the DSU.
CSDN Layer 1 (Physical Link) Test - Direct
Two machines using CSDN protocol are directly connected to each other with
the V.35/V.24 back-to-back cable. The bit switches for the CSDN layer 1 test
mode and the cable rate are selected. The dip switches of ONE of the machines
are set to enable the clock. After the document has been placed in the ADF, the
call is initiated at the machine. Signalling begins when Start is pressed. The
layer 1 data transfer signal element timing pins, ST and RT, for V.24 and V.35
connections are tested.
CSDN Layer 2 (Data Link) Test - Direct
Two machines using CSDN protocol are directly connected to each other with
the V.56/V.24 back-to-back cable. The bit switches for the CSDN layer 2 test
mode and the cable rate are selected. The dip switches of ONE of the machines
are set to enable the clock. With the document in position in the ADF, the call is
initiated at the machine. Signalling stars from layer 2 when the Star button is
pressed. incompatibilllty is ignored, and layer 1 is established. Data transfer
signal element timing is NOT tested.
PSDN Packet test Direct
This test is a version the CSDN direct test above. Two machines using PSDN
protocol are directly connected to each other with the V.35/V.24 back-to-back
cable. The PSDN test mode and the cable rate are selected by bit switch. The
dip switches are set to enable the clock. In addition, for the back-to-back PSDN
test only, one of the machines is set as DCE. the physical link and the data link
are established at power up. Network layer Reset Request (SQ) and Reset
Confirmation (SF) packets are exchanged, and communicating begins with the
Call Request (CR) packet when the Start button is pressed.

6 TROUBLESHOOTING
6.1 CVG4 STATUS CODES
When the real time display bit switch, PSW0E-0, is turned on, CVG4 status
codes will be displayed as hex codes in the operation panel character display
during communication. The default position of the switch is off (0).
When PSW0E-0 is on, the status codes of all G4 network levels, 1 through 7,
are also displayed as hex code in binary form in a row of LEDs on the CVG4
board. The LED number 1 represents bit 0.
When the PSW0E-0 is off, the status codes will not appear in the character
display, and only layer 1 and 2 codes will appear in the LEDs.
