response is received. T3 = TL1 + TL2. TL1 is the time
between receiving the flag response from the other end and
sending the first SABM. TL2 is the time between each
SABM sending attempt
Bit 1: 0: Immediate – When link layer modulo 8 mode is
established, negotiation between terminals is available
concerning the link layer modulo. Shift up to modulo 128
mode is done using R:SABME.
1: Indirect – When link layer modulo 8 is established, S:DM
is sent after R:SABME
Bit 2: 0: Immediate – When link layer modulo 128 is established,
S:SABME is sent. Then if R:DM is received, fallback is done
by sending S:SABM.
1: Indirect – If R:DM is received, the call is disconnected and
then 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.
6 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 packettype 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 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 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.

Test Procedure for bits 5 and 6
Output "H" data on IO output port (all output pins high – ISW0F =
01000000):
Disconnect the machine from the DCE. Set the CVG4 dip switches beneath
the dial connector on the back panel 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 10 seconds. The output pins of the machine will all read high on a
multimeter. After the multimeter test, reset the dip switches: hold down
Stop for about 10 seconds.
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 bits 5 and 6 of ISW0F to 1 and 0 respectively.
Input Port Data on LCD (Machine Input Test Mode) – Test 1:
Connect two machines with the back-to-back cable, 28433-001. Dip
switches can be On OR OFF. On the machine to be tested, set bits 5 and 6
of switch ISW0F 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 10 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)
X.21: 4(RA), 5 (IA), 11(RB), 12(IB)
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 makeup of this code depends on the status of the input pins as shown in the
following table:
Bit Meaning Bit Meaning

Correct codes are as follows:
Output high: V.35 – 7F0F, V.24(V.28) – 7F0F, V.24-200 – 7F8F, X.21 –
7FFF
Output low: V.35 – FFFF, V.24(V.28) – FFFF, V.24-200 – FFFF, X.21 –
FEFF
After testing, reset the bit switches, and hold down Stop for about 10
seconds to reset the machine.
Input Port Data on LCD (Machine Input Test Mode) – Test 2:
Disconnect the machine from the DCE. Then set bits 5 and 6 of ISW0F to 1
(01100000). Hold down the Stop key for about 10 seconds. If the test is
correct, the display in the bottom right corner of the LCD should be as
follows:
X.35 or X.21: 7FFF V.24(V.28): FFFF
When all testing is done, restore the dip switches to OFF, reset the bit
switches for normal operation, and reset the machines: hold down Stop for
about 10 seconds.

Bits: 0, 1, 2, and 3: The Logical Channel Group Number (LCGN)
provides packet routing information over a switched
data path within the packet network. It indicates the
Packet Assembler/Disassembler (PAD) connection.
It is used for PSDNs and ISDNs when there is more
than one channel to the network. The value is
determined by contract between user and network. If
there is no contract, the factory setting can be used.

3 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
SystemReset Notes, page 3-3.
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.

PSDN Packet Test-Network
This test is a version of the CSDN network test above. The
machines are set for PSDN test mode. Two machines using PSDN
protocol are connected to the network through DSUs. The clock is
provided by the network, and the connection to the DSU is normal
DTE to DCE connection. The dip switches are OFF. Power up
establishes the data link layer. Network packets SQ and SF are
exchanged, and communication begins with the CR packet when
Start is pressed.
CSDN Layer 2 -Network
CSDN Layer 2 Test is similar to the direct test. The same CSDN
layer 2 test mode setting is used. Signaling starts from layer 2
when Start is pressed. However; 1. The CSDN machines are
connected through DSUs to a network. 2. Timing is provided by
the network, and the dip switches are OFF. 3. The call is initiated
manually at the DSU.

5. Troubleshooting
5.1. CVG4 Status Codes
When the real time display bitswitch, 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 that switch is off (0).
When PSW0E-0 is on, the status codes of all levels, 1 through 7, are also
displayed as hex code in binary form in a row of LEDs on the CVG4 board.
The LED representing bit 0 is closest to the G4 connector.
When the PSW0E-0 is off, the status codes will not appear in the
operation panel character display, and only layer 1 and 2 codes will
appear in the LEDs.
