CNG Signal Send Start Time
Time from the end of dialing until the
first CNG signal is sent: 0 to
25500(ms) 1step=100ms
30
This data prescribes the time from the end of dialing until the first CNG signal
is sent in auto origination. Change the numeric value if a telephone
connection is automatically set up for a receiving terminal with a FAX/TEL auto
switching function due to the relationship of timing between termination and
CNG signal send.

CNG Send Time.
0 to 255 sec.
58
The data specifies the period of time when the CNG signal is sent out by auto
send.
CE

85
CNG signal transmission timing by
manual send
0 to 25500ms (1step=100ms)
00
The data specifies the interval between pressing of the Start button and the
transmission of the CNG signal by the manual send. In case failure occurs at
the terminal when the CNG signal is sent immediately after pressing the Start
button, change the value.
CE

90
Disabling the keypad
0:enabled 1:disabled
00
The data is to meet the customer’s needs to perform the send operation only
by using the numbers stored in the speed dial and no dialing using the keypad
will be made.

91
DTMF Idle Monitor Timer.
0 to 255 sec.
45
Sets up time to monitor when no transmission is made at the DTMF process
such as DTMF type relay send. The smaller the value, the more severe the
DTMF signal transmission at the send side. The greater the value, the easier
the operation at the emitting side of the DTMF signal, but there could be wrong
operation occurring resulting in longer monitor time required.

DTMF Response Monitor Timer.
0 to 255 sec.
04
This timer monitors a response signal at the DTMF process such as DTMF
relay send.

Line Power Feed Monitor.
0:Not monitored 1:Monitored
00
Specifies if the feeding status of current on the ISDN line will be monitored.
CE

151*
Line type (G4M0)
1:ISDN-CSDN 2:ISDN-PSDN
3:CSDN 4:PSDN
01
Sets up the line type when various ISDN and digital lines are supported. The
data needs not be changed as only ISDN-CSDN is supported currently.
CE
57
152
Default G4 Line Selection from ISDN-G4
and CSDN-G4 (X21)
0:ISDN-CSDN 1:CSDN(X21)
00
The data specifies priority of selection between the ISDN line and CSDN line
(high speed digital line) by G4 send. The data needs not be changed with G4
model which is not compatible with the CSDN line.
CE
57
153
Default G4-Network Protocol
0:X25PLP 1:T70NL 2:IS8208
02
The data specifies the initial setup of G4 protocol to be used for G4 send. The
data needs not be changed with the domestic machines connected to
INS64/1500(via DPBX). “T70NL” needs to be set up with G4 models
compatible to CSDN lines, only when the CSDN line has the priority.
CE
57
154
Default G4-Network Protocol on calling
ISDN-G4 (X21)
0:X25PLP 1:T70NL 2:IS8280
01
No change because X21 is not supported
57
160
Restrictions on sending ISDN0 (network
guard)
0: Send not restricted 1:Send
restricted
00
The data can be changed when all send operations to the ISDN line via B1ch
need to be restricted. By changing the data, B1ch can be open to be used
only as a receive channel.
CE
57
161
Restrictions on sending ISDN1 (network
guard)
0: Send not restricted 1:Send
restricted
00
The data can be changed when all send operations to the ISDN line via B2ch
need to be restricted. By changing the data, B2ch can be open to be used
only as a receive channel.
