Description
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.
The data specifies the period of time when the CNG signal is sent out by auto
send.
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.
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.
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.
This timer monitors a response signal at the DTMF process such as DTMF
relay send.
Specifies if the feeding status of current on the ISDN line will be monitored.
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.
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.
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.
No change because X21 is not supported
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.
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.
