3.6 NBDP operations
The NCT-196N DSC/NBDP MODEM has several communication methods in telex (TLX) mode as NBDP function.
Previously created message files or keyboard-typed messages can be sent during the communication. All of
operations are performed using NDZ-127J DTE, and the communication methods and other settings for TLX mode
are described in this chapter. (Regarding the MODE selection for TLX, see “4.3.2 MODE change to TLX”.)
3.6.1 NBDP Settings
Before operations in TLX mode, setup the NBDP functions using SYSTEM Î NBDP setup menu of the
NDZ-127J DTE. The following screen appeared by selecting the menu item.
Each parameter is set as follows:
ARQ/FEC 4- or 5-digit Self-ID : Fixed
GFEC 4- or 5-digit Self-ID : Fixed
ARQ/FEC 9-digit Self-ID : Fixed
GFEC 9-digit Self-ID : Fixed
Answerback : Fixed
Max. FEC error rate : Press Enter key and setup in the input window.
Max. automatic call series : Press Enter key and set a value of 1-99 in the input display.
Collective FEC receiving : Press Enter key to change ON/OFF.
Internal alarm : Press Enter key to change ON/OFF.
Time duration for AUTO : Press Enter key and setup the time in the input window.
Restart : Press Enter key to change ON/OFF.
Finite start/restart : Press Enter key to change ON/OFF.
Transmitter pre-key time : Press Enter key and setup the time in the input window.
After these settings, select the [Save] button or [Cancel] button to finish this setup.
The above parameters showed “Fixed” have already been set and are impossible to be changed.
The meanings of the above items are as follows;
・
Max. FEC error rate :The limit value of error rate to continue to receive CFEC/
SFEC. When the error rate is beyond the value due to the
noisy radio circuit condition or any other signals, the
MODEM stops the receiving and return to stand-by.
・
Max. automatic call series : The limit value of retrying the CALL mode sequence. The
interval to retry is 15 minutes respectively.
