12、75 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 metho

13、ds 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? NBDP setup menu of the NDZ-127J DTE. The following screen appeared by se

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

17、 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.

18、 Max. automatic call series :The limit value of retrying the CALL mode sequence. The interval to retry is 15 minutes respectively. Note ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 3-76 Collective FEC receiving :ON -CFEC receiving is permitted. OFF -CFEC receiving is prohibited. Internal alarm :ON -Internal alar

20、 is lost for 32 times of successive REPEAT condition Finite start/restart :ON -The MODEM returns to stand-by when the times of calling a partner station are reached to 128 in ARQ mode. OFF -The MODEM continues to call a partner station even if the times of calling are reached to 128 in ARQ mode. Tra

21、nsmitter pre-key time :Adjustment of timing from KEY ON to signal output for the transmitter electrical specification. It is also available to arrange the Send/Receive timing between long-ranged partner station. 3-77 3.6.2 ARQ Communication ARQ mode is two way telex communication with a partner as a

22、 destination station. When beginning to call a partner using ARQ mode, it is necessary to select a partner (ID) and a communication channel. The operation from the beginning until the end of the communication with a partner are described in this section. ?Procedure 1. Select Connect ? ARQ and press

23、Enter key. 2. Select a partner station from the following window and press Enter key. If Manual button is selected using Tab and Enter keys, the partner ID and Frequency/Channel can be set manually. Before transmitting, confirm that the selected channel / frequency is not occupied by other station(s

24、). Do not operate JSB-196 during ARQ communication. ATTENTION Note 3-78 3. Select Tx/Rx frequency from the following window and press Enter key. 4. After the following window opened, check the channel condition and if not occupied, press Enter key. If the channel is occupied by the other stations, s

25、elect NO and return to step 3 to select another channel. 5. The channel is tuned automatically and the NCT-196N begins to call a partner station. The following screen is displayed while calling. Note 3-79 6. When the connection is established, the following screen appears and the DTE is ready to com

26、municate with a partner station. Send message to the partner station using the keyboard. In case of sending the previously created message file, press F8 (F.Send) and select the file to be sent on the following window. 7. To terminate communication, press F10 . The following display appears and the
