Description of the order of procedure The explanation is related to the successful completion of the procedure.

General case The terrestrial set has dual wireless channels available for sending continuous tones. Set the signal on the channel. The radio channel is specially designed to ensure a reliable signal. Reserved for separate use and used in place of the central tone during short periods of data exchange. A continuous loud sound is heard.

The board set will require the password and dial you have already memorized before you can get free channels. I have a phone number that I used to call. Therefore, when the busy button is pressed, the Everything happens automatically until you set up a connection with a real user.

Linkage procedure A password should be provided in order to activate the board set. after that Free wireless channels are detected by dialing the phone number and When presented, the channel busy button can be pressed, and in this case allows you to view and operate the

As soon as the terrestrial station receives a busy signal, a series of Free tones are removed and any other board set is on the same radio channel. make it impossible to use.

The board set automatically uses its verification code (password introduced by the user) ) and the phone number you dialed.

At Earth, the identification code is The user list is checked against the ship in the group unit's memory.

The terrestrial set automatically increases depending on the dialed brifix. Select the appropriate telephone line. Depending on the Hierarchical Order of the line being used. It also has an adjustment for prefix digits.

After connecting, the board set enables the handset. After the opening signal The conversation will be sent to the board.

This part can also be sent from the board to ground at any time.

After linking, the terrestrial set will automatically revert to continuous channels with free channels. make a sound.

Description of the main signals used Transferring terrestrial sets, free channel sound, Machine matriculation numbers, passwords, phone numbers, and odd-even testing The call sequence (calling procedure) of a message consisting of It is a continuous sound that can be started by the cutter.

A continuous tone sent during the data escape interval between the board and ground. be. Used to signal when a radio channel is in use.

clearing command, This is a command within the earth set that has a reset function.

This signal is sent every time a ground set is not acknowledged, or if the When it is determined that it is correct to cancel an association with a tification code, If the user is not entitled to use due to cancellation or other reasons, please If the phone number is not confirmed or is the wrong number, if the phone line is not available. or the earth user is in use (45 seconds) or the conversation has ended. This is the case.

When receiving this signal, the board set is useless and the sequence is Closed. The code for the special command signal sets the signal for why the association ended. Create it in the

Manual operation required to start a new call It is.

Levitation signal If a busy message received by a terrestrial station is deemed inappropriate, If you refuse, it will automatically ask you to repeat it.

Registration signal If a busy signal comes from a verified board, it will be emitted.

Board set sends.

busy signal The identification code and pre-dialed phone number are Coming later.

This signal is generated by receiving free channel sound sent from earth. Only emitted when a board set is enabled. Accept this signal by grounding This will cause the free channel to immediately stop transmitting sound. Therefore, as long as the channel is in use, no vessel can use this channel any further. Cannot be used for automatic exchange.

clearing signal This is a signal that can be sent from the board set each time and received within the ground set. At this time, a free channel sound is transmitted.

identification code Nominative code This is the ship name code researched by the processor in the ship file and ・It is hardware like a cable inside the set.

password code A secretarial code determined to ensure the accuracy of the user's telephone bill to the subscriber. It is.

This code also classifies the use of some telephone connections (mainline international intercontinental) to the user. It is also used to The nickname is the phone number and the identification code. following the code.
