When a dial operation is performed on any telephone STn while the phone is on-hook, "Dial "#"? ”, the first number operated is determined, and if this is “#” indicating the setting of an extension number, “Dial “#”? ” becomes Y, and the telephone STn changes to “Idle?” according to the contents of the variable memory RAM. ”, and if the result is Y, “clear the memory and store “#”” for extension number temporary registration using a part of the variable memory RAM,
In order to notify this, control data is transmitted, the "monitor indicator light" of the telephone STn is set to "60INT blinking" state, and the process moves on to "processing operation data from the next telephone".

In addition, “Onfutsuk?” and “Idol?”
If is N (NO), it is due to call status, busy, redial, etc., and "other processing" corresponding to these is performed.
will be carried out.

Then, in the second cycle, when the 10th digit of the extension number to be set is dialed as one of "1" to "4", "On-hook?" is displayed.
Y, and “Dial “#”? ” through N.
“Dial “1” to “9”? ” becomes Y, and “Memory is “#”? ”, it is determined whether the contents of the extension number temporary registration memory are only “#”, and after this Y, “Dial “1” to “4”? ” becomes Y, “storing the 10th digit in memory” for temporary extension number registration is performed.

In the third cycle, if the first digit of the extension number to be set is dialed as one of "1" to "9", the "On hook?" is Y or "Memory is "#?". ” through N, “Memory is “#” + 10th digit? ``Stores the first digit in memory'' for temporary extension number registration, then checks all the extension number registration areas in the variable memory RAM, and depending on these contents, ``stores the first digit in memory'' for temporary extension number registration. Does it match? ”, and if this is N, perform “self-extension registration” by transferring each digit number to the extension number registration area of the telephone STn as an acceptable one, and accordingly “self-extension number registration”. Perform "Group Settings" and "Monitor Indicator Light/Turn Off".

However, if "Does it match another extension number?" is Y, then "Is the other machine installed?" of the matching number is determined according to the contents of the variable memory RAM, and this becomes N.
Only when this is the case, the process will proceed to "Self extension number registration".

Also, “dial “1” to “9”? ” is N and “Extension number registration in progress?” ” is Y, the prohibited “0” has been dialed, and in order to notify this, the “monitor indicator light 480INT blinks” is made by transmitting control data, and the “dial” 1” to “4”? "N," and "Is the other machine installed?""Monitor indicator light/480INT flashing" is performed in the same way at Y of ".
