PURPOSE:To save troubles required for the designation of incoming terminal, by making the designation of an incoming terminal done at an outgoing terminal with a binary value of a prescribed bit-location and converting the binary value into an actual incoming terminal address at an exchanger. CONSTITUTION:In a control signal 1 transmitted from an outgoing terminal, a synchronizing signal 2 is located at first, then a function set section 3, an incoming terminal designation section 4, and finally an end signal section are located. For example, the allocation is as follows: SYN¦SYN¦00000010¦0alpha1alpha2...alpha7¦ 0alpha8alpha9...alpha14¦...¦0alphan-2alphan-1alphan0000¦+¦. The 00000010 is a pattern instructing the simultaneous communication, and alpha1-alphan are bits corresponding to a prescribed incoming terminal, and when this bit is designated, the value becomes 1. The + is an end character representing 10101011. This control signal is transmitted to an exchanger and converted into a respective incoming terminal address with a conversion table. |
