Title: Network bypassing system
Inventor: JIBIKI MASAYUKI
IPC: H04M3/36
Filed: 1988-05-18
Abstract: PURPOSE:To automatically select a connectable network in case where it is impossible to perform connection for a long time of period by providing a counter to count the number of times of failure of connection at every network to be accessed, limiting access at the time of setting the counter at a constant value, and generating an access code for outgoing to another network automatically. CONSTITUTION:A central processing unit CPU identifies the access code of the network B, and reads out a corresponding non-connected counter from a main memory MEM, and checks a counter value. At this time, the CPU captures a trunk and sends a (network B access code + subscriber number) to the network A via a sender SND when the count value goes less than the constant value. When the non-connected counter shows a value over the constant value, the CPU captures the trunk TRK and sends only the subscriber number out of the (network B access code + subscriber number) received at a register REG from an extension SUB from the trunk TRK to the network A via the sender SND. And the network A connects a line in the network A according to the subscriber number.
