Abstract

PURPOSE:To make a sender recognize that a switchboard takes an alternative route of a trunk line, by varying a kind of a dial tone generated by the switchboard. CONSTITUTION:When a telephone set TELA listens to a dial tone of an originating register trunk ORT2 and a route selecting numeral ODN3 is dialed, a repeating switchboard TSA tries to a select a trunk line l2, but since l2 is busy, alternative routing is taken to l4, the telephone set TELA is connected to the trunk line l4, and a repeating switchboard TSC is started. When the TSC is started, a dial tone is sent out to the TELA from an originating register trunk ORT5. When the TELA listens to the dial tone, it can recognize alternative routing to the route of l4 because said dial tone is not that of the ORT3 but that of the ORT5.

To explain the operation of the trunk exchange network where station A makes a call and connects station BK7Ir, when station A makes a call and dials 0DN2, the LSA connects to station At-6 and activates TSA. When the TSA is activated, a dial tone is sent to station A from a calling register trunk (not shown) within the TSA. Station A hears the dial tone and dials 0DN3, and TSA calls trunk t! Select and set A to t! Connect to and start TSB. When the TSB is activated, it sends out an ear tone to station A as shown in the figure. When Station A hears the dial tone and dials 0DN4,
TSB selects trunk line t3, connects station A to tsK, and connects LS
Start B. When the LSB is activated, a dial tone is sent to station A from a calling register trunk in the LSB (not shown). When Station A hears the dial tone and dials the subscriber number of Station H, the LSB calls Station B and the call arrives at Station H.

In Figure 1, LSA activates TSA through 11, station A listens to the dial tone from TSA, and connects 0DNS.
When TSA attempts to select t2 and encounters t2 busy, TSA will select TSB via TSC.
A detour connection can be made that leads to. If t2 is busy and t4 has an empty trunk line, TSA connects station A and 64 and activates TSC. When the TSC is activated, it sends a dial tone to station A from a calling register trunk within the TSC (not shown). However, since there is no distinction as to whether the dial tone being sent at that time is from TSC or TSB, Station A does not know whether to dial the caller or not. 2 dial) - It was not possible to take a detour using the -n method.
