Abstract

PURPOSE:To prevent occupied switchboard even at the occurrence of a talking fault by dividing a channel of exchange accommodating a switchboard into two groups and connecting the switchboard and the channel via separate operator position trunks. CONSTITUTION:The switchboard 2 is provided with an operator head set 1 and a switch 3, the channels accommodated with the switchboard are divided into channels 9, 10, which are connected to the board 2 via operator position trunks OPTs 7, 8. When an exchange 13 without a switchboard is connected to the switch 3 via the channel 10 and the OPT7, if the channel 10 from the OPT7 is faulty, a central controller 6 of the switchboard discriminates the fault via the channel 10 and a channel controller 11 and an OPT switching order is transmitted to the switchboard 2 via an switchboard input/output controller 4 through a common bus 5. The board 2 drives the device 3 according to the switching order, leads the OPT8 in standby to the board 2 as the active trunk and connects the channel 9 to an exchange 13 as an active channel according to the control of the device 11.

This switchboard provides switching services such as dial calls, and this switchboard is connected to the communication path of the switchboard that accommodates it via an operator body trunk (hereinafter abbreviated as OFT). This trunk supplies telephone current to the switchboard and converts analog signals from the switchboard to digital signals from the switchboard. Since OFTs with such functions have complicated circuit configurations, m''4I is likely to occur.If a failure occurs in an OFT, the switchboard connected via the OFT will be shut down. If a failure occurs in the communication path accommodating the switch, the Kaede number of switchboards will be blocked, causing operational problems.A similar prior art example is Japanese Patent Laid-Open No. 58-25755.

No. 3 communication path 514 (which can be controlled by the communication path control device 17) is connected via digital links 12 and 15 to an exchange containing a switchboard. In this exchange, the communication paths 10 divided into groups are Assuming that there is a created iIwJ state VC, the subscriber 16 mentioned above is connected to the operator via the communication path 10, the OFT 7, the switching device 6, and the headset 1, and the operator executes the subscriber 160 guidance service. However, as mentioned above, OFT uses analog/digital conversion equipment 4!, so the number of fits is large and the failure rate is high.
When the OI'T7 on the J side becomes Jingo or the communication path 10 becomes a failure, the switch central controller 6 determines this failure via the communication path 10 and the communication path control device WIt11, and
Turn off FT and enter 4P operation. That is, switchboard central control device I6

The switchboard 2 drives the switchboard 1113 according to this switching order, pulls the waiting 0PT8 into the switchboard 2 as a working order, and at the same time sets the switchboard 9t to the operating mode under the control of the call path control device 11. Subscribers 16 of 9 service lines 13 that do not have switchboards
and continues the guidance boobis with switchboard 2. Note that if the standby OFT is always powered on and ready for immediate operation, this switching can be done instantaneously. In this way, OF
Even if there is a T failure or a communication path failure WVC, it is possible to provide a highly reliable switchboard system that can provide service without deteriorating the functions of the switchboard. [Effects of the Invention] According to the present invention, the operator Even if a busy trunk failure or communication path failure occurs, switching services can be provided without deteriorating the switchboard functions, and a highly reliable switchboard system can be provided.
