Abstract

PURPOSE:To enable quick and secure system switching by providing a time division highway, a time division switch and a maintenance controller for both call processor and maintenance processor so that switching of a call processor can be performed directly from a maintenance processor. CONSTITUTION:When a processor (CP)00 has troubles, a maintenance controller (MC)00 transmits trouble information to an MP1 through a control signal channel 7. When receiving the trouble information from the CP00, the MP1 analizes the trouble information, and transmits a system changeover signal to switch a current system from the CP00 to a CP01 through the control signal channel 7 of a highway (HW)5 for connecting the CP00 to the MP1. The MC00 always monitors the control channel 7 of the highway 5, and checks the presence of a general reset demand and a system switching demand after it checks a general instruction and a processor number. In case of a system changeover signal, the MC00 separates the CP00 and switches the CP01 as a current system.

The figure is a system configuration diagram of an embodiment of the system switching method according to the present invention. A maintenance processor (referred to as MP) 1 and each call processing processor (referred to as C and P) 2 are connected to a time division switch (referred to as
A maintenance control device (MC) 3 is located on each call processing processor side, and a maintenance control device (MC) 3 is located on the side of each call processing processor. is duplicated. Further, an example of the configuration of the signal format for Highway 5 is shown in FIG. Highway 5 is a time-division highway for 128 channels, and channels 64 to 67 are assigned to control signal channel 7, channel 0 is assigned to synchronization signal channel 6, and the remaining 123 channels are assigned to communication.9 MC5 is highway 50 control signal. A function that actually performs system switching based on the system switching signal sent from MPl via channel 7 monitoring function and control channel 7, and operation information and fault information of each CP2 to MPI via control channel 7. It has the ability to send. On the other hand, the MP analyzes the operation/fault information sent from each CP2 and sends a system switching signal to the MC3 corresponding to the faulty CP via the control signal channel 7. FIG. 3 shows an example of the format of a maintenance signal sent via the control signal channel. The maintenance signal consists of two parts: a signal command part 8 and a processor (4) number part 9, each of which consists of 1 byte of data. The meanings of the name bits of the signal command section 8 are: SO: maintenance signal display (110 = maintenance signal/゛general signal), Sl knee simultaneous command display (1/.

Further, the processor number section 9 specifies the number of the processor to be switched. There are two types of system switching signals. The first system switching signal is for switching the systems of each CP individually, and is composed of two bytes: a signal command section 8 and a processor number section 9.
The value of each bit of the signal command section 8 is 5O=1, 51=0.
52=O, 53=1. The second system switching signal is for switching all processors from 0 system to 1 system or from 1 system to 0 system at once for program replacement, etc. In this case, only the signal command section 8 is necessary, and the processor number section 9 is not necessary. It is. The values of each bit of the signal command section 8 are 5O=1, 51=1,
52=0°53=1.

If it is 1, it is recognized as a maintenance signal, and then whether there is an 81-bit simultaneous command display. , check. - In the case of an individual command rather than a simultaneous command, check whether the processor number specified in the processor number section 9 matches the own processor number. If they match, check whether there is a general reset request or a system switchover request.
