Claim 6

The supervising and controlling system as claimed in any of claims 1 to 5, wherein said coincidence signal detecting means provides a coincidence detect signal upon detecting the coincidence signal, and said control means changes, in said coincidence detect signal, said memory selection signal so that the operating condition (Claim 6 continued) and the spare condition of said two memory means are changed to each other.

Claim 7

In a supervising and controlling system for a communication station in a TDMA communication system comprising a supervisory and control apparatus and two TDMA equipments to be used as an operating one and a stand-by one, respectively, in the station, each TDMA equipment having two control memory means to be used as an operating one and a spare one, respectively, each control memory means storing burst signal control data for designating a time position and length of burst signals transmitted from and received at the communication station, the improvement wherein said supervisory and control apparatus comprises: means for transmitting an operating/stand-by selection signal to each of said two TDMA equipments for designating an operating condition or a stand-by condition of each TDMA equipment; storage means for storing significant burst signal control data; means for transmitting a memory selection signal to each of said TDMA equipments. for designating one of two memory means therein as an operating one with the other as a spare one; means for periodically transmitting said signifi- .cant burst signal control data to each of said TDMA equipments; (Claim 7 continued) means for periodically transmitting a verification signal to each of said TDMA equipments for commanding to verify said significant burst signal control data and the content stored in said memory means therein; means for measuring an elapsed time from the transmission of said burst signal control data and producing a time-over signal after lapse of a predetermined time period: and means for detecting a coincidence signal caused by verification at each of said TDMA equipments in response to said time-over signal, said coincidence signal detecting means providing a coincidence detecting signal upon detecting the coincidence signal; means for controlling said memory selection signal transmitting means, said significant burst signal control data transmitting means, said verification signal transmitting signal, said measuring means, and said coincidence signal detecting means; and wherein each of said TDMA equipments comprises: means for switching said two memory means to an operating condition and a spare condition, respectively, in dependence on said memory selection signal; means for reading out the content in one of said two memories therein which is switched to the spare condition in response to said verification signal; and means for comparing said burst signal control data transmitted from said supervisory and control (Claim 7 further continued) apparatus and the read-out data, and, on coincidence of both data, generating the coincidence signal.

Claim 8

The supervisory and controlling system as claimed in Claim 7, wherein said supervisory and control apparatus further comprises means for transmitting a writing signal to each of said TDMA equipment for commanding to write said significant burst control data into said memory means therein, each of said TDMA equipment further comprising means for writing said significant burst signal control data into one of said two memories therein which is switched to the spare condition in response to said writing signal.

Claim 9

The supervising and controlling system as claimed in Claim 8, wherein said coincidence signal detecting means provides a non-coincidence signal at a time when no coincidence signal from at least one of said TDMA equipments is detected, said control means driving said writing signal transmitting means in place of said verification signal transmitting means in response to said non-coincidence signal, and said significant burst signal control data transmitting means so as to transmit said writing signal and said significant burst signal control data to said at least one TDMA equipment.

Claim 10

The supervising and controlling system as claimed in Claim 9, wherein said control means drives said verification signal generating means in place of said writing signal transmitting means, and said (Claim 10 continued) significant burst signal control data transmitting means so as to transmit said verification signal and said significant burst signal control data to said at least one TDMA equipment, after a predetermined time period from driving said writing signal transmitting means.

Claim 11

The supervising and controlling system as claimed in any of claims 7 to 10, which further comprises alarm indicating means, said alarm indicating means being driven at a time when no coincidence signal from at least one of said TDMA equipments is detected at said coincidence signal detecting means.

Claim 12

The supervising and controlling system as claimed in any of claims 9 to 11, wherein, when said coincidence signal detecting means detects no coincidence signal from one of said TDMA equipments which is selected to be the operating condition, said control means drives said operating/stand-by selection signal transmitting means to transmit a stand-by selection signal to said one TDMA equipment and an operating selection signal to the other one of said TDMA equipment.

Claim 13

The supervising and controlling system as claimed in any of claims 7 to 12, wherein said control means changes, in said coincidence detecting signal, said memory selection signal so that the operating condition and the spare condition of said two memory means are changed to each other.
