Below in conjunction with accompanying drawing, introduce the present invention.
Fig. 1 is that hardware of the present invention connects block diagram.
Fig. 2 is a general structure schematic diagram of the present invention.
Fig. 3, Fig. 4 are the program flow diagrams that detects the length of testing speech part in the external testing access software of the present invention.
The present invention provides the passage of subscribers feeder (outside line/interior lines) test and chooses the user for external test instrumentation, the expression state of user, all be that outside access function piece in the application software of AXE-10 switch is realized, the software function module that matches with this outside access function piece has: the user test instrument connection matrix ACCSD of telephone exchange control section APT, subscriber line circuit test bus control SLCT, subscriber line unit control LI, subscriber line unit database SC etc., the operational order of switch CPU and control section APZ receive ADE and exchanger information output AOT.Interface hardware is mainly the connection matrix plate CCB in the connection matrix.Its hardware connects block diagram referring to shown in Figure 1, be about to external test instrumentation and emulation terminal by with switch in connection matrix machine frame 1 in connection matrix plate 11 link to each other, and be connected with subscriber line circuit test board 21 in the user class machine frame 2,22 of subscribers feeders of drawing from subscriber line circuit test board 21 are connected to the user by user's distributing frame 3; The central processing unit of this switch and output importation 3 thereof also are connected with external test instrumentation and emulation terminal and with control appliance 4 that user class machine frame 2 is connected respectively.
The passage that of utilizing that outside access function piece provides of the present invention connects and the control external meters inserts, its major function that can finish has: command reception identification, take the test bus, ACCSD matrix net to the passage of extension instrument port that connect SLCT take, choose subscribers feeder, for extension instrument connecting subscribers participating interior lines and outside line, control length of testing speech, discharge subscribers feeder, transmit bidirectional information to the I/O system.This part function in the switch realizes with software, and the hardware and software that it involved is relevant with the I/O part of the operation of subscribers feeder and switch respectively.By it, the subscriber line test instrument can connect switch and carry out test operation, and really, this instrument also needs the design and simulation terminal partly to be connected with the I/O of switch and to import switch order and receiving feedback information.
The course of work of external testing access software of the present invention is such (referring to Fig. 2): at first import emulation command by the input/output interface of switch, being received emulation command and sent with the emulation command by the operational order receiver module is that the signal A of data analyzes to the external testing access software, external testing access software analysis order is correct just to subscriber line unit database signalling B inquiring user data, simultaneously to subscriber line unit control module signalling C inquiring user state, afterwards, take this matrix to user test instrument connection matrix signalling D request; After connection matrix inverse signal E explanation can take, the external testing access software is to subscriber line circuit test bus control module signalling F request engaged test bus, but after the signal G that receives the engaged test bus, to subscriber line unit database and subscriber line unit control module signalling H with I chooses and the connecting subscribers participating line, make the length of testing speech of the triggering control external testing instrument of counter with the periodicity time sample signal J of system's setting; When the external testing access software receive send by the external testing instrument disconnecting signal after (this signal is a character string, for the manmachine command that is different from switch is called as the subcommand of taking out stitches, its input process is the same with the input emulation command), feed signals K, L, M, N discharge subscribers feeder for subscriber line unit database and subscriber line unit control module, subscriber line circuit test bus control module, user test instrument connection matrix respectively.More than each step all need to send " writing " signal that output information is provided to the switch input/output interface, send " reading " signal to read in emulation command.
The present invention externally tests in the overall construction drawing of access software improved part for control length of testing speech program (prolonging the testing time) with output information program (resolution system restarts) is provided.
Because during the qualitative, quantitative of 13 indexs of subscribers feeder of GB regulation is tested automatically, all relate to and the user between have the action need of interaction situation that the long testing time is arranged, and the test operation time that the AXE--20 switch provides can't be finished as the user at all and made project the phone key testing by prompt tone.External meters is being inserted, test, after the overall process that discharges and the program of each relevant functional block are analyzed and researched, find to keep the time monitoring of testing time relevant with the time monitoring in the outside access function piece, and be limited by CP, overtime (TIMEOUT) time of time of SP order, and mainly contain three in the outside access function piece and monitor overtime timer value T1, T2 and T3, the present invention is designed to 10 minutes with testing time maximum of T 1, test time expand maximum of T 2 is decided to be 15 minutes, subcommand (the i.e. signal that sends by the external testing instrument, this signal is a character string, for the manmachine command that is different from switch is called as the subcommand of taking out stitches) input overtime maximum of T 3 of time be designed to 4 minutes.During program running, whenever receive a time sample signal, the timer in the testing equipment of the using record will add one section and T1 and the T2 value compares, and reaches the program that threshold value is just made timeout treatment.In addition, when test for preventing command timeout, interruption is with the other side's conversation, every less than 5 minutes, a subcommand prompt is just sent out by system, waits for subcommand input (as long as there is information output in system in 5 minutes, order just can overtimely not discharge), finish up to test, promptly receive by the external testing instrument and send disconnecting signal (subcommand of taking out stitches) or time arrival threshold value.According to this thinking, externally also arrange in the prompt of access function piece subcommand input prompt symbol to occur every the time interval of T3, overtime up to T1, T2, manipulate to Meter Test to realize connecting behind the subscribers feeder the longest maintenance 10--15 minute at every turn, make the automatic test probe of external meters insert AXE--10 smoothly and operate, eliminate the situation that failure is interrupted in test.
The program flow diagram of control length of testing speech is referring to Fig. 3, shown in Figure 4 in the external testing access software.This program is after receiving " time sample signal ", enter A section program according to institute tape entry address in the signal, A section program cycle judges whether the log file of testing that has surpasses T1 (testing time maximum) or T2 (test time expand maximum), if surpass maximum, then handle accordingly, if do not surpass, continue circulation and all declared end loop up to all log files of testing.After remaking some tasks, send " time sample signal " and give system, finish then.In circulation, declare T1 overtime before, whether declare test mode earlier idle, if the free time enter J section program, if not idle then to declare T1 overtime.In this circulation, when the log file pointer of testing was initial value 0, program was also changeed the execution of J section, otherwise continued circulation.
J section and K section program are to declare the program of the overtime and respective handling of T3 (subcommand input overtime maximum of time).As long as every the time of T3 character output is arranged, system just can interruptive command, thereby just can not interrupt test yet.J section program begins, and at first whether be type to the first step if declaring testing equipment, is--just directly changes K section program, not--just written document pointer maximum is subtracted 1, change K section program again.K section program cycle is gone in second stepping: from written document pointer I to maximum.Whether one to declare the written document state idle in the circulation? not--outlet finishes with regard to the carryover preface, be--whether two to declare T3 overtime? not--be three to declare the written document pointer 0? being--outlet finishes with regard to the carryover preface, not--written document pointer I is subtracted 1 tax give maximum, getting back to circulates begins and continues to circulate; Two what declare is that T3 puts 0, produces the test pointer, carrying out three then, be to declare the written document pointer 0? be that--outlet finishes with regard to the carryover preface, denys--subtracts 1 with written document pointer I and compose to maximum, get back to the circulation beginning and the continuation circulation.Loop ends was carried out for the 3rd step and is judged: read in interrupt identification and " just carry out ", being--the outlet of carryover preface finishes, not--produce the test pointer, send " time sample signal ", return code is changed to " reopening passage ", and (this signal output prompt, prompting input subcommand are received by system to send " reading interrupt signal " again, keep test can not interrupt), EP (end of program).
Because each switch is connected into a plurality of test probes, and be connected into many I/O terminals and carry out the emulation of order and carry out, so the number of times of access switch is more, number of times and the content of reading and writing the I/O terminal are also very many, make the I/O terminal suspending of programming in the switch limited, cause message in time not spue.And, provide the mutual exclusion of visiting the read/write process in the output information program simultaneously programming error in the outside access function piece, cause the mutual exclusion failure, restarting appears in system.
The mutual exclusion of visit read/write process is made flag bit with multi valued logic in the outside access function piece, so management of process is more more complex than the two-valued function of general utility functions piece.Mistake will occur in case the logic of judging is inconsiderate, and the bidirectional transmit-receive of read/write signal passes in switch CPU and the controlled function piece, as long as wrong, the switch system control program will be reset system environments and occur restarting.The present invention improves it by the determining program of revising read/write process tag in the outside access function piece, promptly write sign and have four kinds of states: " writing ", " rewriting ", " written document rewriting ", " free time ", increase to judge and to have only when being masked as " free time " when writing, just send out " write signal ", " write signal " no longer conflicted, avoid the appearance of restarting.Local Exchange's effect that comes into operation is remarkable after revising software and checking, does not have the identical appearance of restarting, and has reduced the loss of user and telecommunication bureau.
The present invention has tested enforcement, revises software and ordering norms on the AXE--10 switch, and office data generation etc. make the external testing instrument of multiple producer insert AXE--10 and test automatically and achieve success.
