Description

The invention relates to a storage system for data processing systems in telecommunications, in particular program controlled telephone exchanges, following program instruction words and contains data, with a control arrangement for extracting and entering selected instruction words and data from or to the memory system for executing and generating the program instruction words of command signals based on program command words and with a on the ■ input-output system responding to mandosignals.

The problems identified here occur with many types of data processing systems. In order to explain however, these problems and their solutions should be based on a program-controlled telephone exchange be described as an example of a data processing system.

A large number of central office offices within the United States from America can be seen as belonging to a certain class of office as a fixed area of operating features meets the requirements for these offices and there the maximum size and Traffic capacity of each of these offices' a certain Does not exceed the limit. Even so, each office has many different characteristics that the office assigns stamp a one-time execution. For example, within a given class of offices there are:

A. Many system features,

B. many classes of participants,.

C. many types of interconnection lines,

D. A wide range of traffic requirements. '

There is no doubt that in no case are two offices identical from the outset with regard to all of these points.

Furthermore, during the life of an office there are requirements regarding changes to the Traffic capacity, office features, number of subscriber and trunk lines, etc., and these changes are also of a special kind for the individual offices.

The program and data for a program controlled telephone exchange have one large scope, and the organization of this information within the storage facility of such offices must be able to adapt to the special characteristics of the individual offices Class and the different growth of such offices offer.

In known data processing systems, the organization of programs and data is absolute Little attention has been paid to storage locations. The programs are generally like this constructed and compiled so that commands and data are randomly mixed in the memory map. When a new program is created for each new telephone equipment and every time Changes are to be made in a particular office, there is a high probability for the occurrence of errors in the compilation of the program and in the assignment of absolute Addresses within the memory. There are also considerable costs involved in the entire program and the data of the office must be recompiled to reflect changes in the operation or to carry out the official size. Even more significant is the fact that it is seemingly impossible to bring the newly compiled programs and data into the system without interrupting operations.

Often times, new and unusual operating features are developed, and older telephone exchanges must be updated to provide such features. When

ίο System programs and data compiled office by office the addition of a single feature is very costly for these offices and complicated, because this is accompanied by the new compilation of programs and data for each individual

Office is required. '

The invention is based on the object of keeping the program and data information in the memory system for data processing systems in telecommunications, in particular program-controlled, remote speech exchange systems organize so that a better and more reliable reinstallation and an orderly one Growing such plants is possible.

To achieve the object, the invention is based on a storage system of the type mentioned at the beginning Kind and is characterized in that the storage system is three distinct, discrete and mutual has exclusive sections, namely a first section containing fixed sequences of program instruction words and fixed data, a second section containing variable data; and a third section containing a plurality of associated Storage locations for information relating to connections being established.

b) define the equipment assemblies forming the input-output system

... "■ ·

and in that the control arrangement comprises means based on the first and second sections derived information, address to gain information from the third section and

+5 to control the input-output system.

The one stored in the first section of the storage system Program part can then be a standard program that in all telephone exchanges one Type is used. This standard program is essentially the same length and the same Information content 'for all offices and can always be in the same absolute addresses of the storage system be saved. It therefore only has to be formulated once for all offices, compiled and

to be checked. In the refurbishment of offices ^lf no difficulties arise with regard to the operability of the standard program. In addition, changes that arise when an office is enlarged, other traffic conditions or operating features and which do not affect the standard program can be carried out more easily because the standard program remains unchanged. In this way, significant savings can be made when installing new installations and making changes.

The respective peculiarities of the offices can then be found in the second and third sections of the storage system be formulated and stored.

A storage system in a telephone system that has three discrete sections, each of which defined by at least one specific range of non-overlapping, absolute memory addresses is known per se. A division of the control program into three different sections is not provided.

A better understanding of the invention can be obtained from the following description in conjunction with FIG the drawings. It shows

According to FIG. 2, the memory system contains a semi-permanent memory (program memory 202) in which the general program (with the exception of some maintenance programs) and certain data that are only changed occasionally are stored, and a temporary memory (conversation memory 203) in which a few maintenance programs and data that are subject to rapid change are stored. The following. Explanation is in connection with such. Executed memory arrangement, but the basic ideas of the invention can be used in the same way in telephony switching systems that have only one type of memory and not necessarily both, have the same organization and the same data processor (central controller 201) or even perform the same services and functions.

A complete understanding of how to program control of a central office operator The basic idea applied can be obtained from the German patent 1072273. .

The main task of a telephone switching office _r is to use a variety of communication paths ,, ie subscriber and connecting lines, according to the requirements of the news channels. The main service of communication routes is to establish connections in response to information obtained from a calling communication route. However, as is well known, modern central office offices have a variety of modes of operation and are designed for a number of classes of communication routes. For example, there are private subscriber lines, lines for two-way lines, lines for private branch exchanges, etc. Similarly, there are a large number of types of trunk circuits such as incoming trunk circuits, outgoing trunk circuits and attendant trunk circuits. Furthermore, numerous types of signaling systems are used in conjunction with both the subscriber and trunk lines. In addition, modern telephone exchanges offer the subscribers many unusual operating features, for example multi-frequency signaling, temporary call transfers, etc. Even if two offices serve approximately the same number of subscriber lines, the traffic requirements for the two

i; the offices differ greatly from one another. For example, an office in a business center may have

ίο are extremely high traffic density, while the other office serves a remote part of the city, in which only relatively few conversations occur. ... Each of the Ρμη ^ ε explained above, whether it concerns the type of operation for a subscriber line, the type of signaling used for a subscriber or connection line, the type of connection line circuit or the traffic capacity of the office, contributes to the specialty of the Office at. Although originally only one office may be required, the restricted classes of '. Subscriber lines and connection lines are served and allow very limited operating features, so provision must be made that they can be made available in the event of later growth. Very simply one could say that the office program contains a large number of program groups, that a special group is required for each of the various service features, and that separate groups are required to service each of the various classes of subscriber lines, trunk lines and properties which these Subscriber and connecting lines can be assigned. .

Organization of the switching system.

1 shows a general block diagram of a program-controlled data processing system. The control arrangement 201 is designed so that it can read information (both commands and data) from the memory system 171 and write information (data) into the memory system 171. The control arrangement carries out sequences of program command words obtained from the memory system 171

tern and generates output signals for controlling the input-output system 170. In this embodiment, the memory system 171 has a semi-permanent program memory 202, in which both sequences of program command words and data are stored, and an erasable conversation memory 203 , in which data is stored are.

The central control arrangement 201, hereinafter referred to as "central control" for short, processes information that has been obtained from the input system 172 via the cable 208 during the execution of the sequences of program command words obtained from the storage system 171 , and generates signals on the basis of this information Control of both the input system 172 and the output system 173. As the following explanation will show, the one in FIG. Telephone switching system 2 shown as an example as regards the general organization of the data processing system of FIG. 1.

F i g. Fig. 2 shows a schematic block diagram of a telephone exchange. In this System is a large number of subscriber sets,

e.g. 260 and 261, which are connected to the switching network 220 via subscriber lines 262 and 263. On the right side of the FIG. 2 two types of trunk frames are shown. The universal trunk frame 234 is designed to accommodate a large number of trunk and service circuits that require a certain fixed number of sample points and control points, while the mixed trunk frame 238 is designed to accommodate those Trunking and control circuits are suitable for which, because of their complicated structure, a greater number of sampling and control points is required than can be permitted in the circuits of the universal trunking frame 234. Each of the trunk frames 234 and 238 includes trunk and service circuits, a trunk sampler such as 235 and 239, trunk signal distributors such as 236 and 240, and cable receiver circuits 237 and 241 . The switching network 220 , under the control of commands from the central data processor 200, selectively establishes connections between subscriber lines, such as 260 and 261, between trunk circuits and between subscriber lines and trunk circuits.

The central data processor 200 comprises the program memory 202, which contains sequences of program command words and the relatively fixed data of the system, the conversation memory 203, which is an electrically variable memory and contains the relatively rapidly changing data of the system, and the central control 201, the information from the program memory 202 and the conversation memory 203 in order to write information into the conversation memory 203 , to execute the sequences of program instruction words obtained from the program memory 202 and to generate commands which the switching network 220, the elements of the connection line frames 234 and 238, the central impulse distributor 243 , main scanner 244, teletype unit 245, program memory card writer 246, and automatic billing unit 247 . The central pulse distributor 243 is in principle a converter which receives addresses and command information via the cable 207 from the central controller 201 and then generates output pulses on the individual wires of the cable 211. The central pulse distributor is a high speed device used to energize elements of the plant such as network controllers 222 and 231 and to control portions of the trunking circuits of frames 234 and 238 .

The main scanner 244 responds to commands from the central control via the bus 213 and, based on such commands, is able to query certain test points in the entire system and the high-speed scanning points, which operating circuits are assigned that are used to display and store call signal information e.g. dialing pulses, multi-frequency tones, etc.

The teletype unit 245 and the program memory card writer 246 are for administrative purposes and are not necessary for an understanding of the invention. Similarly, the automatic billing unit 247 is used to record details required to bill subscribers.

Central data processor

The central data processor 200 comprises according to FIG. 2 the central control 201, the program memory 202 and the conversation memory 203. The in FIG. 3 below the dash-dotted line and in F i g. Central control 201 shown in FIGS. 4 and 5 carries out data processing functions corresponding to sequences of program command words. The program instruction words belong to two broad groups, namely decision instructions and non-decision instructions. .

Decision commands are generally used in order to carry out desired actions on the basis of existing conditions with regard to subscriber lines or trunk lines served by the switching system or on the basis of conditions with regard to the maintenance of the system. Decision commands indicate that a decision is to be made with reference to certain observed conditions, and the result of the decision causes the central controller 201 to switch to the next command in the present sequence of command words or to jump to a command in another sequence of command words. Decision commands are also called "conditional jump commands".

Non-decision commands are used to communicate with units outside the central controller 201 and both to move data from one location to another and to process the data logically in accordance with certain defined commands. For example, data can be linked to other data using the logical functions and, or, exclusive-or, etc. In addition, data can be complemented, and data can also be moved and rotated.
Non-decision commands therefore carry out certain data processing and / or transfer functions, and after these functions have ended, most non-decision commands cause the central controller 201 to execute the next command in the sequence. A few non-decision instructions become unconditional jump instructions _? called. These indicate that there is a jump from the current sequence of program instructions

another sequence of command words independently

of a decision to take place.

The sequences of instruction words stored mainly in the program memory comprise ordered lists of both decision and non-decision instructions which are to be executed one after the other. The processing of data within the central control takes place on a purely logical basis. Subordinate to the logical operations, however, the central controller 201 performs certain arithmetic functions to a lesser extent. The arithmetic functions generally do not relate to the processing of data, but are primarily used when obtaining new data from the memories, for example from the program memory 202, the

Call memory 203 or specific flip-flop registers within the central controller 201.

The central control 201 processes data on the basis of the command word sequence and generates and transmits signals for the control of other units in the system. The control signals, which are called commands, are optionally to the program memory 202, the conversation memory 203 and the input; Output system 170 transferred. "

The central controller 201 is, as its name indicates, a central unit for controlling all other units in the system. The central controller 201 mainly comprises:

A. A variety of multi-level flip-flop registers, such as XR, YR, ZR, JR, and K,

B. a variety of decoding circuits, such as OWD, BOWD and MXD,

C. a variety of dedicated trunking systems for communication between different ones Elements of the central control,

D. a large number of receiving circuits for receiving input information from a large number of sources, for example 301, 302,

308,;

E. A variety of transmission circuits for the transmission of commands and others Control signals, for example 300,303,502,503 and the command converter,

F. a large number of sequential circuits, for example SEQ 1 to SEQN,

G. Clock sources, for example CLK,

H. a large number of gates (command combination gates) for combining timer pulses with direct current signals derived in the system.

The central controller 201 is a synchronous system in the sense that the functions within the central controller are under the control of a polyphase microsecond clock source ^ LK, which supplies timing signals for performing all logical functions within the system. The timing signals derived from the clock source CLK are combined with DC signals from a number of sources in the command combination gate circuit. The details of this circuit are not shown in the drawings, because then the overview with regard to the basic concept of the system according to the invention would suffer.

Organization of information in the storage system

F i g. 6 shows the organization of information in program memory 202 in seven memory locations, starting with φ through φ. In the drawing, the arrangement of the information and the size of the blocks, which represent the seven locations, do not correspond to the actual conditions, but merely serves to illustrate the basic idea of the invention. The same applies to the three blocks labeled (X), (S) and (£) in FIG. 7, which show the arrangement of the information in the conversation memory 203 .

General program - general data

In Fig. 6, the place φ contains the general program and the general data for all offices of a specific Class are in common. The information

35 in this area are always located in the same absolute addresses of the program memory, and the content is fixed for all offices of the same class. These associations are made by the manufacturer and, in general, the information is entered into memory by the manufacturer. With only a few exceptions, the general program includes all the program sequences that are required both for carrying out the call processing and the maintenance functions for the class of offices for which a program is being prepared. The exceptions concern the individual, mutually exclusive programs that are in location (2) of the program memory and are to be described later, "as well as a few maintenance programs that are in the conversation memory and are not further described.

The general data contain information for the creation of tables, which are often used in the course of call processing. The general program is able to prepare the tables on the basis of this data and to save them in place (a) in the call memory. An example of the type of tables that are created and stored in call log is a "diagonal table". The data word used in the exemplary embodiment contains 23 information bits. The diagonal table comprises 23 words which are arranged one after the other in the location © of the conversation memory 203. In the first word, the rightmost bit position is a binary "1", and all other bit positions are binary "0" values. In word 2, the second bit position is a binary "1", and the first and all other bit positions are binary "0" values. In the other words in the table, the bit position corresponding to the word number is a binary "1", and all other bit positions are binary "0" values. This gives the name diagonal table.

"The general program and the general data are prepared by the manufacturer, and this information in the program memory 202 is generally only changed when the office is transferred to a new general class due to the expansion of the office. However, such a change is very unlikely, since a single general program encompasses both a wide range of traffic demands and a wide range of service features.

. ■ ■ Mutually exclusive, extensive
- programs

^: Certain program sequences are very extensive and are used in an office on a mutually exclusive basis. For example, when setting up an office, a specific concentration ratio is specified for the subscriber line intermediate line network. For example, one office uses a 2: 1 ratio while other offices use different ratios. A single relationship applies to the entire office. The program sequences, which depend on the concentration ratio of the office, are examples of programs used in the office on a mutually exclusive basis. It is possible to enter all these mutually exclusive programs in the general program location φ, but one

009 509/35

such allocation of storage space would be wasteful. Accordingly, in the case of extensive program sequences used in an office on a mutually exclusive basis, the appropriate sequences which meet the requirements of the office at the time of its establishment are entered into location φ of the program memory.

The information that clearly defines an office is divided into two general categories, namely parameters and so-called conversions. The individual, mutually exclusive Programs form the first element of the office parameters. Office transfers should be made with reference to the Locations (§) and φ of the program memory 202 are described.

In a telephone exchange, the traffic capacity of network 220 is a function of the Concentration ratio of the subscriber line link network 221. One office is only a single concentration ratio for all subscriber line-link networks assigned. Accordingly, the programs that locate a clear path through the subscriber line-link network and control of this network, uniquely determine when the office is set up. The program sequences, that of the concentration ratio of the subscriber line-link network depend are extraordinarily extensive. Therefore, a considerable amount of storage space can be left in program memory 202 by saving only the consequences that the prescribed concentration ratio are entered into the program memory 202. These program sequences are a good example of mutually exclusive program sequences.

Feature points

The general program in place (T) also contains many relatively short sequences of program command words that are used on a mutually exclusive basis in each office of a class. Since these sequences are short, little memory space would be saved by choosing the correct sequences when setting up the office and entering in location (2). The selection of such sequences is made with the help of jump commands called »feature points«, which are stored in location (3) of the program memory. An example of a feature that can be selected with the help of a feature point im'Ort (3) relates to the interpretation of a first "0" in a subscriber's dialing characters. In certain offices, if a subscriber dials or keys a "0" as the first digit, a call to the operator is intended. In other offices, however, the first »0« is followed by additional dialing digits that indicate a direct long-distance call from subscriber to subscriber. The call processing sequence, which interprets the registered dialing information, contains an unconditional jump command to an absolute address in location φ. In this absolute address, the program memory contains a further unconditional jump command to a corresponding absolute address in the location (J) of the program memory. This address in location φ contains the first command of the sequence that applies to the special office. That is, if a direct remote dialing from subscriber to subscriber is permitted in an office, a program sequence of the general program that contains this operating feature is reached via the jump command of the feature point. Similarly, if direct remote dialing from participant to participant is not a feature of the office, a program sequence that contains a connection to the placement officer is achieved in the general program. However, this is only one example of a feature which applies to the entire office and which can be reached with the aid of the feature points in the location (D of the program memory 202.

Equipment parameters

As already stated; a single general program applies for offices with many different physical properties. The physical Properties that are of interest to the following discussion are those that determine the size of the Define the office and its traffic capacity. The term "office size" used here relates the number of subscriber lines and trunk lines served by the office, and the expression "Traffic capacity" relates to the equipment that is provided to operate the subscriber lines and connecting lines. The following explanation does not contain a description of the features assigned to the subscriber lines and connection lines and Operating options, because these questions in ιοί-, under the heading »Implementations« be tert.

The information in the locations @ and (D of the program memory 202 is used to identify the information in the locations (S) and (c) of the conversation memory 203. However, there is no absolute correspondence between the information in the locations @ and (D and the Information is available in locations (S) and (£). The general programs contain program sequences called "recognition program sequences" and "balance program sequences". These program sequences contain commands to read data in location @ of the program memory. As shown in Fig. 6, the information in location @ as well as the information in locations (J) to (D are always in the same absolute address in program memory 202. The information in location @ contains references to data in location φ of the program memory in location (5) is required by the recognition sequence to generate the identification information to be stored in locations (S) and (c) of the conversation memory 203. The quantity dir in location (5) to be stored The saving data changes from office to office. Therefore, the location (D is not assigned the same fixed position in each office, and the number of assigned word positions changes from office to office. The information in place @ is used to find the identification _{data for the recognition and balance program sequences of the general program. Ilt}

There is no access to the data in the program storage locations for the call processing sequences @ and φ are required, as these data are only used to identify the information in the locations (S) and (£) des Call memory 203 ■ serve. The call processing sequences have direct access to the information in the location (S) of the conversation memory with the help of commands contained in these sequences are.

In this way, the program memory 202 always contains at least the outgoing registers are assigned two functionally equivalent program memories in the order in which they are released. The linked list and the conversation memory 203 always contain an entry with at least two functionally equivalent conversation words (start cell and end cell, FIG. 9), which are stored in the memory. The number of the program memory 202 and linked list is common, and the linking of the conversation memory 203 is a function of the entries, each individually for the to-be-office size and the traffic capacity, and the para- regulating elements (in this case outgoing remeter in place (p ) reflect this fact. The register) are provided. The entry with two can be seen in the following explanation. 20 words are located in the place (S) of the conversation. Memory 203.

to store data accumulated during the course of a call, and when the system is first put into service at 25, the initial cell entry in the record for the availability of location (S) identifies the first outgoing register as the one Equipment to be used on handling calls to be assigned next, and the end cells, or to save for fault conditions. An entry identifies the last outgoing register section of the memory that is to be stored as the last to be allocated. The collected data is used here, the "Register" 30 concatenation word (second word), renamed to the first. As will be explained further below, there are multiple registers assigned, the second specifies more types of registers, which are arranged in group registers as the one to be assigned next in location (c) in the conversation memory 203 after the first was occupied, and so are., An outgoing register provides an example of further, in numerical order for the remainder of the registers, used to accumulate data on the 35 items to be allocated. After the system is used while processing a call. Since all operation has been taken, the registers common organization of an outgoing register are occupied in different lengths of time, depending on the call memory 203 is shown in FIG. Each speed with which the subscriber Wählim-Amt contains a large number of outgoing registers, pulses, and depending on the relative and there are two conversation memory words available, 40 speed with which the central data processes all outgoing registers of the office of common calls produce and are accordingly resam. The two common words are gister can release. After that, the system is called the beginning cell word and the end cell word. The operation has been, a random Verket start cell word contains the address of the outgoing elements to be assigned. That is, the register that is to be allocated next and 45 elements to be allocated are no longer exactly where the end cell word contains the address of the outgoing - in a numerical order, but instead of the register that is to be allocated last. The register that is the next to be sent is always the register that is allocated in the order in which it is free. In other words, the register outgoing has been. This arrangement is therefore very much the one that has been free for the longest, if the Re- 5 ° is appropriate because all registers, even in periods with registers, which are to be allocated first. Which are commonly used - only very low traffic loads, including start cell and end cell inputs - are thus any disturbances that are shown in a in FIG. 9A. These entries are located in the register can occur in periods normal location (S) of the call memory 203, namely always traffic load determined, and not only then, at the same absolute memory addresses in all 55 when a very heavy traffic load occurs.

In this exemplary embodiment, a sent list contains the possibility that a single word pair The current register contains a block of 16 conversation words (Fig. 8), namely the starting cell and the ending memory words, which, according to FIG. 9B, is sufficient for each office of the class, and are net.

The central data processor 200 receives the line-link network 221 and four contain the scanner information via the transmission path 208 45 stages in the connecting line link, interprets them with the aid of a dialing signal from network 230.

The dial signal receiver registers comprise the three blocks shown and the concentration ratio of subscriber 8 C, 8 D and 8 E. The words 65 line-to-line network 221 reflected in these three blocks are designated with auxiliaries. Since the busy-free network plan changes with word 1, auxiliary word 2 and auxiliary word 3. With this on-traffic capacity, it is located in the location © order, the first auxiliary word (AW-I) contains the words of the conversation memory 203.

The transfers between the consequences of the general program, the consequences of the individual, themselves Mutually exclusive programs and the busy-free network plan are carried out with the help of Notes (point 2) that are located in location (S) of the call log 203. A word in place (S) is reserved for the maximum number of references required in the offices of this class. For example, if the maximum number of subscriber line-link networks allowed in If a certain class of offices is 16, then 16 word positions are reserved. This means that in A small number of word positions are reserved for the smaller offices of a class and are not used. However, this disadvantage is only small compared to the simple manner in which additional Network capacity can be added to the office, and compared to the overall saving of storage capacity. That is, with this arrangement, the busy-idle network map can have a Number of call memories are distributed and when a new network frame is added, only has to allocate memory space for this plan in place © of the conversation memory 203 and that for the new network frame in place (S) reserved reference word are brought up to date, to indicate the assignment in the place @.

In the case of the busy-free network plan, the storage space required for a network frame is relatively large. Savings can therefore be achieved by providing notices that enable the general program or the mutually exclusive program to be linked to the busy-free network plan. If the total memory space required for the largest office in a class is relatively small, the total space required to store this data in the location (S) can be reserved for the largest office in the class. The data for the dial signal scanning program belong to this group. In this embodiment, logical word locations are required for each group of 16 dial signal receivers. In addition, three common conversation memory words are required to operate all dial signal receivers of an office. The organization, _{v of} the data for the dialing signal scanning program,., Is shown schematically in FIG. 8 under 8B and 8G. In this embodiment, a scanner can query a group of 16 monitoring elements in parallel. Such a group of 16 elements is called a scanner line. The maximum number of dial-signal receivers in the special class of offices considered here is 256. Therefore, 16 scan lines are sufficient for this maximum number of dial-signal receivers.

In Fig. 8, scanner line addresses (CW1) are stored in a maximum of 16 word positions at 8B. The scanner line address defines both the scanner to which the line belongs and the particular line. In any given office, the associated scanner lines can only go to N. Therefore, the word positions in excess of N in the reserved block of 16 words are wasted. However, if the scan line addresses and other data for the dial signal scanning program were stored in location (C), notes in location (S) would be required. Not all of the words wasted in this arrangement would therefore be saved. In addition, the use of hints to read this data requires additional machine time. Since scanning is a high-speed repetitive function of the system, reducing the time required to execute the scan sequences is extremely important. The savings that are possible when entering the data for the dialing signal scanning program in place (£) are relatively small. Therefore these data are in place (S).

In the in Fig. 8 under 8B shown blocks of words Wl through W 5 is a word reserved for any Abtasterzeile analogous manner. However, only bit positions 0 to 15 of each word are used in these blocks. Within these bit positions, the first bit of each word is assigned to the first scanning element of the corresponding scanning line, the second bit position is assigned to the second element of the scanning line, etc. Consequently, in these word blocks, corresponding bit positions of corresponding lines are assigned to the same scanning element.

The data stored in block CW2 contain the address of the associated auxiliary words of the corresponding dial signal receiver registers. As indicated above, the dial receiver and dial receiver register are individually associated with each other. In FIG. 8, at 8B, a single line, for example the line "0", corresponds to each of the words W1 to, WS and CW1 to CW3 of a group of 16 dialing signal receivers. There are therefore 16 dial signal receiver registers (8C to 8E) assigned to each such line. The words AWl, AW 2 and AW3, which contain a dial signal receiver register, are in

48 consecutive words in the location (c) of the conversation memory 203. As a result, the word AW2-1 is 16 word positions away from the word AW 1-1, and the word AW 3-1 is a further 16 word positions away from the word AWl-I. This arrangement makes programming easier.

The data stored in block CW 3 in Fig. 8 under 8B contains a program return address. This means that when the selection signal scanning program is executed, a jump can be made to a sequence, for example in order to bring one of the above-described counters of the outgoing registers up to date. After the counter has been advanced, the data processor returns to the point indicated by the address,.! Stored in block CW3, to execute the dial signal scanning program. Again there is one word for each possible scan line.

In Fig. 8, under 8G, three common entries ADR1, ADR2 and SCN1 are shown. The sampling of dial signal receivers is carried out in time-ordered interruptions. Sampling must occur approximately every 10 milliseconds, and in the embodiment there are odd and even time-ordered interruptions. Successive odd interruptions occur at intervals of 10 milliseconds and accordingly also the successive even interruptions every 10 milliseconds. Odd and even interruptions occur at 5 millisecond intervals. In the embodiment, about half of the scan lines are in the odd breaks and the remaining half

summary

As stated above, there are defined classes of central office, and for each In the class of offices, a basic data processor compilation is provided as well as an amount of information, the "general program" and "general data" are named for this class of offices. The basic data processor set includes certain basic memory arrangements,, and within this arrangement are the general program and the general data for a given Class of offices always at the same absolute addresses within the memory.

Furthermore, as already explained, two offices cannot have all properties when setting up be identical, and furthermore, two offices are not enlarged in the same way. Hence will be According to the invention, the individual properties of each office by means of office parameters (under Inclusion of conversions). The exchange parameters and conversions are in the memory arrangement with the general program and the general data not mixed up. The parameters contain a number of data types which allow the general program to work with different Connect elements of the system that change from office to office. Change this data the content from office to office. However, they are always at identical addresses for everyone Offices of a class. For example, this data contains the following parts:

1. Start and end cells for register groups;

2. Notes on the network plan; '

3. data for the dial signal sampling program;

4. Indications of relocation start cells;
5 «!: Feature data. ..

With the help of parts 1, 2 and 4, the general program connect to functional memory blocks that are not part of the general program or Contain general data, and with the help of data from part 3, the general program with scanners contact, the number of which changes from office to office.

Similarly, the unit conversions in the @ area of the program memory give the general program the possibility of using different units of the system via the central impulse distributor, to connect the sampler and the signal distributors.
