DE2912764C3 - Method for centrally controlled telecommunications switching systems, in particular telephone branch exchange switching systems, with switching stations - Google Patents

Description

Process for centrally controlled telecommunication switching systems, in particular telephone private branch exchanges, with a speech path coupling network '"' plant and with the exchange of switching-related data, addresses and control commands used for establishing connections via the speech path coupling network, between separate sub-controls ^b0 provided for different tasks and with several implemented as switching stations operation telephones with the same operating mode (official extension switching and signaling mode), wherein further on the switched network, each present connection line ^hl with each Bedienungsfern- speaker is connected, and wherein each switching space thus formed a centrally located, ilen instantaneous state (in service / out Operation) of the switching station, characteristic status memory is assigned.

There is already a circuit arrangement (DE-AS 26 47 404) known in which in an aforementioned Centrally controlled telephone extension switching system service telephones are provided, with the help of which the individual switching procedures can be carried out. All have service telephones the same operating mode, i.e. there is no separation of the different types of calls their feed to the individual service telephones made.

It is also known (DE-AS 15 62 232), each of the individual switching stations one centrally located Allocate storage space in which the current status (e.g. occupied-free) of the attendant console is stored

The object of the invention is to provide a method with the help of such a Telephone extension switching system with several switchboards by a measure of Operators can take over the individual operator stations different tasks, whereby however, it must be ensured that everyone in the telephone exchange switching system is in principle at all times provided switching services are feasible.

This is achieved by also storing the operating mode (BA 0, BAi, BA 2) of the associated attendant console in the respective status memory, so that each attendant console (VPL 1 to VPL 10) in the "out of service" state has all other operating modes ( BA 1, BA 2) including operating mode (BAO) is assigned, whereby this operating mode (BA 0) after commissioning of the operator console (VPL 1 to VPL 10) by the operator in any other operating mode provided in the system (BA 1, BA 2) can be changed after a comparison of the status memory contents of all switching stations made by a change incentive (e.g. VSPA) has shown that after the intended change in operating mode, all switching services provided in the private branch exchange switching system can still be performed by the entirety of the switching stations.

This has the advantage that the individual operators at the operator station Modifications of operating modes and thus changes to the tasks of the individual attendant consoles made can be without the operation of the system is disrupted or without the originally for the Private branch exchange switching system provided switching services are restricted.,

A further development of the method according to the invention is that when carrying out a Change of operating mode all the newly selected operating mode including among other things the operating modes of the other attendant consoles are automatically changed so that they no longer use the newly selected operating mode contain.

This has the advantage that after an operating mode selected for a switchboard, all switching services relating to this operating mode only at this switching station or at a switching station, for which this operating mode has already been selected before.

The method according to the invention will be explained below using a simple example. Diibei

only three different operating modes are listed, each of which can be given in two different states.

The BAO operating mode means universal attendant console (the attendant console can be assigned all types of calls).

Operating mode BA 1 means an exchange (the attendant is only assigned exchange calls). The operating mode BA 2 means reporting and advisory shuttles (the attendant console is only assigned notification and advisory calls). For the different operational states, for the sake of simplicity, only:

1. Operator station out of order and

2. Operator station in operation

thought

This results in the following six possible ones operational characteristics of an attendant console:

01 = operator station out of order in operating mode

BAO
11 = attendant console in operation in operating mode

15th

02 = operator station out of order in operating mode

BAi

12 = attendant console in operation in operating mode

BAX

03 = operator station out of order in operating mode

BA 2

13 = attendant console in operation in operating mode

BA 2

Operational incentives such as "plug in the jack" = VK, "pull the jack η " = VK, VSPA = block attendant for incoming outside calls and V-SPA = unblock for incoming outside calls can be assigned to the attendant consoles. In addition, the example shown shows two indirect incentives that result from the method according to the invention. The indirect incentives are:

1. iVBO = all attendant places compulsorily in

switch to operating mode BA 0 and

2. iVB 1 = all attendant places with the '

Switch between operating mode BAO and operating mode BA 1.

For a better understanding of the method according to the invention, the F i «j. 1 to 3 shown, in which the v> switching stations VPL 1 to VPL 10 are indicated. The circles within the attendant consoles indicate the operating status that is stored in the attendant's state memory prior to a change request. The circles outside the attendant consoles indicate the operating state in which an attendant console is brought by operational incentives (operator) or indirect incentives can be. The designations VPLx to VPLx " only indicate other possible mines.

In FIG. 2 the switching boards / .e VPLA, VPL 2 and VPL 3 are shown. Before the attendant consoles were put into operation, all attendant consoles were set to operating mode 01 - that is, attendant console h-, with operating mode Βλ 0 out of order. In the example according to F ·. G. 1, attendant console VPL I is still in operating mode 01, while attendant consoles VPL 2 and VPL 3 are in state 11 - that is, operating mode BA 0 in the operating state. It is assumed that the switchboards are connected to each other (VK = "jack plugged") and that the operator at switchboard 2 is aiming for state 13 (operating mode BA 2 in the operating state = switchboard only receives message and advice calls) the incentive VSPA (block operator position for incoming exchange calls) is given. Since the operating mode BAO in the present example consists of the operating modes BA 1 and BA 2 and since another attendant console (VPL 3) has stored state 11 in its status memory, the operator can change the operating mode at the attendant console VPL 2. State 13 is now stored in its state memory, while all the others have state 01 or

11 switching stations (VPLi, VPL 3, VPLx) inevitably to state 02 (operating mode BA '■■ out of service) or through the indirect incentive iVB \

12 (operating mode BAQ in the operating area and). This change in the operating status of the attendant consoles VPL 1, VPL 2 and VPLx is necessary, since otherwise not only the attendant console VPL 2 will receive the avoidance and advisory calls.

In FIG. 1 the pulling of the handle is shown for attendant console VPL 2 (attendant console goes out of operation) (VK). In this case, the operator console VPL 2 goes into operating state 01, since the operator console VPL 3 or VPLx can take over all switching services.

Assuming that only the two attendant consoles VPLi and VPL 2 (i.e. only one attendant console in state 11) are available at the time of the change request, or that only attendant console VPL 2 is in operation, then VSPA will be available for all attendant consoles due to the incentive given the indirect incentive / VBO result. As a result, all switching stations would forcibly adopt the SAO operating mode and the switching station VPL 2 could do justice to all switching services. In the other case, while the switching services could no longer be carried out in operating mode BA 1.

The F i g. 2 shows the attendant console VPL 4 in state 02 (operating mode BA 1 out of service) and the attendant consoles VPL5 / VPLS each with operating state 12 (operating mode BA i in operating state). Such a coincidence of states is in and of itself only possible if a further switching station with operating state 13 has previously gone out of operation. Since the attendant console VFL 4 is also out of service and only attendant consoles with status 12 are in operation, the indirect incentive / VBO inevitably occurs according to the invention, which switches all attendant consoles to operating mode BA 0. The operator console VPL 4 thus receives state 01 and the other attendant consoles state 11. If the operator at the operator console VPL 5 wishes to switch to state I 3 before switching off the attendant console ( not shown) with state 11 by issuing the VSPA incentive, the operator console retains VPL 4 gets its state 02, the attendant console VPL 6 its state 12 and the attendant console VPL 5 receives the state 13. The attendant console, not shown, receives the indirect incentive iVB 1 before it is switched off and thus becomes

placed in state 12. This prevents a further rental station from being allocated notification and house calls.

There would only be one attendant console (VPL 5) with status 12 ( i.e. no attendant console VPL6). then if the attendant console VPL 5 attempted to reach state 13, if the additional attendant console had already been switched off, this would result from the indirect incentive iVBO at the attendant console. VPL 4 a changeover to state O1 and a changeover to state 11 at the operator console VPL 5. When the latch (VK) is pulled and the attendant console VPLb is present, the attendant console VPL 5 changes to state 02.

The F i g. 3 shows three switching stations VPL 7. VPLS and VPL 9 with the states 03, 13 and 13. Furthermore, a switching station VPL 10 with the state 12 is indicated. The state 03 of the Ver mitt jijnpcnlat7PC 7 hr ^ aut. Hatred for riip.sen dip retriehsart BA 2 provided, but it is not in operation. The attendant consoles VPL 8 and VPL 9 correspond to operating mode BA 2 in the operating state. If the attendant console VPL 10 is initially disregarded, then all attendant consoles 7, 8 and 9 were switched to operating mode BA 0 by the indirect incentive iVBO, with attendant console VPL 7 operating in operating mode 01 and the Both switchboards VPL 8 and VPL 9 receive operating mode 11. For example, the switching center VPZ. 8 go to state 12 by issuing the V-SPA (unblock outside calls). The attendant console VPL 10 would remain in state 12 and the attendant console VPL 7 goes to state 02 over (indirect incentive V01).

If the attendant console VPL 8 were to be used in accordance with FIG. 3 switch off (VK), then it receives state 03.

From the above it can be seen that the process according to the invention can be used in a simple manner it is possible to assign different operating modes (tasks) to the individual switching stations when there are several switching stations in a centrally controlled telephone extension switching system, whereby it is ensured that an attempt to change an operating mode is only allowed if all of the System underlying switching services is guaranteed. Another indirect incentive switching stations can also be forcibly put into operation or a night station, for example with status 11, then forced into operation are set when the existing attendant places in operation are no longer sufficient to process the attendant traffic.

In addition, lamps are provided at each switching station, which, for example, indicate the operating mode and the operating status. This can be B. be a SPA lamp that lights up to indicate state 12 (operating mode BA 1 in the operating state, ie the operator station is only assigned external calls). Since the? RfindungsgemäBe method is not limited to the above conditions, such a lamp, for example, a VSP lamp could be engaged in the corresponding mode, the Vorsperrung a switchboard indicative sub Vorsperrung is understood to mean that 1 no further example, in the mode BA Outside calls are accepted, but the pending outside calls are still being processed.
