Abstract

In the basic connection of a transmission field with at least seven busbars, the number of devices connected to the transmission field is equal to the number of busbars in the transmission field. The devices are connected to the first output of all busbars and the other busbar outputs are connected to these devices in cyclic tandems with seven outputs and six jumpers. In the basic connection of a transmission field with six busbars, the number of devices connected is equal to twice the number of busbars in the transmission field and the devices are connected to the first and third outputs of all busbars. In the basic connection of a transmission field with at least four and at most five busbars, the number of devices connected is equal to three times the number of busbars in the transmission field and the devices are connected to the first, third and fifth outputs of all busbars. The other busbar outputs are connected to these devices in cyclic tandems, the number of which is equal to the number of devices connected to the transmission field. From the basic connection, the connection of the transmission field is derived with the same number of busbars, but with a larger number of connected devices. From the basic connection of the transmission field, jumpers in tandems are gradually omitted and to the east, which is the beginning of the separate part of the tandem, another device is connected.

Description

The invention relates to the connection of transmission fields in a telephone exchange at the outlets of a busbar group comprising at least four busbars each having seven exits.

In a PABX, some devices are centralized to a group of devices and connect through the group of busbars to other PABX devices when their collaboration is needed to establish a connection in the PABX. The busbar group has entrances and exits. Other PBX devices are permanently connected to the inputs. All exits in the group are permanently connected to the exits in the gearbox. If necessary, the busbar searches for a free device connected at one of its exits and connects the device to the input after which the device connection request came.

The busbar searches for free equipment, for example, by examining all of its exits and testing on each of them whether the free device is connected to the east, often searching for exits with a smaller serial number in the busbar. This implies that exits with a smaller serial number in the busbar are more frequently occupied than exits with a larger serial number.

The number of busbar group exits is generally greater than the number of devices connected.

Therefore, on average, several busbar group exits are permanently connected to one device. This connection takes place in the transmission field. Each busbar has the same number of exits in the transmission field. The number of busbars in the transmission field and the number of exits from one busbar indicate the size of the transmission field.

The transmission field contains busbar group exits and jumpers between the exits. The jumper is the wire connection of the two exits of the transmission field. The jumpers connected in series consist of tandem. Tandem has a start in the east to which the device is connected. The gearbox is mounted on the side of the intermediate distributor fitted with vertical pointed tapes. The busbar group exits are connected to the tips. Gearbox jumpers are mounted between the tips.

At some of these peaks, the device is permanently connected.

The following demands are placed on a good transmission field:

- good operational throughput for equipment connection requirements as the ability to provide as many free equipment involved as possible at the exits of each busbar,

- easy design in projection,

- regular involvement,

- economy in material consumption,

- the possibility of relatively simple changes to the transmission field without impairing its good operational throughput.

Good throughput is the most important feature of the transmission field. Due to the above-described uneven occupancy of individual busbars exits in the transmission field, a suitable escalation is a decisive factor in the good operational throughput of the transmission field, in that multiple traffic exits are connected to the device either individually or less per unit. exits less loaded. The operational throughput of the transmission field improves 1 uniform interconnection of the individual busbars with each other.

The transmission field is easier to design if a simple design methodology and various graphical aids are developed. Regular wiring of the transmission field is beneficial for installation and maintenance work, as it facilitates schematic orientation and realization of the transmission field. The employees involved are better remembered and do not often need to consult the documentation. The transmission field is economical in material consumption if the sum of the lengths of all jumpers in the transmission field is as small as possible. Easily making changes to the transmission field is a very important requirement for the transmission field, since these changes are made quite often due to changes in the telephone network. It is desirable that as many jumpers remain as possible when changing the transmission field. From the design of the transmission field it should be obvious the order of mounting of jumpers so that jumpers do not interfere with the removal of some of them in order to increase the number of connected devices in the group.

Changes in the transmission field must not reduce its throughput. These requirements for the transmission field contradict each other, so the design of the transmission field is always a compromise, i

The main disadvantages of the existing transmission fields are that they were designed individually only according to their parameters - the number of busbars, the number of busbars and the number of devices in the group. Transmission fields of similar or even identical parameters often had significantly different connections. In order to ensure good operational throughput of the transmission field, the design principles of uniformity in the interconnection of the individual busbars should be respected. However, the design was not examined by computer modeling, so the actual throughput of the proposed transmission field was only hypothetical. Gearbox design was laborious. Although designers were careful about the wiring of the gearbox, the design was relatively easy to make in the future, as the design field was not up to date. It was difficult to control the economy in material consumption. The mounting of the gearbox on the intermediate switchgear was complicated by the fact that each gearbox had a different connection and the order of mounting of the jumpers in the gearbox was not prescribed with respect to changes. Similar difficulties were encountered in the maintenance of operated transmission fields in the control panel. Repeated changes in the operated transmission field generally led to a gradual deterioration in its operational throughput, as it was not viable to remodel the entire transmission field due to a small change in the group of devices.

The aforementioned disadvantages are overcome by the connection of the transmission fields according to the invention, which consists in that in a transmission field with at least seven busbars to which a number of devices equal to the number of busbars in the transmission field is connected, the other gearbox exits are connected to these devices in a number of tandem busbars starting at the first exit of all busbars and repeating cyclically on individual busbars, the last busbars in the gearbox being considered adjacent to the first busbars. In a six-busbar transmission field with twelve devices connected, six devices are connected to the first exit of all busbars and the second exit of all busbars is connected to these devices in six identical tandems starting at the first exit of all busbars and repeating cyclically on individual busbars wherein the last busbar in the transmission field is considered adjacent to the first busbar. the remaining six devices are connected to the third exit of all busbars, and the fourth to seventh exit of all busbars are connected to these devices in six identical tandems starting at the third exit of all busbars and cycling cyclically on individual busbars. adjacent first busbar. In a transmission array with at least four to a maximum of five busbars that have a number of devices equal to three times the number of busbars in the transmission array, a number of devices equal to the number of busbars in the transmission array is connected to the first exit of all busbars and in the number of busbars identical in tandem, starting at the first exit of all busbars and repeating cyclically on individual busbars, the last busbars in the transmission field being considered adjacent to the first busbars. A further number of devices equal to the number of busbars in the transmission field is connected to the third exit of all busbars and the fourth exit of all busbars is connected to these devices in the number of busbars of identical tandem starting at the third exit of all busbars the busbar in the transmission field is considered to be adjacent to the first busbar. The remaining number of devices, equal to the number of busbars in the transmission array, is connected to the fifth exit of all busbars and the sixth to seventh exit of all busbars are connected to these devices in the number of busbars identical to tandems starting at the fifth exit of all busbars in the transmission field. individual busbars, the last busbar in the transmission field being considered adjacent to the first busbar.

Transmission array with at least seven busbars with a number of devices connected equal to the number of busbars in a transmission field and transmission array with six busbars with 12 devices connected and a transmission array with at least four to a maximum of five busbars with a number of devices according to the invention, they are the basic circuit from which the transmission fields are connected with the same number of busbars but with a plurality of devices connected to the transmission field.

This derivation consists in the fact that with increasing number of devices connected to the transmission field, the first jumper of all tandems in the transmission field, then the second jumper of all tandems, etc. up to the sixth jumper of all tandems in the transmission field are gradually omitted. Jumpers with the same serial number for different tandems are omitted evenly across the transmission field. One device is connected to the east, which is the beginning of a separate part of the tandem.

The main advantages of the invention are that the connection of the transmission fields according to the invention comprises most of the transmission fields on a group of busbars of the type mentioned above, which may occur in practice. Each transmission field is well operable, which is achieved by a relatively uniform interconnection of the individual busbars with each other. The gearboxes have a regular and well-arranged wiring that facilitates assembly work and maintenance. They are economical in material consumption.

The even greater effect of engaging the transmission fields according to the invention is achieved by the fact that all transmission fields form a uniform wiring system. They are similar to each other, so that the change of one transmission field to another is made with a minimum of changes in the wiring of the existing transmission field and without a noticeable change in good throughput. The assembly work in case of changes in the transmission field is also facilitated by the fact that in the transmission fields according to the invention it is possible to prescribe the assembly order of individual jumpers, which is the opposite order of their possible omission while increasing the number of devices connected to the transmission field. Cyclicity in the connection of the transmission fields according to the invention facilitates a change in the number of busbars in the transmission field - the jumpers are removed only between the first and last busbars in the transmission field and the added busbars are connected to the cyclic connection of the other jumpers.

All transmission fields can be pre-processed into a catalog from which the designer draws his particular transmission field into the project. The catalog simplifies the transmission field documentation. The catalog will enable machine processing of the design of the gearbox as well as elaboration of its laborious documentation on the computer, flawlessly and in the final graphic design into the project. When you prepare your gearbox documentation, your computer application will help extend this documentation with additional information that speeds up assembly and maintenance work. Administrative and researchers will find in the catalog, for study purposes, the involvement of transmission fields that have not yet been designed.
