Abstract

A distributor device for the telephone switching system is disposed directly in or on the latter. The distributor device has distributor components (4) which are provided with connection points (5) for the incoming subscriber lines (6) and outgoing jumper lines (8). The latter are passed to connection points (9) which are disposed on the front of slot-in modules (1) of the switching system. The number of distributor modules and connection points is reduced due to the direct connection of the jumper lines (8) to the assemblies (1) containing the subscriber connections. <IMAGE>

Description

Telephone switching facility

The invention relates to a telephone exchange with at least one frame for holding slide-in electrical assemblies and at least one distribution device.

By the company publication Siemens Telcom Report 2 (1979), supplement "Telephone system EMS ", page 34, column 2 below it is known to have a distributor for a smaller To install the telephone exchange in the upper part of a cabinet frame.

The German Offenlegungsschrift 29 01 678 also provides a distributor known for such a system, in which pluggable patch cords between the lines coming from the subscriber and those leading to the switching facilities Provide lines.

In public offices it is customary to place the distribution facilities in to be arranged in separate rooms. The distribution facility is divided into an office and a participant side. The jumper wires run here between distribution elements, which are connected to the subscriber lines and distribution elements to which the lines leading to the switching facilities are connected.

The invention is based on the object of a switching system to create in which the distribution and wiring effort is reduced.

This object is achieved by the invention according to claim 1. By the invention is achieved that the distribution modules on the switching side of the distributor as well as the connection cables from the distributor to the switching devices the switching system are omitted. This reduces the number of joints in the lines between the subscriber cables and the switching devices. The shunting lines are connected directly to the associated assemblies. This is made easier by that the assemblies of the switching devices are provided with subscriber circuits. This means that in each case the lines assigned to a subscriber up to the module can be laid out together. The remaining ones, with the subscriber lines connected distribution modules contain all options for separating connections or for connection to individual lines. In addition, these distribution modules the protection modules, e.g. against overvoltages, assigned. Changes a participant its location, a patch cord can be assigned by its number Module to be relocated to another subscriber line that to his new one Location leads. Such a routing can be done in a similar way as before within of the distributor.

Advantageous developments of the invention are in the claims 2 to 8 characterized: Through the development according to claim 2 is for the distributor modules no installation space required for assemblies.

The jumper lines can be laid so that they do the work do not interfere with the distributor.

Through the development according to claim 3, the jumper lines from the distributor modules to the assemblies clearly laid out on one level will.

Through the development according to claim 4, the distributor blocks Can be installed in a space-saving manner in the frame, which also accommodates the assemblies. the Patch cables can then be placed on the rear of the frame via a shared wiring wall be relocated.

The development according to claim 5 makes it possible that the jumper lines on the operating side of the frame for receiving the assemblies brought up to these can be. The connection elements are particularly easily accessible for maneuvering work. The connection elements can be designed, for example, as solderless insulation displacement terminals which make a simple, quick and safe connection and disconnection possible.

The development according to claim 6 requires a higher effort on contact parts, but makes maneuvering easier.

The development according to claim 7 prevents the jumper wires run unguided and disordered on the front of the frame.

Through the development according to claim 8, the front of the frame kept free of jumper lines, which makes the other service work easier.

In the following, the invention is illustrated by means of one in the drawing Embodiment explained in more detail.

Fig. 1 shows a schematic perspective view of a part a telephone exchange, FIG. 2 shows a section of the telephone exchange according to Fig. 1.

1 and 2 are flat electrical assemblies 1 in a frame arranged above and next to each other. The arrow A indicates the direction on, from which the assemblies 1 are pushed in from the front of the frame. One Side wall 2 of the frame laterally delimits the slide-in space.

On the outside of the side wall 2 there are support plates 3 for distribution modules 4 attached. The distribution modules 4 have connection points 5 for incoming subscriber lines 6 that emerge from shift cables 7. The distribution modules 4 are with further Connection elements 5 for outgoing jumper lines 8 are provided. These lead to connection points 9 on the front of the modules 1, which are provided with the subscriber circuits are.

The connection points 5 and / or 9 can be designed as insulation displacement terminals, for example to which the insulated wire is connected by a simple push-in process can be. As shown in Fig. 2, such insulation displacement terminals can directly be attached to the circuit boards of the assemblies 1. Such insulation displacement terminals enable a multiple contacting of a jumper wire in a simple manner maneuvering favors.

The distributor modules 4 are flat next to one another on the carrier plate 3 arranged and can contain modules e.g. for protection against overvoltages. In the case of larger switching systems, the distributor modules can be placed on both side walls of the frame.
