Device for optimizing the circuit switching capacity of a switching center
View Patent ↗The invention relates to a device for circuit switching connections, which are led outside a switching center, with a plurality of peripheral devices that can be addressed under a common HW address by the message distribution system of the switching center. According to the invention, each of the peripheral devices comprises its own logical address, and a splitting up of the peripheral devices into real peripheral devices, which represent the previously mentioned HW address, and into virtual peripheral devices is given. The invention is characterized in that the logical addresses of the peripheral devices, which are used exclusively for controlling connections led outside of the switching center, are located in areas of the switching network that are not expanded into hardware, whereby a virtual switching network unit is defined, and a splitting up of the switching network into real and virtual switching network units is carried out.
1. A device for switching through connections carried outside a switching center, comprising:
a plurality of peripheral devices which can be addressed under a common hardware address by a message distribution system of the switching center, each of the peripheral devices having a corresponding logical address, and the peripheral devices being split into real devices corresponding to the hardware address; and virtual peripheral devices, wherein
the logical addresses of the peripheral devices that are used exclusively for connection control of connections carried outside the switching center lie in regions of a coupling network that are not extended as hardware, thereby defining a virtual coupling network unit, and thereby splitting the coupling network into real and virtual coupling network units.
2. The device as recited in claim 1 , wherein the logical addresses of the peripheral devices that are used exclusively for connection control of connections carried outside the switching center lie in regions of the message distribution system that are not extended as hardware, thereby defining a virtual message distribution system, and thereby splitting the message distribution system into real and virtual message distribution system units.
3. The device as recited in claim 1 , wherein extension of a switching center is carried out in accordance with the totality of the virtual and real peripheral devices using a plurality of hardware addresses.
4. The device as recited in claim 1 , wherein sub-units of the coupling network and/or the message distribution system that are not extended as a result of their assignment to peripheral devices for connection control of connections carried outside the switching center are set up explicitly as virtual components through a user interface or implicitly kept and indicated as such in the database.
5. The device as recited in claim 1 , wherein a virtual attribute is included at the user interface as an optional parameter of an operating command for virtualizable portions of the coupling network and/or message distribution system.
6. The device as recited in claim 5 , wherein when setting up virtualizable components of the coupling network and the message distribution system, the virtualizable components can be made plausible against the real and virtual components that have already been set up by the administrative software at the switching center to prevent an incorrect operation.
7. The device as recited in claim 1 , wherein during a first startup and a fault clearing of the coupling network and the message distribution system, startup of virtual components of the coupling network and the message distributor is suppressed in operation technology software at the switching center.
8. The device as recited in claim 1 , wherein virtual portions of the coupling network and the message distribution system are marked as being virtual in the switching center output that serves for fault clearing, to avoid erroneous fault clearing of non-existent components.
