    • In a method and network component of a communications network for switching connections of low bit rate between input modules and output modules, the input modules and the output modules form a first switching level, and an ATM switching stage arranged between the input modules and the output modules forms a second switching level. In the first switching level, a number of low bit rate connections at the input module, which are to be transmitted to the same output module, are respectively merged by the input module into at least one ATM connection. In the second switching level, the switching through of the ATM connections for transmitting data in ATM cells ensues by the ATM switching stage. Subsequently, in the first switching level, the ATM connections which have been switched through are converted by the output module into the low bit rate connections. The combined switching in two switching levels represents an especially economical solution for functions specific to mobile radio and switching applications dealing with low bitrate traffic, by simultaneously assuring an acceptable speech quality with good exploitation of the ATM bandwidth.
    • 在用于在输入模块和输出模块之间切换低比特率的连接的通信网络的方法和网络组件中,输入模块和输出模块形成第一开关级别,以及布置在输入模块和输出端之间的ATM切换级 模块形成第二个开关电平。 在第一切换级别中,要传输到同一输出模块的输入模块处的多个低比特率连接分别由输入模块合并成至少一个ATM连接。 在第二切换级别中,ATM信元的ATM连接的切换通过ATM交换阶段进行。 随后,在第一交换级别中,已经切换的ATM连接被输出模块转换成低比特率连接。 两个交换级别的组合切换代表了一种特别适用于处理低比特率流量的移动无线电和交换应用的功能的特别经济的解决方案,同时通过良好利用ATM带宽来确保可接受的语音质量。

    • A method and apparatus for coupling an ATM communication layer to a plurality of N mutually time-independent time-division multiplex communication terminals having an overall payload cell rate CRN which involves: generating a control signal sequence with a clock rate corresponding to the overall payload cell rate CRN of the N time-division multiplex communication terminals, whereby the control signals can represent a first or a second status; offering a fixed data pattern; transmitting the ATM cells coming from the ATM communication layer into an ATM cell waiting list; transmitting, on demand, an ATM cell from the ATM waiting list to the requesting time-division multiplex communication terminal when the respectively oldest control signal of the control signal sequence represents the first status, and transmitting the fixed data pattern to the requesting time-division multiplex communication terminal when the oldest control signal of the control signal sequence represents the second status; and deleting the oldest control signal of the control signal sequence. The method enables a frictionless coupling of an ATM communication layer having a plurality of mutually independent time-division multiplex communication terminals, whereby variable data rates (burst behavior) of the ATM layer as well as of the time-division multiplex communication terminals can be decoupled from one another and good cell delay variation (CDV) properties can be assured.

    • The invention relates to a hydraulic brake system of a vehicle comprising one wheel brake valve preceding each wheel brake cylinder and one return feed pump connected parallel to each of the wheel brake valves and connected to the suction sides of the wheel brake cylinders. For anti-lock control, the return feed pump is put into operation, and by clocked triggering of a wheel brake valve of a vehicle wheel that is tending to lock, the brake fluid pressure in the wheel brake cylinder of this vehicle wheel is modulated. To realize a traction control device, the invention sets forth a switchover valve in a brake line from the master brake cylinder to the wheel brake cylinder of a driven vehicle wheel. By closing the switchover valves and driving the return feed pump brake fluid can be aspirated from the master brake cylinder by the wheel brake valve of the non-driven vehicle wheel and pumped into the wheel brake cylinder of the driven vehicle wheel, and by this feed pump a brake force can be generated in order to avert spinning of the vehicle wheel.
