Abstract
A circuit arrangement for switching PCM channels conducting baseband data signals, with serial data to be switched arriving at n input ports and being converted in blocks to parallel form, intermediately stored in a memory and converted to serial form again after read-out to be fed to n output ports each assigned to one or a plurality of destination addresses. The parallel data blocks are intermediately stored the first time in n input registers assigned to the n input ports. Thereafter, a second intermediate storage takes place in a RAM memory in such a manner that the data blocks are written in successively according to the sequence in which they arrived at a memory address which is counted up sequentially, or the data are subsequently intermediately stored in a RAM memory at a memory address which corresponds to the respective destination address. The data blocks are read out according to the number of the output port contained in the destination address or assigned to the destination address or according to their time position and are again intermediately stored in n output registers which are assigned to the respective n output ports.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
