Patent EP-0304998-A2 (EP)
Inventor: VAN DE MORTEL PETRUS PAULUS
IPC: H04W84/10
Filed: 1988-08-18
Abstract: A PABX cordless telephone system comprising a base station (10) and a plurality of handset (HS1 to HS5). The base station is connected to the public switching network and communicates with each handset by way of a respective duplex radio link. The operation of the PABX system is controlled by a micro-controller (16) in the base station. Micro-controllers are also present in each of the handsets. Security in the radio communication  via  the duplex radio links is provided by assigning an n-bit security address code, where n for example comprises 16 bits, to each handset. The signalling protocols in setting-up calls require the transmission of the full n-bit security code. In the interim periods the base station (10) carries out a security check on the handsets forming its system. Time, memory capacity in the micro-controllers and battery current can be saved whilst simultaneously achieving a high degree of security if the security check is carried out using m bits of the security codes where m < n and is typically equal to 8.

Abstract: If plesiochronous digital signals are processed with one another in a higher- or lower-level device, they must be adapted to the clock of this device. This is done by positive stuffing or destuffing, respectively. For this purpose, the digital signal to be adapted is entered into a variable-capacity store and then read out again. At high bit rates, the variable-capacity store must be embodied in a circuit system having short switching times. It is the object of the invention to specify a method and a circuit arrangement which are capable of processing digital signals at high bit rate. The serial bit sequence which forms the digital signal to be adapted is first converted into m parallel bit sequences. The parallel data words thus obtained, consisting of m bits, are stored in a store. For the adaptation, less than m bits are read out and, together with or without stuffing bits, combined to form a new parallel data word with m bits and parallel/serially converted. Stuffing and destuffing of plesiochronous digital signals. <IMAGE>
