The invention relates to an arrangement adapted for use in switching equipment which is included in a telecommunications system, wherein the switching equipment includes, among other things, a number of incoming connections (4) that can be coupled via first coupling units (3); a number of outgoing connections (4a) that can be connected via second coupling units (3a);

Switching equipment arrangement

A signal transmission system includes one or more signal transmitting units, one or more signal receiving units and a medium adapted for the transmission of selected signals. A transmitted signal carries a number of signal elements which have been allocated to the same or different categories. A number of signal elements that have been allocated to the same category can be coordinated in a receiving unit to form predetermined information. The system includes a unit to increase the number of signal elements that have been allocated to one category (CTS) at the cost of the number of signal elements that have been allocated to another category (DTS) and/or a third category, and so on, or alternatively to carry out one or more selected functions within equipment connected to the receiving unit.

A method for distincting between at least two types of time slots in serial digital bit streams that are transmitted over a link between a transmitter and a receiver and that derive from the streams of parallel data bits which are delivered to the transmitter via an interface and subjected to parallel-series conversion in the transmitter. Subsequent to analyzing the parallel data bits in a time slot, the type of category to which this time slot belongs is decided and a plurality of marker bits are then inserted into the serial time slots, so as to obtain good transmission properties and also be restore the time slots to a parallel form. More specifically, the time slot categories are mutually separated with the aid of a different number of marker bits in the time slot, all of these marker bits having been assigned the inverted value of a bit other than the marker bits.
