    Abstract: A network element with equipment protection has first and second redundant signal paths for first and second redundant signals; a selector for selecting either of the two redundant signals as active; and first and second transition monitors coupled to the first and second signal paths, respectively, for monitoring the first and second signals for bit level transitions. The selector is controlled by the transition monitors to alter selection in the case that the selected signal does not contain bit level transitions while the non-selected signal does.

    Abstract: In order to provide a network element for switching time-division multiplex signals in a transport network, which allows higher capacity at moderate equipment costs, the network element has a number of input ports (I; IO1-IO8), a number of output ports (O; IO1-IO8) and a switch fabric ( ) SF; 58) interconnecting the input and output ports (IO1-IO8). The switching fabric ( ) SF; 58) is a cell based switch comprising one or more switch modules ( ) SE1-SEn) which are adapted to switch fixed-length cells on the basis of addresses contained in cell headers of the cells. The input ports (I) contain a segmentation device (11) for segmenting an input time-division multiplex signal into fixed-length cells and assigning address information to each cell. The output ports (O) contain a reassembly device (14) for reassembling cells received from said switch fabric (SF; 58) into an output time-division multiplex signal. The address information contains a fabric address (H1, H2) and a TDM address (P0, P1). The switch fabric switches the cells in accordance with the fabric address (H1, H2) to a corresponding output port (O) and the reassembly device (14) reassembles the cells in accordance with the TDM address (P0, P1).

    Abstract: A method of synchronizing at least one receiver module (MOD 1, MOD2), in particular a receiver module in a telecommunications network or in a network device of a telecommunications network, has the following steps: A first clock signal (TS 1) and a second clock signal (TS2) are sent to the at least one receiver module (MOD 1, MOD2). In addition, at least one item of master-slave-status information (MSX) about the at least one first clock signal (TS1) and/or the second clock signal (TS2) is sent to the at least one receiver module (MOD1, MOD2). Based on the item of master-slave-status information (MSX), the at least one receiver module (MOD 1, MOD2) selects the first clock signal (TS 1) or the second clock signal (TS2) as master synchronization signal for its synchronization.

    Abstract: In a data transmission system, a switching network in a connection node (VK) includes switch groups (SCH) for switching channels, which are each assigned to one or more time slots within the framework of a multiplex time signal, e.g. virtual containers of a STM-1 frame according to CCITT recommendations G707 to G.709. Each switch group (SCH) is modular and linked to one another, and contains a memory (DS) with several independently readable memory outputs (SA1 to SA4), through which the storage area can be accessed. Each part signal of a respective memory address can be connected with a data output of the switch group (SCH) through selectors (SEL1 to SEL4). A connecting memory (VB1 to VB4) controls the reading of each part signal from the memory (DS) to a memory output (SA1 to SA4) and a selector (SEL1 to SEL4). A coupling field may be composed of switch groups (SCH) arranged in columns and lines, as required. Each data outputs (DA1 to DA4) of one switch group (SCH MN) is connected to a connection input (VE1 to VE4) of the following switch group.

    Abstract: A synchronous transmission system is disclosed in which the transmission paths (leased lines) extend over several individual transmission systems (Sx). Monitoring devices (NIM) with access to at least one byte of the control data area are provided in synchronous transmission systems to write data into or read data out of the control data area. The monitoring devices (NIM) may thus be controlled and monitored by a signal source (S1).
