A shared protection span (18ab) is coupled between pairs of shared network elements (12a and 12b).

摘要： An apparatus and a method for cross connect matrices includes originating, center and terminating stages in both a main portion and a back-up portion that allows center stages to be switched without causing a framing error. The signal from the main portion is transmitted through both the back-up and main portions of the cross connect matrices such that a terminating line card receives a frame aligned signal from the main and back portions. The terminating line card then switches its output to be the signal produced by the back-up portion with no framing error. In the main portion, the center stage may be switched. After the center stage is switched, the terminating line card can switch again to output the signal from the main portion.

摘要： A telecommunications system (10) includes a first cross-connect switch (12) and a second cross-connect switch (14). The first cross-connect switch (12) includes a switching matrix that provides information from a matrix connection to a selector (28) of an output interface (18). The selector (28) places the information from the switching matrix onto one or both of a working channel (24) and a protection channel (26). The second cross-connect switch (14) receives the working channel (24) and the protection channel (26) at an input interface (20). The input interface (20) includes a selector (30) that checks a signal quality of the working channel (24) and the protection channel (26). When necessary, the selector (30) sends a request to the selector (28) to bridge the working channel (24) onto the protection channel (26). According to the signal quality, the selector (30) selects one of the working channel (24) and the protection channel (26) for transfer to a switching matrix (22) of the second cross-connect switch (14). The selector (30) avoids creating and deleting matrix connections in the switching matrix (22) in performing protection switches between the working channel (24) and the protection channel (26).

摘要： A telecommunications network (10) includes a plurality of nodes (12) interconnected in a bidirectional line switched ring configuration (18). The bidirectional line switched ring configuration (18) includes a working communication link (14) and a protection communication link (16) between each of the plurality of nodes (12). A particular node (12) within the telecommunications network (10) includes a first ring port interface (20) and a second ring port interface (22) each coupled to the working communication link (14) and the protection communication link (16). The first ring port interface (20) and the second ring port interface (22) are coupled by a cross connect matrix (24). The particular node (12) may have a protection channel access unit (30) to terminate control information carried over a protection communication link (16) of the bidirectional line switched ring configuration (18). In order to maintain transfer of control information over the bidirectional line switched ring configuration (18), a dedicated matrix connection (34) in the cross connect matrix provides a path to pass control information between the first ring port interface (20) and the second ring port interface (22).

摘要： A quality monitoring technique and detector is provided for checking the accuracy of modulation performed by a digital transmitter. The monitoring is performed without using a full receiver nor otherwise fully demodulating the signal to recover the baseband data. The modulated signal output by the transmitter is partially demodulated to a partial signal set on a single dimension of a two dimensional modulated signal matrix. The baseband signal is translated in accordance with a predetermined mapping format into the partial signal set on the single dimension for correlation against the partially demodulated signal. Failure to correlate indicates an error.
