Abstract: An apparatus and method determine byte gain and loss adjustments that compensate for frequency differences between ingress and egress data rate signals in a SONET/SDH NE. The count of ingress data rate signal pulses at the time that data is requested by a switch fabric is compared to the count of egress data rate signal pulses at the time the requested data is passed through the switch fabric. If a delta phase equal to the difference in counts less a reference phase, is continuously greater than a positive value threshold for at least a time threshold period, then a byte gain adjustment is determined. On the other hand, if the delta phase is continuously less than a negative value threshold for at least the time threshold period, then a byte loss adjustment is determined.

Abstract: A field reconfigurable muxponder for use in an optical transport system. The muxponder includes one or more tributary cards, where each tributary card is adapted to receive an optical data signal and conditions the optical data signal into an intermediate data signal constituted in accordance with a tributary interface format. In this way, the muxponder is able to aggregate optical data signals having different protocols and/or different data rates. The muxponder further includes a chassis that is adapted to receive a predefined number of tributary cards and outputs an optical system signal independently from the availability of the optical data signals from the tributary cards. The tributary cards and the chassis integrally form one line card.

Abstract: Apparatus for transmitting a data stream between cards connected by a midplane breaks the data stream into a plurality of channels. The apparatus comprises a serializer for each channel. Serialized data is transmitted across the midplane to a deserializer at the destination. Sequential cells are sent in different channels. Cell ordering is preserved by staggering the start of cell transmission in the channels. The invention permits data to be transmitted across a mid plane using a reduced number of data lines. The data stream on each card may be carried in a wide bus at a relatively low clock rate. Apparatus according to the invention may be used to transmit an OC-192 data stream across a pin-limited interface.

Abstract: An SDH transmission unit which processes various classes of digital bitstreams regardless of their levels of the SDH multiplexing hierarchy, harmonizing the signal formats handled in its integral cross-connect facilities. High-order group transmission units are installed in their dedicated high-order group slots on a mounting rack, and through the wiring on a backplane, they are connected to high-order group ports of a cross-connect unit installed in the same rack. Similarly, low-order group transmission units are installed in dedicated low-order group slots on the mounting rack, and connected to low-order group ports of the cross-connect unit through the backplane. Both high-order and low-order group transmission units are designed to send and receive multiplexed signals at a predetermined level of the SDH multiplexing hierarchy. Because of this harmonized signal format, the high-order and low-order group transmission units seamlessly interface with the cross-connect unit, no matter what level of multiplexed signals they process in their internal activities.

Abstract: In a cross-connect multiplexer (CCM2), a plurality of interface units, among others those (AE1) for STM-1 signals of the synchronous digital hierarchy (SDH), are connected to a space-division switching network (RKF). The section overheads of these synchronous transport modules (STM-1) overall are partly received and analyzed and partly multiplexed and sent out in a section overhead server (SOHS) with the assistance of a network control unit (NCU). This process is simplified by STM-1 signals being converted into a plurality of D39 signals, known per se, of a bit rate of 38,912 Mbit/s, and conversely, only bytes necessary for transmission of the section overheads being inserted into only one of the sixteen frame columns of a D39 signal belonging to the STM-1 signal via the space-division switching network (RKF). It is only these special columns of in each case sixteen STM-1 signals which are combined to form a separate D39 signal which is received or transmitted by the section overhead server (SOHS). Such cross-connect multiplexers (CCM2) are used in network nodes of digital networks.
