A non-blocking crossconnect apparatus includes a primary bi-directional crossconnect device and a plurality of secondary bi-directional crossconnect devices. The primary crossconnect device has a plurality of pairs of bi-directional signal ports. A first one of each of the plurality of pairs of the bi-directional signal ports are arranged in a first set and a corresponding second one of each of the plurality of pairs of the bi-directional signal ports are arranged in a second set. Each secondary crossconnect device is associated with a respective one of the plurality of pairs of bi-directional signal ports and has a pair of secondary bi-directional signal ports and a pair of bi-directional signal leads. A first one of each pair of the bi-directional signal leads is operably connected to a respective one of the bi-directional signal ports in the first set and a second one of each pair of the bi-directional signal leads is operably connected to a respective one of the bi-directional signal ports in the second set. By utilizing symmetry and the bi-directional nature of communication lines, the present invention yields a rearrangeably non-blocking crossconnect apparatus as well as a strictly non-blocking crossconnect apparatus.

A process for ring bundling reduces the number of add/drop multiplexers required for a ring deployed in a telecommunications network. The input into the process is a list of all the time slots for a ring and the offices of the ring where each of the time slots adds or drops traffic. The process groups together time slots having many add/drops in common to maximize the number of offices where all the time slots pass through without adding or dropping traffic. OC-3 time slots are initially grouped in pairs, then in fours, then in eights, and finally in groups of sixteen to form one or more OC-48 optical signals transported in the ring.

A network architecture for configuring nodes and links into a plurality of interconnected hypercubes is presented. Each hypercube is interconnected with at least one other hypercube and operates substantially independently of the other hypercubes in the network. Each hypercube provides high levels of traffic routing diversity and restorative capability with less link capacity. Unique node labeling reduces inter-nodal communication, and traffic routing and recovery is accomplished with less complex algorithms.

An access node includes a switch that operates according to a first communication protocol. The access node is coupled by a plurality of feeder network channels to a second access node having a second switch operating according to a second communication protocol. A first distribution network port is coupled to the first switch and to a first distribution network channel bearing signals according to the first communication protocol. A second distribution network port is coupled to a second distribution network channel bearing signals according to the second communication protocol and to the second switch by one of the feeder network channels.

The present invention is a telecommunications network having a hierarchical architecture which reduces the amount of equipment and processing required to recover from network failures. In an exemplary embodiment, the nodes of the network are divided into high level nodes and low level nodes. High granularity traffic is collected, routed and manipulated at high level nodes, but generally passes through low level nodes, which generally lack the capability for routing and manipulating such high granularity traffic. Equipment savings results from low level nodes lacking the capability to manipulate traffic other than traffic relevant to those nodes or nearby nodes. Each high level node pair is connected by at least three node disjoint paths of low level nodes and links. Less protection capacity is needed, as each node disjoint path is expected to handle only a portion of rerouted traffic in the event of a network equipment failure. Recovery is decentralized, and is thus faster, requires less equipment, and is less susceptible to the failure of a centralized controller than with networks using centralized recovery processing.

The present invention provides a device and method for achieving protection in a free-space micromachined optical switching fabric. The present invention provides two protection schemes for mirror failures, which utilize either existing switching mirrors or additional integrated mirrors without extra fabrication effort or performance-degradation of the switch fabric. A switch fabric includes a plurality of micromachined free-rotating mirrors arranged in a rectilinear matrix configuration. The mirrors are reflective on both front and back sides. According to one embodiment of the present invention, upon the detection of a failed mirror associated with a transmission between an input and an output, a transmission path is determined that includes a backside of a pivot mirror. A transmission path is then established between the input and the output that utilizes the backside of the pivot mirror.
