Methods and systems according to one or more embodiments establish communication across separate IP domains that are on the same layer 2 bridged domain. In an embodiment, a method includes receiving a configuration of a first IP address of a first node on a first side of a switch and a second IP address of a second node on a second side of the switch, wherein the first and second IP addresses are of different domains and are to be translated in each direction with respect to the switch, wherein the switch further comprises an integrated block adapted to do translation at line rate. Based on the configuration, the method also includes modifying, by the switch, packets of an applicable protocol in each direction so that the first and second IP addresses are changed for each domain such that either side of the switch acts as if an opposite side is on the same domain so that layer 2 communication is established.

In network systems for transporting GFP-encapsulated FICON frames across a SONET/SDH transport network between FICON ports, the transport interfaces for the FICON ports operate to drop duplicate and out-of-order frames transported across the SONET/SDH network. The transmitting transport interface inserts a sequence number incremented with each FICON frame into said one or more transport frames, whereby the sequence number is used as an index for determining duplicate and out-of-order frames after transport over said SONET/SDH network. The receiving transport interface compares sequence numbers with each FICON frame to determine duplicate and out-of-order FICON frames, drops the duplicate and out-of-order FICON frames; and sends the balance of the compared FICON frames to the receiving FICON port.

Methods and apparatus for automatically detecting the frame format of a data signal and automatically provisioning a port based on the detected frame format are disclosed. According to one aspect of the present invention, a framing format detection mechanism that is suitable for use in a network within which a data signal is arranged to be transmitted includes a first device and a second device. The first device is arranged to be a part of a line card and in communication with a signal receiving port on the line card. The first device is also arranged to automatically determine a frame format associated with the data signal. The second device is arranged to display the frame format associated with the data signal substantially in real-time. In one embodiment, the first device is further arranged to automatically provision the port.

A method and system for flow control of GFP-encapsulated client data frames over SONET/SDH transport networks is described. Transport interfaces, in the form of port cards, have FIFO buffers for receiving the GFP frames. In acknowledgment of the received frames, a transmitting transport interface receives an acknowledgement in form of a returned frame sequence number tag along with the available capacity in bytes of the buffer of the receiving transport interface. With a continuous update of buffer capacity and tracking the number of bytes in transit to the receiving transport interface, the transmitting transport interface maximizes the utilization of the channel through the SONET/SDH transport network, even with dropped frames or dropped acknowledgment tags.

Integrated circuit bus integrity may be verified without specialized test equipment. In a diagnostic mode, the integrated circuit may output a series of predetermined activation patterns onto the data bus to verify integrity of the data bus. Further bus verification may be provided by an address capture mode where address bus contents are reflected onto the data bus. A microprocessor may control diagnostic mode operation.

Methods and apparatus for identifying a frame format associated with a DS3 data signal are disclosed. According to one aspect of the present invention, a method for detecting a frame format of a signal which has a plurality of frames includes receiving a first frame and determining when a parity associated with the first frame and a first bit associated with the first frame indicate that a first counter is to be incremented. The first counter is incremented when it is determined that the first counter is to be incremented. The method also includes determining when the signal is of a first format through a comparison of the first counter with a first threshold.

A therapeutic hand device comprising a first thumb-sleeve for receiving therein the thumb of a hand, a second index-finger sleeve for receiving therein the index finger of the hand, and a third middle-finger sleeve for receiving therein the middle finger of the hand. The first thumb-sleeve is connected to said second sleeve and is also connected to the third sleeve by adjustable straps. An open space is defined interiorly of, and delimited by, the first, second and third sleeves, whereby when the device is worn on a hand, an object may be inserted into the open space between the first, second and third sleeves, with the adjustable straps being used to firmly hold the thumb and fingers in a pincer hold against the object, whereby the object may be held and manipulated with support and assistance by the device.

Digit-supporting therapeutic device for the hand

A therapeutic hand device comprising a wrist-support section and a separate fingers-support section. The fingers-support section receives the index-finger and the middle finger, and is removably secured to the wrist-support section via a plurality of adjustable 'VELCRO' straps. An open space is defined interiorly of, and delimited by, the fingers-support section and a portion of the wrist-support section whereby when the device is worn on a hand, an object may be inserted into the open space between the fingers-section and the thumb of the hand, with the adjustable straps being used to firmly hold the thumb and fingers in a pincer hold against an object, whereby the object may be held and manipulated with support and assistance by the device.

A method and system for emulating an Fibre Channel link over a SONET transport path by which Fibre Channel data is transported across the SONET/SDH transport path. To provide link integrity, techniques to handle link failures from a Fibre Channel element to its associated Fibre Channel port, or of the SONET/SDH network linking Fibre Channel ports include transmitting error condition codes over the SONET/SDH transport path overhead to a remote Fibre Channel transport interface so that the Fibre Channel link from the remote Fibre Channel transport interface to the associated remote Fibre Channel port is disabled. Timing the length of failures and return of operation of the failed links is used to handle transient conditions and to avoid link bouncing.

A method and apparatus for simultaneously applying and blending pigmented cosmetics is one step, wherein pressurized air is released from a container, is divided into one or more spray channels, and exits together with pigmented cosmetics through a directional shield onto an individual's skin. The pigmented cosmetics are mixed with the pressurized air by various means. In a preferred embodiment of the apparatus, a part or the entire directional shield can be removed, enabling changes in the size and shape of the area of skin where the pigmented cosmetics are deposited. For some embodiments of the apparatus, the colors and types of cosmetics used can be varied by switching interchangeable cartridges or canisters of cosmetics.
