The present invention relates to a communication system and method and, more particularly, to a fault tolerant network element for providing fault tolerant call connections in the event of a failure of, for example, a Gatekeeper or other part of a network. Calls set up across a network consume large amounts of resources both throughout the network and at the devices which form the end points of the network. Therefore, even though a call connection may be supported, in the event of the failure of a network element, it is often the case that there is an ungraceful failure or use of resources throughout the network. Accordingly, an aspect of the present invention provides a method for preserving a connection context at a first layer of a communication protocol; the communication protocol comprising a second, higher, signalling layer in which, in response to a switch-over from an active host to a standby host in the event of failure of the former, the connection is terminated in response to receipt of a signalling layer signal other than a disconnect or terminate signal.

In an ultrasound imaging system that applies a beamformer to received ultrasound signal samples to form one or more beams represented by arrays of beamformed samples, a method and an apparatus compress each array of beamformed samples independently of the other arrays to form compressed beams. A plurality of analog to digital converters sample multiple analog ultrasound signals produced by a transducer array to provide multiple streams of ultrasound signal samples to the beamformer. The compressed beams are transferred via a digital interface to a signal processor. At the signal processor, the compressed beams are decompressed to form decompressed beams. The signal processor further processes the decompressed beams for diagnostic imaging, such as for B-mode and Doppler imaging, and scan conversion to prepare the resulting ultrasound image for display. This abstract does not limit the scope of the invention as described in the claims.
