Abstract: An apparatus, method, and computer readable medium thereof for simultaneously establishing links with a plurality of nodes in a wireless network are provided. A processing module determines whether a mesh network configuration message of the apparatus has space to packet an information element and determines whether to transmit a Neighbor Link Establishment information element to one of the nodes. If the mesh network configuration message has space to packet an information element and the Neighbor Link Establishment information element needs to be transmitted to one of the nodes, the Neighbor Link Establishment information element will be packeted into the mesh network configuration message. Finally, a transmission module transmits the mesh network configuration message to the nodes in order to solve the problem of increasing time during link establishment and avoid deadlock among the nodes when the apparatus of the prior art establishes links with the nodes simultaneously.

Abstract: A serial communication system includes a master processor and a slave processor. A CS signal for requesting a serial communication is output from the master processor, and an OK_INV signal for responding to the CS signal is output from the slave processor. When a CS signal is an active state, the master processor executes a serial communications of a preset number of bits every time that a level of the OK_INV signal is reversed. The slave processor inverts a level of an OK_INV signal in response to the CS signal shifting to the active state. The slave processor changes the level of the OK_INV signal every time that a serial communication of a preset number of bits is completed.

Abstract: An apparatus and method for centrally selecting a control network from redundant control networks is described. In one embodiment of the invention, a network element includes a first control network and a second control network. Each line card implements a bonding interface to bond a first port coupled with the first control network and a second port coupled with the second control network. On each line card, the first and second ports receive a control network selection message from the first and second control networks respectively. A link layer driver on each line card interprets those selection messages and determines which control network is active and reports that control network as up to the bonding interface and reports the other control network as down to the bonding interface. The bonding interface selects the control network reported as up and application software uses that control network.

Abstract: A processing device and method for processing packets of encoded real-time data to perform a gradual fade-out and fade-in of a signal. Upon detecting the beginning of a packet loss period, a last correctly received packet is repeated with gradually increased attenuation to slowly fade out, for example, an audio signal. At the end of the packet loss period, the device slowly fades in the signal by attenuating the first or a number of packets received following the loss period. The method may be performed with low complexity by decrementing segment numbers of samples of data packets such as in a lookup operation.
