Providing interoperability on a voice communication network by detecting incompatible bit packing payload formats of ADPCM encoded voice data signals in an encoder/decoder. A mismatch of bit packing formats between little endian format and big endian format is determined by detecting the occurrence of ADPCM code words of interest in the decoded voice data stream out of the encoder/decoder. The invention may be applied to an ITU G.726 encoder/decoder.

Interoperability of ADPCM encoded voice communications

A system and method are provided for improving the throughput of wireless networks, such as IEEE 802.11 networks. Individual devices in the network determine the level of activity on the network. In the event that the network is active, the devices increase throughput by skipping the pending packet transmission and appending its data payload to a future packet transmission. By encoding multiple payloads in a single packet transmission, packet overhead is reduced and MAC layer delays are eliminated. The data payloads are subsequently split back into individual packets for transmission over the wired portion of the network.

Increasing the throughput of voice over internet protocol data on wireless local area networks

A system to enable TTY communication between a legacy TTY phone and an IP phone over a packet network using a TTY relay protocol established between the IP phone and a media gateway at a central office of the PSTN. The system may also use a voice over Internet Protocol gateway to connect a personal computer to the packet network instead of an IP phone to accomplish TTY communication between software on the computer and a legacy TTY phone.
