Abstract:
1. A data relaying device that receives data over a wired network and sends the data over a wireless network, comprising: a receiver that receives from the wired network data in packets encoded under a PCM coding scheme, wherein the receiver examines the received data to detect and distinguish any undecodable packet from decodable packets and outputs an undecodable signal when it finds an undecodable packet; a PCM decoder that decodes data in the decodable packets under the PCM coding scheme; an AMR (adaptive Multi-Rate) encoder that encodes under an AMR coding scheme the decoded data from the PCM decoder and outputs encoded data in frames in which the AMR encoder, when it receives the undecodable signal from the receiver, stores an indicia of undecodable data in a frame corresponding to the undecodable packet indicated by the outputted undecodable signal from the receiver identified by the undecodable signal outputted from the receiver; and a transmitter that transmits to the wireless network the frames of data from the AMR encoder.
