A telecommunications gateway allows packets to be sent over a TDM system and allows TDM traffic to be sent over a packet switched network. The gateway is a universal port that includes a plurality of Digital Signal Processors (DSPs) that are controlled by software. The controlling software determines what single function the DSP will perform over multiple channels. Each DSP handles multiple channels, however, each DSP is restricted such that all of its multiple channels are permitted to handle the telecommunications traffic according to one signaling protocol.

Dynamic DSP allocation for universal access to a packet network

In a system in which user equipment is connected to a packet network and a speech recognition application server is also connected to the packet network for performing speech recognition on speech data from the user equipment, a speech recognition system selectively performs feature extraction at a user end before transmitting speech data to be recognized. The feature extraction is performed only for speech which is to be recognized.
