Abstract: A system (100) for processing simplex and multiplexed voice packets transmitted over a network is disclosed. The system (100) may include a processor (102) and a compare section (104). A compare section (104) may include simplex entries (110-0) and multiplex entries (110-1). The compare section (104) can compare voice packet information with simplex entries (110-0) and multiplex entries (110-1) simultaneously to correlate voice packet data with a given voice channel.

Abstract: A system for transmitting real-time data between an asynchronous network (104) and a synchronous network (106) is disclosed. A method (100) may include an ingress path (102) for transmitting data from an asynchronous system (104) to a synchronous system (106), and an egress path (108) for transmitting data from a synchronous system (106) to an asynchronous system (104). An ingress path (102) may include a packet receiver (110) and write to synchronous system (112) steps. An egress path (108) may include read from synchronous system (114), packetizer (116), and packet transmitter (118) steps.

Abstract: A system (100) is disclosed that may transfer voice data from multiple channels between an asynchronous data network (102) and a synchronous data network (104). A system (100) may include an egress block and associated structures (200) and/or an ingress block and associated structures (900). An egress block (200) may read voice channel data from a local buffer (206) and write such data to a voice packet buffer memory (VPBM) (204). At least a portion of a VPBM write address may be generated from a time stamp value. An ingress block (900) may read voice channel data from a jitter buffer (918) and write such data to a local buffer (906). At least a portion of a jitter buffer read address may be generated from a time stamp value.

Abstract: A system (100) for processing simplex and multiplexed voice packets transmitted over a network is disclosed. The system (100) may include a processor (102) and a compare section (104). A compare section (104) may include simplex identification (ID) entries (110–0) and multiplex ID entries (110-1). The compare section (104) can compare voice packet information with simplex ID entries (110-0) and multiplex ID entries (110-1) to correlate voice packet data with a give voice channel.

Abstract: A system (100) for receiving data from an asynchronous network and transmitting such data onto a synchronous network includes a voice packet buffer memory system (108) with a jitter buffer (118) having groups of entries storing data for voice channels and jitter buffer valid bit (JBVB) memory (120) for status of a particular entry for multiple jitter buffer groups. Writing or reading data from a jitter buffer entry sets a corresponding JBVB memory bit to a valid or invalid state respectively. Jitter buffer data may be read with a corresponding state memory bit. If a corresponding JBVB memory bit is valid, data from a jitter buffer (118) may be provided as an output. If a corresponding JBVB memory bit is invalid, a loss recovery algorithm may compensate for such invalid jitter buffer data.
