Access Processor Claimed As Highest Density VoIP Chipset

Claimed as the industry’s highest density voice over IP (VoIP) chipset for applications such as access, trunking and 3G wireless gateways, the MTN3600 Access Processor provides a scalable solution for IP-based enterprise and carrier networks. Based on the company’s first generation UniPorte technology, the two-chip set consists of a Media Processor System-on-a-Chip (MPSoC) and a Portal Processor System-on-a-Chip (PPSoC). The MPSoC performs media processing functions and provides a standard interface to 8.192 MHz TDM streams. The PPSoC performs packetization, aggregation and host interface functions. A single MTN3600 PPSoC can support up to eight MPSoCs in a bank configu-ration reaching OC-3 port densities for high-density applications. The Access Processor provides this high density by employing the company’s DynaScheduler. This proprietary technology dynamically allocates processor resources according to the needs of a sub-task running on a particular port, rather than a fixed amount of resources, regardless of the sub-task requirements. According to the company, DynaScheduler results in a more efficient use of processing resources and enables higher port densities than previously possible for hybrid vocoders. For example, configured for a typical VoIP application requiring G.711 and G.729A or G.723.1, a single MTN3600 MPSoC can dynamically support over 200 ports. The MTN3600 Access Processor will be sampling in Q3, 2002, with production availability slated for Q4, 2002. For more information, contact MAPLETREE NETWORKS INC., Norwood, MA. (781) 751-2400.
