for transporting multiple media types between circuitswitched and packet-based networks. The M80303 is ideally suited for enterprise and carrier infrastructure solutions serving the converging voice and data networks.
Mindspeed’s M80303 addresses new requirements such as Fax over IP (T.38), and modem pass-through while maintaining support of traditional PSTN data/fax termination needs. Additionally, the M80303 supports a rich feature set of Voice over Internet Protocol (VoIP) encapsulations and protocols.
The M80303 combines powerful DSP cores with a Applications include small and midrange voice and data
programmable packet-processing ARM™ controller. This processor is offered as a complete software solution, running Mindspeed’s extensive suite of field-proven
terminating routers, IP PBXs, WAN access devices, low density remote access concentrators (RAC), voice gateways, call agents, and various other products benefiting
data and fax modulations, voice echo cancellers and general telecommunications protocols, providing complete
from a complete voice and data access system solution.
