Radisys unveils MPH6 media processing card for LTE, HD video conferencing and more

Radisys Corporation, a provider of wireless infrastructure solutions, has launched a new high-capacity MPH6 media processing card for its MPX-12000 Broadband Media Resource Function (MRF).

The MPH6 is specifically designed to support the processing requirements for large deployments of real-time telecommunication services, including Voice over LTE (VoLTE), high definition (HD) video conferencing, and high-capacity multimedia transcoding services.

The demand for IP media processing is driven by the growth of VoLTE and real-time interactive video deployments, said Diane Myers, principal analyst, VoIP, UC and IMS, Infonetics Research.

“This trend will drive investments in IMS architecture with broadband multi-service media processing flexibility. The MPH6 is a great addition to the MPX-12000 to provide more processing power,” Myers added.


More than 250 mobile operators around the world have deployed LTE networks commercially and many are actively in the process of rolling out commercial VoLTE services and trials.

Infonetics Research has projected rapid growth in VoLTE subscribers over the next three years with more than 138 million VoLTE subscribers by 2016, up from 8 million at the end of 2013.

VoLTE enabled mobile phones and tablets that use HD audio (AMR-Wideband) codecs will require connectivity with GSM, CDMA or PSTN endpoints that use legacy codecs including AMR Narrowband (AMR-NB), EVRC or G.711.

As mobile operators transition subscribers to VoLTE, the underlying IMS services infrastructure will need scalable, economical and high-capacity transcoding capabilities to interconnect new VoLTE devices to legacy handsets and subscribers.

Radisys’ new MPH6 card, based on the latest multicore Digital Signal Processing (DSP) technology, delivers DSP power for processor intensive media stream manipulation. This delivers capacities in a small footprint, with a compelling price per port, the company claims.

The solution utilizes a broad range of HD audio and video codecs including H.264, VP8, and AMR-WB. MPH6 also leverages the MPX-12000 fault-resilient architecture to deliver reliable service by preserving active sessions for call continuity, customer satisfaction and revenue assurance.
