Advantages of Using SurfWare-Media for Transcoding GSM-AMR-NB and other Codecs
- Voice, Video and Fax/Modem processing on the
same DSP
Other solutions separate Voice & Video processing
(different DSPs/host) causing system to be unbalanced.
- Direct DSP—network interface for lowest
possible delay
Solutions with DSPs that do not have direct IP network
interface suffer from unnecessary delay and bottlenecks.
- Open Platform
Vendors are able to add SW modules to the DSP code,
in order to create a competitive advantage, without
the need to recompile the DSP or host interface code
Closed system solutions don’t allow vendors
to add value to the media processing sub-system. External
memory is a must for providing an open platform.
- Support for various applications with the
same HW/SW
Possible ONLY when Voice & Video run on the same
DSP.
- Streaming diagnostics for quick resolutions
of issues
Solutions without external memory cannot include diagnostics
in the release version.

A Complete and Open Solution
SurfWare-Media™ offers an unprecedented
range of Voice, Video, Fax and Modem conversion engines.
These are offered in various hardware and software
integration levels, ranging from software algorithms
to DSP-farm resource boards. Surf’s Open Framework
enables customers to integrate their own technology
easily into Surf's offering, resulting in significantly
shortened time-to-market and reduced development costs.
SurfWare-Media supports ITU-T V.18: Termination of TTY/TDD
end user equipment, including support for different
terminals defined by the V.18 standard. In these cases,
SurfWare-Media acts as a building block for the Telecommunications
Relay Services (TRS).

SurfWare-Media for Media Gateway Developers
Developers of Media Gateways are facing
constant pressure on their pricing criteria. They
are also required to improve their offer continuously
for the support of legacy and new media types. SurfWare-Media,
a field-hardened Universal Port solution, optimized
for densities of E1/T1 on-a-chip, offers support for
an extensive range of Voice, Video, Fax and Modem
features. Additionally, it enables customization by
facilitating the integration of Media Gateway technologies
into Surf’s solution by developers. |
SurfWare-Media for Messaging System Developers
Developers of Voice and Video Messaging,
Unified Communications, IVR and Attendance systems
need to efficiently and reliably convert data that
arrives from various networks and in diverse formats
into storable file formats and vice versa. These store-and-forward
systems are particularly sensitive to communication
bottlenecks. Relying on available temporary storage
of up to 24MB per DSP (when using the recommended
hardware configuration), SurfWare-Media provides efficient
Host-DSP communications for continuously smooth operation. |
SurfWare-Media for RAS System Developers
In the market of RAS systems, manufacturers
are continuously struggling to offer new and unique
solutions. With SurfWare-Media, RAS system manufacturers can
lower their solution's cost per-port, get higher density
per chip (up to 32 ports) and offer new features,
such as same-chip support for VoIP and RAS calls.
These enable them to increase their competitiveness
in a tough market. |
