interfaces to the packet network; is designed to provide a

UTOPIA level-2 interface and H.100 TDM interface; and is

designed to run essential application-specific protocols

required by the target application.

As the communications industry migrates from circuit-switched to packet-centric

infrastructure, equipment manufacturers require systems solutions that include

comprehensive design tools, signal processing, the ability to interface with both

packet- and circuit-switched networks, control and signaling functions, and

software support.

The DSP subsystem is designed to run essential signal

processing functions for voice, fax and modem data

applications. At the heart of the DSP subsystem are six

MSC8101 DSPs in a PTMC form factor. Typical functions

include voice compression, DTMF detection, voice activity

detection, echo cancellation and silence suppression, as

well as modem and fax data modulation and

demodulation. The DSP subsystem interfaces to the

MPC8260 baseboard via the MSC8101’s 60x bus. The

POTS subsystem connects to the DSP subsystem, and it

offers four narrow-band T1/E1 TDM ports. The POTS

subsystem is also designed to support four analog

POTS ports for direct interfaces to standard analog

voice terminals, and it provides a TDM stream for the

DSP array.

The first in a series of integrated, yet flexible, packet telephony system solutions from

Motorola, Smart Packet Telephony 8101 is a hardware reference design for medium-size

media gateway equipment that can handle voice, fax or modem data services.

The reference platform and development kit are ultimately designed to give

manufacturers of remote access servers (RAS) and IP-PBXs that are based on MSC8100

DSPs a significant time-to-market advantage. At the front end of the design process,

system architects may use this scalable evaluation platform to assess the capabilities

of the StarCore^®architecture-based MSC8100 DSPs and establish suitability for their

end product. Since it is a comprehensive hardware reference design, it is also designed

to facilitate rapid system development. Multiple third parties supply media gateway and

remote access server software to complete the packet telephony solution.

The development platform includes support for voice compression and echo cancellation,

essential for voice-over-packet systems. Smart Packet Telephony 8101 consists of three

main subsystems. The MPC8260 baseboard is designed to support Fast Ethernet
