Critical Decision – Operating System
• Incorporated in October 2001
• Moved into current building December 2001
• Had to decide on an operating system for the MX1200
by February 2002
30
Operating System – Requirements driven
• MX1200
– Integrates voice, video, data and fax
• Requires RTOS
–
–
–
–
–
Uses 4 IBM 440GP processors
Functions as a firewall
Uses PPP for WAN links
Routing protocol support
SIP and VoiceXML support
• Wanted to be able to quickly add new functions and
protocol support

Operating System – Experience
• Multiple developers familiar with VxWorks and Nucleus
• Few developers with experience using Linux
?
33
Operating System – Decision Made
• Windows 2000
– Never considered due to product reliability requirement
• VxWorks
– People from Wind River were very difficult to work with
– Pricing structure was highly unpalatable to us
• Nucleus
– Considered too light to power our product
• Real Time Linux
– Found Monta Vista to be good to work with
– Pricing structure was acceptable
34
Linux – Working on IBM 440GP
• May 2002 and still did not have proper drivers
for the IBM 440GP
– Initially there was no Linux support for this
processor
– Monta Vista developers checked code into the open
source tree
– We spent a lot of time reviewing, commenting and
improving
• June 2002
– Linux working on IBM 440GP at Zultys
• September 2002
– Monta Vista formally announced support for the IBM
440GP
35
Linux – Open source applications
• Quality of open source applications
– In many cases found to be greater than high dollar
solutions proposed by software companies
• Applicability
– Some open source implementations not optimised
for embedded systems
– Required a lot of time and effort to improve
performance
36
ZIP 4x4 – Powerful IP Phone
• Processor
– IBM 405 GPr
– Scalable to handle the current and proposed
applications
• AEC for full duplex speakerphone
• 5 way conference mixing
• Speech compression
• Operating system
– Decided to leverage our Linux experience
• Improved our time to market
37
ZIP 4x4 – Benefits of Linux
• Open, stable and reliable
• Useful applications
– DHCP
• Obtain IP address and TFTP server
information
– TFTP
• Contact TFTP server for software and
configuration updates
– NTP
• Establish and maintain time synchronization
• Many additional functions planned
– Easy to accomplish with Linux

“The Zultys MX1200 is based on IBM’s
PowerPC 440GP system on chip processor,
which was created for mid- to high-end
devices that require a rich mix of embedded
peripherals. Utilizing the integrated Ethernet
on the 440GP to network all four processors
together, Zultys was able to greatly reduce
their development time. We believe IBM’s
PowerPC processors will provide Zultys with
a consistent, scalable development platform
for their future products.”
