Software brings messaging to home phone
designs
A novel software pacvkage based on the Texas Instruments C54CST provides a speedy route for OEMs to design fixed-MMS phones.
Spirit has developed a complete software package for developing fixed-MMS phones Using the software from Spirit, telecommunications companies can produce single-chip home phones capable of sending and receiving SMS and MMS messages from mobile networks

Home phones able to exchange SMS and MMS messages with mobile phones by connecting to SMS/MMS gateway server via regular phone lines are now considered to be the most innovative telecomms service emerging in the world.
Experts say fixed-MMS will soon become a common application in telecommunication networks.
The common based F-MMS standard will allow for interoperability between mobile and fixed MMS and will open the door for new services and exciting terminal equipment designs.

Client-side telephony chip simplifies integration
A new CST (client-side telephony) chip from Spirit is designed to solve the problems encountered when implementing speech compression, datacommunication and telephony functionality into new devices.
The market for fixed-MMS-enabled phones is now estimated to be several billion US dollars.
Spirit's solution is based on C54CST chip and is very simple to develop and integrate.
Modem, voice and telephony algorithms ROMed into C54CST chip with the MMS/SMS viewer application provide a solid base for developing fully functional fixed-line phone devices able to transmit and receive multimedia messages.
At the heart of the device, the C54CST is used for: uploading and downloading SMS and MMS messages (using modem software); audio playback (G.726 ADPCM); processing application code (JPEG decoder etc); and making regular phone calls (tone generation, echo cancellation).
All that OEMs need to successfully develop fixed-line phones featuring MMS is the TI C54CST chip with the MMS/SMS viewer software application, thereby reducing time to market.
Moreover, F-MMS technology can be supported not only by regular phones but by any device connected to the telephone line - fax machines, small PBXs, as well as gateways.
"F-MMS is not in competition with MMS on the mobile market", says Andrew Sviridenko, founding CEO of Spirit.
"A mobile phone is a purely personal device, and people keep them out of home most of the time".
"An MMS mobile phone needs a counterpart at home, to provide the best communication experience, and this will be the F-MMS terminal".
"Moreover, the cost of F-MMS communication over fixed telephone lines is structurally lower than the cost of communication over cellular links".
"Spirit now has two major deployments of fixed-MMS phones based on Spirit modem and telephony solutions, both of them in Europe".
"A range of companies from international F-MMS consortium are using Spirit technologies for their F-MMS phone products".
"Based on feedback from our customers, I have to say that both deployments have successfully passed internal and interoperability testing with SMS and MMS gateways".
