A digital signal processing (DSP) chip for Internet equipment, that nearly triples the number of voice and data calls that can be processed by service providers, has been released by Lucent Technologies' Microelectronics Group.
The DSP 1695 chip, which integrates four separate DSP core subsystems, is targeted for use in remote access concentrators and servers, central office switching systems and other network access equipment.
Lucent claims its chip can process 16 simultaneous voice and data calls - compared to competing chips that can process a maximum of six calls. It is hoped that the chip will substantially reduce equipment and maintenance costs.
The chip can also support multiple services, such as 56Kbps modems, voice and fax over IP, 56Kbps and 64Kbps ISDN, and wireless data transmission.
"Average selling prices of remote access concentrators declined 30 per cent between 1997 and 1998, largely due to new offerings by silicon providers," said Shannon Pleasant, senior analyst with Cahners In-Stat Group. "This Lucent chip should enable even greater price reductions."
