The complex mathematical operations in modems mainly rely on DSP or ASICs composed of DSP cores to complete. In portable computers, when particular attention is paid to the size, weight, and power consumption of modems, the requirements for DSP come higher. The speed of modems continues to increase with the increase of DSP speed, reaching 56kbps by 1997.
(6) Integrated Services Digital Network (ISDN)
ISDN significantly reduces costs while greatly improving data transmission rates. This has led to the development of new businesses that require high-speed data transmission rates and real-time information processing, such as interactive publishing, video conferencing, remote healthcare, remote education, etc.
Take video conferencing as an example. Due to the need for a wide bandwidth to transmit video images and sound, traditional video conferencing requires specialized rental of expensive broadband channels. The H.320 encoding implemented by the latest DSP based video conferencing system is compatible with international video conferencing and ISDN video telephony. That is to say, it is possible to access the 6 basic rate interfaces (i.e. 6 × Run video conferencing on 64kbps.
The dual mode modem implemented by DSP can operate in both analog mode and digital format on analog channels, as the ISDN system is digital.
