vDot modems

Voice Dialing over Tones (vDot™)

A PC equipped with a vDot enabled modem has capability to provide high accuracy, low cost voice enabled dialing throughout a home on existing telephones and wiring.

vDot enabling technology is included in new and upgradeable standard modems via the extended 'AT' control command AT+VLS=20. Modems with support for the command AT+VLS=20 provide ability for a PC processor to acquire speech audio on a telephone line during the pre-dialing period indicated by a presence of Dialtone.

Compatible software on a PC is expected to execute the DTE to DCE command below to engage vDot mode on a modem:

Modem products with vDot technology are expected to be available in U.S. domestic retail in Q2 2000. A partial list follows of companies that have implemented vDot, or have existing products that are memory upgradeable to vDot technology
