modem on hold

A feature of V.92 modems that allows users to connect to the Internet and switch to an incoming voice call when a call waiting signal is detected. When the voice call is terminated, the line is switched back to the Internet. There is a timeout period in which the user must end the voice call, otherwise the Internet connection is dropped.

If the user's modem is V.92, but the ISP supports only V.90 modems, this feature disconnects the Internet call and answers the voice call. Prior to V.92, when the user was online, a call waiting signal often dropped the Internet and voice connection. See V.92.


The last analog modem standard. Superseding V.90 and introduced in 2000, V.92 boosted the upstream data rate from 33.6 to 48 Kbps (downstream remained the same at 56 Kbps). V.92 reduced handshaking (connecting time) by remembering the previous settings negotiated when dialing the same telephone number. V.92 also supports call waiting by allowing the Internet data session to be put on hold while a voice call is taken. See modem, modem on hold and V.90.
