发明名称 HYDRAULIC FAN DRIVE SYSTEM EMPLOYING BINARY CONTROL STRATEGY
摘要 A method for communicating information to a caller on a telephone network is herein proposed. The method includes the steps of (a) generating a signal suitable for producing an audible dial tone, (b) transmitting the signal to the receiver of a telephone set, when the caller initially takes the receiver off-hook, to thereby produce the audible dial tone, and (c) superimposing an audible information message over the audible dial tone while the audible dial tone is produced. The audible information message may, for example, be a branding-type message that identifies a provider of local telephone service to a caller. The audible information message may be superimposed over the audible dial tone in a whisper-like or low-decibel manner to avoid interfering with modems that operate on a "wait for dial tone" (WFDT) basis.
