Page 10: Call Progress
536EPXX — Host Accelerated Modem 56K V.92 Chipset 7.2.7 Call Progress The modem monitors the detection of call-progress tones during call origination and reports them to the DTE. Call-progress tones include dial, busy, ringback, and answer. 7.2.8 Caller ID Caller ID is a service that allows the user to see the caller’s telephone number and name. Caller ID also provides information on call date and time. - Page 11 Host Accelerated Modem 56K V.92 Chipset — 536EPXX Table 14.
