M-985-01
Precise Call Progress and
Special Information Tone Generator
Description
The M-985-01 is an integrated circuit precise tone
detector for call progress and special information
tones (SIT), as defined by CCITT.
The use of integrated circuit techniques allows the
M-985-01 to pack the eight filters for call progress
detection into a single 22-pin DIP or a 20-pin SOIC. A
3.58 MHz crystal-controlled time base guarantees
accuracy and repeatability.
The M-985-01 combines the call progress detection of
the M-982-02 and the SIT detection of the M-984-02.
It has an operating voltage range down to 3V. It has
low power consumption under normal operating con-
ditions. A power down (PD) feature is provided to fur-
ther reduce power consumption when inactive.

Call Progress Tone Detection
Call progress tones are audible tones sent from switch-
ing systems to calling parties to show the status of calls.
Calling parties can identify the success of a call placed
by what is heard after dialing. The type of tone used and
its timing vary from system to system, and though
intended for human ears these signals can provide
valuable information for automated calling systems.
The M-985-01 contains five signal detectors sensitive to
the frequencies often used for these progress tones.
Electronic equipment monitoring the OUTn outputs of
the M-985-01 can determine the nature of signals pres-
ent by measuring their duty cycle. See Mechanical
Dimensions for a diagram of a circuit that could be used
to permit a microcomputer to directly monitor tones on
the telephone line. Much of the character of the
progress tones is in their duty cycle or cadence (some-
times referred to as interruption rate). This information,
coupled with level and frequency indication from the M-
985-01, can be used to decide what progress tones
have been encountered.
