The TPM-32 Digit Grabber
dialed digit meter monitors and analyzes DTMF and dial pulse
signaling through any telephone or wireless communications
system. It is a high-impedance (100K ohms) instrument that
bridges the line without loading. Tones are heard through the
monitor speaker as they are displayed.
In the display mode, digit strings of up to 32
characters are captured and frozen on the large,
alphanumeric screen. When more than 32 digits
appear the first digits drop off to allow the
latest characters to be shown. In the analysis
mode, inter digit timing and tone burst timing
are displayed for tone dialing and make/break
ratio and pulses per second are displayed for
pulse dialing. Digit Grabber operates on a
standard 9V battery.

The basic model is a valuable test tool for technicians
working with store and forward dialers; security systems; keypad
maintenance on standard, mobile or cellular phones; and other
CPE items using tone digits for programming or signaling.
The MF model is suited to carrier troubleshooting of
MF signaling, especially for equipment used in Feature Group B
or D service and does not have an analysis mode.
