The protector should not clip or limit the voltages that occur in normal system operation. If the maximum system voltages are not known, then
designers often used the voltages for the FCC Part 68 “B” ringer. The “B” ringer has a d.c. voltage of 56.5 V and a maximum a.c. ring voltage
of 150 V rms. The resultant waveform is shown in Figure 11. The maximum voltage is -269 V, but, because of possible wiring reversals, the
protector should have a working voltage of ±269 V minimum. The TISP4350MM protector meets this requirement with a working voltage,
V
ringing voltage.
The ADSL signal can be as high as ±15 V and this adds to the POTS signal making a peak value of -284 V. This increased signal value of
-284 V would be clipped by the TISP4350MM, which only allows for a -275 V signal. The TISP4360MM has been specified to overcome this
problem by having a higher working voltage of ±290 V. Figure 13 shows the TISP4360MM voltages relative to the -284 V peak ADSL plus
POTS ringing voltage. The ±15 V ADSL signal is shown as a gray band in Figure 13.
