Simulation Test, Tape #201 from PUB 56201
Better than: < 1/2500 calls Test: 10 digit calls nominal
frequency @ -23 dBmO ON/OFF = 50 ms/50ms KP
duration 100 ms 60 Hz signal @ 81 dBrnc0 (-9dBm)
or 180 Hz signal @ 68 dBrnco (-22dBm) all digits
Must tolerate @A-B and @B-A modulation products
with a power sum 28 dB below each frequency
component level of the signals.
The receiver must not respond to signals prior to KP.
Remain unlocked until ST, STP, ST2P, or ST3P is
received.
After the initial KP, subsequent KP's are ignored while
in unlocked mode.
If more than two valid frequencies are detected, no
digit is reported to the CPU.
