Requirements.
3.2.1 Performance. The performance of the interface shall be
in
accordance  with  the  following  requirements.
3.2.1. Audio to FM radio. Connector J1-A3 shall be a +5
plus or minus 2 millivolt RMS sine wave when terminated into a 150
ohm plus or minus 1 percent resistor and referenced to J1-A4.
3.2.1.2 Audio to AM radio.  Connector J1-B4 shall be a +19.5,5
plus or minus 4 millivolt rms sine wave when terminated into a 50
ohm plus or minus 1 percent resistor and referenced to J1-A4.
3.2.1.3  Wireline  output. Connector J1-B6 shall be a +775
millivolt plus or minus 200 millivolt sine wave when terminated
into a 600 ohm plus or minus 1 percent resistor and referenced to
J1-A6.
3.2.1.4 Clipped frequency shift keying.
Connector P1-l shall
be a square wave with positive level greater than +3. 5 volts and
a negative level less than minus 3.5 volts when referenced to Pi-7.
3.2.1.5  Radio input. With an +8 millivolt to 2 volt rms sine
wave applied to J1-B5 with respect to J1-A4, Pi-l shall be as
specified in 3.2.1.4.
3.2.1.6  Wireline input.  With a +7.75 millivolt to .775 volt
rms sine wave applied to J1-B6 with respect to J1-A6, P1-1 shall
be  as  specified  3.2.1.4.
3.2. 1.7 Common connector contact continuity. The resistance
between the following respective connector contacts shall be less
than 7.5 ohms.
