The relationship between J1 and the SPE signals is shown for illustration purposes
only, and will be a function of the pointer offset. For the STS-3 format, there will be
three J1 pulses which indicate the start of each of the STS-1 SPEs. The C1 pulse
is shown dotted because the C1 pulse may be provided on the DC1 signal lead. If
the DC1 signal lead is not used, it must be grounded.
