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 with each J1 pulse indicating the start of an STS-1. 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. Shown is STS-1 number 1 being added to the Add bus.
