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 STM-1 format, there will be one J1 pulse
which indicates the start of the VC-4 that carries the three TUG-3s. 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 TUG-3 A being added to the Add bus.
