Note:
The relationship between the J1 and the SPE signals is shown for illustration purposes only. 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 TUG-3 added to the bus is shown for the TUG-3 designated as A. TUG-
3 B will occur one clock cycle later. TUG-3 C will occur two clock cycles later. There is always a
one byte delay between the AC1J1/ASPE input signals and the AD(7-0) output leads.
