First of 86 columns occupied by  
TU3 carried in TUG3 #1 of an  
STM-1 stream  
First of 3 columns occupied by  
TU11 #1 of TUG2 #1 of  
Last of 4 columns  
occupied by TU12 #3  
of TUG2 #7 of TUG3 #3  
of an STM-1 stream  
TUG3 #2 of an STM-1 stream  
(column set is 20, 104, 188)  
(column set is 81, 144, 207, 270)  
In Figure 15 above, the H1 to H3 byte in column 13 form the TU3 offset pointer.  
The H1 to H3 bytes in columns 14 and 15 are null pointer indications (NPI) for  
TUG3 #2 and #3.  
13.5 Bypass Options  
The three tributary payload processors (VTPP) in each of the four STM-1 (STS-3)  
tributary processors (STP) in the TUPP+622 may be individually disabled or  
bypassed using the corresponding TUGEN or TUGBYP register bits, respectively.  
This enables the TUPP+622 to support STS-1/AU3/TUG3 level bypass  
operation. Incoming data destined to a disabled or bypassed processor is re-  
transmitted unchanged to the outgoing data after some delay. The amount of  
delay is fixed when the 19.44 MHz STM-1 interface mode for both the incoming  
and outgoing interfaces are selected. When either or both incoming and outgoing  
interfaces are set to the 77.76 MHz STM-4 interface mode, the amount of delay  
is also dependent on the relative phase of the corresponding incoming frame  
pulse (IC1J1) and the GSCLK frame pulse (GSCLK_FP). Figure 26 and Figure  
27 show the functional timing of possible bypass delays for the STM-1 (STS-3)  
and the STM-4 (STS-12) interface modes, respectively.  
For STM-1 (AU4) bypass operation, all three tributary payload processors  
(VTPP) of the corresponding STM-1 (STS-3) tributary processor (STP) must be  
bypassed by setting the TUGEN and TUGBYP bits high. Tributary performance  
monitoring of the STM-1 (AU4) stream remains active in this bypass  
configuration.
