Figure 45 TUPP with External NSE
When an external NSE is used, CCB is bypassed. Ingress MSU EJ0 delay value is 0 clocks if
NSE is only talking to other TUPP 2488s. If there are also SBS devices concerned, then EJ0 is
IC1FP for those SBS devices and the delay is the time between EJ0 and input to TUPP 2488s
Ingress MSU. Note that all inputs to DCB within NSE must arrive at the same time. CCB
internal delay is to dictate when the J0FP to the RCML block should be sent.
