Note that in synchronous mode, the SF/ESF F-bits may have arbitrary alignment
with respect to the P1P0 phase alignment bits, due to possible frame slips at the
T1 level. However, CAS is always aligned to the P1P0 bits (i.e. in either
synchronous or asynchronous mode).
T1 tributary asynchronous timing is compensated via the V3 octet. T1 tributary
link rate adjustments are optionally passed across the SBI via the V4. T1
tributary alarm conditions are optionally passed across the SBI bus via the link
rate octet in the V4 location.
In synchronous mode the T1 tributary mapping is fixed to that shown in Table 17
and rate justifications are not possible using the V3 octet. The clock rate
