CELL XMIT TO:
Figure 24-2. Polling Phase and Selection Phase at Transmit Interface
Note that the active PHY (PHY N) is polled in octet P48. At this time, according to the UTOPIA Level 1
specification, the UT-CLAV signal of the PHY indicates the possibility of a subsequent cell transfer.
Polling of PHY N before octet P44 would be possible but it does not indicate availability of the next cell.
