dot3ExtPkgOptIfTable

This table defines the control and status indication objects 
for the optical interface of the EPON interface. Each object has 
a row for every virtual link denoted by the corresponding ifIndex. 
The LLID field, as defined in the [802.3ah] is a 2bytes register 
(15bits field and a broadcast bit) limiting the number of virtual 
links to 32768. Typically the number of expected virtual links in a 
PON is like the number of ONUs, which is 32-64, plus an additional 
entry for broadcast LLID (with a value of 0xffff). Although the optical 
interface is a physical interface, there is a row in the table for each 
virtual interface. The reason for having a separate row for each virtual 
link is that the OLT has a separate link for each one of the ONUs. For 
instance, ONUs could be in different distances with different link budgets 
and different receive powers, therefore having different power alarms. 
It is quite similar to a case of different physical interfaces.
