Notes
(1)
For the modular ONT, the count PM_VLINE_LOFS represents the loss of frame seconds.
(2)
For the VDSL2 LP MDU, the count PM_VLINE_LOFS represents the loss of frame failures.
(3)
The performance monitoring parameter PM_VLINE_REINIT includes these counters: modem 
reinitializations, initialization failures, and initialization time-outs.
(4)
The performance monitoring parameter PM_VCHNL_RXBLK includes these counters: count of 
received blocks (fast), code violations, and forward error corrections. Only the count of received
