Notes
(1)
The lost GEM fragment counter supports downstream direction only. Upstream direction is not
supported.
(2)
A 5 second polling window limitation exists on the ONT, therefore the margin of error for each
15-min window is 5 seconds
Performance monitoring statistics for Package E ONTs
The following section identifies the supported performance monitoring statistics for
Package E type ONTs. A check mark indicates the statistic is supported on that ONT.
An empty cell indicates the statistic is not supported. A cell without a check mark
indicates that the counter is not applicable to that type of ONT. The following tables
are categorized by supported alarm types:
• Table 4-24 provides statistics for ONTENET type counters
