Network Performance Reports
Network performance is continuously monitored and
maintained in network aggregate registers (NET) and, if
configured for EDL, in far-end and near-end port
registers.
Network aggregate registers (NET) are status registers
that collect performance data for the previous 24-hour
period. Registers shown on the front panel LCD are listed
in Table 4-3. Aggregate data is updated in 15-minute
intervals. After 15 minutes, the current interval is rolled
over into a set of accumulator registers that represent the
previous 96 15-minute intervals for the register. An
interval total of how many of the 96 registers contain
valid data is also kept, as well as a 24-hour total for each
accumulator register.
Network port performance is continuously monitored
and maintained in internal memory registers when the port
interface is configured to use EDL. The E1 DSU/CSU
maintains two sets of port registers for each synchronous
data port: far-end port registers and near-end port
registers. These registers are status registers that collect
performance data for the previous 8-hour period.
Registers shown on the front panel LCD are listed in
Table 4-3. Port data is updated in 15-minute intervals.
After 15 minutes, the current interval is rolled over into a
set of accumulator registers that represent the previous 32
15-minute intervals for the register. An interval total of
how many of the 32 registers contain valid data is also
kept, as well as a 8-hour total for each accumulator
register.
