Performance Reports
Network performance is continuously monitored and
maintained in network registers (NET), in G.703 DTE
registers (DTE) and, if configured to do so, in far-end and
near-end port registers (Prtn, where n is 1, 2, 3, or 4).
Registers shown on the front panel LCD are listed in
Table 4-4
.
NET and DTE registers are status registers that collect
performance data for the previous 24-hour period.
Performance 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.
For 2-port and 4-port E1 NTUs, port performance is
continuously monitored and maintained in memory
registers when the port is configured to use EDL. The
E1 NTU 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.
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.
NOTE
The following procedure is an
example only. Screen displays
may vary depending on the
model and configuration of the
E1 NTU. The procedure for
displaying DTE and port registers
is similar to this example.
To display network (NET) performance,
