Performance Reports
When the network interface is configured for ESF operation, network performance
is continuously monitored and maintained in two sets of aggregate registers:
Carrier Network Interface Registers (Telco) and User Network Interface Registers
(User). The User registers contain an extra status register (Status Event).
Registers shown on the front panel LCD are listed in
Table 4-3, Performance
Registers . These 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 DSU/CSUs, port performance is continuously monitored and
maintained in memory registers when the port is configured to use EDL. The
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. 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 DSU/CSU. The
procedures for displaying Telco and port registers are similar to this example.
Test in progress A test is currently active. Select Tstat (in the Stat branch) to display
more test information.
Modem
Connected The integral modem is currently connected. This message is only
displayed for standalone DSU/CSUs.
Master Clk fail The master clock has failed. Timing for the DSU/CSU is provided by
the internal clock.
DSU Operational This message only appears if there are no valid alarm or status
messages.
