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. 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.
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.
