Performance Reports

When the network interface is configured for ESF operation, network performance is continuously monitored and maintained in two sets of aggregate registers:

TCarrier 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 7-3, 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.

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:

Tfar-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.
