Paradyne 316x manual Performance Report, of Performance Registers, Interval Description

Operation

Performance Report

Network performance is continuously monitored and maintained in internal memory registers when the network interface is configured for ESF operation. The DSU/CSU maintains two sets of registers: Carrier Network Interface Registers (Telco) and User Network Interface Registers (User). The User registers contain an extra status register (Status Event).

These registers are accumulators or status registers that collect performance data for the previous 24-hour period.

Registers shown on the front panel LCD are listed in Table 3-11. This data is updated in 15-minute intervals. After 15 minutes, the current interval is rolled over into a set of 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. The relationship of the registers is shown in Figure 3-35.

Performance Registers

Register	Interval Description	Totals Description
Event=xx,xxx	ESF error events counter. An error event is an	N/A
	ESF frame with either a CRC error or an OOF
	event. Maximum count is 65,535. This register
	must be reset via a reset command from the
	network. This register is valid for the current
	interval only.
CurTimer	Current interval timer. Records the number of	N/A
	seconds in the current 15-minute interval
	(maximum 900 seconds). This register is valid
	only for the current interval.
VldIntvl=xx	N/A	Valid interval total. Records the number of valid
		15-minute intervals in the previous 24 hours
		(maximum 96 intervals). This register is valid for the
		24-hour total and the 15-minute interval only.
ES	The number of errored seconds for the current	The total number of errored seconds for the previous
	interval (any second with one or more ESF	24 hours (maximum 65,535 seconds).

UAS	The number of unavailable seconds for the	The total number of unavailable seconds for the
	current interval (any one second interval when	previous 24 hours (maximum 65,535 seconds).
