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.

Table 3-11

(1 of 2)

Performance Registers

Event=xx,xxx ESF error events counter. An error event is an

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.

N/A

CurTimer Current interval timer. Records the number of

seconds in the current 15-minute interval

(maximum 900 seconds). This register is valid

only for the current interval.

N/A

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

interval (any second with one or more ESF

error events \M maximum 900 seconds).

The total number of errored seconds for the previous

24 hours (maximum 65,535 seconds).

UAS The number of unavailable seconds for the

current interval (any one second interval when

service is unavailable, maximum 900 seconds).

The total number of unavailable seconds for the

previous 24 hours (maximum 65,535 seconds).

SES The number of severely errored seconds for the

current interval (any second with 320 or more

CRC errors or one or more OOF event,

maximum 900 seconds).

The total number of severely errored seconds for the

previous 24 hours (maximum 65,535 seconds).

BES The number of bursty errored seconds for the

current interval (any second with more than

one, but less than 320 CRC error, maximum

900 seconds).

The total number of bursty errored seconds for the

previous 24 hours (maximum 65,535).

LOFC The loss of frame (LOF) count for the current

interval (a count of the number of times that an

LOF is declared, maximum 255 times).

The total loss of frame count for the previous 24 hours

(maximum 255).
