Interval Description

Totals Description

 

 

 

Event

Error events counter. An error event is a frame

N/A

 

with either a Cyclic Redundancy Check (CRC)

 

 

error or an Out Of Frame (OOF) event. The

 

 

maximum count is 65,535. This register is only

 

 

reset as a result of a Clear Performance

 

 

Register command. This register is valid for the

 

 

current interval only.

 

 

 

 

CurTimer

Current interval timer. This register records the

N/A

 

number of seconds in the current 15-minute

 

 

interval. The maximum is 900 seconds. This

 

 

register is valid for the current interval only.

 

 

 

 

VldIntvl

N/A

Valid interval total. Records the number of valid

 

 

15-minute intervals in the previous x hours, where x

 

 

is 24 hours for aggregate performance and 8 hours

 

 

for port performance. This register is not valid for the

 

 

current interval.

 

 

 

ES

The number of errored seconds for the current

The total number of errored seconds for the previous

 

interval. An errored second is any second with

x hours, where x is 24 hours for aggregate

 

one or more of the following: errored frame

performance and 8 hours for port performance.

 

alignment, CRC error, Loss of Signal (LOS),

 

 

Alarm Indication Signal (AIS), or Loss of Frame

 

 

(LOF). The maximum is 900 seconds.

 

 

 

 

UAS

The number of unavailable seconds for the

The total number of unavailable seconds for the

 

current interval. An unavailable second is any

previous x hours, where x is 24 hours for aggregate

 

one second interval when service is

performance and 8 hours for port performance.

 

unavailable. The maximum is 900 seconds.

(Detection occurs with 10 consecutive unavailable

 

 

seconds.)

 

 

 

SES

The number of severely errored seconds for the

The total number of severely errored seconds for the

 

current interval. For E1 or DTE registers, a

previous x hours, where x is 24 hours for aggregate

 

severely errored second is any second with 805

performance and 8 hours for port performance.

 

or more CRC errors, 16 or more errored frame

 

 

alignment signal events, or one or more LOS,

 

 

AIS, or OOF event. For port registers, a

 

 

severely errored second is any second with 320

 

 

or more CRC errors, or one or more OOF

 

 

event. The maximum is 900 seconds.

 

 

 

 

BES

The number of bursty errored seconds for the

The total number of bursty errored seconds for the

 

current interval. For E1 or DTE registers, a

previous x hours, where x is 24 hours for aggregate

 

bursty errored second is any second with more

performance and 8 hours for port performance.

 

than one, but less than 805, CRC errors when

 

 

in CRC4 mode, or more than one, but less than

 

 

16, errored frame alignment signals when in

 

 

non-CRC4 mode. For port registers, a bursty

 

 

errored second is any second with more than

 

 

one, but less that 320, CRC errors. The

 

 

maximum is 900 seconds.
