Chapter 15 Performance Monitoring

15.6.6 TXP_MR_2.5G and TXPP_MR_2.5G Card Performance Monitoring Parameters

MS-BBER

Multiplex Section Background Block Error Ratio (MS-BBER) is the ratio
of BBE to total blocks in available time during a fixed measurement
interval. The count of total blocks excludes all blocks during SESs.

MS-UAS

Multiplex Section Unavailable Seconds (MS-UAS) is a count of the
seconds when the section was unavailable. A section becomes unavailable
when ten consecutive seconds occur that qualify as MS-SESs, and it
continues to be unavailable until ten consecutive seconds occur that do not
qualify as MS-SESs. When the condition is entered, MS-SESs decrement
and then count toward MS-UAS.

MS-EB

Multiplex Section Errored Block (MS-EB) indicates that one or more bits
are in error within a block.

Parameter

Definition

Valid Packets

A count of received packets that contain non-errored data code groups that
have start and end delimiters.

Invalid Packets

A count of received packets that contain errored data code groups that
have start and end delimiters.

Code Group Violations

A count of received code groups that do not contain a start or end
delimiter.

Idle Ordered Sets

A count of received packets containing idle ordered sets.

Non-Idle Ordered Sets

A count of received packets containing nonidle ordered sets.

Data Code Groups

A count of received data code groups that do not contain ordered sets.

Note

Enterprise System Connection (ESCON), DV6000, SDI/D1 video, and high definition
television (HDTV) client signals are unframed payload data types. If the configured payload
data type is unframed, line threshold provisioning and performance monitoring are not
available.

BBE-SM

Section Monitoring Background Block Errors (BBE-SM) indicates the
number of background block errors recorded in the OTN section during
the PM time interval.

ES-SM

Section Monitoring Errored Seconds (ES-SM) indicates the errored
seconds recorded in the OTN section during the PM time interval.

SES-SM

Section Monitoring Severely Errored Seconds (SES-SM) indicates the
severely errored seconds recorded in the OTN section during the PM time
interval.
