P/F: Indicates whether the test result Passed or Failed.
%ES: Percentage of M.2100 Errored Seconds since the start
of the test. An errored second is any second with a Code, Bit,
Frame, Multiframe or CRC errors.
%SES: Percentage of M.2100 Severely Errored Seconds since
the start of the test. An M.2100 Severely Errored Second is any

second with >10
bit error rate, 10
multiframe or CRC bit errors, loss of frame, loss of pattern, syn-
chronization, or loss of signal.

E1 G.826 Screen
The ITU standard, specifies
required performance character-
istics of 2.048 Mbit/s lines. The
parameter definitions given in
G.826 are block-based. This
allows for convenient in-service
measurement.
The following definitions pertain to this screen:
BBE: A Background Block Error is an errored block not occurring
as part of a SES (Severely Errored Second).
%BBE: Percentage of Background Block Errors since the start of
the test, excluding all blocks during SES and unavailable time.
EB: Errored Block is a block containing 1 or more bit errors.
%EB: Percentage of Errored Blocks since the start of the test.
SES: Severely Errored Second is a 1 second period which con-
tains greater or equal to 30% errored blocks.
%SES: Percentage of Severely Errored Seconds since the start
of the test.
For other screen items, See Section 2.3.3.1.
