Performance Monitor - Receive Slip Counter (8-bit Counter)
These Reset-Upon-Read bit fields reflect the cumulative number of
instances that Receive Slip events have been detected by the E1
Framer since the last read of this register.
N
OTE
:
A slip event is defined as a replication or deletion of a E1
frame by the receive slip buffer.

Performance Monitor - Receive Loss of Frame Counter (8-bit
Counter)
These Reset-Upon-Read bit fields reflect the cumulative number of
instances that Receive Loss of Frame condition have been detected
by the E1 Framer since the last read of this register.
N
OTE
:
This counter counts once every time the Loss of Frame
condition is declared. This counter provides the capability to
measure an accumulation of short failure events.

Performance Monitor - Receive Change of Frame Alignment
Counter (8-bit Counter)
These Reset-Upon-Read bit fields reflect the cumulative number of
instances that Receive Change of Framing Alignment have been
detected by the E1 Framer since the last read of this register.
N
OTE
:
Change of Framing Alignment (COFA) is declared when the
newly-locked framing pattern is different from the one
offered by off-line framer.
