OOFE:
The OOFE bit is an interrupt enable for the out of frame alarm. When OOFE
is set to logic one, an interrupt is generated when the out of frame alarm
changes state.
LOFE:
The LOFE bit is an interrupt enable for the loss of frame alarm. When LOFE
is set to logic one, an interrupt is generated when the loss of frame alarm
changes state.
LOSE:
The LOSE bit is an interrupt enable for the loss of signal alarm. When LOSE
is set to logic one, an interrupt is generated when the loss of signal alarm
changes state.
BIPEE:
The BIPEE bit is an interrupt enable for the section BIP-8 errors. When
BIPEE is set to logic one, an interrupt is generated when a section BIP-8 error
(B1) is detected.
ALGO2:
The ALGO2 bit position selects the framing algorithm used to confirm and
maintain the frame alignment. When a logic one is written to the ALGO2 bit
position, the framer is enabled to use the second of the framing algorithms
where only the first A1 framing byte and the first 4 bits of the last A2 framing
byte (12 bits total) are examined. This algorithm examines only 12 bits of the
framing pattern regardless of the STS mode; all other framing bits are
ignored. When a logic zero is written to the ALGO2 bit position, the framer is
