Table 56 SS7 MTP 2 State Information Fields
State Description Possible Values
MTP2LSC Indicates the overall status of the
link.
OOS—The link is Out-of-Service.
INITIAL_ALIGNMENT—The link is
in a transitional link alignment state.
ALIGNED_READY—The link is in a
transitional link alignment state.
ALIGNED_NOT_READY—The link
is in a transitional link alignment state.
INSERVICE—The link is in service.
PROCESSOR_OUTAGE—There is an
outage in the local processor. This state
implies that the link has been aligned.
POWER_OFF—It is possible you don’t
have the I/O memory set to at least 40
percent. There may not be enough
memory for the SS7 MTP2 signaling.
MTP2IAC Indicates the status of the initial
alignment control state machine.
IDLE—The state machine is idle. It is
not aligning the link.
NOT_ALIGNED—The state machine
has begun the alignment process.
ALIGNED— The link has exchanged
the alignment handshake with the
remote device.
PROVING—The link alignment is
being proven. This is a waiting period
before the LSC state changes to
INSERVICE.
MTP2TXC Indicates the status of the
transmission control state
machine.
IDLE—The state machine is inactive.
INSERVICE—The state machine is the
active transmitter.
MTP2RC Indicates the status of the receive
control state machine.
IDLE—The state machine is inactive.
INSERVICE—The state machine is the
active receiver.
MTP2SUERM Indicates the status of the signal
unit error monitor (SUERM).
IDLE—The state machine is inactive.
MONITORING—The SUERM is
active. SUERM uses a leaky-bucket
algorithm to track link errors while the
link is in service. If the number of link
errors reaches the threshold, the link is
taken out of service.
