The source of the E1 alarms in Table 5-15 is one of the following interfaces: ATM0/2 through ATM0/9
(the trunk).
The source of the IMA link alarms in Table 5-16 is one of the following interfaces: ATM0/2
through ATM0/9.
Table 5-15 E1 Network Interface Alarms
Alarm Severity Description
LOS Detected Critical The E1 line has detected a loss of signal at the framer.
AIS Received Critical The E1 line is receiving an alarm indication signal.
RAI Received Critical The E1 line is receiving a remote alarm indication.
LOF Detected
(red alarm)
Critical The E1 line has detected a loss of frame error.

Table 5-16 IMA Link Network Interface Alarms
Alarm Severity Description
LOS Detected Critical The IMA link has detected Loss of Signal at the framer.
LOF Detected Critical The IMA link has detected a Physical Layer
Convergence Procedure Loss of Frame error.
AIS Received Critical The IMA link is receiving an Alarm Indication Signal.
RAI Received Critical The IMA link is receiving a remote alarm indication.
LCD Critical The IMA link is experiencing a loss of cell delineation.
LIF
1
Critical The IMA link is experiencing an LIF defect at the
near end.
LODS
2
Critical The link differential delay between the link and the
other links in the group is over the tolerable value for
link differential delay.
Rx Failed Critical A persistent detection of a defect at the receiver.
The criteria for entering the condition are
implementation specific.
Tx Link Misconnected Critical The Tx link is not connected to the same far end IMA
unit as the other Tx links in the group. The detection is
implementation specific.
Rx Link Misconnected Critical The Rx link is not connected to the same far end IMA
unit as the other Rx links in the group. The detection is
implementation specific.
Persistent NE
3
RDI-IMA Critical One of the available remote defect indicators (including
IMA link specific defect) is in the link-related “Link
Information” field.
Rx Fault Critical Implementation specific Rx fault declared at the
near end.
Tx Fault Critical Implementation specific Tx fault declared at the
near end.
