AIS
An increasing value of this statistic indicates that the network equipment directly connected to the
site is not getting correct transmission from the far-end network equipment and it notifies the site
about that fact.
Remote Alarm
An increasing value of this statistic indicates that the network equipment directly connected to the
site is not getting correct E1 transmissions from the Site Controller and notifies the Site Controller of
the error.
Frame alignment Loss
An increasing value of this statistic indicates that the E1 signal received by the site from the
connected network equipment lost frame alignment. Each incremental increase of the statistic
indicates that three or more frames have been received without alignment.
NOTICE: The growing value of the Second timer expired statistic is no reason for
concern. The Second timer expired value is incremented every second no matter if the
Site Link is up or down. The Second timer expired count does not indicate any Site Link
failure.
The HDLC statistics provide a running counter of HDLC frames transmitted and received on the site
link interface as shown by the "Good frames" counters. Incrementing counters with the absence of
incrementing error counters such as CRC/framing errors, Aborts, or Non octet aligned errors indicates
the correct transmission and reception of HDLC frames. Persistent large numbers of HDLC errors on
an interface configured for E1 indicates errors in the configuration of the E1 data timeslots.

The current configuration for frame relay, and the current state of the primary and backup PVC may be
determined using the status fr MMI command. If both PVCs are indicated as ACTIVE, the number
of state changes for each PVC, the time in the current state, and the time in an active state should be
inspected to determine the stability of the two PVCs as determined by the LMI link management
