The MMI provides the following maintenance features:
• configurable alarm parameters
• E1-link problem indicator
• current and historical E1-link performance reports
• E1 verification and fault isolation testing
• configuration of A\B bits (North American Standard, Australian P2, or customized settings
are available)
Alarms
The MMI may be used to activate alarms for the following E1-link conditions:
• excessive bit-error rate,
• frame-slip errors,
• out-of-frame,
• loss-of-signal, and
• blue alarm.
Preset thresholds and error durations trip LEI alarm notifications. For descriptions of each of
these E1-link alarm conditions, see
Performance counters and reporting
on page 237. For
instructions on how to set alarm parameters, see
on page 227. For information
about accessing alarm reporting, see
on page 236,
on
page 237 and
on page 238.
Two levels of alarm severity exist for bit errors. Different threshold and duration settings must
be established for each level.
When the first level of severity is reached (alarm level 1), the MMI causes the following:
• the external alarm hardware activates
• the RED ALARM LED on the faceplate is lit
• an alarm message is displayed on the MMI terminal
• an entry is created in the alarm log and printed to the MMI port
When the second level of severity is reached (alarm level 2), the MMI performs all functions
at alarm level 1. In addition, the LEI enters line-conditioning mode. In this mode, the LEI sends
either "on-hook" or "off-hook" signals for all 30 ports to the CS 1000E, CS 1000M, and Meridian
1, depending on how the dip switch for line processing is set (dip switch 2, position 6). See
Table 90: LEI card - E1 Switch 2 (S2) dip switch settings
on page 210.
If the MMI detects E1-link failures for any of the other conditions monitored (out-of-frame,
excess frame slips, loss-of-signal, and blue alarm condition), the LEI automatically performs
all alarm level 2 functions. The MMI also sends a yellow alarm to the far-end LTU. Alarms may
