DS1 Alert Traps
11-4
ATLAS supports RFC1406, the DS1 standard MIB, as well as the ADTRAN
DS1 MIB, an extension to RFC1406. The ADTRAN DS1 group lets you send
traps for DS1 Alarm Failures and Performance Threshold Crossing Alerts.
The DS1 Alarm Table, defined in the ADTRAN DS1 extension MIB, contains
entries that enable the status bits to send an Alarm Trap message. Each
Alarm Table row entry corresponds to a DS1 interface managed by the de-
vice. The DS1 Alert Table, also defined in the ADTRAN DS1 MIB, contains
similar entries for controlling the Alert Traps.
DS1 line status is reported in the bit-encoded dsx1LineStatus object variable.
Each trap represents a bit value = 1 change in dsx1LineStatus. Table 11-3 de-
scribes the DS1 alarm traps supported by ATLAS 810
Severity
Warning
No alarms are present.
Minor
The Far End is experiencing Red Alarm
(a.k.a. Yellow Alarm).
Warning
The Near End is sending Loss Frame Indication
(a.k.a. Yellow Alarm).
Minor
The Far End is sending Alarm Indication Signal
(a.k.a. Blue Alarm).
Warning
The Near End is sending Alarm Indication Signal
(a.k.a. Blue Alarm).
Major
The Near End is experiencing Loss of Frame
(a.k.a. Red Alarm).
Major
The Near End is experiencing Loss of Signal.
When enabled, ATLAS 810
trap destination list upon detecting status bit changes in dsx1LineStatus. Each
status change sets an event bit = 1 in the adDS1LineEvent variable in the DS1
alarm table. If you have previously set the corresponding enable bit = 1 in the
adDS1LineArm variable and adDS1AlarmEnable = On, then ATLAS 810
sends an alarm trap message. A single alarm trap message may report mul-
tiple event changes. ATLAS 810
trap message or sending the response to a Get request for the adDS1LineEvent
variable.
RFC1406 also defines a series of Current and Total Alert threshold values.
