DS1 Alert Traps

13-4
The ATLAS 550 supports RFC1406, the DS1 standard MIB, as well as the
ADTRAN DS1 MIB, an extension to RFC1406. The ADTRAN DS1 group al-
lows you to send traps for DS1 alarm failures (DS1 alarm traps) and perfor-
mance threshold crossing alerts (DS1 alert traps).
The ADTRAN DS1 extension MIB contains a DS1 Alarm Table which holds
entries that enable status bits to send an alarm trap. Each Alarm Table row
entry corresponds to a DS1 interface managed by the device. DS1 line status
is reported in the bit-encoded dsx1LineStatus object variable. Each trap rep-
resents a bit value equal to 1 change in the dsx1LineStatus. Table 13-2 de-
scribes the DS1 alarm traps supported by the ATLAS 550.
When enabled, the ATLAS 550 sends alarm traps to the each member of the
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 in the
adDS1LineArm variable equal to one and if adDS1AlarmEnable = On, then the
ATLAS 550 sends an alarm trap message. A single alarm trap message may
report multiple event changes.
The ATLAS 550 clears the event bits after sending the trap message or send-
ing the response to a Get request for the adDS1LineEvent variable.
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.
The ADTRAN DS1 extension MIB contains the DS1 Alert Table which holds
entries that enable event bits to send an alert trap. Each Alert Table row en-
try corresponds to a DS1 interface managed by the device. A single alert trap
may report multiple event changes.
RFC1406 also defines a series of Current and Total Alert threshold values.
You can enable the ATLAS 550 to send an Alert Trap to each member of the
trap destination list when accumulated error statistics exceed these
