ADTRAN 1200305L1 system manual RED, Yellow, or Blue alarms, When network is out of alarm

Section 4, User Interface Guide ATLAS 550 System Manual

DIAL PLAN (CKT BACKUP) > USER TERM > IFCE CONFIG > FORCE MODE

Write security: 3; Read security: 5

This forces the backup state of this endpoint. This is a configuration setting, so it will retain its value until it is changed. To temporarily force an endpoint into backup, or to force a restore, try the Manual activator.

DIAL PLAN (CKT BACKUP) > USER TERM > IFCE CONFIG > BACKUP CRITERIA

Write security: 3; Read security: 5

Criteria for automatic backup. Note that this setting affects the available options for RESTORE CRITERIA.

NET/DATA FAIL	DBU is initiated when either the network fails (possible causes include Red, Yellow,
	Blue, or LOS alarms) or when the Nx56/64 module detects a loss of data transitions
	on the V.35 interface. If Net/Data Fail is selected, the V.35 Nx INBAND option
	must be ON. The remote TSU INBAND option must also be enabled.

When BACKUP CRITERIA is configured for NET/DATA FAIL, the RESTORE CRITERIA must be

MANUAL ONLY.

NET FAIL	DBU is initiated when there is a network failure. Possible causes include LOS,
	RED, Yellow, or Blue alarms.
MANUAL	The ATLAS will never initiate DBU until it is manually set to do so.

DIAL PLAN (CKT BACKUP) > USER TERM > IFCE CONFIG > RESTORE CRITERIA

Write security: 3; Read security: 5

This only applies to originating endpoints. These are criteria for automatically coming out of backup. Note that NETWORK SUCCESS is only available when a backup criterion is not NET/DATA FAIL.

NET SUCCESS	When network is out of alarm
MANUAL ONLY	Only by the Manual activator

DIAL PLAN (CKT BACKUP) > USER TERM > IFCE CONFIG > STARTUP DELAY

Write security: 3; Read security: 5

The amount of time to wait after creating or changing the endpoint before allowing backup.

DIAL PLAN (CKT BACKUP) > USER TERM > IFCE CONFIG > BACKUP DELAY

Write security: 3; Read security: 5

The amount of time to delay after detecting an alarm before going into backup. This only applies to originating endpoints. If the circuit comes out of alarm before this time has expired, the endpoint will not go into backup.
