Teardown state
SLS transitions to the Teardown state whenever the following events occur:
• The Branch Gateway administrator uses the set sls disable command from the
Branch Gateway CLI or manual MIB browser using the SNMP read/write attribute
avSurvAdminState.
• The Branch Gateway closes the SLS socket after maintenance determines that it has
completed an H.248 registration with the primary MGC.
• SLS determines that it needs to unregister with the Branch Gateway due to internal error
conditions.
