32.1.1 Working with the V5.2 Access Gateway
The following chapters describe the maintenance actions available on V5.2 entities
that may be used to maintain and monitor V5.2 Access Gateway application.
32.1.1.1 V5.2 Interface Status and Maintenance Actions
The V5.2 Interface uses a management model that is slightly different from the other
Mediant 8000 entities. The standard Administrative State attribute and
corresponding Unlock/Lock actions are used to add/remove the configuration of
thecorresponding V5.2 Interface to/from the corresponding Media Gateway board. The
following additional attributes are used to indicate the actual and desired state of the
service provided by the V5.2 Interface:

Interface Admin State – indicates the desired service state on the V5.2
Interface; valid values are:
• Offline – indicates the user request to stop the service on the specific V5.2
Interface
• In Service – indicates the user request to start the service on the specific
V5.2 Interface

Interface Operational State – indicates the actual service state on the V5.2
Interface; valid values are:
• Offline – service is not provided due to local "Offline" request by user
• Busy – service is not provided due to some communication error with the far-
end
In Service – V5.2 Interface is "in service" The following maintenance actions are
supported on the V5.2 Interface:

Add / Remove – adds/removes V5.2 Interface

Unlock / Lock – adds/removes the configuration of the corresponding V5.2
Interface to/from the corresponding Media Gateway board (note that it's not
enough to Unlock the V5.2 Interface to bring it to service – you must also use In
Service action described below)

In Service / Offline – indicates the user request to start/stop the service on the
corresponding V5.2 Interface

Protection Switchover – user-initiated switchover between the primary and the
secondary signaling V5.2 links; applicable only when the Interface's Operational
State is "In Service". The Mediant 8000 also performs automatic switchover
between signaling links when a problem at the physical or data link layers is
detected. However there is no automatic switchback when the failed link
recovers.
