38.6.4.1 MTP3/M3UA Operational Status
The Operational Status of the MTP3/M3UA application may be determined by
inspecting the Operational Status of the following entities:
Trunk – indicates status of the MTP1 link layer
SS7 Data Link – indicates status of the MTP2 link layer
SS7 Linkset – indicates status of the SS7 Linkset
SS7 Routeset – indicates status of the SS7 Routeset
SS7 Node – indicates status of the SS7 Node
38.6.4.2 Online Provisioning
The configuration of the MTP3/M3UA application can be modified online.
See the 'Configuring the MTP3/M3UA Application' on page 20 for the full list of entities
that must be configured and the specific parameter descriptions and provisioning
policies.
The LOCK/UNLOCK operations are not supported on the MTP3 Group and SS7
Node. Perform the operation on the Media Gateway board. In particular, when you
define a new SS7 Node, you must lock/unlock the Media Gateway board to bring the
SS7 Node into service (unlock it).
Due to hierarchical and cross-reference dependencies between MTP3 application
entities (SS7 Node, SS7 Routeset, SS7 Linkset and SS7 Data Link), specific
maintenance operations must be performed in the following order:
Unlock of SS7 Linkset and Routeset is not allowed when a SS7 Node is locked.
Unlock of SS7 Linkset is not allowed when no SS7 Data Links are attached to it
(via use of SS7 LinksetLink MOs) and vice versa.
To simplify the online configuration, lock/unlock operations are not supported on
“virtual connector” MOs, namely SS7 Linkset Link and SS7 Route. Use lock/unlock
actions on SS7 Data Link and SS7 Linksets instead.
Since the MTP3/M3UA application involves many configuration entities, ensure that
while performing the online configuration, you unlock all newly defined entities to bring
the application to service. Consider use of “Recursive Unlock” action on the SS7 Node
instead of performing “Unlock” action on the SS7 Node, SS7 Routeset, SS7 Linkset
and SS7 Data Link. Note, however, that the use of an “Unlock” action on specific MO
provides better control of the configuration and a more simple way of correcting
configuration errors.
Some of the configuration parameters (e.g. in SS7 Data Link and SS7 Linkset entities)
have the Offline_create provisioning type. To modify them, either lock the Media
Gateway board or delete the entity (e.g. SS7 Data Link or SS7 Linkset) and define a
new entity.
