102 of 202 Integrated Network Management Broadband Historical Overview
INM Broadband Release 4.1 PG OC 98-13 Issue 1.2
For a stand-alone INM workstation, simultaneous INM users can operate on
the INM via X terminals. Additional X terminals may be connected to the
INM, however there is a maximum of 10 simultaneous users that can be
operating on INM at any one time. Therefore, in a federated network, since the
maximum number of INM workstations is 25, the maximum number of users
that can be operating the network at one time increases to 250 (based on 5,500
NEs).
Four Integrated Network Management Servers can still simultaneously
monitor the same Controller subnetwork directly, however only one direct
connection from a single INM workstation to the controller is required since
the rest of the federated INM workstations can be indirectly connected to that
workstation through the federated network.
The introduction of indirect management via federated connections greatly
expands the number of INM users that have access to network data by
transferring the burden of resources and data distribution from the controller
to the INM.
Fault Management
Immediately after locating the subnetwork group with the troubled condition
and isolating the NE with the alarm condition, a user can obtain the detailed
information about the alarm condition(s) by displaying an Alarm Dialog
window. Detailed alarm information may be viewed by simply double-clicking
on the alarm balloon, as previously shown in Figure 4.
Once the user has quickly located the troubled NE and viewed the details of
the alarms associated to it, the user may then log directly into the affected NE
by simply double-clicking on the NE icon to further investigate and resolve the
problem. The GNB also allows you to login directly into the OPCs/MOAs in
the S/DMS TransportNode and S/DMS AccessNode system that the INM
Broadband is monitoring.
After investigating the cause of an alarm, the user may acknowledge the alarm
and take corrective action to clear the alarm status. The INM will propagate the
alarm acknowledgment performed by the user, on one GNB session, to all
other GNBs that are running on the same INM workstation. Once a user has
acknowledged an alarm, no other user may acknowledge the same alarm. The
alarm acknowledgment conveys to other INM users that an alarm has been
detected and acted upon. In order to keep records of any alarm
acknowledgment performed on an alarm in the network, audit trails are
generated by the INM Broadband to track the history of alarm
acknowledgments.
