sequence and multiple LLIDs may be authenticated simultaneously.
Step 4: Having discovered the known managed entities the GUI will next query the TK3721
for the list of blocked links. These links will be displayed in the list of unassociated links in
the managed entity status window. If the ONU is connected to the TK3721 and operating
properly, then unblocking a LLID will cause a new ONU to appear in the entity status
window. The LLID will be associated with this new ONU.
Step 5: After the GUI has finished querying the OLT, it will remain in the idle state until the
user performs some action. In the idle state the GUI will audit the OLT for alarm messages if
configured to do so, otherwise it will not send any Host Interface Messages until the GUI
operator directs it to do so, by initiating a query or provisioning action.
3.2.3 Note on the GUI data Path
The GUIs Data Path consists of simple non-blocking queuing mechanism that achieves
very good utilization of OLT recourses. However in such a system there is no set sequence
in which messages will be issued to the OLT. Thus that depending on very minor timing
differences between command response times, the GUI event log trace will be different. It is
important to note that all host interface messages are required to encapsulate a complete
set of provisioning operations and therefore do not require that provisioning actions be
performed in any set sequence.
