will cause the Apply button to be enabled allowing the GUI operator to apply the new provisioning to the managed entity.
3.1.2 Refresh Button
Button’s labeled refresh are never disabled. The action associated with a Refresh button is always to query the state of the
associated attribute. The result of a successful Refresh operation will be the same as if the panel is viewed for the first time. That
is, the OLT will query the managed entity associated with the panel, and if the operation completes the Apply Button will be
disabled.
3.1.3 Revert Button
The Revert Button had identical functionality to the Refresh button, but is semantically different. The idea behind the Revert
Button is that you can “revert” the panel’s state to the initial state of the panel prior to changing a GUI widget. Semantically, once
the apply button has been pressed it is not possible to revert. The Revert Buttons are currently being phased out in favor of the
Refresh Button.
3.1.4 Defaults Button
The Defaults Button is used to restore the managed entity to the default settings found in the Host Interface document. This
mechanism employs a “canned” Host Interface Message that will be issued to the OLT when the button action is invoked by left
clicking on the button.
For most commands a provisioning operation will also result in a subsequent query. In such cases the Apply Button will not be
disabled until the query operation completes. This audit mechanism ensures that the values displayed by the panel are the same
values stored in the relevant managed entity. For a few Host Interface Messages the granularity of the data is less than that of the
provisioned value.
Some Apply actions result in multiple commands being issued to the OLT.
4 GUI Panel Directory
This section describes the various panels found in the GUI, their function, and the method by which they may be used to test the
TK37XX Host Interface. The Panels are organized by entity and generally follow the order in which they appear in the associated
tabbed dialog box. In the rare case that the GUI abstracts some detail of the host interface, a flow chart of the message exchange
sequence is presented. Where the message performs a complex operation on the PON a related diagram may be present as a
visual aid. Most panels are subdivided into boxes with each box controlling exactly one host interface message. In most cases the
attributes are presented in the same order (as read from top to bottom) as that in which they appear in the Host Interface
Message. Thus for the most part the remainder of this document is simply a rehashing of the descriptions already available in the
Host Interface Document.
Force link rediscovery de-registers a Logical Link, while allowing it to re-register, as if it had been newly attached to the EPON
network. This command is useful, for example, when the Network operator wants to be able to force a re-arrival as part of their
debugging process to try to clear a problem, or to re-authenticate the user/ONU on that link.
The Block Link command prevents the given Logical Link (MAC address) from registering on the EPON. The OLT will simply ignore
registration requests from the blocked ONU. If the given ONU is already registered, the Logical Link will be deregistered, causing
the ONU to depart from the network. All further requests to register from the ONU are ignored until the Host issues an Unblock
Link command.
Up to 256 ONU labels (MAC addresses) can be on the block list at one time.
Link blocking is intended to be a temporary measure used to suspend service for reasons such as late payments or a troublesome
customer. When the issue has been resolved, or the ONU has been physically removed from the network and no longer requests
service, it can be removed from the blocked list with the Unblock Link command. If the ONU is still connected to the network and
attempting to register, the ONU will be once again allowed onto the network.
Service provisioning such as SLAs or Bridging modes are not affected by the Block Link command. Any ONU provisioning should be
deleted with the appropriate other commands, if desired. A blocked link will appear with a black status icon.
Please note the difference in the behavior with respect to the Block Link command where an Unblock Link is required to undo its
effect. Link Rediscovery invites the ONU to re-register this link with the network, while Block Link prevents the ONU from
returning on that link after deregistration.
