PLANET EPL-1000 - Manual (Page 33)

4. OLT System Configuration
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.
