provided to facilitate picking up new or offline units. This migration tool
includes temporary control parameters for Hub units that allow the operator to
select an operation mode that is compatible with Remotes running v1.5.2 (or
earlier) firmware. When this operation mode is chosen for the TDM outbound
and the appropriate Burst Controller(s), communications with v1.5.2 (or earlier)
straggler/offline Remotes will be restored. At this point they can be upgraded to
v1.5.3, restoring total network-wide communications.
Note that communications with all Remotes with the upgraded firmware version
will be lost when this backwards compatibility migration control is initiated.
Until migration is completed, this will represent a temporary network outage to
all Remotes connected to the TDM outbound. In networks with a DVB
outbound, only those Remotes associated (grouped) with the Burst Controller
set to v1.5.2 compatibility will lose communications.
Great care should be exercised in following these steps as outlined in this docu-
ment. It is important to remember that network communications will not be
effected until the units are rebooted to v1.5.3 router code. The last section of
this document addresses recovering stragglers/offline remotes.
