the v1.5.3 firmware will lose communications during this time, so a planned
maintenance outage is necessary.
It is only necessary to download 1 image of the Router to v1.5.3 and reset the
Remotes in order for them to rejoin the network, unless the associated Burst
Controller is running BFAT. If that is the case, it is suggested that BFAT be
disabled, and that the STDMA Preamble be increased. This will allow restora-
tion of communications to all Remotes, with reduced performance. Once the
straggler Remote(s) have v1.5.1 modem code loaded, BFAT can be re-enabled.
The appropriate Preamble length will be reset automatically when BFAT is
running.

Setting v1.5.2 Compatibility in Hub Modems

Telnet into the TDM Outbound and Burst Controller Hub units associated with
the straggler Remote(s) and follow the steps below.
