T1E1 ATM Port Configuration
If you are running T1 ATM on a Vanguard 6435 or 6455 Series product, the AAM
port may not function after upgrading to release 6.0.R00A or greater (when certain
parameters are not at default). You must have local CTP access to the node if this is
the case. Do not upgrade to release 6.0.R00A if you have no other way to access the
CTP than through ATM. The ATM connection could be down after booting in
Release 6.0.R00A or greater.
You must have local CTP access if the following parameters are not configured as
follows (prior to the upgrade):
If these parameters are not set at default, you must reconfigure all AAM ports after
release 6.0.R00A or greater has been booted on-line and then reboot the node again.
All AAM station configurations are correctly transferred in the upgrade and will
function once the AAM port is reconfigured properly.
