Arris D31 signed firmware necessary?

Short Question:
For the Arris DG3450 TG3452, and TM3402 modems, which variant of the firmware should be used? NA or D31?

Long Version:
We're getting ready to start testing DOCSIS 3.1 modems and adding the 3.1 licensing to an Arris E6000 CMTS. We've purchased a few D3.1 modems (Arris CM8200, DG3450, TG3452, TM3402) for evaluation. We got access to the modem firmware on Friday and, after downloading, I see that the DG3450, TG3452, and TM3402 modems all have two variants, an "NA" (D3.0 North America) and "D31" (DOCSIS 3.1).
The firmware guide clarifies what the file naming is for but, so far, I can't find when either is required.
We'll initially be testing with just 3.0 functionality in order to make any changes needed in provisioning and, once that is done, we'll begin deploying these to customers with the highest level service package so that, when we add the 3.1 license in a few months, we don't need to go swap as many modems.

The NA firmware is needed if you want to run in 3.0 bonded mode. The D31 is needed for modems running OFDM in 3.1 mode. Another thing I have found out is the Arris software table no longer works to load firmware on the DG3450 and TG3452. I haven't tried the other two models yet. To load firmware on these, you have to go back to old school TLV's for upgrade server and upgrade file name. Below are the 3 lines you will need to get firmware downloads working. is the current version for the two gateways, but another revision is supposed to be GA soon to fix some SNMP polling issues.

SnmpMib = docsDevSwAdminStatus.0 allowProvisioningUpgrade
UpgradeServer = X.X.X.X
UpgradeFileName = "AR01.01.106.13_073018_70.NCS.10.7.NA.simg"

response from arris

Got info back from Arris on this. It comes down to which CVC you use in the config file. If using the DOCSIS 3.1 CVC, you must use the 'd31' variant of the firmware.



do you also have access to the TG3442 firmware? I am trying to get it from Arris but they are unable to help me and send me back and forth.

Any help is really appreciated!
