Paradyne 3800 Release Note page 18

Download Device Firmware (dndf)
The value 3900 dc is added to the Type of download field for Broadcast Download Clone over the
Diagnostic Channel in support of 3900 Series modems.
The input form that appears when 3900 dc download is specified contains the following fields:
Device
Link participation
This command supports the 3980, 3981, and 3982 modems with the same functionality as the
3800 Series modems.
The dndf command supports 3800Plus modems. This will require a different set of firmware
download files (with initial P) than those provided for 3800 Series modems (with initial A).
This command also supports 392xPlus modems. This will require a different set of firmware
download files (with initial M) than those provided for 391x modems (with initial G).
Enter the address of the extended tributary device to which this command will be sent.
Enter the type of diagnostic channel clone to remote download to be performed. Valid
entries are all and partial. Selecting all allows the download to be performed when all of
the Poll List Active link-attached remote modems are participating in the download
process. Selecting partial allows the download even if there are non-participating
modems in the Active Poll List. Selecting partial runs the risk of having modems with
different firmware versions in different tributaries being on the same line. A confirm
message will display asking you to continue or cancel.
Since diagnostic channel firmware download depends on the active poll list, the accuracy
of the active poll list is critical to the success of the download. Another confirm message
will display, asking you to verify the correctness of the active poll list before executing
the download.
