Upgrading ISDN BRI Network Modules
Upgrading ISDN BRI Network Modules
If your Cisco 3600 series router contains an ISDN BRI network module (product numbers NM-4B-S/T,
NM-4B-U, NM-8B-S/T, or NM-8B-U) and a digital modem network module (product numbers
NM-6DM, NM-12DM, NM-18DM, NM-24DM, or NM-30DM), your ISDN BRI network module may
need to be upgraded to the minimum revision shown in
Earlier revisions of the ISDN BRI network module cannot send modem calls to the digital modem
network module.

If your BRI module is the wrong revision, you see a message similar to this one when the router boots:
The BRI network module in slot 0 is incompatible with the digital modems installed in the
router.
To determine the revision level, you can examine the network module itself (outside the router) or use
the Cisco IOS show diag command. The label on the module board should show a part number beginning
with 800-, corresponding to
to be upgraded, as does a BRI U module whose part number is lower than -06.
The output of the show diag command looks similar to the following:
Port adapter is analyzed
Port adapter insertion time unknown
