Connecting Cisco ISDN PRI Network Modules to the Network
Upgrading ISDN PRI Network Modules
If your Cisco 3600 series router contains a legacy ISDN PRI network module and a digital modem
network module (product numbers NM-6DM, NM-12DM, NM-18DM, NM-24DM, or NM-30DM), your
ISDN PRI network module may need to be upgraded to revision level -03 or higher. Earlier revisions of
ISDN PRI network modules cannot send modem calls to the digital modem network module.
Note Channelized T1/E1 PRI network modules with G.703 provide full support for Cisco digital modem
network modules.
If your PRI module is the wrong revision, you see a message similar to the following message when the
router boots:
The PRI 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- and ending with the revision level.
The output of the show diag command looks similar to the following:
Port adapter is analyzed
Port adapter insertion time unknown
Hardware revision 1.0 Board revision A0
Serial number 4152626 Part number 800-01236-01
Test history 0x0 RMA number 00-00-00
EEPROM format version 1
EEPROM contents (hex):
0x20: 01 26 01 00 00 3F 5D 32 50 04 CC 01 00 00 00 00
0x30: 50 00 00 00 96 11 04 17 FF FF FF FF FF FF FF FF
