Two VWIC3-2MFT's won't wake up in a 2921 router

Answered Question
Oct 16th, 2013
User Badges:

My Cisco 2921 came shipped with two preinstalled VWIC3-2MFT-T1/E1, and I had no problems adding it as MGCP gateway to my new CUCM BE6000 version 9.1. However, even though both VWIC3's appear nicely at show inventory, they seem completely dead. All LED's are dark, even when looping Tx-Rx.


show version gives "(C2900-UNIVERSALK9-M), Version 15.2(4)M3", which I think is sufficient for VWIC3. However, this is the situation right now:


show isdn status returns "Invalid input detected at..."

show controllers E1 returns no output at all

show mgcp endpoint returns no output at all


Any experts out there?

Thanks George, that helped. VWIC's came up with LEDs, but still no ISDN related commands seems to be valid. I've tried


show isdn status

debug isdn q931


Service Engine is in shutdown status. I didn't think that could have anything to do with this, but now I'm beginning to run out of ideas.

Problem solved !


George Thomas helped med bringing up the VWI3's, (see post above).


But the lack of ISDN commands was due to a missing license accept. After accepting EULA and a reboot, all cannels came up, and commands show isdn status and debug isdn q931 vere valid.


Thanks to everyone!
