Hello,
I have a CCME on the 1760 router with 3 VIC installed working OK:
Slot 0 - VIC ADSL ISDN
Slot 1 - VIC ADSL Pots
Slot 2 - Empty
Slot 3 - VIC2-2BRI-NT-TE
When I try to install a VIC2-2FXO on the slot 2, router detects the 2 voice VIC, but only the FXO VIC is configurable and the Slot 3 VIC don't work.
I have interchanged the slot 2 with the slot 3 without success..
In the initial config, the BRI VIC is associated on the "voice-card 3", but when i install the FXO VIC on the slot 2, the "voice-card 3" command disappears and only the "voice-card 2" is present.
regards
Gerard

Hi, likely you do not have enough DSP resources to support all the voice cards simultaneously.
If you do "show diag" you will see which model of PVDM256 do you have.

Hi p.bevilacqua,
With the "show diag" command show a PVDM-256K-4= DSP, so only 1 DSP.
On the DSP guide from the link below says:
---------------------
With a medium-complexity codec configured:
â¢One DSP can serve four analog voice ports.
â¢If one DSP serves only two analog ports (due to an odd number of 2-port analog VICs in the system), one BRI port (2 channels) can also be served by this DSP.
With a high-complexity codec configured:
â¢One DSP can serve two analog voice ports.
After the DSP channels are assigned to all the analog cards, the remaining unused DSP resources will first be assigned to the BRI ports and then assigned to the T1/E1 channels.
------------------
http://www.cisco.com/en/US/docs/routers/access/1700/1751/software/feature/guide/dsp_cn.html
The configuration tool result is:
"Minimum number of DSPs required to support the above configuration is 2"
So you are right and the router need more DSP.
Thank you for your fast and good answer
regards

No problem, that happens a lot.
Without reading too much CCO, -4 in the PVDM designation means 4 calls and 4 ports .
Thanks for the appreciation and good luck!
