An existing customer has a 2911 Router with one E1 PRI ISDN connected (CSS). (VWIC3-1MFT-T1/E1)
The customer has a PVDM3-32 as far as hardware DSP recources goes.
The customer wants to add an additional card supporting 2FXS interfaces (VIC3-2FXS/DID)
Do the customer also need an additional DSP card for that?
Solved! Go to Solution.
Depends on how many E1 channels are used, and what other features are needed. Check:
The router only serves as an MGCP configured ISDN-Gateway.
Only G711 codec is in use.
I tried out your link and it seems to work, i would want an confirmation on my input:
I inputed the Router Model 2911
Slot0: VWIC3-1MFT-T1/E1 (E1)
The webpage prefilles voice channel values.
I fill in the same number of channels as "low Complexity". (30 + 2)
(Only G711 codec used).
No additional services.
If everything is correct that means that the current PVDM32 is enough.
