Cisco 4431 NIM-xMFT-T1/E1 or NIM-xCE1T1-PRI max usable

I have scoured the documentation for the different types of cards and as many datasheets as I could possibly find. I cannot locate a specific place that dictates exactly how many individual serial circuits are able to be used on a 4431 router. Technically, I could install 3x NIM-8MFT-T1/E1 cards with the appropriate PVDMs but how many of them could I actually use? Surely the router would recognize a maximum number of configurable PRIs.

I have found this link about the PVDMs and am a little confused about the support of PVDMs on the 4431 platform.

PVDM4 Platform Availability and Performance

I've clicked on (and read) nearly every link here:

http://www.cisco.com/c/en/us/support/routers/4441-x-integrated-services-router-isr/model.html

I *thought* the solution might have been here:

http://www.cisco.com/c/en/us/support/docs/routers/4000-series-integrated-services-routers/118792-config-isr-00.html

Does anyone have a document of any sort in which Cisco tells you how many NIM cards you can expect to use for PRI circuits?

Hi there,

Hi there,

Check out the doc below, it shows that 720 channels (24x30 for E1 and 24x24 for PRI) would be the supported maximum on the 4431 as you thought;
