How many active ISDN links could be supported by a 3640 in parallel?

We have a free 3640 with one Fast Ethernet/E1 module. We are planning to use this router in a disaster recovery concept. We want to upgrade the 3640 with 3 additional Dual E1/PRI modules. This will give seven E1/PRI ports (210 ISDN channels) in total.

Is the 3640 CPU capable to support 210 parallel PPP Links via ISDN?

Thanks a lot for your support.

I think you should concern if there is enough memeory to support these active ISDN links.
