Will a 3845 router be able to operate effectively with 4 T3 modules?

This would be a temporary solution for about a week. The router will only serve as a pass through to the core site, no internal LAN routing.

The following documentation states that a maximum of 2 NM-1T3 are supported in a 3845.

Yes, I know that 2 are supported as stated in the documentation. But can it function temporarily with 4? I've seen a 3725 fucnction for a long time with 2 T3 modules and the documentation says it only supports 1.

According to the following Miercom report, the 3845 can handle up to 1.1Gbps of aggregated traffic. So from a sheer horse power viewpoint, this should be plenty to support 4 T3. Try getting the 4 NM-1T3 in the chassis and see if it sees them correctly.
