How many E1 (VWIC-MFT) ports I can install on Cisco 3640 router ?

I have installed 3 VWIC-2MFT cards, i,e, with 6 ports but I can see only 4 ports !!

Some notes:

The 3600 NM-1E2W, NM-1E1R2W, and

NM-2E2W support one serial channel

group per WIC slot, thus the

VWIC-2MFT-E1 is not supported.

The NM-1FE2W, NM-1FE1R2W, NM-2FE2W,

and NM-2W support two serial

channel groups per WIC slot.

Therefore the VWIC-2MFT-E1 is

supported.

You should see some messages on the

console port when you boot the system

up, indicating what problems there

may be.
