How do you get more WICs unto a 3925 router?

Hello all,

We have a customer that has an old 3925 router with the following interfaces:

VIC3-4FXS/DID

2x  HWIC-4A/S

VWIC2-2MFT-T1/E1

2x VWIC2-2MFT-G703

NM-2FE2W-V2

For a totla of 6x WIC cards.  I know we can combine the 2x HWIC 4A/S into an HWIC-8A but it still leaves us with 5 WIC card in a 4 WIC chassis because of the end of sale on the NM-2FE2W-V2 which has been terminated.

This device is in a space and power restricted environment so the quick and expensive solution of getting 2x 3925E would not be feasible.

Is there another Cisco device that would support 5 WIC cards out there?

Thanks in advance.

The 3925 has 4 WIC slots and 2 SM slots - you can get a converter that turns SM into NM (SM-NM-ADPTR) and maybe even one that turns an SM into HWIC too I think (maybe SM-SLOT-DIVIDER, never used it myself) so I don't see the problem?

No, sm-slot-divider is a passive device that does not convert anything.

Regarding the OP question, the 3925 is not an old router. One can use 4-ports T1/E1 cards to increase density, there are also 8 -ports cards in form of network module.
