I've ordered four new T1s from MCI for 6 Mbps Internet service. I plan to use an existing 3640 router. Is there a quad serial WIC card available?
If not, I guess I'll need an NM-4T. Can someone recommend an economical multi-port CSU/DSU for this application?
Thanks.
There are dual Serial WIC's but not quad. They go for about $55 on eBay these days.
So, if you already have an NM-2FE-2W with two open WIC slots, you only need two WIC-2T's (and supporting cables)

Do you already have CSU/DSUs? If no, you can get two VWIC-2MFT-T1 cards, which include the CSU/DSU.

All three of you guys recommended a two port WIC, which means I'd need two for my 4 T1s. I've only got two available slots in my router and thought that preserving a spare was pretty important. Am I making too big a deal out of this?
Yes.
But you can easily put in more WIC slots. You aren't limited to two WIC slots. External devices can go bad. Cabling can go bad. An integrated unit is better. Cisco doesn't make a 4-T1 integrated CSU/DSU card.
You were thiking of putting an NM-4T, so you must have a free NM slot. Another NM-2W or NM-2FE-2W can go in there if you need 2 more WIC slots later on.
