dual router back to back serial connection (2501 <-> 2620)

Thanks in advance.

Is it possible to run a back to back serial connection between a 2501
and 2620?

If so, what cabling would I require?

If not, is there an alternative configuration for the topology below,
or should I pickup another 2620?

Purpose: simulate a WAN connection between the two routers.

Reason: one router would be dhcp client for cable modem, WAN serial to
second router WAN serial, which acts as gateway for LAN.

What serial module does the 2620 have ?

I am certain the 2620 serial is WIC-1T, the 2501 has DB60 sync.

Many Wic-1T have DB60 plugs. If you have this, any of the DB60 to DB60
cables sold on Ebay ahould work.

If you have a WIC-1T with a Smart Serial connector, DB60 to Smart Serial
cables are also available on Ebay. There are two different types. The DCE is
the DB60 plug on one, the Smart Serial is the DCE on the other.

All WIC-1T have the DB60's, WIC-2T are the smart serials.

    I thought so too. All of the WIC-1T I have seen were DB-60 until
yesterday,  when I saw this on Ebay:
            Cisco WIC-1T w/ Smart Serial Connector like WIC-2T New     Item
number: 250032755842

Check it out. It looks genuine. If your monitor is bright enough, you can
make out the silk screen " WIC-1T ".
If it is not genuine, what is it ?

I did a little research on these. Yes, there definitely are WIC-1T with
Smart Socket interfaces. I have seen a couple on Ebay. Both were shipped in
uBR914 cable modem routers. This router,  I was told, was a totally
non-functioning piece of junk. The only mention of it at the Cisco web site
is the EOL and recall notice. So I guess this is why there are not a lot of
these budget versions of the WIC-2T around.

very bizzare! The 914 was EOL/EOS in 2001. Smart serials weren't even out
then. Can't find any mention of Cisco's site regarding anything with a 1
port smart connector! Collectors item? LOL

You can't find anything on Cisco other than the recall. The board is
currently on sale, as is the router. Comment on the pictures.

When did Smart Serial begin ?  I am not sure, but here is a 2600 data sheet
from 1998. It mentions the WIC-2T.
