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.

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.
