need a router with non integrated DSU/CSU to connect to a Kentrox DataSmart DSU/CSU via  a 25 pin  serial interface

My Client is procuring a T1 line, The telco guy is using a Kentrox Datasmart T1 Dual-port DSU/CSU and is going  to appropriate  x channels for voice and x channels for data.  The Kentrox DSU/CSU has a 25pin RS232 serial interface that supports v.35  and allows you to connect a router to it.  I have searched endlessly to find a router with a non-integrated CSU/DSU  with very little luck I did find a Cisco 1814 but the price is over the top for the client.

Does anyone know of a router that can connect to the Kentrox via a serial interface.

The ProCurve 7202dl (J8752A) router supports V.35, it's about $1300 AUD.

Maybe 3com have something..?

I don't think you'll be able to find anything cheaper than that, and if you do, it's probably not going to work that well... I'd stick with either Cisco or HP.

You don't need the internal CSU/DSU, you just need a serial interface and V.35 cable
Cisco 1841 with WIC-1T and CAB-V35MT cable

The answer by lrmoore is correct and I just wanted to point out that a lot of the expense of a Cisco router is the interface cards (e.g. the WIC-1DSU-T1 lists for about $1k USD).
This may not be the answer you want to hear, but an old Cisco router (2501) is exactly what fits the need best.  While it is not still supported, I have yet to have one die on me and it comes with the required serial port built-in you would need only the serial v.35 cable.
However, if it must be new, I concur that the 1841 with the WIC-1T is the entry level Cisco device.
If you are not married to a Cisco solution, RAD makes a product called the WebRANger-II that would work and is less expensive in my experience.
