Interfacing ASG to T1 service?

CJL
Since the ASG lacks a T1 port, what are people doing to interface to T1 IP services?

I know I can route a small subnet and use a T1 router with basically all services disabled and the ASG on one of those addresses but that seems like overkill.

I would really like to be able to configure just a /30 interface subnet (one address for each end) and be able to use the Astaro's NAT/PAT to provide access to the firewalled devices.

Curious what solutions others have come up with.

    You will need some form of CSU/DSU to handle the serial to Ethernet conversion, most customers do use a router to handle the conversion.

    Right.  The CSU/DSU provides conversion of T1 service to serial (usually v.35) and the router gives me serial to ethernet routing.  Sometimes the CSU/DSU is internal to the router.

    I'm wondering if there's a different approach that might transparently "bridge" the T1 to the ASG allowing me to avoid routing two networks to the customer.  Admittedly, this is not a function of the ASG.  Just wondering what others have done.

    Something small and relatively inexpensive (to, say, a Cisco 1800 with T1 WIC) that can do this would be great.

    In a past life, not an official Astaro answer, and whatever other disclaimers are appropriate...

    I have used a wide variety of Cisco 25/26/35/36** routers over the years, but HP's ProCurves have become a viable option and a much better value.  The fact that ProCurves include lifetime support means you never have to deal with SmartNet.

    Check out the 3COM units too (good bang for the buck)... we too use a lot of Cisco edge routers with T1 WICs... there's really not a need to spend the extra money on a separate CSU/DSU.  Most ISPs, when provided Voice and Data integrated services over a single T1, install their own CSU/DSU (Also called an IAD, Integrated Access Device, at least by the service providers I deal with) complete with an ethernet port that you can connect directly to your Astaro.
