asterisk users - Jan 2009 - ATA gateway with 2 ethernet interfaces

Hi,

I'm looking for an 8+ FXS ATA gateway (at least 8 ports but preferably at
most 24 ports) with 2 ethernet interfaces for network/switch redundancy.

So far I've only found the Grandstream GXW4008.

I've searched similar brands such as Linksys and higher-end brands such as
Quintum, but they all seem to have just one NIC. So, if the switch the ATA is
connected to fails then I'm out of business (at least until I replace the
switch but that's usually too long for a busy system).

The GXW4008 device is very useful for this scenario. It has 2 RJ45 ports (called
WAN and LAN) and I've set them up in two local subnets. Not only does the
ATA keep working without human intervention if one of the switches goes down but
if both switches are up it can load balance between the two (simply by using DNS
SRV with the same weights).

Unfortunately, Grandstream in general doesn't seem to be very reliable
although the latest GXW4008 firmware has proven to be quite stable in my case
(previous releases were buggy).

So I'm looking for alternatives to the GXW4008, even if it has to cost me
more money. Does anyone know of an 8+ FXS ATA brand/model with 2 ethernet
interfaces?

Thanks in advance.

I don't know of any ATA like that except the grandstream.

The service provider grade way to do this would probably be a Cisco (or 
similar) with a T1 interface and a channel bank to break the T1 into 24 
FXS ports.
