Hi Rayo,<br><br>
We are using a Cisco 1602R router. I don't believe they are
available as new product from Cisco anymore, but there are plenty still
available.<br><br>
1) low power -- <font color="#0000FF">325ma at 12V, or around 4W<br>
</font>2) field hardened -- <font color="#0000FF">well, sort of.
We've had some failures over time, but surprisingly few given the fact
that they are not made to be is an unsealed vault in the middle of
nowhere.<br>
</font>3) uses 110V AC or 12V DC power --
<font color="#0000FF">either. Like Kyle says, the plug is of an
unknown type. We just cut the brick off and put spade lugs on for
12V solar operation. Now that I look at it, it kind of looks like
an "S-video" plug, but that would be hard to believe.<br>
</font>4) capable of SLIP and Ethernet --
<font color="#0000FF">definitely Ethernet, but I can't say anything about
SLIP.<br>
</font>5) easy to setup, use standard templates possibly browser-based --
<font color="#0000FF">difficult to set up, although we have written up a
cheat sheet on all the steps you need to follow to do so.<br>
</font>6) remotely monitored via SNMP -- <font color="#0000FF">can't
say<br>
</font>7) reasonably priced or available as used --
<font color="#0000FF">Last time we purchased them for only $50/ea from a
used outlet in Santa Barbara called Network Hardware Resale. There
are other vendors out there too.<br><br>
</font>For the SLIP and SNMP questions, you might try Will Kohler in our
office. He might know. There is room for an extra WIC card
for expansion if necessary.<br><br>

We are looking at replacing some of the older Motorola FRAD's we use
with<br>
something that is easier to configure, deploy and remotely monitor in
the<br>
field. Our current setup consists of Motorola Vanguard 300 and 320
models.<br>
We configure these in both SLIP as well as Ethernet (RJ45) mode.<br><br>
Our main data receiving points at Caltech are all Cisco routers so
we<br>
looked at the Cisco 1720 routers with CSU/DSU cards. The problems
there<br>
are the voltage and current draw. These units require + and - 12V and
5<br>
Volts. And the current draw is pretty high(almost 15-20 Watts of
power).<br>
In places that the station is backed up on a battery, using an inverter
we<br>
would get data for only a few hours after a power failure.<br><br>
I am looking for alternate solutions or suggestions from people that
use<br>
CSU/DSU FRADS with some or most of the following features:<br><br>
1) low power<br>
2) field hardened<br>
3) uses 110V AC or 12V DC power<br>
4) capable of SLIP and Ethernet<br>
5) easy to setup, use standard templates possibly browser-based<br>
configuration<br>
6) remotely monitored via SNMP<br>
7) reasonably priced or available as used<br><br>
Thanks in advance,<br>
cheers,<br>
