Word of warning: back in our Rhythms reselling days (remember the good ol'
days ;-), we turned up one customer that was literally across the street
from the CO -- maybe a 400' loop tops. The automated provisioning system
Rhythms used kept reporting an 'open' due to the short loop even though
there was nothing wrong with it. The DSLAM equipment didn't believe any
customer could be that close, and we had a lot of trouble getting the
circuit turned up.

Sounds like something a 2620 could do. You can get an 8 port RS232 serial
NM for it, DC power, and a ethernet switch module. I'm not sure if you can
use the serial module and ethernet switch module at the same time without
moving up to something with more NM slots like a 36xx. I can't remember if
there is an 8 port serial WIC card or only an NM available, and the 2620
has 2 WIC slots but only 1 NM slot.
You can get the 26xx series used cheaply, and I frequently see DC power
supplies for them for about $10-20 on Ebay -- and those are new.

Better solution: add another fiber entrance to your colo so that your
SONET gear can heal your ring(s) in the event of a fiber cut. This way you
don't need out of band (as much :-).
