John,
Depending on your bandwidth needs you might want to consider ISDN. My
company uses BRI ISDN to back up each frame relay connection. Fairly
inexpensive and with a few lines in your router config, can automatically
come up when the frame relay goes down. I would recommend a 800 series
router for relatively low traffic sites (I use them for small offices of up
to 30 people) to back up a 2600 running the frame connection.
All in all, it is a relatively cheap and functional solution.
If you share some more info like your bandwidth requirements, etc. I am sure
others will chime in with other recommendations.

Subject: High availability design with FR, how?
Hi All...
I have a mandate from on high that all of our routers now have HSRP support.
Not a problem on the LAN side, and I have worked out the point to point line
issues by using channelized lines and creating two serial lines. But the
frame relay (FR) is killing me!
So far the only solution seems to be with the telco providing a second FR
host line that in the event of failure we call a computer at their end and
dial a few numbers and the PVCs are moved to the secondary FR host line.
Needless to say doesn't sound too hot to me, as it requires that everything
work just right to get a reasonable failover, and this may not be in a
timely manner.
Anyone have any thoughts?
