The following is just suggestions. I am not a Digium reseller and I will
only benefit from the following suggestions from by helping Digium and
by putting some new ideas in others minds.

Okay so your option is to choose an additional $500 card or possibly an
additional $1500 card. I can say the extra $1000 is no longer small
change, but I would still suggest it as a better option for the
following set of reasons.

1. With the spare card sitting in an antistatic bag, you could partially
recover from catastrophic failure relatively quickly. You are only a
small machine install configure away from getting your original single
span back up and running.

2. Development/testing environment. With a 4 span card in your primary
gateway machine, you can use 1 for your current usage, 1 for your fax
server, and a final span to cross connect to your backup system
installed with your legacy T100P card. Makes it much less dangerous to
test new CVS checkouts when it isn't the primary machine that helps pay
the bills.

Number 2 also builds on number 1 as it wouldn't be that difficult to put
a copy of the deployed code on your primary machine on the testing
machine and keep current copies of the dialplan/configs too. That would
lower your response time to a failure of any nature. 

Of course when I started te response, I thought I had a few more ideas
to share, but they seem to have escaped me now.
