Re: Connecting satellite locations via the Internet

Lurton,

Not to refute your decision, just tossing in my 2 cents....

Here in the Pacific NW, a 56k frame only guarantees 28.8
Frame installation is $1,000 at each end. Basic 2 channel, with a POTS,
ISDN is $125 install and, well it 2 channels at 64k, period.  The POTS
can work as a single FAX/Voice line.  The per month charge is
comparable.

This may be symptomatic of using a frame relay service.  ISDN has
consistent throughput.  How much per month does Lucent charge to "watch"
your line/their service?

The ISDN/POTS would provide a dialup backup at no additional cost. 
Personally, the POTS that comes with ISDN is, at best 9.6k and best
suited for fax/voice.  Just about any and all ISP's offer 56k dialup for
$19.95/month. Now that's cheap insurance.

Alternative to what? VPN are as tappable as any communication line. 
Locks keep honest people honest. If they want in, they'll get in. Get
over it.

Now that's a no brainer.  Your internal IP address is always hidden from
public view under any router/gateway.  This is not a plus provided
exclusively by your choice. Sorry, don't mean to be harsh, but this is a
given.

Sure you can prioritize, but what about the 20 hops in between?

You just gave me 50 more reasons to stay awake! :-)
