Brian,
In order to avoid getting caught up in the terminology (and risk that
someone at your telco is using it improperly), I would state emphatically
that you plan to terminate the service with a non-ISDN, relgular ol' CSU.
Make certain that they know that and you should be fine.

You would have to get a different CSU for your router.

OK this answered my question. If
else? Initially its just my site and the ISP. Thanks for your
post, these are really helpful.

This is not quite right. Yes

T-1 is the layer 1 standard. ISDN PRI uses T-1 for layer 1
connectivity.
Therefore, whenever you say ISDN PRI, you are referring to T-1.
However,
not all T-1's are ISDN PRI.
The "other" T-1 is referred to as CAS, channel associated signaling
Nope! T1 CAS can be used for either data or voice. The same for ISDN (PRI)
T1.

John,
You make a good point that channelized T-1s are all but unheard of.
However, the term "clear channel" doesn't mean unchannelized. It means that
the DS0s are the full 64 kbps, as opposed to the older bit-robbed 56 kbps DS0.

If you plan on terminating only analog calls then channelized T1 is
fine and generally cheaper. Want ISDN, get a PRI.

This is not quite right. Yes, ISDN PRI is physically a channelized T-1.
In this case you have 23 data bearing channels and one signalling
channel.
For data, you can order a channelized T-1 if you need to. This gives
you 24 channels available for data, but they are entirely separate
channels.
I'm afraid that isn't so. You can order channelized and non-channelized
T-1s to do whatever you want with. So there is a big difference between an
ISDN PRI (and all of the associate ISDN stuff - D channel, etc) and a
run-of-the-mill T-1 (and its total lack thereof). Placing a CSU/DSU on the
end
.
Normally when people refer to just "T1", they mean T1 CAS.

PRI gives you 23 channels of 64K each.. Which is equivalent to a T1 -
1.5Mb
For a VPDN, users could dial into a PRI

Is there any drawbacks to getting a T1 PRI vs. a regular T1 (I think
that's called channelized). I am not sure of the drawbacks of using PRI,
with VPN, and things like that work fine over PRI? Is PRI just like a
regular T1? The reason I am asking is I tried to get a T1 and I was told
I could only
