Ray,

When I asked this question from the group they ignored it. I don't want you
to suffer the same fate. I have a couple of comments for you.

1. While the TC is a good unit it suffers in its ability to dial out the
ISDN ports. This is critical in usage sensitive areas (like Bellsouth),
where the BRI is metered and the PRI is not.

2. Depending on the number of PRIs/modems you have, the choice may be
simplified. I prefer the Cisco solution since I know I can get a DC power
supply (we're CLECs, LD providers, etc.) and -48VDC is very attractive to
me. The AS5200 will handle 2 PRIs and 48 modems, and can be stacked. If
you are going to have to stack 3 or more, I would recommend you get an
AS5300 first (4 PRIs/96 modems) since it has a very nice RISC processor and
can handle added units with ease. You can then add 5200s to your hearts
content.

3. Buy the units maxxed out, even if you don't need all the capabilities
initially. It really is less costly to buy them fully configured up front.

4. The cost per port on the 5300 will be slightly more than the 5200, but I
think it is worth it for the first unit.

If you have any other questions, I'll try to help.
