[Asterisk-Users] Digium T100P T1 Card

[Wiley Siler]

Apologies if the format of the email was troublesome.  I am accessing my
email remotely via Outlook Web Access otherwise the format would have
been plain text.

So, I need to learn more about voice T1s?  Reeally?  That would be why I
am posting to the user group in the first place.  To learn more.  The
wiki says nothing about how PRI works because it is expected that
someone will know.  Well, I didn't.  Had to ask.  After cruising ebay
for 30 minutes looking at routers and reading the tech spec on the
T100P, I figured out the very same thing regarding the fact that no
router was needed.

Using my analog line for fax is not a matter of needs.  It is a matter
of using available lines that we will have for another 18 months because
that T1 is under a long contract.  The ISP company wants an arm and a
leg to upgrade the T1 from analog lines to digital so that is why I am
getting a separate voice T1 altogether.  That will leave these analog
lines unused so I may as well dedicate them to my fax system and keep
all the digitals for our voice.

Finally, let me say thank you.  Your info is exactly what I needed and I
truly appreciate it.  People who take time to help others should truly
be applauded.  I have seen scores of replies from you to others so I
know you are one of the best contributors here.  In fact, I usually read
yours first just because of the quality of your replies.

However, was there that much need for the criticism and arrogance in
your reply?  Wouldn't it just be esier not to reply at all than start
off with a complaint about my HTML formatting, go to a critique of how I
formatted my 4 sentence email (paragraph for 4 sentences?), and finish
up by pointing out that I don't know much about voice T1s?

Regards,
Wiley

It is preferable to not use HTML in email. Just because a font size
looks good on your monitor doesn't mean it is anywhere close to good
anywhere else. Your choosen font size ends up being 1/2 to maybe 2/3 the
size of standard text. In other words, had it not been for the slightly
interesting to me subject line, this would have been ignored as a user
to clueless to bother with.

Also learn about why paragraphs are good.

This shows you need to learn quite a bit more about phone service. There
is no need for a router on a telephony T1. You will either want to plug
a channelized T1 or PRI into the T100P directly. 

If you want some analog FXS ports, you could also go the route of an
ADIT 600 and plug the T1 into the ADIT and route your incoming 12
channels to the second port of the ADIT and then plug it into the T100P.
The benefit here is you will have 12 channels left over to signal back
from the T100P to the ADIT and have those channels routed to FXS ports.
I used to do something similar to that with a Zhone channel bank before
our company fully trusted asterisk.

You don't need analog lines for FAX. Follow the directions above for the
ADIT and you will be able to have analog ports to plug your fax machines
and route them out the T1.
