[Asterisk-Users] Digium T100P T1 Card

Wed Jan 5 10:23:34 MST 2005

LOL - Thanks for not getting mad about my email.  I just felt a little
stung for being uneducated about T1s but we have to learn somewhere!  
I completely understand your concerns and will try to comply as best as
I can.  
Again, thanks for being such a contributor to the this support system!! 

To further explain my siutation, I should give you some more background
on my setup.  My current setup has an AdTran 616 on the wall breaking
out my 6 analog lines and delivering my data to the office.  I have two
TDM400P cards receiving 6 analog lines which are used for both fax and
voice.  I have had numerous problems with this ISP and I just want to
get away as soon as possible.  Problem is, I have a contract that won't
expire for a while so I need to use these lines for something.  The ISP
wants a contract extension and some setious cash to do the upgrade.
Better to just seek alternate service.

I originally bought my T100P thinking I would get digital lines and all
the goodies involved.  Then budget constraints and an ISP that wants too
mcuh to convert me to Digital lead to a temporary solution.  I would use
the analog lines for a while longer.  Well, that has run its course and
I have to get to something more stable.  The PRI card looks pretty good
at this point.

So getting back to the T1 PRI issue (and I am playing catch up here), my
goal is to just deliver new service into this office over my T100P and
just dump nothing but fax out those old lines.  That way I can reserve
the digitals for our truly important calls and still reap the benefit of
having those old analog lines.

I will have to google up ILEC and CLEC for more info b/c that is new to
me as well.

Thanks again,
Wiley

Thats good as this message was very easy to read.

So lets back up and look at another option here. Don't bother that ISP
T1 at all. Look at your analog lines. Depending on the location you are
at, 12 lines will be delivered via a T1 and broke out to analog lines
via a channel bank of some sort. If so, then you are already a ways to
getting closer to what you want.

Either way, I wouldn't bother the ISP for voice. Your phone lines should
come from a ILEC(former baby bell) or a CLEC(competes with ILEC). Your
ISP will probably charge you so much more because they have to pay for
the phone lines and then put the lines onto your data T1 with
specialized equipment. Depending on where the other end of your T1 is,
that can be fairly expensive for them.

If your analog lines are delivered via a T1 interface and split with a
channel bank, your phone company will probably love to upgrade your
service. You will probably still want to pick up a channel bank, and if
you already have the T100P, you will want to get a channelized T1 to
take advantage of passing the T1 through the channel bank and coming
back for the FXS ports. 

On a channelized T1 you will want to talk about getting an E&M wink
lines and you can then have your DIDs.

No it isn't better to not reply. The complaint about HTML formatting is
important. Too many people don't understand what their formatting means
to other peoples readers. Maybe I am a bit sensitive about it as one of
our main clients has almost exclusively older ladies working for them
that have eye problems on track for the age. This has caused me to be
very aware of color choices and font sizes, or specifically choosing
relative sizes instead of hard choices. 

Consider that to be less of a complaint about you specifically and more
about the list in general. I placed in a response to you as it was
convenient and a fair portion of the list would see it. There are too
many people who compound the problem when there are several in a thread
with all kinds of alternating font sizes.
