Questions:
[1] Can I use oslec for echo cancellation? I'll have beefy hardware.
Is echo cancellation necessary?
Yes you can use oslec provided that either your distribution has a zaptel
package with the oslec patch (or you build the zaptel drivers + oslec
yourself)
Well without echo cancelation you will probably have a number of calls that
have either very bad sound quality or are simply annoying
With your set i.e 3-4 lines processing requirments are minimal so you should
not worry about that.We have been able to run oslec for 4 lines on a 266Mhz
(no its not Ghz) powerpc embedded board with very good results

Hello,
Please forgive me for i'm not an asterisk user yet. I've done as much
research as I can .. and have the following questions.
I'm setting up a new office and a home office and i'm shopping for hardware.
Office: 2 analog lines
Hardware: TDM412B (2 FXO, 1FXO)
Link: http://www.voipsupply.com/index.php?cPath=99_555_556
Cost: $303
Home: 1 analog line
Hardware: TDM421B (2 FXS, 1 FXO)
Link: http://www.voipsupply.com/product_info.php?products_id=3980
Cost: $300
[2] Can I get PCI express x1 cards for the same price?
I'm on budget, Any other cards (sangoma? rhino?) that might work well?
I'm sure these questions have been asked before.. 
Steve

If you only have one analogue line why not just get a simple x100p card?
When you use OSLEC with them they work great here in the UK. I bought my
card from a USA based eBay seller. Total cost for card and shipping was
about ?17.00

I would think you will always want to have EC. Whether you will need
oslec or not is another matter. If the standard MG2 sounds crap, try
oslec. MG2 couldn't deal with echo on my x100p. Oslec is pretty much
perfect.
I don't think you will need "beefy hardware" either. I have our Asterisk
server running on a Via CN700 (1Ghz) along with lots of other
applications. No troubles. Of course it is a home box and not heavily
used but hey - the mobo only draws about 7W!
If you want to know more about it see my sig below. There's a series of
articles about setting up and building a home server with Asterisk and
other bits and bobs.

There's a big difference between $300 and $34 for one analogue line on a
home phone.
Of course YMMV

If you use traditional PC hardware (ie with an available PCI slot) then
you can use the TDM 4xx card from Digium. I had a TDM400p and it worked
well enough, much better than the X101p.
If you choose embedded hardware (Soekris, Alix, WRAP, etc) then you may
not be able to add a PCI card. The external interffaces are necessary,
like the Linksys SPA-2000/3000 series. These also work fairly well.
They have the advantage of not requiring Zaptel.
Nothing about your installation suggests that a traditional PC would be
beneficial. In fact, "Beefy" would just me more power, heat & noise.
Someone recently told me that the Alix 3C systems are $150 complete
from www.mini-box.com. That would seem like a bargain, and ideal for
your circumstance.

If your budget is tight and you want a decent card (not an X100P) with
room to upgrade, then check out
http://www.openvox.com.cn/products.php?genre_id=25 or
http://store.getvoicecards.com/index.php?cPath=66 they are the
reference design that Digium used on previous cards and are very well
made. You can even use their FXO/FXS modules in a real Digium card
and visa versa.
The page I linked to includes the Octasic SoftEcho software.
Word has it that the guy responsible for these cards was a former
Digium employee back when Digium was only a few people (Mark Spencer's
right hand man) and he also developed the Tormenta III card for
Govarion. I have seen documents and some other things that back up
this information......

Martin,
I hope you don't mind me blowing your cover slightly. I did not state
your name but I have been recommending your products whenever
possible. The reason for posting your background info is to establish
credibility, but I should have probably asked you first.
Let me know if you want me to stop supplying personal details.
I hope hardware sales are going well.
Take it easy,
Steve |

That is a sore subject, as well. As best as I can tell, Martin left the
company with an agreement letting him pursue a business selling the X100P
(because Digium planned to stop selling that board, and there wouldn't be a
conflict), and because of a miswording of the agreement, it let him clone
Digium boards that he had worked on (even though they're not exclusively his
designs).
Note that purchasing Digium boards helps pay for full time Asterisk
development, and purchasing clone boards does not pay for even a part-time
Asterisk developer.

Those agreements are not enforceable beyond a certain amount of time.
I think five years has been struck down by many courts due to the
nature of IT. I think one or two years is generally upheld in states
that favor such agreements. Overly broad non-competes are thrown out
of court left and right, even if one part of the agreement is
questionable, other courts will line item sections of agreements that
are not generally enforceable, while keeping the rest of the agreement
intact.
Miswording in a legal document is bad. I guess Digium learned a
lesson on that one. As I said before, some judges will throw out
entire agreements based on a single mistake.
Besides, I have a feeling that he was not treated well by Digium or
Govarion (this is just my opinion and have nothing to back it up)
except some very interesting stories.
The bottom line is, the government does not really want to inhibit
your ability to earn a living but they weigh that with the harm it may
cause to the company the individual has made an agreement with.
I am surprised there was some sort of agreement about the X100P since
it was not a direct Digium product but a (possibly slightly) modified
modem with Opensource drivers.
Anyways, getting back to you point about support Digium, others are
suggesting purchasing the X100P (modems) with special opensource
drivers. I am all for supporting Digium but more interested in
support Asterisk by giving it a good reputation and exposing it to
large companies including CSC, The US State Dept, and Federal Data
Corp (among others I cannot speak of)
Bottom line, the guy has a tight budget. I have a feeling an X100P
will leave a bad taste in his mouth. I am just pointing him in a
direction that will help him. My allegiances are not to Digium
(although I support them myself) but to the community and especially
the newbies.
This is the "Asterisk Users" list, not the "Support Digium" list. I
thought vendor neutrality was totally acceptable here.

BTW, I am all for having payed Asterisk Developers but I think it is
needless to say that Asterisk would immediately see many more free
Devs or be forked (as it has for other reasons such as the dual
licensing) if Digium could not continue to provide in-house
development.
I know that sounds harsh but it is the truth.

Interesting results in Google for TDM400P TigerJet reference design.
http://www.google.com/search?hl=en&safe=off&client=firefox-a&rls=org.mozilla:en-US:official&hs=h9P&pwst=1&sa=X&oi=spell&resnum=1&ct=result&cd=1&q=Tigerjet+Reference+design+tdm400p&spell=1
Other keywords turn up much more similar results that seem to confirm
that the reference design from TigerJet was used.
As with anything on the internet, take it with a grain of salt but it
does have enough hits to raise questions.

No, it doesn't. It simply is an oft-repeated falsehood. GO to the TigerJet
page, LOOK at the reference designs. They do not hide a single reference
design from the web, and NONE of them are the TDM400P design.
If it was a reference design, please show the world the reference design

I guess you have reading comprehension issues. I said "take it with a
grain of salt" as well as "seems to confirm". Both are very benign
and offer two sides of the story. I think your personal feelings are
overpowering your ability to comprehend and reason.
Anyways, maybe the entire reference design is not there but just
connect the 2-3 reference designs and you're there. Tigerjet provides
the reference design of using the PCI chipset + they provide the
reference design of the X100P (pretty much) and going from X100P to
PCI card with one FXS module is not that hard (just different Silabs
chip) and then multiplying it only needs a small CPLD chip.
Not much brain power to come up with that.
BTW, rumor has it that Mark Spencer did not have contracts for
employees with the exception of salary, back in the old days. Maybe
you can ask him or check Martin's employee file.

Two sides, as in, the truth, and false rumors.

Correct.

No, they do not. They do not provide a single implementation of
an FXO interface on their site, only FXS.
| Quote: | and going from X100P to
PCI card with one FXS module is not that hard (just different Silabs

They are completely different designs.
| Quote: | Not much brain power to come up with that.
|
I'm not sure how many boards you've designed in your life, but given my
awareness of the design process of both modules of the TDM400P, I know that
building one does NOT mean that engineering the other is easy. Some hardware
engineers could probably confirm this, if they are so inclined.

I might indeed be able to ask Mark, if he has the time, but I certainly cannot
delve into a past employee's file, as there are important privacy issues to
be considered. I would be very much surprised if HR let me look, even if I
considered asking.

Thank you all so much for the information. As much as I like to purchase
Digium hardware, I'm on a budget, I like the OpenVox PCIe A400E22 (2
FXO/2FXS) card which has enough room for expansion.
http://www.openvox.com.cn/products_detail.php?genre_id=38&id=109
I wil be using a Intel C2D E7200 with Micro-ATX M/B in a showbox case. The
M/B has 1 PCIe 16x, 1 PCIe 1x and 2 PCI slots. The PCI slots will be used by
TV tuners for MythTV.
I could not find any US distributors for Openvox cards and I don't want to
pay international shipping.
Any ideas?
Thanks,
Steve

http://store.getvoicecards.com/contact_us.php is the same card and is
available in the US.
Thanks,

Other keywords turn up much more similar results that seem to confirm
that the reference design from TigerJet was used.
As with anything on the internet, take it with a grain of salt but it
does have enough hits to raise questions.

No, it doesn't. It simply is an oft-repeated falsehood. GO to the
TigerJet page, LOOK at the reference designs. They do not hide a single
reference design from the web, and NONE of them are the TDM400P design.
If it was a reference design, please show the world the reference design
from TigerJet. There simply isn't one, and repeating it does not make
it so.

Two sides, as in, the truth, and false rumors.

Pot. Kettle. Black.

connect the 2-3 reference designs and you're there.

I think you underestimate the field of hardware engineering.
| Quote: | Tigerjet provides
the reference design of using the PCI chipset
|
Correct.
| Quote: | + they provide the
reference design of the X100P (pretty much)
|
No, they do not. They do not provide a single implementation of
an FXO interface on their site, only FXS.
| Quote: | and going from X100P to
PCI card with one FXS module is not that hard (just different Silabs
chip) and then multiplying it only needs a small CPLD chip.
|
They are completely different designs.
| Quote: | Not much brain power to come up with that.
|
I'm not sure how many boards you've designed in your life, but given my
awareness of the design process of both modules of the TDM400P, I know that
building one does NOT mean that engineering the other is easy. Some hardware
engineers could probably confirm this, if they are so inclined.

employees with the exception of salary, back in the old days. Maybe
you can ask him or check Martin's employee file.

I might indeed be able to ask Mark, if he has the time, but I certainly cannot
delve into a past employee's file, as there are important privacy issues to
be considered. I would be very much surprised if HR let me look, even if I
considered asking.

So the question begs, how come there was never any effort to patent the card?
I do not design cards but I do know many people who do. The TDM400P
was a piece of junk and Digium very often blamed the motherboard for
the issues. This was until Sangoma came on the scene and raised the
bar. With ~15 employees no less. People jumped ship from Digium in
droves (similar to lemmings) to go to Sangoma since the IRQ issues
were null. Competition is the only reason we have cards that are up
to par.
I think you are new to Digium but I have quite a bit of back ground
info dating back to Linux Support Services and the fact that the .3
version of Asterisk only supported Adtran (go figure...)
I can certainly post more "dirt" from Mark's previous right hand man
if you wish to continue this argument.
The truth will set you free. Don't buy Digium propaganda, look at the facts.
Why would Mark build a PBX from scratch for his start-up when a
Toshiba, 3Com, or NEC could be had for a few hundred dollars (not to
mention Mark's close ties with Adtran including funding. Things just
don't add up, let's use our brains and not by the zeitgeist put out by
Digium.
Thanks,
Steve Totaro |
