Hello All, I could use a recommendation if anyone has a moment. I have the T100P but I have not gotten my service yet. I want to have at least 12 lines of digital voice with DID. Should I just seek out a PRI ISDN provider or is there something else I should look for? I want to keep cost as low as possible. Also, I want to own my own router for the phones since it is always a hassle to get anything fixed from the tele-company. What is a good and cheap router (Cisco maybe) that I would use to interface to the T100P? I plan to integrate my system to use our old analog lines for fax so I will have questions on that later too. Thanks everyone! Wiley -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20050105/26936166/attachment.htm

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.> What is a good and cheap router (Cisco maybe) that I would use to > interface to the T100P?

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. -- Steven Critchfield <critch@basesys.com>
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?

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.

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.> Finally, let me say thank you.

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.> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com > [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Steven > Critchfield > Sent: Wednesday, January 05, 2005 1:28 AM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: Re: [Asterisk-Users] Digium T100P T1 Card > > On Wed, 2005-01-05 at 01:01 -0700, Wiley Siler wrote:> 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 theT100P.> 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 FXSports.> I used to do something similar to that with a Zhone channel bank > before our company fully trusted asterisk.-- Steven Critchfield <critch@basesys.com> _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Peter, I also made it a point to voice my appreciation and recognize the fact that Stephen is major contributor here. I also acknowledged his generous explanations. I have also since replied to his reply and thanked him again as well. A consultant so I can get a T1 PRI on my wall and use it with my Asterisk box? LMAO. That is the dumbest thing I have ever heard. I need a consultant so I can get a T1 with PRI? Please. I am just trying to better understand how the Digium PRI card works and how it interconnects to the ISP. I checked the Wiki and I check Digium. Neither one said "install PRI card and no other router is needed". Or rather, what I did find was the reference that said that your * box will act as a router with the PRI card. Then it clicked and I got it. Having never had a PRI T1, I did not know it would be unlike my current T1 which has an AdTran to break out my voice from the data. So asking how to connect the Digium card seemed natural for this discussion. Again, thank you for you contribution to the discussion. If my previous response was offensive to anyone, especially Stephen, I apologize. If it is not clear, I view the gurus here as generous contributors. I just generally don't like criticism with my answers.

He started out by saying that he found your email hard to read and the reasons why. He then stated that you have a lot to learn about T1/isdn pri which is probably true.

I mean, it is not like I am asking how to insert a PCI card or something. Maybe that is the price to pay but really I think it just is not usually needed. It would be so much easier to just not respond if what I have sent is so horrible. Sometimes I think that this response is just because so many questions are asked and people get tired of poor formatting and such. Regardless, my OWA was to blame for part of that. Speed typing was the other. Besides, asking how my T100P interconnects is hardly fishing for general telecom knowledge. The questions were specific to the hardware from Digium. That makes it pretty relevant I think. I am googling up other stuff mentioned by Stephen right now.

Hi folks, Until now I have used only SIP & IAX2 with success and understand them pretty well. The point is that someone has asked me to configure an * box for them, the problem is that they want to use H.323. I have already compiled and tested the chan_oh323 with asterisk and works. The problem is that the tests need a gatekeeper, my question is: Do I need always need a gatekeeper? Or my FXO H.323 gateway can register with * ? Thanks, Humberto Aicardi

Then you would use IPTables or whatever your version of the kernel is supporting to act as a firewall as routing itself will be mostly natural once you let the kernel know to forward packets from one interface to another. While it is possible that there may not be any need to reprovision with the ISP, it is possible it would need to be too. Check to see if the data portion is being sent as HDLC. If so you should be able to discuss with them just replacing the Adtran box with your asterisk box. Then you just need to make provisions for your fax machines to get access to a phone line either via a SIP to FXS device or maybe one of the TDM400 cards. -- Steven Critchfield <critch@basesys.com>
Good points all. Apologies and thanks again. I guess I am the master at leaving out pertinent information. We are locate in Phoenix AZ. I currently have a fully functional phone system built on * that uses Polycom IP 500s over SIP internally. Lines from the AdtTran are delivered via two TDM400P cards in my Aasterisk box. Both the box and the client phones sit behind my Cisco firewall. I am only servicing 12 extensions internally and a single fax machine. Growth is is expected to only increase to 20 SIP devices/users in the next 6-9 months. The goal is to get better line quality, have DIDs, and increase line count. How we get there only has to follow two parameters. It has to be cheap cuz the boss is... It has to work because the boss wants perfection for the lowest dollar... I am sure you can imagine. 8) That is a ton of options. Thanks!

Until something is said that is blatantly slap in the face nasty, don't assume that a comment is meant to berate. For my one comment about the amount of knowledge left to learn, you should have accepted it as a measuring stick commenting on the depth of knowledge required to get to where you wanted to be and the estimated amount you already possessed. So while it might have been a bit of criticism, I went ahead and was willing to lay out examples that matched your situation to help fill in the gaps. Consider that a sign I felt you were worth me spending my time on and your likely hood of understanding the information I was about to give you.> To further explain my siutation, I should give you some more > background on my setup.

It might be a good idea to look into what it costs to break the contract, get DSL installed and your voice lines as a fractional T1 or PRI. DSL is usually quite a bit more inexpensive than a fractional T1 but at the cost of a reduced priority if you have a line failure. A full data T1 in my area seems to run about $750 a month, but I can get a business class DSL 3meg for $85. As you can see, it wouldn't take long for the difference in service charges to add up to the cost of breaking the contract. You then can look at what it will cost to get a telco to drop a T1 into your office space. Last quote we where involved with was around $200 for the loop and then whatever service you wanted on it. So 12 lines would probably run around $500 or so. Compare that to your service now and see what you think.> 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.

But working within your constraints now, lets look at what can be done and what needs to be available as a feature. Obviously you need some analog FXS ports for your fax machines. With only 1 T1 span available, you probably need to follow the suggestion I made before about passing the T1 through a channel bank and using the spare channels to signal back to the FXS or FXO ports in the channel bank. Remember that your T1 interface can have 24 channels and if you only have 12 phone lines being passed from one external to the channel bank interface(PSTN side) to another external to the channel bank interface(T100P side), you can use the remaining 12 channels in the T100P side to signal back to analog ports on the channel bank. Granted this doesn't let you use PRI. That is why I suggested you look at E&M wink. You still get your DIDs but they can be passed from one machine to the next without much trouble. What do you plan to use for phones in your office? SIP or analog? If analog, you will definately want another T100P card so you can bring the T1 line in directly to the first T100P card and then use the second to connect all 24 channels of the second T100P card to a channel bank. Or how about, you explain a bit more about where you want to go instead of where you are at so the end point can be planned then you can decide how to get there.> I will have to google up ILEC and CLEC for more info b/c that is new > to me as well.<Single quote is me(Steven) from the previous message>> come from a ILEC(former baby bell) or a CLEC(competes with ILEC). YourILEC is the Incumbent Local Exchange Carrier. Or what many used to call the Baby Bells, what was left after the break up of "Ma" Bell. They are the one you probably most likely think of in your area as the big provider. Here in the south east, it is BellSouth, Elsewhere you have Pac-Bell(I think this has changed) and SBC. CLEC is the Competing Local Exchange Carrier. They often times lease phone lines from the ILEC at reduced rates and then provide lower cost or different services on the same wires. These are all the smaller companies you see selling service. -- Steven Critchfield <critch@basesys.com> _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Getting someone who knows the field is really a good idea for almost anything more complex than a single analoge connection. If you do know the stuff yourself, great. Otherwise your time will have to be pretty cheap to compensate for the time it takes to know enough to build an isdn pbx with voip. Peter

Well, I wont say my time is cheap or that I know everything about the T1s. However, I did manage to build my PBX on *, implement Polycom IP 500 phones pulling configs from the network, and script my own extensions all with an initially minimal understanding of Linux. I have dealt with problems as they arose, sought out solutions on the wiki and elsewhere, learned more about Linux and I am very comfortable with the system now. Telecom is complex but that does not mean that only a contractor can get it done. If I had money to pay a contractor, I would probably have had money to buy a boxed PBX in the first place. Cost effective has always been the greatest selling point to me regarding my * PBX. Just enjoying the challenge and learning new things has been good too. I have no question that I am capable of implementing this. How long it will take and how hard are of course different questions. That I have only myself as a resource is not. After reading the wiki on setting up the PRI it does not look that complicated to me. The recompile is the only portion that looks time consuming. That may prove wrong or right. Regardless, I will be going the course alone... And that's OK. 8) Thanks, Wiley -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Peter Svensson Sent: Wednesday, January 05, 2005 4:27 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] Digium T100P T1 Card On Wed, 5 Jan 2005, Wiley Siler wrote:> A consultant so I can get a T1 PRI on my wall and use it with my > Asterisk box?
