Re: [asterisk-users] TDMOE Timing
On Thu, Feb 19, 2009 at 5:00 PM, Dave Fullerton dfullertaster...@shorelinecontainer.com wrote: Hello all, I have two machines I'm connecting with TDMOE (dahdi dynamic spans) and I have a question about timing parameters. By my understanding one machine should be the source of the timing and the other a slave of that timing. So on machine A I have the following in system.conf: dynamic=eth,eth0/00:0C:29:55:89:7E,24,0 On machine B I have this is system.conf: dynamic=eth,eth0/00:18:8B:C7:F6:94,24,1 So machine A is the source of timing and B is slave to it. If both of these machines also have a digium (TDM400P in one and a TE110P in the other) card in them is this configuration still correct or should I use 0 for timing on both? The reason I ask is if I boot both machines fresh and I execute dahdi_cfg on machine A first and then machine B I either get a kernel oops (with 2.6.27.11) or complete freeze (with 2.6.23.17) on machine B pretty much without fail. If I do machine B first and then A everything works fine. I'm using dahdi_linux 2.1.0.4 on both. I know I can just use SIP or IAX or anything else to connect these two machines, but I'm using this as a learning experience to play with PRI setups. Thanks -Dave I cannot speak about DAHDI but I can tell you that the timing provided by the card is different than the timing of a PRI Span. I suspect that DAHDI has a bug in TDMoE because the spans should either not come up but Asterisk should run and the Kernel should not bomb out, at least I have never seen this with Zaptel. If nobody answers your question with a real answer, I suggest opening a bug report. -- Thanks, Steve Totaro +18887771888 (Toll Free) +12409381212 (Cell) ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] TDMoE with Telco
You can use TDMoE to get an E1 running but its really designed to replicate an E1 end to end Its a standard and there is equipment out there that does it, e.g. from RAD and a few others. I didn't have any joy using the Asterisk code to get it going but it should in theory work. Its completely different to Dundi The challenge it is a protocol and needs two boxes talking TDMoE at each end. Telco's do not have this as an option, or at least none do that I have found Cheers Duncan Michael Graves wrote: --Original Message Text--- *From:* Yacine Boukaba *Date:* Sun, 3 Aug 2008 18:54:08 +0100 Hello, is it possible with TDMoE to replace classic digital T1/E1 interfaces like digium and sangoma cards connected to a telco.

Thanks, Steve T My guess is what the original poster wants to know is if boxes like the redFone exist that allow you to set up your Asterisk box without having to directly plug in TDM cards like those from Digium and Sangoma. The short answer to this question is yes. There are a few solutions that run on TDMoE like the PhoneBridge redFone that plug into the T1/E1 from the telco on one end and connect to the Asterisk box via IP. Now about the MAC address, if you are talking about the MAC address of the TDMoE box that can easily be obtained but the MAC address of the telco's E1?? Not sure what you mean.

Re: [Asterisk-Users] TDMoE question
I asked about a similar application a few weeks back. This is sometimes referred to as campusing since you are basically going to make the two systems sharing their resources appear to be one system. From what I understand, you have to have both boxes running Asterisk. I am pretty sure that it's the Asterisk software, not the Zapata hardware, that does the actual sharing. :) Undrhil --- Asterisk Users Mailing List - Non-Commercial Discussion asterisk-users@lists.digium.com wrote: On Jun 25, 2006, at 1:55 AM, Stelios Koroneos wrote: Greetings !

RE: [Asterisk-Users] TDMoE
Well, I don't know what it is at the moment, I just know its a wireless T-1 that I'd migrate over to a different infrastructure. Actually, TDMoE can route and can go longer distances when you run it over Mikrotik and use their EoIP. Well, given that the fact that it runs over Ethernet instead of IP is its only issue.

RE: [Asterisk-Users] TDMoE - best signalling method?
I'm wondering if perhaps HDLC signalling is too intolerant of the occasional lost packet and whether one of the other signalling types would be better. I don't understand the other methods, so I would be grateful for any advice from those who have used TDMoE successfully. I would have thought that if you are losing occasional packets then that is the problem you should be focusing on... An unsaturated Ethernet connection should not lose any packets. I'm not sure that any TDM protocol is going to be particularly happy about lost packets. But please enlighten me if you know different!

Hi, I am having the same problem on 2 machines running suse 9.3 kernel 2.6.11.4-20a I was hoping that TDMoE would solve some problem that I am having using IAX2. As IAX2 takes the DTMF outof band the timing of the signal is not quite the same as the original and creates problems for other equipment.

Once you have this setup, your local users (users registered to same server) can call each by dialing local extension(1-999). Network users on the other hand need to know FULL dialing digits for a network user. For example a user from server A need to know FULL number ($SERVER CODE + LOCAL EXTENSION) for all other network users.

Re: [Asterisk-Users] TDMoE questions
Hi, Unless you have a very large configuration, the bandwidth of a 100Mbps ethernet will not be the issue. Theoretically you could have 10 E1's worth of TDMoE traffic on a single 100Mbps wire. I have sucessfully used EuroISDN with one 31 channel TDMoE (E1 is 32 64Kbps channels, where one is used for framming, so you have 31 useable channels). You could use Trunked IAX2 as well, the advantage is to avoid cross-coding, as TDMoE can only use uLaw/aLaw, while trunked IAX2 can use any useable Asterisk codec. However TDMoE to PRI/FXS/FXO connections are more efficient, as they can use zaptel bridging.

Re: [Asterisk-Users] TDMoE Question
It using DSP chips makes no difference, it can be done in software aswell... (in theory, if its open, and the algorithmic complexity is low) Secondly, I think just the Name explains the difference between TDMoE and TDMoIP... it's 2 different things... actually TDMoE offers very much overhead.. but it's meant for Ethernet... Lan... zaptel timing... low latency... TDMoIP... well... just some marketing buzz imho, and probably a proprietary protocol (I haven't even looked at the rad website) Regards Gary Carr wrote: Rad's TDMoIP uses DSP chips on each end of the link to compress the data.

Re: [Asterisk-Users] TDMoE hangs the machine
On Sun, 16 May 2004, Bruno Fontana waxed: I was trying to use TDMoE and I lasted with two problems. First of all I can't configure the dynamic span to use CAS signalling but documentation (by Mark) says that you can use any type of signalling (and this includes CAS I guess). Well just pick one that works I guess. You aren't limited to T1/E1 d-channel / b-channel ratios, either. Meaning you can create 200 b-channels and still have the signalling over only 1 d-channel. Not that you'll ever be able to push that much over the wire... My second problem is related that my Linux system crashes frequently due to ztdynamic and friends. I'm using a 2.4.26 version kernel and zaptel drivers 0.9.1 (Gentoo distro). I've looked for a solution or a clue in list archives but there was nothing. Any ideas?, someone who had a similar problem and have found a solution? I've found it unstable on high loads, in excess of 50 channels between smoking P4s, with or without any zaptel card drivers loaded. I would like to try blaming it on the switch, and possibly the NICs both facing the public network, but it was still 0 hops between boxes.

The benefit of IAX2 trunking is to cut down on your ethernet load and to make expanding easier. Not to mention IAX2 is much better tested than TDMoE. Can the IAX2 trunking do the equivalent of groups in Zaptel? What I'm needing to do is take a whole bunch of H.323 incoming calls and spread them out across many T1s (more than what would go into a single machine). Trunking does combining of control data and audio data into a single packet so there are fewer packets on the wire. Every TCP/IP packet has a minimum of 40 bytes of header data. If you can pack the packet full, or at least to the MTU, you save a few 40 byte sections here and there. As you approach your bandwidth limit, little things like this help. But, no, it doesn't do the same as groups I suppose I could do something like this in extensions.conf [incomingh323] exten = s,1,Dial(IAX2/foo:[EMAIL PROTECTED]) exten = s,102,Dial(IAX2/foo:[EMAIL PROTECTED]) exten = s,203,Dial(IAX2/foo:[EMAIL PROTECTED]) etc etc etc And then us Dial(Zap/g1) on each of the machines in the incomingiax context. This would work, and has the added benefit of doing fail over if you decide to take down a machine for maintenance. Then I just have to put a G.729 codec on each of the remote machines to handle the G.729 to TDM codecing. Yep, you would have to place the G.729 codecs on each of the endpoints to cover the amount of calls you are trying to pass. This may be a better solution for you as you can deploy a new machine per T1/E1 and fill it out with the new license as it is deployed. Digium has already commented about how painful it is to move or grow licenses afterwards. -- Steven Critchfield [EMAIL PROTECTED] ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
