[Asterisk-Users] TDMoE question
Greetings ! I am looking into the TDMoE functionality of the Zapata drivers and * and i am kind of confused. Lets say i have 2 linux boxes, one has * running but no fxs/fxo hardware the other has a card (for example an x100p) but does not have * installed. If i just want to use the card (no * reduduncy etc) from the machine that runs *, do i need to have * running on both boxes for this to work ? or loading the appropriate drivers to the second machine will be saficient ? The examples i have seen mention zapata.conf entries which make me think that * should be running on both machines, but i am not sure if this applies in my case. Any ideas, thoughts, links etc are more than welcome regards Stelios S.

I am really a newbie though, so don't take my word as gospel.

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 !

[Asterisk-Users] TDMoE question
I am asked to consider deploying asterisk servers as soft-switches on a large scale, but wanted to preserve TDM properties of a call, especially for modem applications which some of the end users may want. I was thinking TDMoE may work well for this, at least on the surafce but had specific questions regarding modem data on the call. As most of you are aware a TDM network virtually guarantees that the data that enters the network comes out at the same cadence that it went in. Modems like this near exact timing. IP networks have no such guarantee so modems tend to not want to work well when VoIP protocols are used. Compression methods (codecs) used in VoIP can also distort the data for a modem call, as such they are undesirable. The usage that I am considering would be to have soft switches placed in stragetic locations throughout a large geographic area but be able to provide service to customers, which can include modem usage (think large phone company selling arbitrary phone lines to be used however the customer sees fit). As such I need modems to be able to work over this network. I had considered linking all the remote sites together via TDMoE (private network primarily using dark fiber). Does TDMoE provide effectively the same capacity to preserve modem data (upto and including 56k speeds) as a T1 would? Or would I need to actually transmit voice channels on T1/DS3/whatever framed circuits using the Zap interface? Has anyone tried TDMoE on longer runs, or at all with modem data? -- Trixter http://www.0xdecafbad.com Bret McDanel UK +44 870 340 4605 Germany +49 801 777 555 3402 US +1 360 207 0479 or +1 516 687 5200 FreeWorldDialup: 635378 signature.asc Description: This is a digitally signed message part ___ --Bandwidth and Colocation sponsored by Easynews.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

Re: [Asterisk-Users] TDMoE question
TDMoE is useless. I've tested it on newer intel P4 machines with 2.4 and 2.6 kernels. There is CPU peaks causing by TMDoE driver. If you want pass modem data, try IAX u/alaw codec. In my environment it works great (switched lan) trixter aka Bret McDanel wrote: On Wed, 2005-10-19 at 10:43 +0100, Appan KH wrote: You can use MPLS which takes care all the point you had mentioned. appan kh Not entirely, at least not as I understand MPLS.

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 Question
TDMoIP is nothing else like IAX2 with trunking, i would say. And a compression of 16/1 (payload bandwidth!) sounds like g723.1 to me. Just a Question.

I guess IAX2 is the *only* standard for TDMoIP, since the other trunked solutions are totally closed. :-) Regards, Steve ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
