I don't think it's possible to get no signaling awareness with idle bandwidth awareness -- they don't mix. You either deterimine idle channels by watching the signaling (CAS or CCS) or you don't and pass everything unmolested, including idle channel data. I have not seen any information that says that it is possible to nail a t1 port to a TDMoE channel group on one end and vice versa so the signaling could be passed unmodified. Admission: I have never used TDMoE, but I understand telephony and the concept behind TDMoE and TDMoIP very well. TDMoE just takes the 1544000 bits per second (192 bits of 24 channel data + 1 bit of T1 frame data, send 8000 times per second) that a T1 produces and encapsulates it in raw ethernet frames. This is going from memory but I believe it takes the 24 timeslots (24 bytes) * 8 plus the 8 framing bits (+1 byte) and stuffs it into an ethernet frame and sends it on its way. That would certainly give you 1000pps as someone else mentioned. Again (from memory, and from looking at ztd-eth driver it looks to be right) there is no interpretation or manipulation of the signaling data done at all. The bits are passed as-is, which means if you're using the MCDN/NAPN/SL1 protocol between Norstar systems that it should all work. You have to decode the signaling, pass the media, and reproduce the signaling via asterisk at the remote end, correct? This means that id the signaling IS non-standard it is a no go. Only if you're trying to convert the T1 channel data to SIP or otherwise manipulate the bits. If you're only trying to get them to go from A to B then no, no interpretation is needed. If you're looking for a straight T1-ethernet bridge, TDMoE should do the trick for you. If your microwave link appears as an ethernet bridge (not an IP router) and it's robust enough and has enough excess (or the ability to prioritize ethernet frames based on MAC address) then this should work. If your microwave link is indeed routing you should still be able to get it to work if you do some fancy tunneling. Again, not impossible but you really need to do some testing. Not having done this specific implementation before I of course cannot make any guarantees. If it could be done, signaling matters none - the two connected devices would still understand each others foreign language (signaling) and the asterisk boxes would just provide a pure Nx64 data path. Exactly correct, and as I said several times in this email I am not aware of TDMoE caring one iota about what the bits represent. It merely passed them from A to B. It's certainly an interesting application. -A. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [Asterisk-Users] * point to point t1 solution?
Damon, I am not intimately familiar with what you are specifically trying to achieve, *BUT*, if the two Norstars are essentially just 'interconnected' via teh T1 to provide either an EM Wink "type" connection/private TDM bus between the two boxes so that extensions are 'bridged' between the two PABX's.. then *YES*.. Asterisk can do that. I have a setup at present of an Asterisk box that has 1 E1 PRI coming in from a telco, and 1 E1 PRI going TO an Ericsson BP250 system. The Asterisk box transparently passes incoming calls destined for the BP250 to the BP250, and all the BP250 users can 'direct-dial' so to speak Asterisk extensions and vice-versa. Since your original question is a tad ambigious to someone not entirely intimate with your setup, I could have missed the point entirely, as there is quite a few 'ways' to tie PABX's together and the reasoning can be very different (Could be for 'switched' extensions, could be for LCR setup, could be for VoiceMail integration, could be cause thats what the original installer just did...) Hope that helps you a little. I'd suggest looking at "Connecting Asterisk to Legacy PABX's" and then extrapolate that information to suit your needs.

RE: [Asterisk-Users] * point to point t1 solution?
That would not be a nailed up t1 - signaling at both ends would be via asterisk.
I was trying to determine if there is a way to configure asterisk to emulate a
ptp t1 passively (no signaling) - essentially providing the same type of end to
end circuit you would get if you ordered a point to point esf/b8zs t1 from the
telco.
I know how to set up asterisk to talk to the Nortel (where the Nortel thinks
asterisk is a telco trunk) - but that is not my goal here.
I want to replace a T1 TIE TRUNK between to Nortel's using Digium t1 interfaces
and an IP link between asterisk boxes, but still allow the Nortel to pass
signaling directly back and forth.
Still want to take the challenge?

Yes, I think Asterisk can do what you are trying to achieve. No, I don't
know how to do it, and no I won't do it for you since I've never been in
the situation you're in.
As for web based hints, with some experience I've found that google is

If that still doesn't work, shelling out a few hundred bucks for a

other alternative, and is often a good deal.

RE: [Asterisk-Users] * point to point t1 solution?
TDMoE would allow a T1 like connection only over the local Ethernet segment,
since it is not an IP technology it can not be router across ip networks.
This would be useful to connect 2 asterisk boxes on the same Ethernet segment
(or with a crossover cable).
The advantage would be lower latency than SIP or IAX - the disadvantage being a
constant ~1000 packet per second Ethernet flow requires to keep the channels up.
Won't work...

Re: [Asterisk-Users] * point to point t1 solution?
Damon,Unless I misunderstand what you are looking for, a P2P T1 would be handled by the kernel, not by asterisk. If you want to use digium cards, you would still need zaptel, or you could use a sangoma card on each end and their wanrouter drivers. Asterisk would obviously be involved in the SIP or IAX connection to pass calls, but not with the P2P T1. This page may help: http://voip-info.org/wiki/view/Asterisk+Data+ConfigurationThis is based on a T1 using Cisco HDLC, but I have done the same thing with PPP.

This has been an interesting discussion for me (except for the sniping). The last post led me, out of curiosity, to this wiki entry: http://www.voip-info.org/wiki-Asterisk+TDMoE I was unaware of this feature, and it looks pretty good. I've been pondering replacing some T1's by leveraging IP capacity but of course have run up against the QoS issue. My idea was different... I don't have production experience with precisely this type of application, but I ask for validation from this list. Pardon me for stating what is undoubtedly obvious to many... The key to assuring adequate performance in replacing a TDM link with IP is to assure that adequate idle time is reserved for voice on the IP segment(s) involved in the route. In this way, latency can be stabilized, and if maintained below a certain (arbitrary) threshold, performance can be deemed acceptable. The first step, of course, is to assure that the virtual TDM allocation does not exceed the available IP bandwidth (so leave a margin, which is huge in the example given). The next step is to use routers which respect the TOS field (however it is used; diffserv/whatever), and finally, to assure that no non-VoIP traffic can be injected into the path with higher routing priority. On a point-to-point link, a pair of typical Linux boxes can do all this. Given the original problem, I would place Asterisk boxes at either end of the link, and have them blend the ordinary traffic with the VoIP traffic (which would probably use IAX to relay calls between the T1s), while assuring (enforcing) that VoIP packets are marked as highest priority. There are varied ways of accomplishing this, and a good reference which I've used in the past can be found at: http://www.lartc.org/lartc.html Additionally, I think one could use the tunneling techniques described in that guide to encapsulate the non-VoIP traffic such that its packets' originally marked TOS values are preserved for transit outside the segment used for TDM emulation. In this way, that part of the segment bandwidth not required for VoIP would function as a dedicated link, allowing other prioritization of traffic such as interactive vs. bulk (or even other voice!), with the added advantage that it could use the reserved VoIP bandwidth when it is otherwise not required (albeit in the case of a T-1 over 10Mb, that's insignificant).

Thanks Matt, PRI signalling means that calls and answered and dialed (aka signalled) by asterisk, the goal is to maintain the signalling between the two nortel boxes.

RE: [Asterisk-Users] * point to point t1 solution? / alternatives
I've seen this discussion before. The conclusion was, it is possible to route TDMoE through a VPN tunnel depending on the tunnel setup you are using (bridge + tunnel for example) however the latency would make it useless. TDMoE is designed for the same network. Unfortuanely I can't find a link for it, but I remember it distinctly. Another, large issue, is that TDMoE uses T1 - style bandwidth constantly whether it is in use or not. Even if it were possible to route it, and even if the latency problem was solved, can you imagine your bandwidth surcharge of ~1.5Mbps constant? At the end of the day, emulating TDM through the use of IAX and a well written dialplan is totally the way to go. -Original Message- From: Steve Langstaff [mailto:[EMAIL PROTECTED] Sent: Thursday, January 26, 2006 8:16 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] * point to point t1 solution? / alternatives Remember, however that TDMoE is TDMoE, not TDMoIP - it's not routable (unless you encapsulate it somehow, I guess). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Bill Michaelson Sent: 26 January 2006 14:58 To: asterisk-users@lists.digium.com Cc: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] * point to point t1 solution? / alternatives This has been an interesting discussion for me (except for the sniping).

To: Asterisk Users Mailing List - Non-Commercial Discussion asterisk-users@lists.digium.com Can anyone point me to a reference or sample config for bypassing a nailed up (point to point) t1 between two PBXs with asterisk and a pair of t1 cards? Right now I have 2 Nortel norstars connected to each other via a leased line t1. I also have a solid 10mbps low latency microwave link between the 2 sites. My goal is to run an asterisk box at each end with a t1 card and Ethernet card to act as a TDMSIP gateway to bypass the nailed T1 in a relatively dumb configuration, with the goal of migrating off of the norstars eventually. In past situations I would have done this with a pair of Cisco routers with T1 interfaces in them but in this case I want to get asterisk into the picture as an eventual replacement for the norstars. ___ --Bandwidth and Colocation provided

She ain't cheap, but this'll work: http://www.blackboxcanada.com/Catalog/Detail.aspx?cid=381mid=4291 It's TDMoIP so 2 T1 boxes tied together should work like this: T1--TDMXX card--Asterisk--TDMXX card--Voice Mux--Broadband--Voice Mux--TDMXX card --Asterisk at about $7K Cdn it'd be worthwhile to rewrite a dialplan to use IAX instead. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Damon Estep wrote: Thanks Matt, PRI signalling means that calls and answered and dialed (aka signalled) by asterisk, the goal is to maintain the signalling between the two nortel boxes. I have gathered that raw point to point circuit emulation is not possible on asterisk... To connect the channels of the T1 straight through would be by using a Digital Access Cross Connect system (DACS in proprietary ATT lingo). I believe there is this capability in zaptel, though this does not seem like the best option. As mentioned before, the ISDN PRI signaling seems like a much better solution. I am aware of how to connect a PBX to asterisk using ISDN PRI signalling. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] * point to point t1 solution?
Damon, I have not done TDMoE, but I do know that in the wireless world If I wanted to move T1s over a wireless link, I would look at Western Multiplex. Just off the top of my head.. I have seen the 10 + 2T perform this function. This was a few years, ago, so I am sure that there is some newer MUX gear that can move the Ts.
