[asterisk-users] t1 cards
I presently need to connect a few channels of voice and data between multiple locations where I own the copper between them. Each location exceeds 300M from any other location. I'm thinking of generating T1's and running those between locations. If I use PC based cards wired back to back (I can do that, right?) what kind of distance can I expect to be able to span without needing repeaters? What inexpensive cards can you recommend for use with asterisk? I'm considering either digium or sangoma. Would I get any better performance if I used a sync-serial card connected to a separate csu/dsu?

Re: [asterisk-users] t1 cards
yes, more than 300 meters (longer than copper based ethernet allows). Yes to E1, as I understand it, it's just a config change on many cards anyway. I'm specificly looking at pci based t1/e1 cards because I'm finding single port cards on ebay going for 100-200 usd. in some cases I may want to drive a channel bank at the far end, thus t1/e1. anyone have experience on how far these pci based cards will drive when wired back to back?

without any other hardware than 2 bare ass pci based t1/e1 cards wired back to back how far can one go between them? additional hardware defeats the purpose.

Re: [asterisk-users] t1 cards
T1 is NOT DSL. Most T1 links you purchase now are brought into your building with a type of DSL conversion to extend the distance between repeaters/amplifiers. T1 is purely a digital signal. DSL converts the ones and zeros to audio(multiple tones to provide multi channels of data). A simple analogy is comparing a T1 to DSL as a serial port to a modem. Back in the old days before fiber, copper T1's between CO's had their repeaters placed aproximately 1 mile apart. Best case going T1 port to T1 port, I would not expect this to work reliably at distances greater than one mile or 1.6 km but that does depend on the quality of the cable also. But in my mind, I would be seriously concerned about lightening protection. I have been around telco's and privately owned facilities for a long time and see lightening to be a very serious issue in this scenerio. I have seen short distance copper replaced by fiber because of issues over time with lightening damage despite having proper telco grade protection. Lyle Jeff LaCoursiere wrote: I would say miles.

Re: [asterisk-users] t1 cards
How much further than 300m? It might be very well possible to just lower the speed to 10M and just use that If you already have some quality Cat5 cable between both points it's worth a shot. I support some sites with this arrangement and I've had to find 10M hubs for replacement hardware (the previous guy insisted that only a particular model HP print server would work, coincidently that model only has a 10M Ethernet port)... it's not something I would advise someone to setup but if cost is a concern I wouldn't rule it out -- it certainly can work and be reliable in the real world.

Re: [asterisk-users] t1 cards
Here's a couple of distances I'm looking to cover (distances are +- 10%): 1 at 400M 1 at 600M 1 at 1800M 1 at 2400M some of these links may already have pots circuits complete with occasional ringing voltage in the same conduit (but likely not the same cable). how far can I push the distance of E1 over copper using only 2 cards back to back?
