| rudholm | and he's right |
| ManxPower | rudholm: I'm using an Adtran TA750 for the POTS connections |
| rudholm | ah |
| ManxPower | rudholm: what about HPEC? |
| rudholm | I'm just using the software EC tried adjusting it getting levels and tail right |
| ManxPower | rudholm: the HPEC is free for analog cards under warrenty |
| rudholm | got echo down a bit, but not eliminated |
| ManxPower | for me the HPEC eliminated ALL echo. Of course it also eliminated ALL AUDIO, but I'm sure they will fix that. |
| Strom_M | hahahaaha |
| rudholm | hahaha I haven't experimented with it perhaps I should I'm tired of hearing callers |
| ManxPower | rudholm: you should. |
| rudholm | when I call Strom, connection is perfect |
| ManxPower | I also have a Tellabs EC card or 4 around here. |
| rudholm | but that's an IAX link direct between Asterisks |
| ManxPower | I should set up an IAX2 test number on my server, the one that is on satellite |
| rudholm | Strom_M: sometimes I dial into Phil's step switch just to hear it :) love that fog-horn busy signal :) |
| Strom_M | :) |
| ManxPower | Strom_M: I don't suppose you know off the top of your head the expected voltages for on hook and off hook top to grnd, ring to grnd and tip to ring? |
| Strom_M | tip to ring should be 48vDC, IIRC dunno about ground |
| rudholm | tip and ground are close to the same potential, but not quite in fact, iirc, there's more potential between ring and ground than there is between tip and ring I just measured all the voltages on the other day er, other week, I guess lemme dig it up |
| ManxPower | ring to tip I get 48VDC, ring to grnd I get -46VDC, and tip to grnd I get 0VDC |
| rudholm | that sounds reasonable |
| ManxPower | I want to make sure my test equipment is not out of whack |
| rudholm | what kind of equipment? |
| ManxPower | Sage Instruments 930A Got it off eBay about a month before Katrina. This is the first time I've needed it AND it was not in storage |
| rudholm | ok, here's what I found on my analog line these are all WRT earth On-Hook: Tip: +0.34 Ring: -51.8 (so my T-R potential is over 52V) |
