HI

Hopefully someone out there has a working SPA 3000 on a uk exchange line and wouldnt mind sharing their settings.

When I call the line it shows a line voltage of -50v , i tried -50 in the regional settings for ring voltage with no effect.

The ring spec in regional shows

Sinusoid wave form , 25 frequency, -50 ring voltage (was 50) , cwt frequency of 440@-10

Under misc in regional I have Input and output gains to -3 , power limit of 3 and impedance 370+620|310

Under PSTN tab I have

Impedance 370+620|310 ring freq 25, max nothing, both gains are 0 tip/ring of 3.5v, current 10ma, line in use 30ma, ring validation 512ms, ring indication delay 512ms, timeout 640ms, threshold 19.35-23.65 ringer impedance high.

Im a newbie with the SPA stuff so if anyone has a full set of working UK settings to use that would be great, as ive not gotten into any of the call progress stuff yet and I assume thats going to cause me a problem too and maybe callerid too...

Thanks in advance

Regards
John

Try Trapezoid and up the voltage to 70V. Frequency should be 25Hz for UK, but it might be 20Hz.

Once you have downloaded the UK settings from Voxilla, you only need to change the impedance (in Regional and PSTN Line) to 370+620||310nF.

There are at least 50 UK users on here, successfully using the SPA 3000, I have one on my BT line and another on an extension port of my PBX which only presents 27V on hook, the only additional change I made was to reduce the
