thing that Ground Start has that I think makes it imperative is a call
disconnect advantage. There has been 1 install, a CME install, where we had
the telco switch over to ground start because we kept getting circuit hangs. <o:p></o:p></span></p>

<p class=MsoNormal>I just finished setting up an SRST site in PR and tried
using LoopStart with the carrier there. Had nothing but headaches due to the
carrier not sending the correct disconnect signal on the line.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I used the typical timeout timers in the config and that
worked about 70% of the time. But if the call went unanswered and the AA picked
up then the port would stay off-hook for about 5 mins till the AA would time
out even if the calling party hung up. We got TAC involved and they
confirmed what we saw. We ended up having the carrier switch the lines to
GroundStart and have been happy since.<o:p></o:p></p>

<p class=MsoNormal>I guess it depends on carriers and regions.<o:p></o:p></p>

<p class=MsoNormal>Loopstart = easier install (90+% of installs if I had to
guess), no earth ground required, low likelihood of of audio hum<br>
<br>
Groundstart = MUCH less common, earth ground required and not always readily
available, almost no hum.<br>

For analog lines from the PSTN:<br>
Loopstart bad<br>
Groundstart good<br>

The application is I'm bringing up a small SRST site, and we are replacing they're
old key phone system. I have no idea what the existing lines are, but we
have enough time to change the type out.<br>
