[cisco-voip] lightning/surge protection on analog ports for emergency poles

[Lelio Fulgenzi]

ok thanks. the panamax site talks about a $5,000,000 coverage. we'd have to make sure what the fine print is and whether they need to 'certify' the install and attached devices.

  so long as it works you will be fine, but if it doesn't you will have a burnt pizza box.  I've seen several cases of this.  No way to know what the load was that toasted the box, but the high rate of occurrence leads me to believe it's a pretty low threshold.

      The vg248 does not comply to Bellcore specs for off premise extensions.  i.e. it doesn't have overload protection.  the vic-2 and vic-4 FXS modules for routers do have proper overload protection to minimize damage.

        What have others done for protection against the elements on their analog ports? We have a few emergency poles on our campus that get hit by lightning a few times a year, and where we understand there will be some replacement parts necessary, we don't want this thing travelling down the wirepath to our vg248 and blowing that thing up.
