Hi,

We are replacing the dead phones (they die completely) with the same model M7310 (not t series).

Underground cable - it is 2 x 25 pair cable bundles run though a 2 inch PVC pipe. The guage looks to be 24.

I don't think the unused pairs are grounded, they are just punched down.

It is probably up to 1000 feet from ksu to phones.

Lightning protection - the ksu is protected by our central building UPS. Other than this there is no other protection.

Thanks!
