In my church, we are planning on burying a PVC conduit from the
office building to the church building for telephones and
internet connection. The plan is to put in 1 cat5e for internet
and 3 cat5e for telephone ... the office digital phone system
uses RJ-45/cat5e. My question is, will the standard gray PVC
conduit hold up underground. Will is crack due to ground
freezing and thawing? We are near Chicago, so the frost line
can go down 4 feet. Would it be better to get direct burial
cat5e and use that without the conduit? BTW, the distance is
about 250 feet, so that shouldn't be a problem with the phone
system or internet connection (router/broadband cable modem).
