A totally new install. I was very anxious about them showing up at all, since nobody came to do any digging prior. Turns out that they ran everything overhead, since my property was a good challenge for underground. A key point is that you should let them know up front that you know are technically into this stuff and would like to help as much as possible.
Time to run the fiber and get all the hardware "boxes" in place was about 2 hours. Understand that this involved rebuilding my homebrew RF / phone / ethernet distribution panel. After that, they took 2 1/2+ hours to wire the ONT, battery backup, ActionTec router (nice), coax, phone, etc. Your install should go a lot quicker, since all you need is the RF.
Ask them to let you install the STB. When they saw my main system, they handed me the STB and asked if I could do it (I think it scared them
). They will give you whatever cables you need except TOS-link.
Add another 1/2 hour for the techs on hold with their own tech support line. Result was to download software to the configure the ONT (it was not done).
Hint: Take a look at your existing RF system and plan accordingly to save time. The ONT output is +18 dBmV (see my previous post about signal levels). My Channelvision distribution amp was replaced with an 8-way passive splitter.
