Hello,
I run Crocker Communications (AS7849) and have ARIN allocations of
161.77.0.0/16 & 66.59.48.0/20. The 66.58.48.0/20 space was used for our
datacenter which shutdown a couple years ago. The space has mostly been
dormant for the past couple years. I’m now starting to assign

Could you use a transceiver for the 1000Base-T? copper <-> fiber <-> copper
that will create an ‘air gap’ on the data circuit. You still run the risk of
a lightning strike entering through the transceiver power. You could filter
that through a -48VDC power supply, rectifier/inverter pair.

Hello,
I’m just getting started setting up communities for my network. Is there any
standard convention for community numbering (*:666 for RTBH for example)?
I’ve looked at some examples from other carriers and it looks like everyone
does their own thing.

You can’t push a T1 through a load-coil which are normally placed every mile on
