GPON is TDM (Time Division Multiplexing). The downstream is essentially OC-48
(2.4Gbps). The OLT sets the clock and each ONT has a specific timeslot for
uploading. Some vendors can adjust the timeslot reservations to ‘guarantee’
specific upload speeds to specific ONTs

At this point I've basically given up and I'm moving the 66.59.48.x IPs to a
new datacenter over the weekend. I'll move the DNS servers on the old IPs to
the new datacenter and call it a day. We are trying to get all of the
customers to re-register anyway, then I'll shut all of this down.

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.
+1 Kentik as well, DDoS, RTBH, Netflow. Cloud based so I don't have to worry
about it.

You can’t push a T1 through a load-coil which are normally placed every mile on
copper. Typically the telco would cut the load-coil out of the 2 T1 pairs and
install a repeater to push the T1 the next mile. That is with a traditional T1
circuit. Most T1s these days are 2 wire HDSL which

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.
