Fiber1000 new installation

Is there a diagram that illustrates the connectivity flow?  I've read conflicting information as to the actual build out.  What comes into my residence?  What type of interface is mounted?  Where is it mounted?  What type of connection(s)?  What is the connection to the modem?  Knowing the modem type and model would be helpful as well.

I want to be able to extend my demarq with preferably a fiber jumper or I can use existing cabling.

It depends.

Your installation may be an ONT and a Gateway (Arris 5268AC, BGW 210, or BGW 320) connected via Ethernet.  Or it could be a BGW 320 Gateway with an integrated FSP module that acts as the ONT; AT&T would terminate the fiber to a Fiber jack in the wall, and give you a fiber drop from the wall to the BGW 320 FSP.

Which you get depends largely on the technology being used in your area and what your installer has been provided.

There is not a separate "modem," only one of the Gateways (integrated Modem/Router/SIP client) in a box.  The ONT and Gateway require power.

Many thanks!  Any way to determine by area what is system is being used?  The fiber has been installed within the last three years.

I think they're converting from GPON to XGS-PON and the SPF/BGW 320 is required for XGS-PON.  Others may know more about that rollout, but I do not.

Thank you again.  My assumption would be that the fiber jumper is OM3 50/125 with SC connectors.  I appreciate the clarifications.

SC/APC fiber jumpers

Most locations are GPON using the 010 ONT (white) while a few are XPON using the 020 ONT (black) based upon type of splitter installed at the PFP.

The 320 can be either but needs the correct plug in... common would be GREEN SFP for GPON...

Our area has been short of XPON equipment, both the 020 and SFP, for past several months with XPON orders being rescheduled to a later date when hopefully the equipment will be available.

Install day today.  Very simple question.  I will have five public IP's.  Initially I want to land two of those on devices.  I am somewhat familiar with IP-Passthrough but have never used two public IP's.  This about the ONLY negative to migrating from Charter.  They hand off a wire and make it very easy to use the Public IP's.

Are there any gotchas?

Thanks in advance.

The block of 8 (5 usable) public IPs can be handled by the Gateway on its LAN interface.  You just hard assign the devices the public IP address and give the .6 Gateway address as the default Gateway and they'll route.  There is an option to DHCP assign the publics on the Gateway's LAN, but I'm far from certain how that works.

Or you can put a router behind your gateway to handle the subnet and let it do what you want.

Note that in addition to the static block you still have the Dynamic Public Address, you don't lose that, with NAT and everything good and bad with that.  They operate in parallel.
