Not talking about MDF/CO/MMR or whatever you call the aggregation point.
While you've made it clear that you don't let Service Providers play
around in that aggregation point, you didn't define (or perhaps I missed
it) the responsabilities for work at homes.


When municipality does the buildout, does it just pass homes, or does it
actually connect every home ?

When "passing homes", you would generally have pre-built taps such as
Corning FlexNAPs along the cable so that a strand can be added quickly
between the tap at telephone pole and the home wanting to get service.
You only connect homes that subscribe to your service. (so you have to
decide who is responsible for stringing fibre from telephone pole to the
home when end user subscribes to a Service Provider's services.

Not entirely sure what sort of methods they use when it is an
underground cable plant. (perhaps more likely to see fibre brought to
each home during the dig, perhaps not).


In any event,  you still have to worry about responsability if you allow
Service Providers to install their on ONT or whatever CPE equipment in
homes. If they damage the fibre cable when customer unsubscribes, who is
responsible for the costs of repair ? (consider a case where either
homeowner or SP just cuts the fibre as it comes out of wall when taking
the ONT out to be returned to the SP.


In Canada, the wholesale regime gives the owner of the cable plant
(telco or cableco) responsibility for all installs even for independent
ISPs. However, independent ISPs are responsible for providing approved
modems to their customers. (different for VDSL where the telco provides
the modems even for custoemrs of indy ISPs since the modems are
customized to work with the VDSL DSLAMS selected by the telcos). In the
case of cable companies, they have a list of approved DOCIS modems they
allow independent ISPs to sell to teir customers.

We'll see in the next few months what will transpire for a wholesale
FTTH access in terms of responsabilities for CPE equipment (ONT, battery
backup etc).
