RE: [EFM] EFM Requirements
Harry,
But I
thought we (EFM) are not dealing with OAM&P issues as to
'plug
and play ONUs'? Where the demark point is, seems to me, is
not
crucial to the plug and play ONUs.
A
fully plug and play ONU actually involves more than just demark point but
also
the
application that will deal with:
1.
loop qualification
2. PC
installation software
3.
Diagnostic software such as ping or traceroute
I am
not sure this is something we need to talk about at this forum but I do
agree
with
you that 'no truck roll' is essential to the deployment of the EFM
technology.
But I
also agree with Geoff that where the demark point is probably is besides
the
point.

Geoff,
Whether the truck roll is required may be a big deal. Given the current
cable modem costs, the service call expense may be too
dear.
There is nothing that prevents a self installable ONU box from
providing a network demark function. The ONU can act as a managed network
element reachable from the provider network, while offering a layer 2 data
forwarding function to the subscriber only.

Sherm-
I do not agree.
Our
discussion to date have pretty well driven us to the conclusion that there
will have to be a piece of demarcationir equipment that will isolate the
line, at least in the frequency range above voice.
Whether this box
requires a truck roll or can be purchased by the consumer and self-installed
is pretty much beside the point. The box will have to provide the
demarcation function and have functionality (if not hardware) that is owned
by the service provider in order to meet their OA&M
requirements.
Further, we can not expect Service Providers who are
operating at the Nyquist limit to be willing to coexist with and guarantee
service in an environment with every piece of uncontrolled hobby gear that a
homeowner has a right to plug into a phone jack.
I predict that
isolation and demarcation will not be optional.
