We have a device that in the case of power loss, will release a relay
contact that will connect a standard phone to phone lines. Under normal
operation there is no connection, voice is digitized and Ethernet Packatized
and sent out fiber optic cables.
We do not design or supply the phone, which would have to have all of
the FCC part 68 and RT &T directives met. We just allow a copper path to be
made.
So my first thoughts are that I am closer to being just a hunk of
telephone hook-up wire than a phone or modem, but I will need to protect the
physical relay inside my box appropriately, meeting the ITE standard UL 60950
and EN 60950 appropriately, but not the full requirements of the other
referenced standards.
What say ye sages?
Thanks
Gary
