It's probably not a modem, but it may be encoding the bits with

imagine it speaks Frame Relay or something and translates the

multiplexes the signal into a DS3 with you and several other Utopia
users. Whatever the case, it is most likely not a modem.

From this diagram: http://www.utopianet.org/technology/layers.htm
it seems that it's 100Mbps ethernet before it hits the house, so the
box would be some sort of ethernet bridge to change media from fiber
to UTP. If they run Sonet at all, it's not what's going up to the
house.
