Tut Systems piggybacks data connection on phone wiring

Pleasing the people used to mean the promise of a chicken in every pot. Then it was a

Tut Systems Inc. of Pleasant Hill, Calif., is aiming at what it believes is a $100

interface card, or line card, plugs each user’s PC directly into an existing phone
jack. Telephones can be used normally.

The Expresso chassis’ central shelf accommodates the WAN interface card and up to
17 eight-port HomeRun line cards, permitting up to 136 line-side subscriber connections.
Up to eight of the shelves can connect via 100-Mbps Fast Ethernet for a maximum of 1,088
ports. The HomeRun line cards in turn connect to existing copper pairs serving single

The Expresso MDU 2000 chassis, including power supply, one network management card and
one multiplexer card, sells for about $5,000. Eight HomeRun line cards cost $2,695.
