<<ADSL vendors take part in test
By Jack Robertson
Several equipment vendors hope to parlay an MCI Communications Corp. test of asymmetric digital subscriber line (ADSL) service in Iowa into future business.
Working with Northwest Iowa Telephone Co. in a test in Sergeant Bluff, Iowa, MCI is delivering broadband TV signals via conventional twisted-pair copper wire over distances of more than 2 miles. MCI said it is the first test of MPEG-2 digital video ever carried out over plain old telephone wires.
NEC America Inc.'s Public Networks Group has installed a video switching system in the local telephone company's central office. Subscribers are using NEC-built ADSL transceivers, telephone service splitters, and set-top boxes connected to their regular phone lines to receive the TV service.
Amati Communications Corp., San Jose, is providing a 6-Mbit/s modem that plugs in to the NEC home set-top box. PairGain Technologies, Tustin, Calif., has installed its Megabit Modem at the local phone company's customer service center for real-time monitoring of the network service. The PairGain modem provides a data path from the central office to the service center.
Tut Systems Inc., Pleasant Hill, Calif., and Westell Technologies Inc., Oswego, Ill., also supplied ADSL modems and terminals used in the MCI trial.
In another ADSL development, an ad hoc industry group is drafting a proposed standard for next-generation rate-adaptive DSL technology. The specification will be submitted to the American National Standards Institute to supplement existing ADSL standards.>> |
