Powerline Communications

Service Unit

Service UnitThe service unit is a wall or table mountable multi-purpose data communications box. The unit facilitates data connections via BNC connectors to cable modems and telephone connections via standard line termination jacks.

The service unit provides its own line power for ringing and contains a battery backup in case of power outage. Alternative Differential Pulse Code Modulation (ADPCM) is used for speech sampling.

Because Digital PowerLine allows for the termination of multiple radio signals at the customer premises, the service unit can facilitate various Customer Premises Equipment (CPE) simultaneously. In a manner similar to ISDN, data (computers) and voice (telephones) devices can coexist without interfering with each other.
