Tollgrade Makes DOCSIS Grade

Tollgrade Communications Inc. said Monday that its Data Over Cable Service Interface Specification status-monitoring transponder has been awarded Cable Television Laboratories Inc.'s “CableLabs Certified” status.

The vendor of communications test and management solutions for telecommunications and cable broadband said its “Model 1.0.0” transponder “merges the benefits of cable-industry standard SCTE-HMS [Society of Cable Telecommunications Engineers-Hybrid Management Sub-Layer] status monitoring and the DOCSIS specifications, and helps operators to lower costs and improve efficiencies in monitoring their cable plant by transporting HMS-status-monitoring data over the shared, revenue-producing DOCSIS infrastructure.”

“Tollgrade continues to expand its product line to meet the evolving needs of the status-monitoring marketplace,” Tollgrade executive vice president of marketing Greg Quiggle said in a prepared statement. "DOCSIS transponders are the next logical step in status monitoring technology."
