The “DH42” accommodates two traditional POTS (Plain Old Telephone System) lines, as well as two voice-over-IP lines in one 19 inch 1 RU enclosure. Essentially a four-line conferencing hybrid, DH42 allows callers to be put on-air with separate send and receive paths, filtering, AGC and control functions.
VoIP telephone lines offer a low-cost alternate to traditional analog POTS lines, and VoIP technology also is found in SIP-based PBX telephone systems. DH42 offers broadcasters the ability to interface their Internet-based VoIP lines or VoIP PBX lines with audio consoles and other broadcast audio equipment.
“DH42 represents the natural evolution of the broadcast telephone interface by blending the technology legacy POTS with voice-over-IP technology,” said Kris Bobo, managing director of Comrex. “Our customers have been seeking a professional broadcast solution for interfacing VoIP lines. We’re pleased to offer them a solution that bridges both technologies.”
