Comrex says its new digital telephone hybrid is designed to adapt to the changing requirements of broadcasters.
The DH42 accommodates two traditional POTS (Plain Old Telephone System) lines as well as two Voice-over-IP (VoIP) lines in a 19 inch 1U rack-mount 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 lets broadcasters interface their Internet-based VoIP lines or VoIP PBX lines with audio consoles and other professional broadcast audio equipment.
“DH42 represents the natural evolution of the broadcast telephone interface by blending the technology legacy POTS with VoIP technology,” said Kris Bobo, managing director of Comrex.
