Applications

The Telrad Digital Key-bx was a proprietary digital key telephone system widely deployed in small-to-medium business environments from the 1980s through the 1990s. The 79-500-0000/B DAP set served as a full-featured station in these systems, providing attendants and power users with direct-line access, feature control, and hands-free operation. Because Key-bx systems used proprietary digital signaling, this phone works only with Telrad Digital Key-bx equipment — it is not compatible with standard analog lines or other PBX platforms. It remains sought after as a replacement station set for organizations still running legacy Telrad Key-bx infrastructure.
