Applications
The TIE Communications DTS Systems/ONYX IV is a business PBX platform from the late 1980s to early 1990s, designed for small-to-medium enterprises needing multi-line telephony with centralized call control. The ONYX IV line supported analog station sets and provided features typical of that era — including trunk line management, station-to-station dialing, call transfer, and system interlink for networked PBX configurations via the SIM-A module. The 12-SCU-A station cards each support 12 analog station ports, making this configuration suitable for an office of up to 60 extensions. These systems are still sought by facilities running legacy TIE/ONYX telephone infrastructure, hobbyists, or technicians needing spares and working modules for existing installations.
This TIE Communications DTS Systems ONYX IV PBX has been inspected and is in good condition. The cabinet is structurally sound with normal cosmetic wear consistent with used telecom equipment. All cards listed in the specifications — including the 88340 H-CPU-A central processor, five 88110B line cards, five 88120 station cards, 88135 trunk protector, and 88275 SIM module — are installed and present.
