For sale is a genuine Dialogic DTI/211 ISA Card (part number 09-0076-002, also referenced with 96-0040-002). This is a classic digital telephony interface board designed for legacy T1 (DS1) trunk connections in voice processing, IVR (Interactive Voice Response), call center, and computer telephony integration (CTI) systems.

• Interface: Single T1 digital trunk (24 channels / 1.544 Mbps)

• Bus: Standard 16-bit ISA (for older PCs/servers)

• Function: Provides digital network interface for T1 lines, including framing, signaling, and time-slot multiplexing. Works with Dialogic voice/fax resource boards via the SCbus or similar for full telephony applications.

• Common Uses: Legacy PBX integration, predictive dialers, automated attendant systems, voice mail, fax servers, and other Dialogic-based CTI solutions from the 90s/early 2000s. 

This is a hard-to-find piece of telephony history. Perfect for maintaining or restoring older Dialogic systems, hobbyist retro computing projects, or specialized industrial/legacy telecom setups.

What’s Included: The ISA card only (no cables, software, drivers, or documentation unless specified). Software/drivers for older OSes (Windows NT, etc.) are typically available via archives or Dialogic support sites.

Compatibility Note: ISA bus hardware – designed for vintage systems. Not plug-and-play with modern PCs.
