Applications
The AT&T MERLIN Legend was the dominant business telephone system platform throughout the 1980s and 1990s, widely deployed in offices, call centers, and multi-location businesses. The 517C20B DID card was a standard upgrade module that allowed companies to subscribe to Direct Inward Dialing service from their local telephone carriers, enabling direct external dialing to department extensions and reducing the need for switchboard operators. DID trunks remain a valuable feature in modern telecommunications and are still used in legacy system maintenance and upgrade scenarios. This card is compatible with any MERLIN Legend system running any version of Legend software, making it a versatile addition to upgrade or replace failed DID modules in existing installations.
This AT&T 517C20B MERLIN 8 DID Trunks Card (800DID) has been inspected and appears to be in good used condition. The card was pulled from a working telephone system environment. It supports up to 8 Direct Inward Dialing (DID) trunks and is compatible with all AT&T Legend software releases. Please review the product photos and contact us with any questions before purchasing.
