Farallon Netopia PN660-DDS DDS Router For Parts Not Working 100-240V

The Farallon Netopia PN660-DDS is a desktop DDS (Digital Data Service) WAN router designed to connect a local network to a DDS leased-line circuit. It carries dual brand identity — manufactured by Farallon Communications of Alameda, CA and marketed under the Netopia brand — and was targeted at small-business and branch-office connectivity over synchronous digital lines. This unit does not power on and is being sold strictly AS-IS for parts or repair.

Applications

DDS (Digital Data Service) routers like the PN660-DDS were used in the 1990s to connect small business and branch-office LANs to synchronous leased-line DDS circuits offered by telephone carriers — point-to-point digital lines running at fixed speeds (typically 2.4, 4.8, 9.6, 19.2, or 56 Kbps). The Farallon/Netopia PN660 series sat at the customer premises, bridging the LAN-side Ethernet or token-ring segment to the carrier's DDS local loop via a CSU/DSU. DDS was a predecessor to fractional T1 and Frame Relay services, and equipment like this was eventually displaced by higher-speed broadband and T1/fractional-T1 routers. Today, units like this are primarily sought for parts, repair bench use, legacy network restoration, or vintage networking collections.
