Applications
The Nortel Meridian M5209T is a feature-set ISDN telephone from Nortel's Meridian line, designed for use as a digital station within Nortel Meridian 1 (M1) enterprise PBX systems. The Meridian 1 was one of the most widely deployed business telephone platforms of the 1980s and 1990s, installed in corporate offices, government agencies, universities, and healthcare facilities worldwide. These sets are commonly sought today for replacement or spare use in facilities still running legacy Meridian 1 infrastructure, as well as by collectors of vintage business telecom equipment. The M5209T's ISDN interface and programmable key layout made it suitable for executive or administrative desktop use within large multi-line office environments.
This Nortel Meridian M5209T NTBX90 ISDN office telephone is being sold AS-IS as it has not been tested or powered on at our facility. No functionality is guaranteed. The phone body appears to be in good cosmetic shape with typical light shelf wear; the ASH finish is intact with no significant cracking or damage visible. The unit does not include a handset, power supply, or keycap kit (NTBX93AD). What IS included is shown in the photos: the telephone base, a phone line cord, the Voice Users Guide (NTBX93AE), and a Data Communication Guide.
