Nortel NTYS05ACE6 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTYS05ACE6 is a Nortel IP Phone 1140E in Graphite finish, a mid-range six-line business IP handset from Nortel’s (later Avaya’s) 1100-series desk phone range built for the Communication Server 1000 and BCM PBX platforms. The 1140E offers a backlit greyscale display, six programmable line/feature keys with a further eight via expansion, a built-in Gigabit Ethernet pass-through port for a co-located PC, and full-duplex speakerphone audio, positioning it as the volume mid-tier model between the entry-level 1120E and the higher-specification 1150E/2050. Nortel and Avaya 1100-series phones remain widely deployed on CS 1000 and BCM sites, and genuine handsets such as this one are a routine requirement for fleet expansion, desk moves and like-for-like replacement of failed units, since the platform remains supported on a large installed base even where new procurement has slowed. Specifiers should confirm exact firmware and signalling (UNIStim vs SIP) compatibility against their specific call-server configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel IP phones to support ongoing network maintenance projects.
