Nortel NTYS20AA70E6 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTYS20AA70E6 is a Nortel IP Phone 1230, a two-line business IP handset from Nortel’s (later Avaya’s) 1200-series desk phone range built for the Communication Server 1000 platform. The 1230 sits at the upper end of the 1200 series, adding a backlit greyscale display and additional programmable feature keys over the entry-level 1210/1220 models, while keeping the compact form factor and UNIStim signalling common across the range. CS 1000 sites with a mixed 1200-series handset fleet use the 1230 for users who need more line appearances or feature access than the base models provide without stepping up to the larger 1100-series phones. Nortel and Avaya CS 1000 deployments remain widely in service, and genuine handsets such as this one are a routine requirement for fleet expansion and like-for-like replacement of failed units. Specifiers should confirm exact firmware and signalling 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.
