Nortel NTYS05CAE6 (telecommunications transmission and networking portfolio) Power Supply

The Nortel NTYS05CAE6 is an IP Phone 1140E in graphite with icon keys, running the SIP protocol variant, supplied without its power supply for installations running from Power over Ethernet (those without PoE should order the separate NTYS17-series power supply). The 1140E is a mid-range six-line IP deskphone in Nortel’s 1100-series range, offering a backlit greyscale display, dual-port Gigabit switch and the icon-key layout used across this generation of Nortel/Avaya deskphones. Tech-Star supplies this as a secondary-market unit for maintaining or expanding an existing SIP-based 1140E deployment. The 1140E’s SIP firmware variant is distinct from the UNIStim variant used on CS1000 deployments, so buyers should confirm which signalling protocol their system runs before ordering, since the two are not interchangeable without a firmware reflash.
