Applications
The NEC NEAX 2000 IVS was a widely deployed enterprise PBX and integrated voice server platform introduced in the 1990s and used throughout the 2000s in mid-to-large business telephony environments. The NEAX 2000 IVS supported both analog and digital station lines through a modular card architecture — cards like the 4DLCQ slot into the system's card cage to provide digital extension ports for NEC digital desk phones. These cards remain in demand for maintenance and expansion of existing NEAX 2000 IVS installations, where operators keep legacy systems running rather than replacing the full platform.
