NEC 1100011 SL1000 KSU Expansion Cabinet for PBX system expansion.

The NEC 1100011 is an expansion cabinet (KSU – Key Service Unit) designed for the NEC SL1000 business telephone system. This expansion unit allows organisations to increase the capacity of their existing SL1000 installation by providing additional slots for line cards, extension cards, and other system modules.

The SL1000 KSU Expansion Cabinet connects to the main SL1000 control unit to extend the system’s port capacity, enabling support for additional analogue trunks, digital lines, IP channels, and telephone extensions. This makes it suitable for growing businesses that have outgrown the base unit’s capacity but wish to retain their existing SL1000 infrastructure.

The NEC SL1000 is a legacy PBX platform that was popular among small to medium-sized businesses. While NEC has moved to newer platforms, the SL1000 remains in active use at many sites, and expansion cabinets are sought for maintaining and scaling existing deployments.
