Seller Refurbished NEC Aspire 8 Slot KSU IP1NA-8KSU-A1 (0890000)
The NEC Aspire 0890000 is the 8 Slot KSU (or Key Service Unit) for the Apsire-M phone system. It serves as the main control unit and carrier for the phone system. It has 2 slots for the power supply (not included) and 9 PCB slots for expansion cards. The first slot in the KSU is for the NTCPU card (not included). All remaining slots are universal and can be used with any Aspire expansion cards. The KSU can be floor, wall or rack mounted (not included). The NEC Aspire system can use VoiP to converge your voice and data network and will operate as a hybrid phone system letting you mix IP traffic and standard NEC key system traffic. Like the Aspire S, the Aspire uses peer to peer voip networking meaning that any ip stations will connect directly to each other when in use. Features:
