NEC Aspire IP1WW-32ESIU-PR2 32 Port Digital Station Card 0891058
Digital Station (8/16/32ESIU) PCB
The ESIU PCB provides:
? 8 (8ESIU), 16 (16ESIU), OR 32 (32ESIU) digital extension circuits (used for digital telephones, DSS consoles, 1SLTAD adapters, 2PGDAD adapters)
? 2 (8ESIU), 4 (16ESIU), OR 8 (32ESIU) extension status LEDs (each LED indicates status for 4 extensions - BL1 used for ports 1-4, BL2 for ports 5-8, BL3 for ports 9-12, BL4 for ports 13-16, etc.).
? 1 PCB status LED
? 1 run/block switch
Note: Any cabling to the ESIU PCB must be within the building - no outside cabling is permitted.
With the 32ESIU PCB
THE 32ESIU PCB has four connectors (CN2, CN3, CN4, and CN5). Each connector provides 2 modular
jacks which are used to connect up to 4 digital station ports.
Using the 32ESIU PCB
This card requires system software 4.00 or higher and will work with any version of NTCPU PAL chip - Basic NTCPU (P/N 0891002), Basic NTCPU with Feature Upgrade PAL (P/N 0891039), or the Enhanced NTCPU (P/N 0891038).
When installing the 32ESIU PCB, the system will assign the next 32 consecutive ports. Keep this in mind when replacing two 16ESIU PCBs with a 32ESIU PCB. Both 16ESIU slots should be deleted in Program 90-05, otherwise, the system will assign new station ports to the PCB.
