Aspire S Station PCBs

8 Aspire Digital Card (8ESIU-S) — P/N 0891051
4 Analog Station Card (4SLIU-S) — P/N 0891048
20
The 8ESIU PCB provides:
●
8 digital extension circuits (used for digital telephones, DSS consoles,
1SLTAD adapters, 2PGDAD adapters)
● 1 extension status LED (indicates status for 4 extensions)
● 1 PCB status LED
The CN3 and CN4 connectors each provide connection to 4 digital station
ports. The ESIU requires one universal slot, with a maximum of 2 PCB's
per system. Note that this PCB can not be installed in slot 7 or 8.
The 8ESIU consumes 8 ports ranging between ports 001-26. There must be
enough available ports in order for the Aspire system to recognize an
8ESIU PCB.
The 4SLIU PCB provides:
● 4 analog extension ports (used for on-premise analog telephones, fax
machines, and analog modems)
● 4 extension status LEDs
● 1 PCB status LED
● Connector for 4SLIDB Daughter Board
● Ring Generator
● Message Wait Lamping Ability
Note: When connecting a fax machine or analog modem, make
sure to set Program 15-03-03 to '1' (special terminal) to avoid communication problems.
The CN3 connector provides connection to 4 analog station ports and are not polarity sensitive. The
4SLIU is installed in a universal slot with a maximum number of 4 PCBs per system. This number
of PCBs installed will reduce the number of 4SLIDB PCBs which can be installed. If 3 4SLIU
PCBs are installed, only 1 4SLIDB can be installed. If 4SLIU PCBs are installed, the 4SLIDB can
not be used. There must be enough available ports in order for the Aspire system to recognize an
4SLIU PCB.
