8 Aspire Digital Card (8ESIU) — P/N 0891015
8 Analog Station Card (8SLIU) — P/N 0891017
40
The 8ESIU PCB provides:
●
8 digital extension circuits (used for digital telephones, DSS consoles, 1SLTAD adapters,
2PGDAD adapters)
● 2 extension status LEDs (each LED indicates status for 4 extensions - BL1 used for ports 1-4,
BL2 for ports 5-8)
● 1 PCB status LED
●
1 run/block switch
The CN102 and CN103 connectors each provide connection to 4 digital station ports. The PCB
consumes 8 ports, ranging from ports 001-256.
In order to program the system, an 8ESIU or 16ESIU PCB should be installed in slot 1. However,
system programming can be done using the PCPro or WebPro applications or through a VoIP tele-
phone. The ESIU requires one universal slot, with a maximum of 16 PCB's per system.
The 8SLIU PCB provides:
● 8 analog extension ports (used for on-premise analog telephones, fax
machines, and analog modems)
● 8 extension status LEDs
● 1 PCB status LED
● 1 run/block switch
● Connector for 8SLIDB Daughter Board
●
Ring Generator
● 8 SW1 switches which provide constant current type battery feeding (set to either 20mA [default]
or 35mA)
● 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 and CN5 connectors each provide connection to 4 analog station ports and are not polar-
ity sensitive. The 8SLIU is installed in a universal slot, with 15 maximum per system. The PCB
consumes 8 ports, ranging from ports 001-256.
