Analog Station (4SLIU-S) PCB (Figure 2-8)

The 4SLIU-S 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-S Daughter Board
●
Ring Generator
● Message Wait Lamping Ability
The CN3 connector provides connection to 4 analog station ports and are not polarity sensitive. The
4SLIU-S 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-S PCBs which can be installed. If 3 4SLIU-S PCBs are
installed, only 1 4SLIDB-S can be installed. If 4SLIU-S PCBs are installed, the 4SLIDB-S can not be used.
There must be enough available ports in order for the Aspire system to recognize an 4SLIU-S PCB.

The 4SLIU-S is not rated for OPX use. It is recommended that a 2DIOPU-S PCB be used instead (it
supports analog DID and single line telephone interface functions, such as Off-Premise Extensions).
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.
