Analog Station (4SLIDB-S) Daughter Board (Figure 2-9 - Figure 2-10)
The 4SLIDB-S daughter board provides:
● 4 analog extension ports (used for on-
premise analog telephones, fax machines,
and analog modems)
● Connector for 4SLIU-S PCB
● 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 sensi-
tive. The 4SLIDB-S is installed on the 4SLIU-S
PCB. Up to 2 PCBs can be installed in the system maximum, but this number may be reduced depending on
how many 4SLIU-S PCBs are 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.
