Analog Station (4/8SLIDB) Daughter Board (Figure 2-22 - Figure 2-24)

The 4SLIDB and 8SLIDB daughter boards provide:
●
4 (SLIDB) or 8 (8SLIDB) analog extension ports (used for on-premise analog telephones, fax machines,
and analog modems)
✎
The 4/8SLIDB is not rated for OPX use. It is recommended that a 4/IOPU PCB be used instead (it
supports the analog DID and single line telephone interface functions, such as Off-Premise Extensions).
●
Connector for 4/8SLIU PCB
●
1 extension status LED
●
2 PCB status LEDs
●
Caller ID Sending Ability
●
Message Wait Lamping Ability (110Vdc)
●
Constant current type battery feeding (25mA / -28Vdc)
●
Feeding Polarity Reverse Ability
These daughter boards can be installed on the 4SLIU or 8SLIU PCBs.
●
●
The CN2 (4/8SLIDB) and CN3 (8SLIDB only) connectors each provide connection to 4 analog station ports
and are not polarity sensitive. The SLIDB consumes extension ports ranging between ports 001-256 .

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 SLIU and SLIDB are categorized as TNV2. With this designation, off-
premise wiring is not acceptable. Any cabling to the SLIDB PCB must be
within the building - no outside cabling is permitted.
