2.5.4 Analog Station (4/8SLIDB) Daughter Board (Figure 2-24 - Figure 2-25) - P/N 0911042 and 0911046
The 4SLIDB and 8SLIDB daughter boards provide:
● 4 (4SLIDB) 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 4DIOPU blade be used instead (it
supports the analog DID and single line telephone interface functions, such as Off-Premise Extensions).
● Connector for 4/8SLIU blade
● Ring Generator (16Hz/20Hz/25Hz, 75Vrms -28Vdc)
● 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 blades.
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
(remember that the 8SLIU blade will also consume 8 ports).

● 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 blade must be
within the building - no outside cabling is permitted.
