OVERVIEW

DSS/BLF

3. Multiple D

term

s cannot use one DSS console.

4. Circuit cards for the DSS are as follows:

• PA-16ELCJ

• PA-DAIG-A (DAI)

• PA-DAIJ-A (DAI)

The previous conditions also apply when a Distributed Access Unit (DAU) is used between the PBX and the

DSS.

6. DSS/BLF

One DSS/BLF console requires 2 consecutive ports on an ELC/DAI card.

When a DSS console is used as a DSS/BLF, be sure to assign and wire the DSS/BLF to a specific LEN whose

level (LV) is an even number (LV = 0, 2, 4, 6). Since a DSS/BLF requires 2 consecutive ports to program the

DSS keys, the port following the designated port, to which the DSS/BLF is wired, must be reserved.

Note:

In Table 1-4, “n” represents 0, 1, 2, 3.
