Setting ID No. of Additional Cabinets
Guidelines
• When you add a cabinet to the system, it must be given a cabinet ID number. Each 
cabinet ID number setting is based upon its cabinet position. See Figure 4-23 
through Figure 4-27 for the cabinet positions.
Check that the cabinet ID numbers match the size of the system you are setting 
up.
• Set each cabinet ID number using the ID Rotary Switch as shown in Figure 4-28. 
Refer to the following table for the relationship between rotary switch position 
and Cabinet ID number when setting the ID number.
Important Note:Cabinets with ID rotary switch settings 1 and 2 must be 
cabled together in series. Cabinets with ID rotary switch settings of 3, 4 and 5 
must be cabled together in series. Do not intermix these groups when cabling or 
the system may fail to operate.

Connecting DBS 576 and DBS 96 Systems
Installation
Guidelines
• Before deciding where to install the base cabinet and DBS 96, check the external 
dimensions shown for the base cabinet (page 4-1) and the DBS 96 (DBS 
Installation and Programming Manual) and the areas required for maintenance.
• See Chapter 3 for details of how to install the base cabinet. See the DBS 
Installation and Programming Manual for details of how to install the DBS 96.
• Remove the covers from the base cabinet and DBS 96 (see page 3-2) to connect 
the systems. See the DBS Installation Manual for how to remove the covers from 
the DBS 96.
• Figure 4-29 shows examples of combining base cabinet and DBS 96 systems.
• Only connect to DBS 96 cabinets. The CBLDBS MDF will not fit in a DBS 40 
cabinet. Some DEC ports will not be available in the DBS 72 cabinets.
Figure 4-29. Example combinations of base cabinet and DBS 96CAUTION:
• Turn the power switch and the external breaker OFF, and disconnect the AC 
cable before connecting the systems.
•
 	 
 576 base cabinet and DBS 96 carefully to avoid damage.
• Do not attempt to move the base cabinet or DBS 96 without assistance.
• Do not attempt to connect the base cabinet and DBS 96 system using the 
building block method.
Note:The numbers 1 to 5 are the cabinet ID numbers of the additional cabinets. If you are adding 
two or more cabinets, each added cabinet must have a cabinet ID number (see page 4-27).

Card Installation
Guidelines
• Install the cards in the base cabinet and DBS 96 in the slots indicated under Card 
Installation Position in Chapter 4 (page 4-33).
• In the DBS 96, you can only install DEC cards. You cannot increase the number 
of Trunk Line ports.
• Each additional DBS 96 cabinet increases the number of extension ports by up to 
72.
Installation
See Card Installation in Chapter 3 (page 3-13) for how to install cards in the base 
cabinet.
See the DBS Installation and Programming Manual for details of how to install cards 
in the DBS 96. 
Connecting the Systems
Guidelines
• When expanding a system, use the supplied cables to connect the TSW288/
TSW576 card to the CBLDBS card.
• Use the TSW288 card when the CPC-288 is used. Use the TSW576 card when the 
CPC-576 is used.
Installation
1.  Remove the one or two interface boards from the top of the DBS cabinet and 
retain the screws. CAUTION:
• Turn the power switch and the external broker OFF, and disconnect the 
AC cable before installing the backup battery.
• To prevent EMI interference to TVs, radios, etc., install an EMI filter.

cabinet ID numbers are allocated as shown in Figure 4-23.
Check that the cabinet numbers match the size of system you are setting up.
• Use the rotary switch (SW1) on the CBL card and CBLDBS card to set the 
cabinet ID number.
For details on how to set cabinet ID numbers, see “Setting ID No. of Additional

Card Installation Position
The unit cards are installed in the card slots in the DBS 576 main cabinet. Figure 4-
32 shows the positions in which the cards are installed when the system comprises 
only one main cabinet. Figure 4-33 shows the positions when the main cabinets are 
combined in building-block fashion. Figure 4-34 shows the positions when a DBS 
576 base cabinet is connected to a DBS 96.
