Analog extensions
Guidelines
• Analog extensions are connected to an AEC/8 card installed in a flexible slot of 
the main unit. A maximum of 8 extensions can be connected to each AEC/8 card.
• Loop resistance not to exceed 100 ohms
.
• Four DTMF signal reception circuits are mounted on the CPC96, CPC288 or 
CPC576 card. If more DTMF circuits are required, add the MFR/8 card to the 
flexible slot.
• AEC/8 cards and MFR/8 cards can be removed and replaced while the system is 
operating. However, because there are no busy lamps for calls on extensions, you 
cannot check the status of these lines. We recommend using paging, etc., before 
removing the cards, to warn users that the lines will be disconnected. See page 5-
1 for details.
• One or more Extension MDF Interface Cards (VB-44611) must be installed to 
support connection of extension lines from the Main Distribution Frame (MDF) 
to the AEC/8 card. Each Extension MDF Interface supports up to three DEC/8 or 
AEC/8 cards (up to 24 extension). See “Extension MDF Interface Card” on page 
5-29 for information on installing the Extension MDF Interface Card.
• Connect analog extensions to analog single line telephones (SLTs) or other 
devices via normal building wiring.
• Table 5-28 shows the maximum numbers of cards and extensions per system type.
Table 5-28.  Maximum cards and analog (and digital) extensions per system
Installation
Note:Prior to installing the Extension Card, make certain you can connect to an 
Extension MDF Interface Card (VB44611) mounted on the side of the cabinet. See 
“Extension MDF Interface Card” on page 5-29 for more information on installing an 
Extension MDF Interface Card.

2.  Referring to Figure 5-15 and Table 5-29 on page 5-41, connect the extension 
card to the MDF Interface Card using supplied sixteen-lead cable.
Note: Labels are supplied with the MDF Interface Card to identify the Flexible 
Slot cable connection. Make certain to attach a label on both ends of the cable 
and at the MDF Interface Card connector.

S-Point ISDN Interface (SBRI)
Guidelines
• S-point ISDN is accommodated by the SBRI/4 card which is installed in the 
flexible slot. Four S-point ISDN lines can be connected to each SBRI/4 card. 
• S-point ISDN is connected to the SBRI/4 card using 8-conductor modular 
connectors. See Figure 5-16 on page 5-43 for the pin configuration of the 8-
conductor modular connectors.
• Setting the rotary switch SW1 of the SBRI/4 enables you to display the status of 
the selected circuits using the LED. The way to set it is the same as that of the 
TBRI/4 card. See Table 5-12 on page 5-20 for details.
• The SBRI/4 card can be attached or detached when the power is turned ON. 
Confirmation during the extension conversation is not possible, therefore 
announcements using paging need to be made when attaching or detaching. See 
page 5-1 for details.
• Table 5-30 shows the maximum number of cards that can be installed in each 
system size.
Table 5-30.  Maximum Number of S-point ISDN Interfaces Per System
Installation
1.  Insert the SBRI/4 card in an available flexible slot.
2.  Connect the 8-conductor modular jack to the S-point ISDN wires from the ISDN 
terminal equipment.
3.  Pass the S-point ISDN wires with 8-conductor modular jack through the wiring 
aperture in the cabinet and connect it to the modular connector on the SBRI/4 
card.

S-point ISDN Primary Rate Interface (PRI)
Guidelines
• The S-point ISDN primary rate interface is accommodated on the PRI/23 card 
which is installed in the flexible slot. You can connect one S-point ISDN primary 
rate interface carrier line to each PRI/23 card.
• By setting the switch and reprogramming, the PRI/23 card can also be set up as an 
T-point ISDN primary rate interface (see page 5-22).
• The S-point ISDN primary rate interface is connected to the PRI/23 card using an 
8-conductor modular jack. See Figure 5-18 on page 5-47 for the pin configuration 
of the 8-conductor modular connectors.
• The PRI/23 card can be set using Dip switch SW2-2 for 8-channel mode or 
Other mode.
Table 5-31 shows the mode settings of the PRI/23 card.
Table 5-31.  Mode Settings of PRI/23 Card
• The DBS 576 can accommodate a maximum of 8 communication channels per 
flexible slot. If you select Other mode, there is a limit of the number of cards 
that can be installed in other slots (see page 4-36.)
• The PRI/23 card can be attached or detached when the power is turned ON by 
setting the maintenance switch (SW3). See page 5-1 for details.
• Table 5-32 shows the maximum number of S-point ISDN primary rate interfaces 
that can be installed in each system size.
