EXPANSION CARDS
To expand the DCS to more than a single cabi-
net system, expansion cards are required.
These cards provide the high speed digital link
pathways that enable the KSU to communicate
with the expansion cabinets. There are three
types available and are described below.
EXPANSION A
This card is installed in slot 7 of the KSU and
reduces the available universal card slots to
six. It is only needed if the system is to be ex-
panded. See Figure 2–4.
The Expansion A card contains the following:
l HDLC connections for two expansion cabinets
l Additional eight DSPs
l LED status indicator
EXPANSION A1
This card is installed in slot 7 of the KSU and
reduces the available universal card slots to
six. It is needed if the system is to be expanded
and is also required for Caller ID features. See
Figure 2–4.
The Expansion A1 card contains the following:
l HDLC connections for two expansion cabinets
l Additional eight DSPs
l LED status indicator
