Keyset Cards (DKSCs)
6.13Each DKSC comes equipped with one Digital
Signal 
ProcessoI(DSP) for shared speakerphone re-
sources. If desired, a second DSP can be installed to pro-vide additional speakerphone resources. Refer to
SPEClFICATIONS, page 2-12, for more information.
6.14Install the cards as described below. The part
number is listed in REPLACEMENT Pm. Refer to
Figure 3-30 on page 3-48 for an illustration.NOTE: 
Wheri inserting or removing the RCPU Card,
the system power must be turned off to prevent damage
to the card. However, station and 
truuk cards can be in-
serted or removed with power on. (After inserting a 
Tl
Card, wait ten seconds before inserting any other card.)
(1)
If the optional DSP is to be instalkd:
a.Place each DKSC on a clean, flat, anti-static,
non-conductive surface.
b: Carefully install the optional DSP in socket
U38. (See Figure 3-30 on page 3-48.) The
notch (or smaR dot in the corner) indicatingpin 1 on each DSP must match the notch of
the outline silkscreened on the card.
(2)Check to see that all components on the cards are
seated securely 
in their sockets and that no pins
are bent.
(3)Install the DKSCs one at a time in the slots to be
used for digital 
keysets. The component sides of
the cards must 
face right. Any type of card may
be installed in any slot, and slots may be skipped,
if desired. However, to facilitate installation and
programming, it is recommended that the cards
be installed to match the default configuration as
closely as possible. (Refer to page 2-13 for infor-
mation on the default configuration.)
NOTE: When powered up, the system config-
ures the software to match the default card con-figuration. If the actual cards installed do not
exactly match the default configuration, adjust-
ments must be made in database programming.
Circuit 1.1 is preset for the primary attendant (a
KSC circuit). If changing card types (e.g.,
changing from an SLC to a DKSC), refer to the
programming procedures on page 
5-170 and to
the information on pages 3-6 to 3-8.

Keyset Cards (KSCs and KSC-Ds)
6.15Install the cards as described below. Part num-bers are listed in REPLACEMENT PARTS. Refer to
Figure 3-31 on page 3-50 for an illustration.
NOTE: When inserting or removing the RCPU Card,
the system power must be turned off to prevent damage
to the card. However, station and trunk cards can be in-
serted or removed with power on. (After inserting a 
Tl
Card, wait ten seconds before inserting any other card.)
(1)
For all KSCs that will have any &line IMXALM
kqtiinstalld Check the part number and la-bel silkscreened on the card. To install 
g-line
IMXAIM keysets rwo to a cinzuit, the new-dual-
circuit” version 
Keyset Card (KSC-D) must be
used (see 
RF,PLACEMENT PARTS for the part
number). To install 
8-line IMX AIM keysets one
to a circuit, either the RSC or the KSC-D can be
used.
(2)Check to see that all components on the cards are
seated securely in their sockets and that no pins
are bent.
(3)Check the fuses. Some KSCs have a 2A, 25OV,AGC 2 (fast-acting) fuse. KSC-Ds and newer
version KSCs have eight self-correcting thermis-
tors (one for each circuit) instead of the fuse. If a
short circuit causes a thermistor to open, it will
automatically close when the short is removed.
(4)Jnstall the KSCa and/or KSC-Ds one at a time inthe slots to be used for analog 
keyset, analog
DSS/BLF Unit, and Attendant Computer Con-
sole connections. The component sides of the
cards must 
face right. Any type of card may be
installed in any slot, and slots may be skipped, ifdesired. However, to facilitate installation and
prograxmning, it is recommended that the cards
be installed to match the default configuration as
closely as possible. (Refer to page 2-13 for infor-
mation on the default 
configuration.)
NOTE: When powered up, the system config-
ures the software to match the default card con-figuration. If the actual cards installed do not
exactly match the default configuration, adjust-
ments must be made in database programming
Circuit 1.1 is preset for the primary attendant (aKSC circuit). If changing card types (e.g.,
changing from an SLC to a KSC), refer to the
programming procedures on page 
5-170 and to

Figures 3-32 and 3-33 on pages 3-52 and 3-53 for illus-
trations.
NOTE: When inserting or removing the RCPU Card,

For each circuit on all IDCs: On older-version
IDCs, make sure the AC ENABLE jumper strap
is installed (either on the card or at the block) for
off-premises extensions and AC-ringing on-pre-
mises equipment. The strap must be removed for
DID trunks and 
DC-ringing on-premises equip
ment. Newer-version 
IDCs have a 3-pin RING
SELECT jumper strap that must be placed in the
AC/OPX position (over the bottom two pins) or
the DC/DID position (over the top two pins).
NOTE: When setting the jumper straps on either
version card, note the unique ordering of the IDC
circuits as shown in Figure 3-33 on page 3-53.
Check to see that all components on the cards are
seated securely in their sockets and that no pins
are bent.
Check the fuses:l Some 
SLCs have a fuse that cannot be re-
placed in the field (see page 2-12 for more in-formation). Newer version 
SLCa have a
self-correcting thermistor instead of the fuse.l Each IDC has 16 specially designed fuses
that camtot be replaced in the field (see page
2-15 for more information).(4)
Install the cards one at a time. Any type of cardmay be installed in any slot, and slots may be
skipped, if desired. However, to facilitate instal-
lation and programming, it is recommended that
the cards be installed to match the default config-uration as closely as possible. (Refer to page
2-13 for information on the default 
uxrfigura-tion.) .
NOTE: When powered up, the system config-
ures the software to match the default card con-figuration. If the actual cards installed do not
exactly match the default configuration, adjust-
ments must be made in database programming.
Circuit 1.1 is preset for the primary attendant (aKSC circuit). If changing card types (e.g.,
changing from a KSC to an SLC), refer to the
programming procedures on page 5-170 and to
the information on pages 3-6 to 3-8.
For SLCs: Install SLCs in the slots to be used
for AC-ringing single-line set and AC play-back device connections. The component
sides of the cards must face right.
For 
IDCs: Install IDCs in the slots to be used
for DID trunk, off-premises extension, sing-
le-line set, and playback device connections.
The 
component sides of the cards must face
right.
NOTE: lf installing off-premises extensions,refer to page 3-30 before installing any
IDCS.

(see REPLACEMENT PARTS for the part number). Re-
fer to Figures 3-34 and 3-35 on pages 3-55 and 3-56 for
an illustration.
NOTE: When inserting or removing the RCPU Card,
the system power must be turned off to prevent damage
to the card. However, station and trunk cards can be in-
serted or removed with Power on. (After inserting a

Check to see that all 
compcnents on the card are
seated securely in their sockets and that no pins
are bent.
Check the fuses. There are 16 speciallydesigned
fuses on each LGC and LSC that 
cannot be re-
placed in the field (see page 2-14 for more infor-
mation).
For LGCs Only: Depending on the type of CO
trunk to be installed on each individual LGC cir-
cuit, place the associated two jumper straps in
the Proper loop start 
(LS) or ground start (GS)
position.NOTE: When setting the straps, note the unique
ordering of the LGC circuits as shown in Figure
3-34. For each LGC circuit, borh straps must be
in the 
proPer (LS or GS) Position. Ifthe strap set-
tings are mixed, or if one or both of the 
straPs is
missing, the circuit will not function properly.
Install the 
LGCs and LSCs one at a time with the
components facing right. They may be installed
in any slot, and slots may be skipped, if desired.
However, to facilitate installation and program-ming, it is recommended that the cards be in-
stalled to match the default configuration as
closely as Possible. (Refer to page 2-13 for infor-
mation on the default configuration.)
NOTE: When Powered up, the system config-
ures the software to match the default card con-figuration. If the actual cards installed do not
exactly match the default configuration, adjust-
ments must be made in database Programming.
If changing card types (e.g., changing from an
SLC to an LGC), refer to the programming pro-
cedures on page 5-170 and to the information on
pages 3-6 through 3-8.
