E&M Card (EMC)
6.18
Install each EMC as described below (see RE-
PLACEMENT 
PARTS for the part number). Refer to
Figure 3-36 on page 
3-58 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)
(2)
(3)
Check to see that all components on the card are
seatedsecurely in their sockets and that no pins
are bent.
Check the fuses. There are 24 specially-designed
fuses on each EMC that cannot be replaced in the
field (see page 2-16 for more information).
Depending on the type of E&M trunk to be in-
stalled on each individual EMC circuit, place the
associated jumper plugs in the proper “signaling
type” 
(1,2,4, or 5) and “audio type” (2-wire or
4-wire) positions.NOTE: When setting the jumper plugs, note the
unique ordering of the 
EMC circuits as shown in
Figure 3-36.
(4)Install the RMCs one at a time with the compo-
nentsfacing right. They may be installed in any
slot, and slots may be skipped, if desired. How-
ever, to facilitate installation and programming,
it is recommended that the cards be installed tomatch the default configuration as closely as
possible. (Refer to page 2-13 for information 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 
prograw.
If changing card types (e.g., changing from an
LGC to an EMC), refer to the programming pro-
cedures on page 5-170 and to the information on
pages 3-6 through 3-8.

PLACEMENT PARTS for the part number). Refer to
Figure 3-37 on page 3-60 for an illustration.
NOTE: Like the other station and trunk cards, 
Tl Cardscan be inserted or removed with the system power
turned on, as long as the Tl span is not connected to the
card. However, 
afier inserting a Tl Cad while thepow-
er is on, wait at least ten seconds before inserting any
other card. Also, 
before removing a Tl Cani whilepow-
et is on, first pmss the make-busy switch on the card and
allow the system to “busy out” the 
Tl span, then unplug
the 
Tl span from the connector on the card (see page
2-18 for more information on the make-busy switch).

NOTE: The on-board CSU can now be pur-chase-d directly from Inter-Tel using part
number 440.3004.
Carefully plug the CSU into the large socket
provided on the card (see Figure 3-37).
Place the 
DSX/CSU jumper plug in the CSU
(518) position.
Depending on the distance to the nearest pub-
lic network 
Tl repeater, place the line build-out 
(LBO) attenuation jumper plug in the
appropriate position: 15dB (J21) for O-1599
feet, 
7SdB (J2O) for MOO-2999 feet, or OdB
(J19) for 3000-6000 feet.
If the optional on-board CSU is not installeri,place the 
DSX/CSU jumper plug in the DSX
(517) position.(2) Check the part number of the component
installed in socket U45 (see Figure 3-37).
If the component is labeled with number
LAYWO, a jumper plug must be installed in
location J32.
If the component is labeled with number
LXP602, a jumper plug must be installed in
location J33.
(3)Check to make sure the remaining jumper straps
and plugs are installed in the following locationson the card (see Figure 3-37 for card orienta-
tion):
3l.uEmwPlNSJ14ova pins 2-5
J15over the top two pins
(4)Check to see that all components on the card are
seated securely in their sockets and that no pins
are bent.(5) 
InstalltheTlCsoneatatime(waitingatleastten
seconds between installations if the systempow-
er is on) with the components 
facing right. The
cards may be installed in any slot, and slots may
bc skipped, if desired.
NOTE: When powered up, the system config-
ures the software to match the default card con-figuration (see page 2-13). If the actual cards
installed do not exactly match the default config-
uration, adjustments must be made in databaseprogramming. If changing card types (e.g.,
changing from an LGC to a 
TlC), refer to the
prograxmning procedures on page 5-170 and to
the information on pages 3-6 through 3-8.

Place the handset on hook.Plug one end of the line cord into the 
wall-
mounted modular jack assembly. Plug the other
end into the line cord jack on the bottom of the
keyset.NOTE: To aid in installation/troubleshooting,
display keysets show their station circuit num-
ber, extension number, and assigned user name
for several seconds when power is turned on and
the line cord is 
first plugged in. This display also
appears after a system reset, and whenever the
line cord is removed and replaced while
