							TEND”option refers to the use of “loop
extenders” on long CO lines.
If a battery boost is used on the trunk
line, select“EXTEND’‘-otherwise, “NO
EXTEND” should be selected.d) The LOOP START “NORMAL/REVERSE”
option refers to the system’s ability to detect
a pre-ring supervision signal in the form of a
battery polarity reversal on the CO line TIP
& RING.
If “‘NORMAL” is selected, the system
will not be sensitive to CO line polarity.
If “REVERSE” is selected, the CO circuit
will be “made busy” when the CO reverses
polarity prior to ringing on an incoming call.

amphenol-type connectors are attached to the connector
panel of the DCEC and secured with the connector
locking bar (Figure 23). Plastic cable clamps are
provided along the base of the DCEC to secure the
cables. The opposite ends of the cables are then
terminated on “66’‘-type quickconnect terminal
blocks. Split blocks with bridging clips should
be used to allow for fault isolation. Connect each
cable from the DCEC to one side of the block,
external equipment cables to the other side, and
use bridging clips to make the connections.

1A keyboard/printer terminal (Texas
Instruments Model 
743/745 or equivalent) is
required to communicate with the PERCEPTION
system. (See Section 100-I 00-300, Programming,
for operating details.)
The terminal is connected to the system
’ via a female-type RS 232C connector (labeled
TTY) located on the connector panel on the
lower rear of the DCEC.
In addition to the TTY connector,
DEM connector is provided. By attaching
a customer-provided “answer only” modem,
all functions normally performed by the local
terminal can be performed from a remote location.
The TTY and MOM ports can operate
peedof 300 or 1200s, and utilize a stan-
dard 7-level 
ASCII code with one start bit, one
stop bit and one parity bit. The system transmits
even parity and ignores the parity bit on the
receive side. The speed is selected by a push-on/
-off switch located o
the front of the 
DPEUThe associated LE
is on when 1200 bps
is selected.The speed selection is made simultan-
eously for the TTY and MODEM ports. These
two ports are wired in a logical “OR” fashion
and cannot be used at the same time. One must
be “open”.
The pin assignments of the TTY and
modem connectors are:

and is equipped with 14 line and feature keys in
addition to its push-button dial pad. All 
10 keys
in the vertical row are equipped with 
LEDs and
are available for flexible assignment (Figure 29).
Normally one key in the vertical row is designated
as the DN key, while the remaining keys may have
several different designations depending upon
programming. The horizontal row of keys on
each EKT has fixed assignments. Looking from
left to right, they are 
ISPKR/ , j , jCONFl and
IHOLD/ . Of the four, only the speaker key is
equipped with an in-use LED. 
						

							2The XI-key EKT (Figure
same overall dimensions as the standard EKT, and
is installed in exactly the same manner. It provides
an additional 
10 flexible assignment keys in the

and is connected to the system via a &conductor
modular line cord.

1An optional handsetanger kit is re-
quired to convert either typefEKT for wall
mounting. The EKT may be mounted on a wall
or any other flat, vertical surface to which the
base can be secured.
2When selecting the mounting site, con-
sider the EKT weight and the additional stresses
to which the mounting will be subjected.
3Mounting screws or mollies, appropriate
for the surface on which the telephone is to be
secured, must be provided by the installer.
Locking tabs secure the base to the
EKT. The direction in which the base is attached
to the EKT determines whether it will be used
as a desk unit or wall unit (it is factory-configured
as a desk unit). Disengage the locking tabs by
pushing downward on the base (Figure 
31).
5Refer to Figure 32, choose which of
the knockouts are appropriate for the tail cord
route, and then cut them.Secure the base to the desired wall
site. Use a spirit level and make certain the top
of the base is level and that the deeper portion
is down.
Route the tail cord through the holes
in the base and secure the EKT (Figure 
33).

cord is recommended for use with wall-mounted
