08.40 CO Line Connection 
08.41 The CO/PBX lines are introduced into 
the STRATA system via 6-wire modular line cords 
(no longer than 25 ft.) connected directly to a jack on the MCOU PCB. Each modular cord 
contains three lines. The opposite end of each cord 
then terminates directly into an RJ-25C jack 
(Figure 24).

MDSU, MOPU and MPLU PCBs 
are routed over 
the top of the PCB shelf and out through the 
rubber grommeted hole on the rear right or left 
side of the MKSU. 
08.43 To install the modular cords, proceed 
as follows: 
a) 
b) 
Loosen the four screws securing the MKSU 
top cover (Figure 25). 
Slide the top cover slightly until the screws 
clear the keyholes, remove the top cover. 
Using a razor blade or sharp knife, cut a 
vertical slit in the rubber grommet on the side 
of the MKSU.

e) Plug each cord into the proper PCB, secure it 
with the cable clamps located on the shelf 
top immediately above each PCB. 
Route the cords across the top of the MKSU 
(Figure 26) and out through the rubber grom- 
met to appropriate connector or MDF block.

not exceed 500 ft. (152.5 m) for 24 AWG wire. 
IMPORTANT: 
When installing DSS cable, do not run 
parallel to and within 3 ft. of an A C power line. Such power lines should be crossed at 
right angles (90’) only. 
08.60 Off Premise Extension / Conventional 
Telephone Connections 
08.61 Off premise/conventional single line 
telephone (OPX) connections are made via a 4- 
wire modular cord to the front of the MOPU PCB. 
One cord is required for each MOPU and serves 
two OPX connections. See Figure 28. 
08.62 r For an OPX telephone to function, 
customer-supplied external DC and ringing power 
supplies are required. Power supply specifications 
are as follows: 
IMPORTANT FCC INFORMATION:

on-premise (that is, using only on-site 
wiring), any power source meeting the

If the telephone is to be used off-premise 
(that is, connected to a line provided by 
the telephone company), its power supply 
must have been tested, and then 
registered with the FCC as being suitable 
for the purpose. Con tact your Toshiba 
supplier for de tails. 08.63 The DC voltage to be used should be 
chosen according to the wire gauge used and the

MOPU #l using standard station wire. If more 
than one MOPU is equipped, the power should 
be “daisy- chained” from MOPU #1 to MOPU 
#2, and, if equipped, to MOPU #3.

ELECTRONIC 
KEY TELEPHOVE INFORMATION 
09.00 General 
09.01 Three different Electronic Key Tele- 
phones (EKTs) may be used in either STRATA 
system. All three EKTs are equipped with four 
permanently dedicated keys and either 10 or 20 
feature keys. Because of the number of these 
feature keys these EKTs are known as a 20-key 
EKT, a 1 O-key EKT and a 1 d-key Busy Lamp 
Field (BLF) EKT. 
09.02 
The 20-key EKT, Figure 31, measures: 
Height: 
4.0 inches 
( 102 mm) 
Width: 
8.8 inches (224 mm) 
Depth: 
9.1 inches (230 mm) 
FIGURE 31-20-key EKT 
and is equipped with 24 line and feature keys in 
addition to its push-button dial pad. In initialized 
mode, seventeen of the keys are utilized for central 
office/PBX lines, one for intercom access, and the 
remaining six keys are used for feature operation. 
System software assignments permit some assign- 
ment variations to the CO/PBX keys to facilitate 
tenant service and private lines, and to allow 
unused keys to be used for automatic dialing. 
09.03 
Software assignment permits the lo-key 
EKT (Figure 321, having the same dimensions 
as the 20-key EKT, to be alternately assigned to 
any station (with the exception of station 17). 
This lo-key EKT has full access to seven CO/PBX 
lines and can receive transferred calls on the 
other I ines.

09.14 Locking tabs secure- the EKT’s base. 
The direction in which the base is attached to 
the EKT determines whether it will be a desk or fi 
wall unit (it is factory-configured as a desk unit). 
Disengage the locking tabs by pushing downward 
on the base (Figure 33). 
, 
FIGURE 32-lo-key EKT 
09.04 An optional lo-key BLF EKT may 
be assigned via software at up to 15 positions 
(stations 10 through 25, except #l7, only). 
This EKT has the same dimensions and key 
features as the 1 O-key. 
09.05 See Program 4XX in Section 100-020- 
300, Programming, for inputting information 
concerning the various EKTs. The system must 
be told which type of EKT is at each station and 
what key assignment is required. (Station 17 
must be equipped with a 20-key EKT.) 
09.06 All EKTs feature modular handset 
cords and are connected to the system via four- 
conductor modular line cords. 
09.10 EKT Wall Mounting 
09.11 An optional handset hanger kit is re- 
quired to convert either type of EKT for wall 
mounting. The EKT may be mounted on a wall 
or any other flat, vertical surface to which the 
base can be secured. 
09.12 When selecting the mounting site, con- 
sider the EKT weight and the additional stresses 
to which the EKT will be subjected. 
09.13 Mounting screws or mollies, appropriate 
for the surface on which the EKT is to be secured, 
must be provided by the installer. 
FIGURE 33--REMOVING EKT BASE 
09.15 Refer to Figure 34, choose which of the 
knockouts are appropriate for the tail cord route, { 
and then cut them. 
FIGURE 34-EKT WIRE ACCESS 
09.16 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.

in the base and secure the EKT (Figure 35).

10 SYSTEM PowER-up ~~JITIAL~ZE 
10.01 STRATA has a list of standard system 
data assignments stored in ROM that can be 
entered anytime by performing the initialize 
sequence outlined below. The system must be 
initialized when it is first installed or whenever 
the 
MCAU PCB is changed. This will allow the 
system to be tested and any faults to. be cor- 
rected before time is spent on programming. 
NOTE: 
Do not initialize if using a preprogrammed, 
battery-protected AMMU. 
10.02 Refer to Figure 37 and verify that 
the battery on the 
AMMU is connected to ensure 
that data changes entered after initialization will 
not be lost due to power failure. 
FIGURE 37-AMMU BATTERY STRAP 
NOTE: 
The SET LED will not function if the AMMU 
battery is not connected. 
10.03 To initialize the system data memory, 
refer to Figures 38 and 39 and perform the fol- 
lowing steps: 
a) Place the power switch on the MPRU PCB 
in the ON position.

Clearing Automatic Dialing 
10.11 
The Automatic Dialing memory will 
contain random numbers when the system is. 
powered up initially. To clear the memory; there- 
fore preventing meaningless numbers from being 
dialed, proceed as follows: 
The use of two or more CRDU PCBs in dif- 
ferent locations will cause several different 
configurations of Automatic Dialing numbers. 
See Table A for further information on 
CRDU locations. 
10.12 To clear the standard Automatic Dial- 
System memory (24 numbers): 
1) Lock in the SET switch on the MCAU: 
l The MCAU LED and MW/FL LED on 
station 17 will go on. 
2) Depress I] key on station 17: 
l SPKR LED will light steadily. 
3) Dial @ R

l SPKR LED will flash continuously. 
4) Depress the following keys:
