RESERVE POWER TIME 
TYPICAL RESERVE POWER DURATION ESTIMATES * 
Time is estimated with the following considerations: 
1. Batteries have full charge at start of operation. 
2. Batteries (2) are connected in series. 
8. Batteries are 12VDC, rated at 80 amp/hours each. 
4. System is operating at full load traffic with LCD phones. 
5. Batteries used for this test are 
gel-Cell and maintenance-free. Reserve duration will vary &pending 
upon battery type, age, and manufacturer. These figures should only be used as an estimate. 
Each digital telephone also features a 
standard modular handset cord and is connected 
to the system with a single-pair modular line cord 
which can transmit and receive simultaneous 
voice and data.

can also be upgraded with off-hook call 
anounce, loud ringing bell, and headset inter- 
face capability. 
l Simultaneous Voice and Data: Digital 
telephones may be upgraded with an inte- 
grated data interface unit (PDIU-DI) to 
receive and transmit simultaneous voice 
and data; data and voice calls can be 
made independently of each other. The 
PDIU-DI (Figure 5) is easily installed, 
replacing the usual digital telephone base. 
Asynchronous data devices, such as per- 
sonal computers and terminals, can be 
connected to the standard RS-232 connec- 
tor of the PDIU-DI. Station users are able 
to transmit and receive RS-232 data over 
the PDIU-DI-equipped digital telephone’s 
single twisted wire pair. 2B+D technology 
enables the digital telephone and the 
PDIU-DI to share the same wire pair and 
station port (see Table D). 
FIGURE 54NTEGRATED DATA INTERFACE UNIT 
(PDIU-DI) 
NOTE: 
The PDIU-DI will function with all slots, 
except slots 11 w 14 in DK96. 
l Off-hook Call Announce Upgrade: If 
equipped with an off-hook call announce 
(OCA) upgrade assembly, each digital tele- 
phone may receive intercom calls when 
the handset is off-hook. 
l The OCA upgrade assembly for digital 
t Requires Release 3 software 
telephones is a small printed circuit 
board, DVSU, which installs inside the 
telephone base-with plug-in cormectors. 
l Only those telephones programmed to 
receive OCA announcements require a 
DVSU. 
l An extra wire pair is not required for 
digital telephones to receive or originate 
OCA, and no other subassemblies are 
required for the Digital Telephone 
Interface PCB (PDKU). 
l Loud Ringing Bell/Headset Upgrade: 
Each digital telephone may also be 
upgraded to provide a loud ringing bell 
interface and a modular headset interface. 
To accomplish this, an upgrade assembly 
consisting of a small PCB (HHEU) installs 
inside the phone with a plug-in connector. 
The loud ringing bell and headset options 
are available simultaneously on a digital 
telephone. 
l Loud Ringing Bell: An external speak- 
er (HESB) can be directly connected to 
the upgraded phone. When the phone e 
rings, the HESB produces a loud tone 
that mimics the phone’s ring. On voice 
first intercom calls, the HESB amplifies 
the caller’s voice announcement. See 
the External Speaker option. 
l Headset: Most standard headsets plug 
into the HHEU jack and are compatible 
with the digital telephone. 
Option Combinations: A digital telephone may 
use most of the .available upgrade options 
simultaneously. For example, the same station 
may be upgraded with a digital DSS console, 
OCA, loud ringing bell, and headset. Digital 
telephones upgraded with the PDIU-DI cannot 
be wall mounted or upgraded with the loud 
ringing bell, headset, or OCA interface, but 
can be connected with digital DSS consoles. 
Digital Direct Station Selection Consolet: The 
Digital Direct Station Selection (DDSS) con- 
sole is an optional, dedicated answering sta- 
tion incorporating 
a’busy lainp field (Figure 6), 
( 
and can only be used with a digital telephone. 
-6-  
						

							It is normally used on systems with a heavy 
volume of incoming calls. A DDSS console 
may be used with any digital station connected 
to the first circuit on the digital telephone inter- 
face PCB (PDKU). Up to four DDSS consoles 
can be supported with a PCTU3 PCB. 
0 
0 
0 DDSS consoles are equipped with auto- 
matic line hold, and voice or tone signaling 
capability. The consoles have 60 flexible 
buttons, each with an associated LED (the 
DDSS button LEDs will light red or green 
depending on the button function). Each 
flexible button can be assigned one of the 
following functions: 
All call page (pre-assigned) 
CO line appearance 
Direct station selection with busy LED 
Night transfer (pre-assigned tenant 1 or 
tenant 2, if necessary) 
Speed dial 
Each DDSS console requires one station 
port on a PDKU, always the eighth circuit. 
A DDSS console must be assigned to a 
particular station when the system configu- 
ration is defined in programming. All four 
DDSS consoles can be assigned to one 
station, or four different DDSS consoles 
may be assigned to four different stations 
(or any intermediate combination). The 
same DDSS console may not be assigned 
to more than one station.

Electronic Telephones 
- Four different models of 6500-series electronic 
telephones are available. The phones are en- 
closed in a stylish, impact-resistant case (either 
ash white or charcoal gray) with a matte finish, 
and blend easily into any progressive office envi- 
ronment. Toshiba electronic telephones that are 
compatible with the analog STRATA/STRATA, 
key telephone systems are also compatible with 
the STRATA DK systems. However, some fea- 
tures may vary (e.g. LCD and busy lamp field 
telephones). 
All 6500-series electronic telephones and DSS 
consoles have the same dimensions: 
Height: 3.6 in (92 mm) 
Width: 7.0 in (178 mm) 
Length: 9.0 in (229 mm) 
In standard form all electronic telephones may 
be wall mounted without additional equipment, 
and they are also hearing aid compatible. 
Each electronic telephone also features a 
standard modular handset cord, and is connect- 
ed to the system with a 2-pair modular line cord. 
Various upgrade options, such as the off-hook 
call announce and loud ringing bell upgrade 
assemblies, require special wiring. A 3-pair mod- 
ular line cord is required for off-hook call 
announce, and a custom external speaker cable 
is required for the loud ringing bell.

ELECTRONIC TELEPHONE 
Electronic Telephone Upgrade Options: All 
electronic telephones may be upgraded with 
off-hook call announce, loud ringing bell, and 
headset capability. 
l Off-hook Call Announce Upgrade: Each 
electronic telephone may be upgraded to 
receive intercom calls when the handset is 
off-hook by installing an off-hook call 
announce upgrade assembly. 
l The assembly consists of two PCBs, 
HVSU and HVSI, which install inside the 
telephone base with plug-in connectors. 
l Only those telephones programmed to 
receive OCA announcements require 
the OCA upgrade. 
l Each station PCB (PEKU or PESU) that 
supports electronic telephones with 
OCA capability must be equipped with 
an EOCU subassembly. 
l Loud Ringing Bell/Headset Upgrade: 
Each electronic telephone may also be 
upgraded to provide a loud ringing bell 
interface and a modular headset interface. 
To accomplish this, an upgrade assembly 
consisting of a small PCB (HHEU) installs 
inside the phone with a plug-in connector. 
l An external speaker (HESB) can be 
directly connected to the upgraded 
phone. When-the phone rings, the 
HESB produces a loud tone that mimics  
						

							the phone’s ring. On voice first intercom 
calls, the HESB amplifies the caller’s 
voice announcement. See the External 
Speaker option. 
l Most standard headsets plug into the 
HHEU jack and are compatible with the 
electronic telephone. 
l An electronic telephone may use all avail- 
able upgrade options simultaneously. For 
example, the same station may be upgrad- 
ed with a DSS console, OCA, a loud ring- 
ing bell, and a headset. 
Direct Station Selection Console: The Direct 
Station Selection (DSS) console is an optional, 
dedicated answering station incorporating a 
busy lamp field (Figure 10). It is normally used 
on systems with a heavy volume of incoming 
calls. A DSS console may be used with any 
station connected to the first circuit on a PEKU 
PCB. Up to four DSS consoles can be sup- 
ported with a PCTU PCB, and up to three with 
a PCTUS PCB. 
DSS consoles are equipped with automatic 
line hold, and voice or tone signaling capa- 
bility. The consoles have 60 flexible but- 
tons, each with an associated LED. Each 
flexible button can be assigned one of the 
following functions: 
l All call page (pre-assigned) 
0 CO line appearance 
l Direct station selection with busy LED 
l Night transfer (pre-assigned tenant 1 or 
tenant 2, if necessary) 
l Speed dial 
Each DSS console requires two station 
ports (circuits 7 and 8) on an electronic 
telephone interface PCB (PEKU). Only one 
DSS console may be installed on a partic- 
ular PEKU. 
A D$S console must be assigned to a par- 
ticular station when the system configura- 
tion is defined in programming. All four 
DSS consoles can be assigned to one sta- 
tion, or four different DSS consoles may be 
assigned to four different stations (or any 
intermediate combination). The same DSS 
console may not be assigned to more than 
one station. STRATA DK

Table 0). 
Door Phone: In one of its most popular applica- 
tions, the door phone (Figure 12) mounts out- 
side a building, next to a locked door whose 
entry requires screening. An individual located 
outside the building who wants to speak with 
someone inside simply presses the button on 
the door phone. A distinctive tone will then 
sound over the speakers of the digital and/or 
electronic telephones defined to do so through 
system programming. Any digital or electronic 
telephone user can answer and converse with 
the individual at the door phone. If the system 
is properly configured, the user can allow entry 
using a door lock button on the digital or elec- 
tronic telephone. 
l A door phone also functions as a sound 
monitor. Any telephone can call the door 
phone and listen to sounds within its 
immediate area. 
l Up to twelve door phones can be support- 
FlGURE12-DOORPHONE ed with a PCTU, up to nine with a PCTUS. 
A door phone/lock control unit 
- (HDCB-Figure 13) must be installed to 
support up to three door phones (or two 
door phones and one door lock control). 
Each HDCB requires one station port on 
an electronic telephone interface PCB 
(PEKU or PESU). Only one HDCB can be 
installed on a particular PEKU or PESU. 
FlGURE13-DOORPHONE/LOCK 
CONTROLUNlT(HDCB) 
NOTE: 
The PDKU cannot support an HDCB. 
l Door lock control requires an optional 
interface PCB (PIOU, PEPU, or PIOUS) 
and/or an HDCB. Up to five door lock con- 
trols can be installed, but each door lock 
controlled by an HDCB reduces the door 
phone capacity on that HDCB from three 
to two. 
External Speaker: The HESB external speaker 
unit is a 6-inch, 3-watt speaker with a built-in 
amplifier (Figure 14). A +12 VDC power supply 
(HACU-120) is included with each external 
speaker. It connects to the back panel with an 
8-foot cord and plugs into a 117VAC, 60 Hz 
outlet. The HESB has three applications: 
l Amplified Paging Speaker: Allows the 
HESB to be used as a paging speaker, 
reducing the need for other manufacturers’ 
paging equipment.

l Amplified Talkback Speaker: When used in conjunction with external page, an 
HESB can be installed as a talkback 
device. The HESB is connected to the 
door phone, which is used as a micro- 
phone to provide talkback capability. 
l Loud Ringing Bell: Allows the voice/tone 
of a paging/ringing call to any digital tele- 
phone or 6500-series electronic tele- 
phone to be amplified. When an HESB is 
connected as a loud ringing bell, an 
HHEU upgrade assembly must be 
installed in the digital or electronic tele- 
phone’s base. See the loud ringing 
bell/headset telephone upgrade in the last 
section. An external speaker cable 
(HESC-65 for electronic telephones; 
HESC-65A for digital telephones) con- 
nects the station to the speaker.
