8.10 Electronic Telephones
8.11 Four 6500-series Electronic Telephones (the
EKT6510-S, EKT6510-H, EKT6520-H, and
EKT6520-SD) are compatible with the STRATA
DK systems. These telephones can be used to
access a number of standard, useful features and
have internal connectors which allow them to be
upgraded for more features, such as Off-hook Call
Announce. (See Digital and Electronic Telephone
Upgrade Options later in this chapter.) All elec-
tronic telephones come with a standard handset
and, in most cases, can be connected to the
system with a two-pair modular line cord. See the
General Description for a more complete descrip-
tion of these phones.
NOTE:
All electronic telephones compatible with the
analog STRATA/STRATA
systems are also compatible with the STRATA
DK systems and vice versa. However, some
features or volume levels may vary.
8.20 Digital and Electronic Telephone Up-
grade Options
8.21 All digital and electronic telephones are hear-
ing aid-compatible and may be upgraded with Off-
hook Call Announce, Loud Ringing Bell and head-
set capability. Digital telephones may also be
upgraded with data calling capability.
Integrated Data Interface Unit (PDIU-DI, PDIU-
DI2): Digital telephones may be upgraded with
an integrated data interface unit (PDIU-DI or
PDIU-DI2) to receive and transmit simultaneous
voice and data; data and voice calls can be
made independently of each other. Available
only with Release 3 and higher software, the
PDIU-DI/PDIU-DI2 is easily installed, replacing
the normal digital telephone base. The PDIU-
DI2 can be mounted in a 2000-series Digital
Telephone, while the PDIU-DI can be mounted
in a 1000-series Digital Telephone.

INSTALLATION-SYSTEM DESCRIPTION
1. The PDIU-DI will function with all slots,
except slots 11 ~ 14 in DK96.
2. PDKU1A Circuits 1 ~ 7 only can support
PDIU-DIs/PDIU-DI2s, while all PDKU2A
circuits, 1 ~ 8, can support PDIU-DIs/
PDIU-DI2s.
Off-hook Call Announce Upgrade (DVSU,
HVSU2): A DVSU subassembly can be installed
in digital telephones and the HVSU2 in elec-
tronic telephones, enabling these phones to
receive Off-hook Call Announce (OCA) calls.
Electronic telephones can also be equipped
with the older HVSU and HVSI subassemblies
for OCA reception.
NOTE:
Only those telephones programmed to re-
ceive OCA announcements require the OCA
upgrade. A telephone does not have to be
equipped with an OCA upgrade to make an
OCA call.
Loud Ringing Bell/Headset Upgrade (HHEU):
An HHEU can be installed in digital and elec-
tronic telephones to provide a Loud Ringing Bell
interface and a modular headset jack.
•
For the Loud Ringing Bell feature, an exter-
nal speaker/amplifier called the HESB can
be connected to the HHEU in the telephone
to mimic the ring whenever the telephone is
called.
•
Most standard headsets are compatible with
the HHEU jack.
8.30 Direct Station Selection (DSS) Consoles
8.31 The DSS console is an optional dedicated
answering station normally used on systems with
a heavy volume of incoming calls. Each system
can support as many as four DSS consoles—the
DK24, however, can only support three if equipped
with a PCTUS. Each DSS console must be asso-
ciated with just one telephone, but a telephone can
be associated with as many as four DSS consoles.
DSS consoles can be connected to designated
circuits on the PDKU (DDSS consoles) and PEKU
(HDSS consoles) PCBs. For more information on
DSS console features, see the General Descrip-
tion.
