nal amplifier for Direct Inward System Access
(DISA) or two-CO line Conferencing.
Standard/Electronic Telephone Interface Unit
(PESU): The PESU PCB offers two standard and
four electronic telephone circuits. Its standard cir-
cuits support the same devices as the KSTU and
PSTU, and its electronic circuits interface with the
same peripherals as the PEKU, except for the
HDSS console. Standard DTMF telephone circuit
operation requires a K4RCU in the Base Key Ser-
vice Unit.
Off-hook Call Announce Upgrade Unit (EOCU):
Electronic telephones connected to PEKU and
PESU PCBs can receive Off-hook Call
Announce—intercom calls over their speaker while
they are on another call—if the PCBs are equipped
with an EOCU. Digital telephones also support this
function but do not require an EOCU type PCB in
the KSU.
CO Line/Digital Telephone Interface Unit (KCDU):
The KCDU provides two CO line circuits and four
digital telephone circuits. The CO line circuits offer
all of the features that the Base Key Service Unit
and the PCOU line circuits provide. The digital tele-
phone circuits can support every peripheral (except
for the DDSS console) that the PDKU and a Base
Key Service Unit digital circuit can support.

TOSHIBA PERIPHERALS

Toshiba offers a number of peripherals that can be
connected to the STRATA DK8 and DK16 systems.

each peripheral, including customer-supplied periph-
erals.
Digital Telephones: The STRATA 2000-series digital
telephones possess the most up-to-date calling
and messaging features. Each telephone has an
attractive design and is available in either charcoal
gray or ash white. The STRATA DK8 can support

the STRATA DK16 can support as many as 16.

other data devices, as well as both internal and
external voice calls.
