3 STATION CONSIDERATIONS 3.10 Telephone Circuit (Port) Types
3.00 For configuration purposes, a station can be
considered as any device which is connected to a
dedicated telephone circuit. Although the words
“telephone” and “station” are often used synony-
mously and interchangeably in STRATA DK8/
DK16 documentation, devices other than tele-
phones-such as Stand-alone Data Interface un.its
(PDIU-DSs)-should also be considered as sta-
tions when configuring a system, because they
require a dedicated telephone circuit. A station
apparatus overview is shown in Table 3-G (for
STRATA DK8) and Table 3-H (for STRATA DK16).
3.11 There are three types of telephone circuits to
which stations can be connected: digital telephone
circuits, electronic telephone circuits, and stan-
dard telephone circuits. All three types of circuits
are available with the STRATA DK16. The STRATA
DK8 does not support electronic telephone cir-
cuits.
3.20 Digital Telephone Circuit Connections
3.21 The STRATA DK8 Key Service Unit provides
four digital telephone circuits. The QCDU PCB
provides two.
