console requires dedicated use of circuit 8 of a
particular PDKU PCB.
13.14 PDIU-DS Configuration.
Refer to Periph-
erals Installation, Chapter 8, for installation proce-
dures for the PDIU-DS. A PDIU-DS can be con-
nected to circuits 1 N 7 on a PDKU; the circuit must
be dedicated to the PDIU-DS.
13.15 PDIU-DI Configuration.
Refer to Telephone
Installation, Chapter 7, and Peripherals Installation,
Chapter 8, for installation procedures for the PDIU-
DI. PDIU-Dls can be equipped with any digital tele-
phone connected to PDKU circuits 1 N 7, but the
quantity is limited (see Table 4-B in Chapter 4).
13.20 PDKU Installation Procedures
13.21
Install the PDKU in accordance with the
following steps:
1) Remove the PCB from its protective packag-
ing.
2) Insert the PDKU into the appropriate slot, and
apply firm, even pressure to ensure proper
mating of connectors.
NOTE:
Ensure the PDKU’s component side is facing
right when installing it in the KSU.
4) After installing the PDKU, gently pull the PCB
outward. If the connectors are properly mated,
a slight resistance will be felt.

14 PCTU (RELEASE 3)
14.01
For PCTU3 (Figure 6-15) installation in-
structions, see Paragraph 3. The PCTU3 PCB has
the same station and CO line capacity and per-
formsthesamefunction as the PCTUl and PCTU2:
It provides centralized control for the KSU. PCTU3
is intended for use with DK56 and DK96; it can also
be used with DK24.
NOTE:
The PI jumper, which is on the PCTU 1 and 2,
is not on the PCTU3. Its function is automatic
with PCTU3 (see Table 6-A).

Paragraph 4. PCTU3 supports the same number of
PEKUs, electronic telephones, and options as
PCTUl and PCTU2.
