INSTALLATION-CONFIGURATION
SECTION 400-096-204
SEPTEMBER 1992
•
DDCBs and HDCBs can only be connected to
port numbers 04, 12, 20, and 28. DDCBs can
connect only to digital telephone ports (PDKU),
and HDCBs can interface just with electronic
telephone ports (PEKU and PESU).
•
Always install DDCBs/HDCBs to PDKU/PEKU/
PESU PCBs that are in lower slot numbers than
PEMU PCBs. This is required to maintain align-
ment of Circuit 5 with Port 04, 12, 20, and 28.
•
PCB Slots that support DDCBs and HDCBs do
not require a special code in Program 03.
•
DDCB and HDCB assignments are found in
Programs 77-1, 77-2, and 79.
•
Door phones can be programmed to ring at any
digital and electronic telephone (no limit within
the system). Door phones will not ring standard
telephones, but standard telephone users can
answer door phone calls that are ringing at digital
and electronic telephones by dialing a pickup
access code.
•
Cut W9 on each PEKU and PESU that supports
an HDCB. There are no straps to cut on the
PDKU.
4.30 DSS Console Hardware Configuration
Notes
•
A maximum of four DSS consoles are allowed
per systems with a PCTU (1, 2, 3, or 4) and three
for STRATA DK24 systems with a PCTUS.
•
There are two types of DSS consoles, the digital
DSS console (DDSS console) and the electronic
DSS console (HDSS console). DDSS consoles
operate with PCTU3 and PCTU4 only, while
HDSS consoles can work with all PCTU versions
and the PCTUS.
•
DDSS consoles normally operate in conjunction
with digital telephones. Each DDSS console is
automatically assigned by system software to an
associated digital telephone (on Circuit 1 of the
same PDKU), which in turn is referred to as a
DSS/attendant telephone. A DDSS console,
though, can be reassigned in system program-
ming to be associated with an electronic tele-
phone.
•
HDSS consoles normally operate in conjunction
with electronic telephones. Each HDSS console
is automatically assigned by system software to
an associated electronic telephone (on Circuit 1
of the same PEKU), which in turn is referred to as
a DSS/attendant telephone. An HDSS console,
though, can be reassigned in system program-
ming to be associated with a digital telephone.
•
One PDKU PCB is required for each DDSS
console, and one PEKU is needed for each
HDSS console. The DDSS console connects to
Circuit 8 of a PDKU, and the HDSS console
connects to Circuits 7 and 8 of a PEKU.
•
PDKU/DDSS slots are identified and assigned in
Program 03 with special PCB code 64 (Figure
4-2).
•
PEKU/HDSS slots are identified and assigned in
Program 03 with special PCB codes 23 or 24
(Figure 4-2).
•
DSS consoles and attendant telephones are
automatically assigned as DSS1/ATT1, DSS2/
ATT2, DSS3/ATT3, or DSS4/ATT4, starting with
the lowest DSS slot and continuing, in consecu-
tive order, to the highest DSS slot. But consoles
may be reassigned in Program 28 so that up to
four consoles may be assigned to one tele-
phone.
•
DSS console buttons may be flexibly assigned
(in Program 29) as CO line buttons, DSS (hot
line) buttons, and speed dial buttons.
4.40 Data Interface Unit (DIU) Configuration
Notes
•
The Integrated Data Interface Unit (PDIU-DI or
PDIU-DI2) shares the same wire pair and PDKU
station circuit with the digital telephone to which
it is connected. The PDIU-DI(2) requires a PCTU3
or PCTU4 control PCB. The maximum number
of PDIU-DI(2)s supported by each STRATA DK
system is shown in Table 4-B.
•
The PDIU-DI is a DCE type device that normally
connects to a personal computer serial commu-
nications port or ASCII terminal.
•
The Stand-alone Data Interface Unit (PDIU-DS)
requires a dedicated PDKU station circuit and
one or two pair of wires. (See Section 400-096-
209 for wiring information.) The PDIU-DS re-
quires a PCTU3 or PCTU4 PCB. The maximum
number of PDIU-DSs supported by each STRATA
DK system is shown in Table 4-B.
•
PDIU-DSs may be configured as a DTE or DCE
type device and connect to modems, printers, or
host mainframe computers.
NOTE:
Only Circuits 1 ~ 7 on a PDKU1A support
DIUs, while all circuits, 1 ~ 8, on a PDKU2A
support DIUs. All KSU slots, except for 11 ~ 14
in the DK96, can support DIUs.
