the expansion cabinet. Like the universal slots in the
base cabinet, these universal slots are capable of
hosting any of the station, line, and option interface
PCBs (except RSlU which can only be installed in slot
11). The expansion cabinets also provide two slots
labeled "S-7" and "S-8." These slots should be left
vacant; they are reserved for future use with a RCTU
processor upgrade using DKSUE424 cabinets only.
upgrades.
Cabinets are numbered from 1 to 6. The base cabinet
is numbered 1; the first expansion cabinet, number 2;
the second expansion cabinet, number 3; etc.
The following factors should be considered when
installing PCBs:
IMPORTANT !
Use Worksheet 2 in Chapter 1 to determine
the position (cabinet/slot) where each PCB
should be installed.
PDKU or PEKU must be installed in slot 12. The
programming telephone must have 20 feature
buttons and an LCD, and can only interface with
circuit 6 (port 005, station intercom or Primary
Directory Number [PDN] 205) of the PDKU or
PEKU PCB in S11; or, S12 if RSlU is installed in
slot 11. (Programming can also be performed from
a terminal or 280Admin personal computer,
instead of a telephone.) The system, time, date,
and day of week can only be set from an LCD
telephone connected to logical port 000, usually
station intercom or
console.

The following limitations apply to the RDTU T I
interface PCB (see Worksheet 2, Table 1-9 and 1
10 in Chapter l-Configuration):
The RDTU cannot be installed in even
numbered slots.
If a 24-channel (line) RDTU is inserted in slots
S13, S15, S21, S23, S25, S31, S41, S51, or
S61, a PCB cannot be inserted in the next
slot. For example, if the RDTU is in S21, a
PCB cannot be installed in S22.
If a 24-channel RDTU is installed in slots S33,
S43, S53, and S63, a PCB cannot be inserted
in the next two slots. For example, if the
in
RDTU is S33, a PCB cannot be installed in
S34 and S35.
If a 16-channel RDTU is installed in slots S33,
S43, S53, and S63, a PCB cannot be
inserted in the second slot over. For example,
if the RDTU is in S43, a PCB cannot be
placed in S45. However, to allow channels 17-
24 to be used in the future, follow the
guidelines for 24 channels above.
If an 8-channel RDTU is installed, PCBs can
be installed in the next slots and do not have
to be left vacant. Adding channels 9-24 in the
future will not be possible if slots are not left
vacant.

4.2.2 PCB Option Considerations

Strata DK280 PCBs may be configured for a variety of
hardware and software options. Hardware options are
defined as either internal (generally related to optional
PCB subassemblies) or external (related to connection
of peripheral equipment such as background music,
voice mail, etc). Hardware and software options for
each PCB are identified in the individual PCB
installation procedures in this chapter.

PCB Hardware Options
Some PCBs must be configured for hardware options
prior to installation of the PCB in the KSU.
Configuration instructions for internal hardware
options are provided in the fndividual PGB installation
procedures in this chapter. Configuration instructions
