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
and
These slots should be left
vacant; they are reserved for future use with a RCTU
processor upgrade using
cabinets only.
slots
7
and 8 cannot be used with future
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
where each PCB
should be installed.
A PDKU, PEKU, or RSlU must be installed in slot
If
an RSlU is installed in slot 11, then a
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
or, S12 if RSlU is installed in
slot
11.
(Programming can also be performed from
a terminal or
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

can work in any slot. See
Worksheet 2, Table 1-8 in Chapter
Configuration.
The following 2B-channel slots can only support
Speaker OCA, RPCI, or data interface units
(stand-alone, and integrated):
-
S16, S21
-
S26, S31

-
S42, S51

PCBs
installed in
any slot, since these features do not require a
slot!
The following limitations apply to the RDTU T I
interface PCB (see Worksheet 2, Table 1-9 and
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,
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,
and S63, a PCB cannot be inserted
in the next two slots. For example, if the
RDTU is
in
S33, a PCB cannot be installed in
S34 and S35.
If
a 16-channel RDTU is installed in slots S33,
S43,
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
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
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
PGB installation
procedures in this chapter. Configuration instructions
