Use the software program 280Quote to provide easx fast, automated configuration. This
runs on an lBM compatible 486 PC, or higher, witha hard drive.
If the above softwareis not available,
use all the Worksheetsin Chapter I - Configuration.
Important Installation Notes:
Place the RCTU jumper plug(s) into battery position; otherwise, all programmed data will
be lost upon power down. Battery jumper plugs are on: RCTUA, RCTUB, RCTUBA3,
RCTUC, and RCTUD3PCBs.
InstallRCCS PCBs on RCTU PCBsas required.
InstallPDKU, PEKU, or RSlU in slot 11.
- and/or -
If an RSlU is installed in slot 11, installa PDKUor PEKU in slot 12.
Startingwith the lowest empty slot (S12 or S13), installall station, attendant console, loop
start, ground start, and RCIU/RCIS PCBs from lower to higher numbered slots (left to
right). Do not leave empty slots except when installing RDTU PCBs when required per
Tables 1
- 9and 1-1 0 of Chapter 1 - Configuration.
After all station, attendant console, and ground/loop start line, and RCIU/RCIS PCBs are
*
installed, installall DID and tie line PCBsstartingfromthe first numberedempty slot to the
highest needed
(in left to right order). Do not leave empty slots except when installing
RDTU PCBs per Tables 11
- 1, 11 - 2, and 11 - 3 of Chapter 11-T1.
InstallPIOU, PIOUS, PEPU, or RSSU in any convenientvacant slot.
Check power factors for each cabinet and for the entire system as explained
in
Chapter 1 - Configuration.
If needed, run Program 91 - 9 twice to initialize program data. Do this if you have just
completed Step 1above. Run Program
03 andturn system power OFF (five seconds) and
then
ON to activate and identifyto Program 03 any subassemblyPCBs installed.
Perform memorytest as in Program00, Part 2.

This chapter explains how to configure a Strata DK280
system. It also provides space to recordthe hardware
and station devicesthat make upthe system.
The focus of this chapter is a series of worksheets,
providing a systematic procedure for determining the
system's size. Tables and example worksheets are
also includedto assist in filling out the worksheets.
System Capacityand Hardware
Description
1.2 System Configuration
The number of CO lines and stations needed
determine the size of the system. The exact hardware
requirements depend on the features required. The
Strata DK280 can support
a maximum of 240 stations,
and 40 CO lines, or, in a squared system, 144stations
and 136 lines. Figure
1 - 1 shows the station and line
capacities for the case of eight
- port RCOU/RCOS CO
line PCBs. There is a trade
- off between stations and
lines. Everygroup of eight stations installeddecreases
the CO line capacity of the system by eight, and vice
versa.
Each system contains a base cabinet (DKSUB280).
The base cabinet has two slots dedicated for the
common control unit and six universal slots, each of
which can support any station or line printed circuit
board (PCB) compatible with the Strata DK280
'system. The base cabinet holds a power supply which
powersall of the devicesconnected to the PCBs in the
base cabinet. The base cabinet can support as many
as 32 stations and 16 trunks with any RCTUA
common control unit; with an RCTUC/D, RCTUB, or
RCTUBNBB common control unit, the base cabinet
can support as many as
40 stations and eight lines.
RCTU processors and the RSlU option PCBs must be
installedin dedicated slots of the base cabinet.
As many as five expansion cabinets (DKSUE280 or
DKSUE424) can be added to the base cabinet to add
more lines and stations to the system. With
DK280
software, DKSUE280 and DKSUE424 are
interchangeable and can be mixed in any order. The
expansion cabinet looks almost identical to the base
cabinet. The DKSUE424 contains two universalslots
reserved for future upgrades and six universal slots
that can be used with all DK280 hardwarehoftware
releases. DKSUE280 provides six universal slots that
can be used with DK280 hardwarehoftware releases;
it also has two additional slots but they cannot be used
with future upgrades.
Like the base cabinet, the expansion cabinet has a
power supply. Each expansion cabinet adds up
to 40
DKT or EKT stations and eight lines. All slots may be
usedfor station or non
- station PCBs.
1.3 Common Control Unit
The system operates with one of three common
control units: the RCTUA (1 or
3), the
RCTUB
(1 or 2), RCTUBA/BB, and the RCTUC/D.
These units consist of a single printed circuit board,
except for the RCTUC (1 or 3)/D
(I, 2, or 3), and
RCTUBAIBB, which consist of two PCBs. All are
installed in dedicated slots in the base cabinet which
are notthe six universal slots.
The common control unit selected for the system
depends on the size of the system and the features
required. The RCTUA
(1 or 3) unit can only support
one cabinet system. The feature capacities are listed
in Table 1
- 1.
January 1996 1 - 1

The RCTUB (1 or 2) or RCTUBNBB units can support
one or two cabinets; its feature capacities are listed in
Table 1-1,The RCTUC
(1 or 3)/D (1, 2, or 3) unit can
support one to six cabinets; its feature capacities are
also listed in Table 1
- 1.
1.4 Printed Circuit Boards
The system interfaces with CO lines, stations, and
peripheral devices via printed circuit boards (PCBs),
which plug into the base and expansioncabinet Slots,
and subassembly PCBs, which mount onto the plug
- in
type PCBs. The Strata DK280 can support the
following PCBs:

1.5 Telephones
The Strata DK280 system supports Toshiba
Proprietary Digital (DKT) and older series Electronic
Telephones (EKTs). Standard telephones
(500 or
2500 series) and devices that require a standard
telephone line interface (fax, modem, VM, etc.) can
also be connectedto DK280:
January 1996
1 - 2

Toshiba provides the following 2000 - series digital
telephones for Strata DK280systems.
DKT-2020SD-20-button speakerphonewith LCD.
H DKT - 201OSD - I 0 - buttonspeakerphonewith LCD.
H DKT-2020S-20-button speakerphone.
H DKT - 201OH - I 0 - button handsfree answerback
telephone.
Toshiba telephones may be equipped with optional
subassemblies; the function of each subassembly is
given inTable 1
- 5.

1.6 Attendant Position Options
The DK280 provides three options for attendant
positions which answer system incomingcalls.
PC Attendant Console - For medium - to - heavy
traffic systems where an attendant must answer
and transfer incoming calls. The PC attendant
console requires a customer
- provided personal
computer plusthe RATU PCB (see Table 1
- 2).
With DK280 Release 2 and
3, up to two consoles
can be connected on systems with RCTUB or
RCTUBA/BB or four with RCTUC/D (2 or 3)
common control PCBs (RCTUA (1 or
3) does not
support attendant consoles).The RATU PCB uses
four station ports in systemsoftware.
Direct Station Select (DSS) Console
- For medium
traffic systems where an attendant must answer
and transfer incoming calls. See Table 1
- 1 for
capacities. The DSS console must connect
to
circuit 8 on a PDKU PCB (see Table 1 - 6 for
configurationconsiderations).
Add
- On - Module (ADM)-For medium traffic,
smaller systems, where an attendant must answer
and transfer incomingcalls. The ADM connectsto
any 2000
- series digital telephone. The ADM
sharesthe associatedtelephonescircuit
so it does
not require a designated PCBor circuit port (see
Table 1
- 5).
1.7 Door Phones (MDFBs)
Up to 12 door phones can be installed in a system
with DK280 Release 1, 2, or
3 RCTUB and C/D, nine
with RCTUA. Each is connected
to a DDCB or HDCB
door phone control box. See Table 1
- 6 for door phone
configurationconsiderations.

Detailedinformationfor AC and reserve battery power
installation is described in Chapter 3
- Cabinet
Installation. These optional assemblies may be
required.
H RBTC - 2M and PBTC - 3M - Battery connecting
cables (seeTable 1
- 7).
H RBDB - Battery power distribution box (see Table
1
- 7).
H RPSBl and RPSB2 - three - outlet AC power strips
(seeTable 1-7).
1.9 Floor Mount Installation
Floor mounting DK280 requires RFlF and RCCB
hardware assemblies; wall mounting DK280 does not
require special hardware but may require
a plywood
backboard(see Chapter %Cabinet Installation).

Notes:
1. All CO Line capacities assume a PIOU, PIOUS, PEPU, RSSU, or RSlU is installed for RCTUBNBB or RCTUC/D, but
not Caller ID RCIU/RCIS PCBs.
2. Limits apply to analog DID and tie lines, not T1 DID/tie lines.
3. T1 lines can be loop start, ground start, tie, or DID (maximum 24 linesper unit, any typeor combination).
4. Maximumcapacity of DKT/EKT 6500 stations per cabinet is 48, less for EKT 2000, 3000.
