DK424 Configuration
DK424 Configuration4
This chapter explains how to configure the Strata DK424 system. The system has a modular 
design which enables it to support a number of station and CO line configurations. The main 
component of the system is the common control unit (RCTU) Printed Circuit Board (PCB).
The focus of this chapter is a series of worksheets, providing a systematic procedure for 
determining the system’s size. The worksheets also provide space to record the hardware and 
station devices that make up the system. Tables and example worksheets are included to assist you 
in filling out the worksheets.
Important!Prior to Release 4, Tie and DID lines used station ports. With Release 4.0 and 
higher processors, these lines do not use station ports, allowing larger capacity 
systems when Tie and DID lines are required.
System Configuration
Important!
System Configuration can be complex and time consuming. For best results:
©Use DKQuote to provide easy, fast, automated configuration. It runs on an IBM-compatible 
Pentium® PC or higher, equipped with a 110MB or larger hard drive, a 3.5” 1.44 MB high 
density floppy disk drive, 16MB RAM, and Windows® 98/95 or Windows NT®. See the 
DKQuote User Guide for more information.
©If the above software is not available, use the Worksheets in this chapter.
The DK424’s main components are: the DK424 Base Cabinet (DKSUB424), DK424 Expansion 
Cabinets (DKSUE424), and four system processors (RCTUA4, RCTUBA3/BB4, RCTUC3/D4, 
and RCTUE3/F4). The processor used in the system depends on the features and number of 
telephones and CO lines required.  Each cabinet is shipped with its required Power Supply 
(RPSU280); the same power supply used in DK280 cabinets.
See Chapter 5 – DK424 Installation for detailed information on installing RCTU PCBs.

Base Cabinet
The DK424 Base Cabinet provides two designated slots for the RCTU processor and six universal 
slots for station, line, and feature PCBs. It provides six connectors for expanding the system to a 
maximum of six Expansion Cabinets. It comes with a Motherboard Jumper Unit (MBJU) installed 
between the R11 and RCTU slot on the front side of the backplane motherboard. The MBJU is 
removed only when RCTUE/F is installed. MBJU is installed for all other DK Release 1~4 RCTU 
processor PCBs.
Expansion Cabinets
Cabinet and Universal Slot Capacity: Up to six DK424 Expansion Cabinets can be connected to a 
DK424 Base Cabinet. The number of DK424 Expansion Cabinets allowed depends on which 
processor is installed in the DK424 Base Cabinet. 
The DK424 Expansion Cabinets support either six or eight universal slots, depending on which 
processor is installed in the DK424 Base Cabinet. 
©All Expansion Cabinets are six slot cabinets except DK424 Expansion Cabinets. DK424 
Expansion Cabinets provide eight slots, but only when connected to a DK424 Base Cabinet 
controlled by an RCTUE3/F3 processor with the MBJU removed.
©No DK424 Expansion Cabinets are allowed when connected to the DK424 Base Cabinet with 
an RCTUA processor installed.
©One DK424 Expansion Cabinet provides six universal slots when connected to the DK424 
Base Cabinet with an RCTUBA/BB processor installed.
©Up to five DK424 Expansion Cabinets provide six universal slots each, when connected to the 
DK424 Base Cabinet with an RCTUC/D processor installed.
©Up to six DK424 Expansion Cabinets provide eight universal slots each, when connected to a 
DK424 Base Cabinet with an RCTUE/F processor installed.

DK424 and DK280 Compatibility
DK424 cabinets replace DK280 cabinets in the DK product line structure. DK424 Expansion 
Cabinets began shipping in June 1995 and DK424 Base Cabinets in February 1997. All old DK280 
Release 1~3 processors and DK280 Base/Expansion Cabinets can be mixed with new DK424 Base 
and Expansion Cabinets with the following criteria (see Ta b l e s  4 - 2 and 4-3):
 
 
©DK424 and DK280 Cabinets can be mixed in any combination, with one exception. If seven 
cabinets are required, an RCTUE/F processor must be installed in a DK424 Base Cabinet and 
the sixth Expansion Cabinet must be a DK424. In this case DK280 Expansion Cabinets provide 
six universal slots and DK424 Expansion Cabinets provide eight universal slots.
©DK280 and DK424 Base Cabinets provide six universal slots maximum in any configuration 
and any RCTU processor can be installed.
©DK280 Expansion Cabinets provide six universal slots maximum in any configuration.

©DK424 Expansion Cabinets provide six universal slots maximum in any configuration with a 
DK280 Base Cabinet, including a DK280 Base Cabinet with an RCTUE/F processor.
©DK424 Expansion Cabinets provide eight universal slots in one configuration only: when 
connected to a DK424 Base Cabinet controlled by an RCTUE/F processor (MBJU jumper 
must be removed - see installation for details). DK424 cabinets provide six universal slots in 
all other configurations.
©An RCTUE/F processor can be installed in a DK280 Base Cabinet. When an RCTUE/F 
processor is installed in a DK280 Base, only five Expansion Cabinets (DK424 and/or DK280) 
can be installed. These Expansion Cabinets provide only six universal slots.
©All older DK280 Release 1~3 processors will function in the DK424 Base Cabinet. The 
features available depend on the respective release and type of the RCTU. These processors 
include RCTUA1, RCTUA3, RCTUB1, RCTUB2, RCTUBA3/BB3, RCTUC1/D2 and 
RCTUC3/D3.
©When an older processor is installed in the DK424 Base Cabinet, the DK424 and DK280 
Expansion Cabinets provide six universal slots and the MBJU jumper must be installed - 
see RCTU installation for details.
©RCTUA in a DK424 Base allows no Expansion Cabinets.
©RCTUB or RCTUBA/BB in a DK424 Base allows one DK424 or DK280 Expansion 
Cabinet with six universal slots.
©RCTUC/D in a DK424 Base allows up to five DK424 and DK280 Expansion Cabinets in 
any combination. These Expansion Cabinets provide six universal slots.
Designated Speaker OCA, DIU Data, and T1 slots
DK424 systems require that PDKU2 PCBs that support Speaker Off-Hook-Call-Announce (OCA) 
and PDIU-DS and RPCI-DI PCBs for data applications must be placed in the slots designated in 
Tables 4-4 and 4-5.
NotePDKU2s that support Handset OCA and RPCI TAPI-only can operate in any slot.
Additionally, to enable T1/DS-1 interface, the RDTU PCB(s) must be placed in certain slots, with 
corresponding slots left vacant. (The operation of certain channels necessitates vacant slots.) 
RDTU PCBs can be placed in the slots in bold type; the vacant slots are not in bold in the 
following tables.
Example: for cabinet 1, if an RDTU is placed in slot 13 and you want to use RDTU channels 
17~24, then slot 14 must be left vacant. If you installed a second RDTU, it would go into slot 15; 
slot 16 must also be vacant if you want to use RDTU channels 17~24.

System Capacity
The number of CO lines and stations needed determine the size of the system. Ta b l e s  4 - 9 and 4-12 
show the station and line capacities for eight-port RCOU/RCOS CO line PCBs.
There is a trade-off between stations and lines. Every group of eight stations installed decreases the 
CO line capacity of the system by eight, and vice versa. The exact hardware requirements depend 
on the features required.
 Tables 4-9~4-12 assume one cabinet slot is used for an Optional Interface PCB.
