AC power must be available when first installing reserve power batteries.
Strata DK40i Functional Block Diagram 16Strata DK General Description 6/00 Power Failure Interface The Base KSU provides an interface for a dedicated backup standard telephone during an AC input power failure. If the system AC input power fails, the backup telephone automatically connects to the CO1 line. The backup telephone is disabled when the system operates during normal power conditions. This feature is independent of Battery Backup and is available when loop start lines are installed in the Base KSU. A power failure telephone cannot be installed for DID lines. Music-on-Hold Interface Customers can connect their own MOH source to this interface. The source can also feed external page speakers and telephone speakers with BGM. Paging Interface – This 600-ohm interface supports a Toshiba External Speaker (HESB) or a customer-supplied amplifier and speaker for Paging, Night Ringing over Page, and BGM. Flexible Relay Contacts – A relay contact can be programmed to either mute BGM during a page announcement over external speakers, to operate a device: i.e., an answering machine or ringing bell during the Night Mode, or to provide on-off control for a MOH source. Functional Block Diagram Figure 8 shows the Strata DK40i Base and Expansion KSU PCBs and the available lines, stations and peripherals. Basic voltage and cabling information is also included.

Strata DK40i Network Requirements 18Strata DK General Description 6/00 Network Requirements See Table 43 on Page 122 for network requirements of station and line PCBs and interface cards. System Technology Pulse Code Modulation Digital switching talkpaths enable all CO and intercom lines to be accessed simultaneously. Analog-to-digital and digital-to-analog conversion is done by CODECs (coder plus decoder) on station and CO line PCBs. Custom Electronic Circuitry Large Scale Integration (LSI) technology enables the Strata DK40i circuit designs to be simple and efficient. Gate arrays using very large scale integration save vast amounts of space by using the latest technology. More circuitry fits onto smaller PCBs for a more compact system. Widespread use of CMOS circuits minimize system power requirements. Stored Program Control The system uses a 16-bit microprocessor for stored program control. Strata DK40i system operating software is stored on Read Only Memory (ROM), and individual configuration and custom programming is stored on Random Access Memory (RAM). A lithium battery with a life span of at least six years preserves RAM in the case of a power failure. Microprocessors The system’s main microprocessor is a 16-bit 68000-type that operates at a clock speed of 8 MHz. In addition, some PCBs use 8-bit, TMP90C840-type local microprocessors that run at 10 MHz. This distributed microprocessing architecture is used system-wide. Maintenance and Programming Hardware maintenance and repair procedures describe how to quickly locate, remove, and replace defective parts and PCBs. System programming can be performed without taking the system out- of-service. On-site programming can be executed with any 20-button proprietary LCD telephone or with a DKi Admin PC connected to an optional maintenance port. Off-site programming with DKi Admin is available through a customer-provided modem connected to the maintenance port. DKi Admin/DKi Backup Toshiba DKi Admin software Release 4.3.1 and higher, enables customer data (configuration, station, and system options) to be downloaded to a PC and stored on a computer disk. The new customer data can then be uploaded to the DK System from the PC, changing customer program options on-site or remotely over telephone lines and/or modems. The DKi Backup software is also available. DKi Backup consists of a subset of DKi Admin functions such as backup, restore and upgrade functions, but it cannot edit customer databases. StrataControl StrataControl™ is a Windows-based PC application enabling limited access to Strata DK40i and DK424i system programming functions. See “StrataControl” on Page 89 for more information.
Strata DK General Description 6/0019 Strata DK424i3 This chapter covers the new Strata DK424i digital business telephone system. Strata DK424i easily connects to outside public telephone lines (CO lines). All of the telephones (stations) tied to the system can have direct access to each other as well as to the public network. A modular design and a choice of four processors, also called common control units, enables the system to fit a variety of customer needs and capacities. The DK424i can be configured as a single cabinet system that provides capacity of up to 64 CO lines and stations combined, and can grow to a five cabinet system that provides capacity for up to 432 CO lines and stations combined. These capacities assume that one slot is reserved for an optional External Page/Maintenance interface PCB. (See Ta b l e s 1 3~15 for details.) The system line and station capacity can be increased by adding additional cabinets (see Figure 9 and Table 10) which have universal slots capable of interfacing with most line, station, and option interface PCBs available with the system. Architecture The Base Cabinet and optional Expansion Cabinets are the building blocks of the system. Each system has a Base Cabinet, and can have from one to four Expansion Cabinets. All lines, stations, and options are tied together through the cabinets. Table 10 Cabinet Specifications CabinetWeightHeightWidthDepth Base Cabinet (CHSUB672) 31 lbs. 11.625 in. 26.5 in. 10.3 in.

Strata DK424i Processor PCBs 20Strata DK General Description 6/00 Processor PCBs The system operates with one of four processors (B1CU, B2CAU/B2CBU, B3CAU/B3CBU, or B5CAU/B5CBU). These processors can only be installed in dedicated slots in the Base Cabinet (slots B101 and B102). The B1CU unit consists of a single PCB. The B1CU processor supports only the DK424i Base Cabinet with up to eight universal slots. B2CAU/B2CBU consists of two PCBs that support up to two cabinets, with up to 14 universal slots. Expansion Cabinet slots S207~S210 are not available with the B2CAU/B2CBU processors. B3CAU/B3CBU consists of two PCBs that support up to three cabinets, with up to 28 universal slots. B5CAU/B5CBU consists of two PCBs that supports up to five cabinets, with up to 48 universal slots. Each processor provides a MOH/BGM source interface, and connectors to mount optional DTMF receiver PCBs required for some CO line types and peripherals, as described below. Each processor provides an interface for connecting an optional feature key (RKYS) as described below. B3CAU/B3CBU and B5CAU/B5CBU require a remote maintenance PCB, usually installed in slot S101; the remote maintenance PCB is optional for the B1CU and B2CAU/B2CBU. All configurations shown in this document assume this PCB is installed. Ta b l e 11 lists the clock speed and available chips and memory for each processor. Processor PCB Subassemblies Subassemblies required for some features can be added to the processor PCBs. Also see “Summary of PCBs and Subassemblies” on Page 45. DTMF Receiver Subassembly (BRCS) The BRCS is required to translate DTMF tones needed for DISA, Tie/DID/Dialed Number Identification Service (DNIS)/Automatic Number Identification (ANI) lines, voice mail, AA announcement devices, DTMF standard telephones, and other devices to data signals for the system. The BRCS can be attached to the processor and is available with either 4, 8, or 12 (BRCS-4, -8 or -12) shared receiver circuits. See Table 38 on Page 95 for more information.

Strata DK424i Maximum Station/Line Capacities 22Strata DK General Description 6/00 Expansion Cabinets Expansion cabinets can be added to increase station and CO line capacity of systems that allow multiple cabinets. Figure 11 shows an example of the interior of an expansion cabinet. Refer to the following section for station/line capacities. Ta b l e 1 3 shows the number of stations and lines allowed when additional cabinets and PCBs are used. Printed Circuit Boards (PCBs) PCBs are installed in the cabinets to provide interface for stations, lines, and peripherals. Each PCB measures 7.5 x 5.5 inches (190 x 140 mm) and mounts in the slot with a 44-pin backplane connector. PCB external connections to station equipment are made to the Main Distribution Frame (MDF) using industry-standard connectors. Also see Chapter 4 – Universal Slot PCBs. Maximum Station/Line Capacities Attaining maximum system capacities depends on power consumption of a particular configuration. Configurations for a fully expanded system can range from 200 lines or 336 stations. All capacity configurations shown below assume one slot contains an eight circuit station PCB and one universal slot is reserved for an optional External Page/Maintenance PCB. A summary of the maximum number of lines and stations by processor is shown in Table 13.
