Limited Warranty

Toshiba America Information Systems, Inc., (“TAIS”) warrants that this telephone equipment (except for fuses, lamps, batteries, and other consumables) will, upon delivery by TAIS or an authorized TAIS dealer to a retail customer in new condition, be free from defects in material and workmanship for twelve (12) months after delivery. This warranty is void (a) if the equipment is used under other than normal use and maintenance conditions, (b) if the equipment is modified or altered, unless the modification or alteration is expressly authorized by TAIS, (c) if the equipment is subject to abuse, neglect, lightning, electrical fault, or accident, (d) if the equipment is repaired by someone other than TAIS or an authorized TAIS dealer, (e) if the equipment’s serial number is defaced or missing, or (f) if the equipment is installed or used in combination or in assembly with products not supplied by TAIS and which are not compatible or are of inferior quality, design, or performance.

The sole obligation of TAIS or Toshiba Corporation under this warranty, or under any other legal obligation with respect to the equipment, is the repair or replacement by TAIS or its authorized dealer of such defective or missing parts as are causing the malfunction with new or refurbished parts (at their option). If TAIS or one of its authorized dealers does not replace or repair such parts, the retail customer’s sole remedy will be a refund of the price charged by TAIS to its dealers for such parts as are proven to be defective, and which are returned to TAIS through one of its authorized dealers within the warranty period and no later than thirty (30) days after such malfunction, whichever first occurs.

Under no circumstances will the retail customer or any user or dealer or other person be entitled to any direct, special, indirect, consequential, or exemplary damages, for breach of contract, tort, or otherwise. Under no circumstances will any such person be entitled to any sum greater than the purchase price paid for the item of equipment that is malfunctioning.

To obtain service under this warranty, the retail customer must bring the malfunction of the machine to the attention of one of TAIS’ authorized dealers within the twelve (12) month period and no later than thirty (30) days after such malfunction, whichever first occurs. Failure to bring the malfunction to the attention of an authorized TAIS dealer within the prescribed time results in the customer being not entitled to warranty service.

THERE ARE NO OTHER WARRANTIES FROM EITHER TOSHIBA AMERICA INFORMATION SYSTEMS, INC., OR TOSHIBA CORPORATION WHICH EXTEND BEYOND THE FACE OF THIS WARRANTY. ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND FITNESS FOR USE, ARE EXCLUDED.

No TAIS dealer and no person other than an officer of TAIS may extend or modify this warranty. No such modification or extension is effective unless it is in writing and signed by the vice president and general manager, Telecommunication Systems Division.

Strata DK

General End User Information

The Strata DK Digital Business Telephone System is registered in accordance with the provisions of Part 68 of the Federal Communications Commission’s Rules and Regulations.

FCC Requirements

Means of Connection: The Federal Communications Commission (FCC) has established rules which permit the Strata DK system to be connected directly to the telephone network. Connection points are provided by the telephone company— connections for this type of customer-provided equipment will not be provided on coin lines. Connections to party lines are subject to state tariffs.

Incidence of Harm: If the system is malfunctioning, it may also be disrupting the telephone network. The system should be disconnected until the problem can be determined and repaired. If this is not done, the telephone company may temporarily disconnect service. If possible, they will notify you in advance, but, if advance notice is not practical, you will be notified as soon as possible. You will be informed of your right to file a complaint with the FCC.

Service or Repair: For service or repair, contact your local Toshiba telecommunications distributor. To obtain the nearest Toshiba telecommunications distributor in your area, call Toshiba America Information Systems, Inc., Telecommunication Systems Division in Irvine, CA (949) 583-3700.

Telephone Network Compatibility: The telephone company may make changes in its facilities, equipment, operations, and procedures. If such changes affect the compatibility or use of the Strata DK system, the telephone company will notify you in advance to give you an opportunity to maintain uninterrupted service.

Notification of Telephone Company: Before connecting a Strata DK system to the telephone network, the telephone company may request the following:

1.Your telephone number.

2.FCC registration number:

♦Strata DK may be configured as a Key or Hybrid telephone system. The appropriate configuration for your system is dependent upon your operation of the system.

♦If the operation of your system is only manual selection of outgoing lines, it may be registered as a Key telephone system.

♦If your operation requires automatic selection of outgoing lines, such as dial access, Least Cost Routing, Pooled Line Buttons, etc., the system must be registered as a Hybrid telephone system. In addition to the above, certain features (tie Lines, Off-premises Stations, etc.) may also require Hybrid telephone system registration in some areas.

♦If you are unsure of your type of operation and/or the appropriate FCC registration number, contact your local Toshiba telecommunications distributor for assistance.

3.Ringer equivalence number: 0.3B. The ringer equivalence number (REN) is useful to determine the quantity of devices which you may connect to your telephone line and still have all of those devices ring when your number is called. In most areas, but not all, the sum of the RENs of all devices connected to one line should not exceed five (5.0B). To be certain of the number of devices you may connect to your line, as determined by the REN, you should contact your local telephone company to ascertain the maximum REN for your calling area.

4.Network connection information USOC jack required: RJ1CX, RJ2EX, RJ2GX, RJ48C, RJ48X, RJ11, RJ14C, RJ21X (see Network Requirements in this document). Items 2, 3 and 4 are also indicated on the equipment label.

Radio Frequency Interference

Warning: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the manufacturer’s instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case, the user, at his/her own expense, will be required to take whatever measures may be required to correct the interference.

This system is listed with Underwriters Laboratory.
UL Requirement: If wiring from any telephone exits the building or is	U
subject to lightning or other electrical surges, then secondary protection	U	L
is required. Secondary protection is also required on DID, OPS, and tie	®	L
lines. (Additional information is provided in this manual.)

Important Notice — Music-On-Hold

In accordance with U.S. Copyright Law, a license may be required from

the American Society of Composers, Authors and Publishers, or other similar organization, if radio or TV broadcasts are transmitted through the music-on-hold feature of this telecommunication system. Toshiba America Information Systems, Inc., hereby disclaims any liability arising out of the failure to obtain such a license.

CP01, Issue 8, Part I Section 14.1

Notice: The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the Equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

CAUTION! Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

CP01, Issue 8, Part I Section 14.2

Notice: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The terminal on an interface may consist of any combination of devices subject only to the requirement that the sum of the Ringer Equivalence Numbers of all the Devices does not exceed 5.

Digital Telephone/Central Office (CO) Line Circuits

The main PCB (WMAU) has four integrated circuits that can connect to digital corded and/or cordless telephones, stand-alone data interface units (PDIU-DSs), and digital door phone/lock control units (DDCB). Each of the digital telephones can support a PC Data Interface Unit (RPCIDI) or up to two Add-on Modules (DADMs). It does not support a DDSS console.

Two circuits for loop start CO lines are built into the main PCB. Each line can be programmed for Dual-tone Multi-frequency (DTMF) or dial pulse signaling. It includes a switch to control potential excess volume from a nearby private branch exchange (PBX) or CO. Built-in gas tubes help protect each circuit from lightning. Each line supports Caller ID when optional equipment is added.

DK14 (fully-loaded	Estimated Battery
system)	Time (hours)
One HPFB	0.5~1.0

Two HPFBs	1.0~2.0

Notes

●

Reserve power time varies with system call traffic.

AC power must be available when HPFB is first installed. HPFB recharge time is 48 hours per HPFB.

Power Failure Interface

The Strata DK14 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 will automatically connect to the CO1 line. This feature is independent of the HPFB.

Music-on-Hold (MOH) Interface

Customers can connect their own MOH source to this interface. The source can also feed external page speakers and telephone speakers with Background Music (BGM).

Paging Interface

This 600-ohm interface can support a Toshiba External Speaker (HESB) or a customer-supplied amplifier and speaker for Paging, Night Ringing over Page, and BGM applications.

Flexible Relay Contacts

A relay contact can be programmed to either mute BGM during a page announcement over external speakers, to operate a device—such as an answering machine or ringing bell—during the Night Mode, or to provide on-off control for a MOH source.

Strata DK14

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 makes the Strata DK14 circuit designs 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 minimizes system power requirements.

Stored Program Control

The system uses a 16-bit microprocessor for stored program control. The Strata DK14 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.

Strata DK General Description 6/00

Strata DK14

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, which can help cut costs and save time, is available through a customer-provided modem connected to the maintenance port.

DKi Admin/DKi Backup

Toshiba DKi Admin Release 4.0 software enables customer data (configuration, station, and system options) to be downloaded to a PC and stored on a computer disk. The customer data can be added to, or changed, using the PC independent of the DK System.

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 program is also available. The program consists of a small subset of DKi Admin functions which can perform backup, restore and upgrade functions, but cannot edit customer databases.

Strata DK40i	2

This chapter provides an overview of the Strata DK40i Release 4.3 system and its capacities. Release 4.3 enables the DK40i to provide Automatic Call Distribution (ACD), E911 CAMA, T1, ISDN PRI and BRI U and S/T interfaces.

The Strata DK40i Base Key Service Unit (KSU) is a compact system that provides many of the features offered by much larger systems. The KSU is designed for convenient wall-mounting and occupies very little space (see Figures 4, 5 and Table 4.)

Digital Telephone Circuits

The main circuit board (TMAU2) in the Strata DK40i Base KSU has eight integrated circuits that can connect to Toshiba-proprietary digital telephones (including the cordless telephone), Standalone Data Interface Units (PDIU-DSs), Digital Door Phone/Lock Control Units (DDCB), and Digital Direct Station Selection Consoles (DDSS).

Furthermore, each of the digital telephones can support a PC Data Interface Unit (RPCI-DI) or up to two Add-on Modules (DADMs).

Central Office (CO) Line Circuits (TCOU/TDDU/TBSU/TBUU)

The following PCBs can be installed in the DK40i Base KSU:

♦TCOU provides four circuits for loop start CO lines.

♦TDDU provides four circuits for Direct Inward Dialing (DID) lines

♦TBSU provides two circuits for BRI lines or stations (see TBSU below)

♦TBUU provides two BRI U interface circuits for lines or stations

10	Strata DK General Description 6/00

Strata DK40i

Base KSU Architecture

The CO line interface and DID interface unit can be programmed for DTMF or dial pulse signaling and each line has a switch to control potential excess volume that could be created by a nearby PBX or CO. Built-in gas tubes help protect each TDDU and TCOU line from lightning. An optional RDDU (for DID lines) installed in the Expansion Unit requires an external secondary protector. DID lines require the optional K5RCU2 tone receiver.

ISDN BRI S/T Circuits (TBSU)

The TBSU PCB provides two Basic Rate Interface (BRI) circuits for DK40i. The TBSU can only be installed in the DK40i Base KSU.

The TBSU circuits are four-wire S/T type circuits and connect to the PSTN BRI lines using a dealer-supplied UL-listed Network Terminator unit (NT1). In Canada, the NT-1 must be CSA certified. On the station side, they can connect to S-type ISDN Terminal Equipment (TE) or Terminal Adapters (TA).

ISDN BRI U Circuits (TBUU)

DK BRI U interface circuits can be configured to connect to an ISDN line circuit (NT mode, lineside) or to ISDN U-type terminal equipment TE1 or terminal adapters TA (LT mode, station side). The TBUU provides two BRI-U circuits that can be configured independently for line or station circuits.

Note The TBSU and TBUU contains two circuits, each of which reduces the system capacity by two station ports or two CO lines. If the BRI circuit is configured as a station circuit, the circuit assumes two station ports. If the BRI circuit is configured as a line circuit, the circuit assumes two CO lines. BRI lines can be used for voice and data calls.

Caller ID (TCIU2)

An optional Caller ID PCB (TCIU2) can be added to the four-circuit loop start CO line PCB (TCOU) to provide four Caller ID circuits. Local telephone companies do not provide Caller ID on DID lines; so the TCIU2 PCB cannot be added to the four-circuit DID PCB (TDDU). Caller ID can also be added with the RCIU2 and KCDU2. See “Caller ID Interface Unit (RCIU2)” on Page 41 and “Caller ID” on Page 69 for more information.

Standard Telephone Interface Unit (KSTU2)

The optional KSTU2 provides four circuits that can interface with DTMF for rotary dial standard telephones and other single-line devices, including: Strata AirLink Wireless Base Station Interface Adapters (BSIAs) and handsets, fax/modems (14.4 bps max.), Voice Mail and Auto Attendant devices, off-premises stations, alternate BGM source and dictation equipment. These devices may require that the optional tone receiver (K5RCU or K5RCU2) be installed in the DK40i Base KSU to interpret the DTMF signals the above devices may transmit.

The KSTU2 does not support message waiting lamps on standard telephones. The RSTU2 must be installed in the Expansion Unit to support message waiting lamps.

DTMF/ABR Tone Detection Receiver (K5RCU and K5RCU2)

Station users in systems that have the optional K5RCU or K5RCU2 installed can access Automatic Busy Redial (ABR) and communicate with devices, such as standard telephones or voice mail machines that require DTMF signaling.

This unit is also required for Direct Inward System Access (DISA) and built-in or external Auto Attendant operation, as well as for DID and Tie lines. Each K5RCU or K5RCU2 PCB contains five shared receivers.

Strata DK General Description 6/00

Strata DK40i

Expansion KSU Architecture

Feature Key (KKYS)

The system can be upgraded with an optional feature key, the KKYS, which installs onto the K5RCU PCB in the Base KSU. The KKYS1 provides Automated Attendant (AA); KKYS2 provides AA and ACD; and KKYS3 provides AA and ACD/MIS.

SMDR, SMDI, ACD/MIS and Maintenance DKi Admin/Modem (TTY) Interface (TSIU)

The TSIU PCB provides two RS-232 interface ports (modular jacks) that allow the DK40i system to connect to an SMDR Call Accounting device, a DKi Admin PC or external modem for system maintenance/administration, ACD/MIS reports using Toshiba’s Insight DK software, or an SMDI interface for Voice Mail. It does not have a built-in modem capability.

Only one TSIU can be installed per DK40i system. When the TSIU PCB is installed, the PIOU can still be installed for zone paging, control relays, and an SMDR RS-232 interface, built-in (IMDU) maintenance modem, ACD/MIS processor or VM SMDI or maintenance interface.

Expansion KSU Architecture

The optional Expansion KSU, which attaches easily to the side of the Base KSU, offers four universal slots that can host a variety of line and telephone PCBs (see Figure 7). See Chapter 4 – Universal Slot PCBs for descriptions of PCBs.

This section shows the maximum basic and CO configurations that are possible with the DK40i. There is a variety of configuration combinations of digital and standard telephones with CO lines, including loop start, ground start, Tie, and DID lines. Any loop or ground start CO line can be equipped with Caller ID.

The DK40i Base KSU comes equipped with eight digital telephone station circuits. One of four optional PCBs can be added to provide either four loop start or DID lines, or two ISDN BRI S/T or U circuits. Another optional TCIU2 PCB can be added to the Base KSU loop start line PCB to provide Caller ID interface. An optional KSTU2 PCB can be added to provide four standard telephone circuits (ports).

An optional Expansion KSU can be added to the DK40i to increase the system capacity to 28 station ports and 12 CO lines (see Figure 5). A maximum of 28 station ports and 12 CO line interfaces are allowed in the system (Base KSU plus Expansion KSU). Base capacity is 12 station ports and 4 CO line or 2 BRI circuit interfaces.

	CO Lines	12

	Station Ports	28

	BRI Line Circuits	6

	BRI Station Circuits	10

Attaining maximum system capacities depends on power consumption of a particular configuration (see Table 6). Power factor calculations in accordance with the Strata DK I&M Manual will determine if the maximum capacities in these tables can be reached.

1.There are four universal slots in the DK40i expansion unit.

2.Line and station capacities cannot exceed 28 stations and/or 12 CO lines. Incremental capacities depend on the type of station/line PCBs installed. All increments are not available with all PCB types.

3.Increments vary and depend on the type of line PCBs installed.

4.In the D40i, DID and Tie, lines do not use up station ports as in DK40, R3.1 and the DK424 R3.2. Each BRI line circuit uses up to two CO lines of system capacity and no station ports.

5.Each S/T type circuit requires an NT-1 device when connected to a Central Office BRI line circuit.

The DK40i Base and Expansion cabinets provide an extensive number of features for a telephone system of its size. See Table 40 on Page 109 for a list of DK40i, Release 4.3 features and capacities.

ISDN BRI Lines

Stations can be a combination of ISDN TE-1 and TA S-type devices and digital, electronic or standard telephones. CO line combinations include ground or loop start, DID, Tie or ISDN BRI. Each BRI line circuit uses up two CO lines at system capacity. All other line circuits use up one CO line of system capacity.

Each BRI station circuit uses up to two station ports of system capacity. All other station circuits use up one station port of system capacity.

1.Each BRI circuit (S/T and/or U-type) provides two B channels plus one D channel. Each (S/T) BRI station circuit allows up to two TE-1 and TA devices to share the BRI B channels (two simultaneous calls maximum per BRI circuit.). Each BRI-U circuit supports one TE-1 or TA device.

2.Maximum BRI line capacity. BRI station circuits do not use up CO line channels and vice versa. Also, station circuits use 2B + 1D channel; lines use one B channel which enables one BRI circuit to provide two lines.

3.Other stations include Toshiba digital and electronic telephones, or attendant consoles, standard telephones and devices.

4.BRI S/T circuits are available with TBSU and RBSU/RBSS PCBs and BRI-U circuits are available with TBUU and RBUU/RBUS PCBs. Each BRI line circuit (S/T or U) provides two BRI CO lines (B channels) for incoming/outgoing calls.

5.Other lines include analog and digital (T1 or PRI) loop start, ground start, DID, and Tie lines.

Peripherals

The DK40i Base KSU can support a number of peripherals, which are not considered as stations or lines and do not affect the maximum station and line capacities. The DK40i Base KSU comes standard with built-in interfaces for connecting the following dealer-supplied equipment: an amplifier and speaker for paging and night ringing, Music-on-Hold (MOH) source, reserve power batteries, and emergency standard telephone for system power failure occurrences when using loop start lines in the base cabinet.

A relay contact is also provided to control one of the following peripherals: MOH source, night bell, or page amplifier mute control.

An optional KSTU2 PCB provides an alternate background music source interface. The music plays through Toshiba telephone speakers, as opposed to the external page speakers.

The optional TSIU PCB provides two RS-232 interface ports to connect two of four options: a DKi Admin PC (or external modem for remote maintenance); or VM SMDI, ACD/MIS or an SMDR port to connect a call accounting device or printer. An Expansion Unit RS-232 interface PCB is required if all four features are needed.
