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. Y our 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.

DK14 and DK40i

Key system: Hybrid: CJ6MLA-74478-MF-E

DK424

Hybrid: Key system: CJ69XA-10242-KF-E PBX: CJCHN-22757-PF-E

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.

CJ6MLA-74479-KF-E

CJ69XA-10243-MF-E

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

subject to lightning or other electrical surges, then secondary protection is required. Secondary protection is also required on DID, OPS, and tie 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. Toshib a 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 suc h connections th e mselves, but

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.

should contact the appropriate electric inspection authority, or electrician, as appropriate.

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 St rata 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 co mpact 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 le ast six years p reserves RAM in the case of a power fai lure.

Strata DK14

System Technology

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 5/99 7

Strata DK14

Maintenance and Programming

Hardware maintenance and repair procedures describe how to quickly loca te , re mo ve, a nd r epl ac e defective parts and PCBs. System programming can be performed without taking the system outof-service.

On-site programming can be executed with any 20-button proprietary LCD telephone or with a DKAdmin PC connected to an optional maintenance port.

Off-site programming with DKAdmin, which can help cut costs and save time, is avai lable through a customer-provided modem connected to the maintenance port.

DKAdmin/DKBackup

T osh iba DKAdmin Rel ease 4 .0 soft ware enab les c ustomer data (conf igura tion, stati on, and syst em options) to be downlo aded to a PC and st ored on a comp uter disk . The c ustomer data c an be adde d 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 DKBackup software program is also available. The program consists of a small subset of DKAdmin 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 System and its capacities. 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 Figure 4 and Table 4.)

Station and CO Lines

The DK40i Base KSU comes equipped with eight digital telephone station circuits. One of three optional PCBs can be added to provide either four loop start or DID lines, or two ISDN BRI S/T circuits. An optional TCIU2 Pr inted Circuit Board (PCB) can be add ed to the Bas e KSU loop star t line PCB to provide Caller ID interface. An optional KSTU2 PCB can be added to provide four standard telephone circuits (ports).

Note An optional Expansion KSU can be added to the DK40i to increas e the sys tem capac ity to

28 station ports and 1 2 CO lines (se e Figu re 5 ). A maximum of 28 s tation por ts a nd 12 CO line interfaces are allowed in the system (Base KSU plus Expansion KSU). Base capacity is 12 station ports and 4 CO line interfaces.

DID lines require the optional K5RCU2 tone receiver.

Strata DK General Description 5/99 11

Strata DK40i

Base KSU Architecture

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 contains two circuits, each of which reduces the system capacity by t wo stati on ports or two CO lines. If the BRI circuit is configured 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.

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).

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 Ca ller 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 65 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 devic es, includi ng: Strat a AirLi nk Wirel ess Bas e Stat ion Inte rface Adapters (BSIAs) and handsets, fax/modems (14.4 bps max.), Voice Mail and Auto Attendant devices, off-premises st at ions, a lt ernat e BGM source and dictation equipment. These de vices may require that the optional tone receiver (K5RCU or K5RCU2) be installed in the DK40i Base KSU to interpret the DTMF signals the a bo ve devices may tra nsmit.

The KSTU2 does not support message wait ing lamps on standar d telephone s. 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 syste ms that have the optiona l K5RCU or K5RCU2 installed can acce ss 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.

Auto Attendant Feature Key (KKYS)

The system can be upgraded with an optional built-in Auto Attendant (AA). The KKYS installs onto the K5RCU PCB in the Base KSU.

SMDR, SMDI, and Maintenance DKAdmin/Modem (TTY) Interface (TSIU)

The TSIU PCB provides two RS-232 interface ports (modular jacks) that allow the DK40i sys te m to connect to an SMDR Call Accounting device, a DKAdmin PC or external modem for system maintenance/administration, or an SMDI interface for Voice Mail. It does not have a built-in modem capability.
