SECTION 100-816-202

MARCH 1993

1 GENERAL

1.00 This chapter defines the installation site re-

quirements necessary to ensure a proper operating environment for the STRATA DK8 and DK16. Also included are grounding requirements.

2 INPUT POWER REQUIREMENTS

2.00 The system requires an input power source

of 117VAC nominal (85VAC ~ 135VAC), 50/60 Hz, 15 amps. The AC outlet is recommended to be

dedicated

ground (refer to Paragraph 4). This is to eliminate interference from branch circuit motor noise or the like, and to prevent accidental power-off.

2.01 To avoid accidental power turn-off, it is recommended that an ON/OFF wall switch used on this dedicated AC circuit.

3.03 If reserve power is to be installed for the STRATA DK16, the batteries will require a wellventilated location close (within nine feet) to the DKSUB16 (the optional Toshiba-supplied battery cable is 9 feet in length). The STRATA DK8 reserve battery (HPFB) should be mounted directly above the DKSU8 as shown in Figure 2-1.

3.10 Electrical/Environmental Requirements and Characteristics

3.11 The electrical/environmental requirements

and characteristics for each system are provided in Table 2-A.

4 GROUNDING REQUIREMENTS

4.00 The systems require a solid earth ground for

proper operation. Failure to provide ground may lead to confusing trouble symptoms and, in extreme cases, system failure. The AC power cord contains a conductor for the "third wire ground" provided by the commercial power outlet. The third-wire ground should be the only ground necessary for the DK8/DK16; this ground must originate at the buildings main power distribution panel and have a solid connection to earth ground. (Figure 2-4)

4.10 Third Wire Ground Test

3.02 The following conditions must be considered

when selecting a location for the key service unit(s): The location MUST BE:

•

Dry and clean

•

Well ventilated

•

Well illuminated

•

Easily accessible

The location MUST NOT BE:

•

Subject to extreme heat or cold

•

Subject to corrosive fumes, dust, or other air-

borne contaminants

•

Subject to excessive vibration

•

Next to television, radio, office automation, or

high frequency equipment

4.11 Test the "third wire ground" for continuity by either measuring the resistance between the third prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm), or by using a commercially available earth ground indicator. If neither procedure is possible, perform the following earth ground test procedure:

WARNING! Hazardous voltages that may cause death or injury are exposed during the following test. Use great care when working with AC power line voltage.

1) Obtain a suitable voltmeter, and set it for a possible reading of up to 250 VAC.

2) Connect the meter probes between the two main AC voltage terminals (white and black wires) on the wall outlet. The reading obtained should be between 100 ~ 120 VAC.

3) Move one of the meter probes to the third terminal (green wire ground). Either the same reading or a reading of zero volts should be obtained.

4) If the reading is zero volts, leave one probe on the ground terminal and move the other probe to the second voltage terminal.

CAUTION! If a reading of zero volts is obtained on both voltage terminals (white wire to green wire, black wire to green wire), the outlet is not properly grounded. Omit steps 5 and 6, and proceed directly to step 7.

2-3

INSTALLATION-SITE REQUIREMENTS SECTION 100-816-202 MARCH 1993

5) If a reading of zero volts on one terminal, and a reading of 100 ~ 120 VAC on the other terminal is obtained, remove both probes from the outlet.

6) Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other probe on the terminal that produced a reading of zero volts. The reading should be less than 1 ohm.

CAUTION! If the reading is more than one ohm, then the outlet is not adequately grounded.

7) If the above tests show the outlet is not properly grounded, the condition should be corrected (per Article 250 of the National Electrical Code) by a qualified electrician before the system is connected.

4.20 Alternate or Additional Ground

4.21 If the “third wire” AC ground can not practi-

cally be improved or if extreme motor noise or other disturbance causes system malfunction, or if local area lightning storms exist, a separate direct ground may be warranted.

4.22 Connect a separate earth ground from a cold water pipe or earth grounding rod directly to the FG screw terminal on the DK8/DK16 power supply. See Figure 4-5 of Section 100-816-204 (for STRATA DK8) or Figure 5-8 of Section 100-816- 205 (for STRATA DK16).

ations on how to configure a STRATA DK8/DK16 system, which can support a wide variety of stations and peripherals.

2 SYSTEM CAPACITY

2.00 Total System Capacity

2.01 The STRATA DK8/DK16 systems have a

modular design which allows them to support a number of station and CO line configurations. The main component of each system is the Key Service Unit. The DK8 KSU can have up to 10 stations and four CO lines. The DK16 Base Key Service Unit can have up to 12 stations and four CO lines. An Expansion Key Service Unit can be added to the DK16 to increase the station capacity to 20 and the CO line capacity to eight. Station and CO line configurations are shown in Table 3-A (for DK8) and Table 3-B (for DK16).

2.10 The DK8 Key Service Unit

2.11 Station and CO Lines. The DK8 Key Service

Unit comes standard with four digital telephone circuits (ports) and two CO line circuits (Table 3-C). An optional printed circuit board called the QCDU can be added to the KSU to provide one CO line circuit and two digital telephone circuits. A maximum of two QCDUs may be added to provide a total of four additional digital telephone circuits and two additional CO line circuits. Another optional printed circuit board called the QSTU can be added to the DK8 KSU to provide two standard telephone circuits.

2.12 Peripherals. The DK8 Key Service Unit can support a number of peripherals, which are not considered as stations and do not affect the maximum station and CO line capacities. A customersupplied Music-on-hold source, optional reserve power battery and charger, a customer-supplied emergency standard telephone for system power failure occurrences and an amplifier with speaker for paging and night ringing can all be connected to the Key Service Unit (Table 3-C). A relay contact is also provided to control one of the following

peripherals: Music-on-hold source, night bell, or page amplifier mute control.

2.20 The DK16 Base Key Service Unit

2.21 Station and CO Lines. The DK16 Base Key

Service Unit comes standard with eight digital telephone circuits (ports) and four CO line circuits (Table 3-D). An optional printed circuit board called the KSTU can be added to the unit to provide four standard telephone circuits (ports).

2.22 Peripherals. The DK16 Base Key Service Unit can support a number of peripherals, which are not considered as stations and do not affect the maximum station and CO line capacities. A customer-supplied Music-on-hold source, customer-supplied separate background music source, customer-supplied reserve power batteries, a customer-supplied emergency standard telephone for system power failure occurrences and an amplifier with speaker for paging and night ringing can all be connected to the Base Key Service Unit (Table 3-D). A relay contact is also provided to control one of the following peripherals: Music-on-hold source, night bell, or Page Amplifier mute control.

2.30 The DK16 Expansion Key Service Unit

2.31 Station and CO Lines. The optional DK16

Expansion Key Service Unit has four universal slots which can support a maximum of four CO lines and eight stations. Printed circuit boards (PCBs) that support CO lines and can be installed in the Expansion Unit are the PCOU and KCDU (Table 3-E). PCBs that can support stations and be installed in the Expansion Unit are the PDKU, PEKU, PSTU, PESU, and KCDU.

2.32 Peripherals. The Expansion Unit can support either a PIOU or PIOUS PCB, which both provide, among other features, Station Message Detail Recording (SMDR), an interface for a local programming terminal, and connectors for an internal modem (IMDU) for remote maintenance and administration (Table 3-F). Any device that connects to the PIOU or PIOUS should not be considered a station and does not affect the system's station capacity.

3 STATION CONSIDERATIONS

3.00 For configuration purposes, a station can be

considered as any device which is connected to a dedicated telephone circuit. Although the words "telephone" and "station" are often used synonymously and interchangeably in STRATA DK8/ DK16 documentation, devices other than telephones—such as Stand-alone Data Interface units (PDIU-DSs)—should also be considered as stations when configuring a system, because they require a dedicated telephone circuit. A station apparatus overview is shown in Table 3-G (for STRATA DK8) and Table 3-H (for STRATA DK16).

3.10 Telephone Circuit (Port) Types

3.11 There are three types of telephone circuits to

which stations can be connected: digital telephone circuits, electronic telephone circuits, and standard telephone circuits. All three types of circuits are available with the STRATA DK16. The STRATA DK8 does not support electronic telephone circuits.

3.20 Digital Telephone Circuit Connections

3.21 The STRATA DK8 Key Service Unit provides

four digital telephone circuits. The QCDU PCB provides two.

INSTALLATION-CONFIGURATION SECTION 100-816-203 MARCH 1993

NOTE: A maximum of two QCDU PCBs may be installed in the STRATA DK8.

3.22 The STRATA DK16 Base Key Service Unit and the PDKU PCB each provide eight digital telephone circuits. The KCDU PCB provides four.

NOTE: A maximum of two KCDU PCBs may be installed in the STRATA DK16. If a KCDU is installed, no other type of station PCB can be installed in the STRATA DK16.

3.23 The following devices can be connected to digital telephone circuits:

•

Digital Telephones (2000- and 1000-series):

Each digital telephone requires one circuit, and each digital telephone circuit can support a digital telephone.

•

Stand-alone Data Interface Units (PDIU-DS): Each PDIU-DS requires one circuit. Any digital telephone circuit, except for Circuit 8 on a PDKU1 (STRATA DK16), can support a PDIU-DS (see Note 1).

NOTES:

1. There are two versions of the PDKU: PDKU1 and PDKU2. The versions are identical, except that Circuits 1 ~ 8 on the PDKU2 can each support PDIU-DSs/ PDIU-DI, while only Circuits 1 ~ 7 on a PDKU1 can support PDIU-DSs or PDIUDIs. Also, PDIU1 does not support 2000series digital telephone continuous DTMF tones.

2. The Integrated Data Interface Unit (PDIUDI/PDIU-DI2) and the Add-on Module (ADM) do not require a dedicated circuit. They share a circuit with the telephone.

3. Only one option (PDIU-DI2 or ADM) can be installed on a 2000-series digital telephone.

• Digital Direct Station Selection Console (DDSS): (available with STRATA DK16 only) Each DDSS Console requires one circuit. DDSS Consoles can connect only to Circuit 8 in the Base Key Service Unit and Circuit 8 on a PDKU.

The KCDU cannot support a DDSS console.

• Digital Door Phone/Lock Control Box (DDCB): Each DDCB requires one circuit. DDCBs can only connect to Circuits 3 and 4 (Ports 02 and 03) in the STRATA DK8 Key Service Unit or Circuit 5 (Port 04) in the STRATA DK16 Base Key Service Unit, and Circuit 1 (Port

12) on either the PDKU or KCDU (STRATA DK16).

3.30 Electronic Telephone Circuit Connec-

tions (STRATA DK16 Only)

3.31 There are no electronic telephone circuits in

the Base Key Service Unit, and none can be added to it. However, either the PEKU PCB, which has eight electronic telephone circuits, or the PESU, which has four electronic telephone circuits, can be installed in the Expansion Key Service Unit. The following devices can be connected to electronic telephone circuits.

•

Electronic Telephones (6500-, 6000-, 3000-, 2000-series): An electronic telephone can be

connected to any electronic telephone circuit. One electronic telephone circuit is required per electronic telephone.

• Electronic Direct Station Selection Console (HDSS): The system will support only one HDSS console. The console must be connected to both Circuits 7 and 8 on the PEKU. The PESU will not support an HDSS Console.

• Alternate Background Music Source: The system will support an alternate Background Music source which can be heard over digital and electronic telephone speakers and external page speakers. This source can be connected to either Circuit 3 on a PEKU, Circuit 8 on a PESU, or Circuit 4 on a KSTU or PSTU PCB.

• Conference Amplifier: An amplifier for two CO line conferencing can be connected to Circuits 6 and 7 (Ports 17 and 18) on a PEKU or PESU.

3.40 Standard Telephone Circuit Options

3.41 In addition to supporting standard telephones,

each of the standard telephone circuits can support any one of a number of single-wire-pair devices, including voice mail/Auto Attendant devices and modems. The QSTU, which can be installed in the STRATA DK8 Key Service Unit, has two

3-8

INSTALLATION-CONFIGURATION

SECTION 100-816-203

MARCH 1993

standard telephone circuits. The KSTU, which can be installed in the STRATA DK16 Base Key Service Unit, has four standard telephone circuits; the PSTU, which can be installed in the DK16 Expansion Key Service Unit, has eight; and the PESU, which can also be installed in the DK16 Expansion Unit, has two (Circuits 1 and 2).

4 TELEPHONE UPGRADES

4.00 Digital and Electronic telephones can be

upgraded for a number of features; there are no upgrades for standard telephones. Each of these upgrades shares a circuit with the telephone that it is connected to and is not considered a station.

4.10 Digital Telephone Upgrades

4.11 Digital telephones can be upgraded with the

following subassemblies:

• Integrated Data Interface Unit (PDIU-DI/PDIU-

DI2): A Digital telephone can be upgraded with

a PDIU-DI/PDIU-DI2 to provide the telephone with data switching capabilities. 2000-series Digital Telephones use the PDIU-DI2, and 1000series Digital Telephones use the PDIU-DI. PDIU-DI2 cannot be installed on a telephone if ADM is installed.

• Add-on Module (ADM): A 2000-series Digital Telephone can be upgraded with an ADM to provide 20 Direct Station Selection buttons on STRATA DK16, or 10 DSS buttons, 8 speed dial buttons, one night transfer button and one all call page button on STRATA DK8. The 1000series Digital Telephone models cannot support ADMs. ADM cannot be installed on a telephone if PDIU-DI2 is installed.

• Off-hook Call Announce Upgrade (DVSU): A Digital telephone that must receive Off-hook Call Announce must be upgraded with a DVSU.

• Loud Ringing Bell/Headset Upgrade (HHEU): A digital telephone can be upgraded with an HHEU to provide a dual interface for the Loud Ringing Bell feature and/or a headset. (Simultaneously with PDIU-DI2 or ADM).

4.20 Electronic Telephone Upgrades

4.21 On STRATA DK16, electronic telephones

can be upgraded with the following subassemblies:

• Off-hook Call Announce Upgrade (HVSU2 or

HVSU/HVSI): An electronic telephone must be

upgraded with the HVSU2 subassembly or the combined HVSU/HVSI subassemblies to receive Off-hook Call Announce.

NOTE: A PEKU or PESU PCB that supports electronic telephones that must receive Off-hook Call Announce must be equipped with an EOCU.

• Loud Ringing Bell/Headset Upgrade (HHEU): An electronic telephone can be upgraded with an HHEU to provide a dual interface for the Loud Ringing Bell feature and a headset simultaneously.

5 CONFIGURATION EXAMPLES

5.00 The following provides an examples of how to

configure a STRATA DK8.

5.10 Strata DK8 - Example 1 (Smalll Retail

Store)

5.11 Customer Requirements. A store needs

two CO lines and four digital telephones.

5.12 Analysis. The store's system hardware re-

quirements are as follows:

• Two CO line circuits for the CO lines.

• Four digital telephone circuits for the digital telephones.

5.13 Conclusion. A standard Key Service Unit

would be adequate in this case. The unit's standard four digital telephone circuits and two CO line circuits could easily accommodate the store's needs and allow for future expansion.

5.20 Strata DK8 - Example 2 (Home/Office)

5.21 Customer Requirements. In addition to three

CO lines, a home/office needs five digital telephones (three of which will have PDIU-DIs), a modem, a door phone, one facsimilie machine, Music-on-hold and Telephone Set Background Music.

5.22 Analysis. The customer's requirements could

be broken down as follows:

3-9

INSTALLATION-CONFIGURATION SECTION 100-816-203 MARCH 1993

•

3 CO line circuits for the three CO lines

•

7 digital telephone circuits

one for each of the five digital telephones; the PDIU-DIs do not require dedicated circuits.

one for a digital door phone/lock control unit to support a door phone

one for the PDIU-DS connected to the modem

•

2 standard telephone circuits

one for the modem

one for the facsimilie machine

•

A music source for Music-on-hold and Background music can be connected to the Key Service Unit MOH RCA jacks.

5.23 Conclusion. Several optional PCBs in addition to the Key Service unit would be needed for the application. Two CO line circuits and four digital telephone circuits would be provided by the KSU. The third CO line circuit, as well as two digital telephone circuits would be provided by an optional QCDU. A second QCDU would be necessary to provide the seventh digital telephone circuit. An optional QSTU would provide the two standard telephone circuits. An optional QRCU would be needed for the Dual-tone Multi-frequency (DTMF) tones generated by the devices (modem and facsimilie machine) connected to the standard telephone lines.

5.30 The following provides an examples of how to configure a STRATA DK16.

5.40 Strata DK16 - Example 1 (Bank)

5.41 Customer Requirements. A bank needs two

CO lines and six digital telephones (three of which must be equipped with a PDIU-DI). It also wants to connect a printer to a PDIU-DS.

5.42 Analysis. The bank's system hardware requirements are as follows:

• Two CO line circuits for the two CO lines.

• Seven digital telephone circuits. Six for telephones and one for the PDIU-DS. (The PDIU-DIs do not require a dedicated circuit.)

5.50 Strata DK16 - Example 2 (Office/Warehouse)

5.51 Customer Requirements. In addition to five

CO lines, a small office-warehouse facility needs 11 digital telephones (three of which will have PDIU-DIs), two PDIU-DSs, a modem, a facsimile machine, conference capability, a door phone, one standard telephone, Music-on-hold, and an amplifier/speaker for paging.

5.52 Analysis. The customer's requirements could be broken down as follows:

•

14 digital telephone circuits

one for each of the 11 digital telephones; the PDIU-DIs do not require dedicated circuits.

one for each of the two PDIU-DSs

one for a digital door phone/lock control unit to support a door phone

•

3 standard telephone circuits

one for the modem

one for the facsimile machine

one for the standard telephone

•

A music source for Music-on-hold and an amplifier/speaker for paging could both be connected to the Key Service Unit RCA jacks.

•

A K4RCU would be needed for the Dual-tone Multi-frequency (DTMF) tones generated by the devices connected to the standard telephone circuits.

•

A PCOU would be needed for the fifth CO line.

5.53 Conclusion. An Expansion Key Service Unit in addition to the Base Key Service Unit would be needed for this application. The three standard telephone circuits could be contained on the optional KSTU PCB in the Base Unit. However, a PDKU installed in the Expansion Unit would be required for six of the 14 digital telephone circuits. The Expansion Unit would also be needed for the PCOU. The optional K4RCU, along with the music source and the page/amplifier, as noted earlier, could be connected to the Base Unit.

6 CONFIGURATION WORKSHEETS

5.43 Conclusion. A standard Base Key Service

Unit would be adequate in this case. The unit's standard eight digital telephone circuits and four CO line circuits could easily accommodate the bank's needs.

6.00 Worksheets are provided in this chapter to help configure the system.

1.00 This chapter provides the instructions nec-

essary to mount the STRATA DK8 Key Service Unit. Instructions are also provided on how to remove and replace the power supply.

2 KEY SERVICE UNIT MOUNTING

2.00 Mounting Surface Considerations

2.01 The Key Service Unit (KSU) is designed to be

mounted on a wall or other vertical surface. It is recommended to use the method shown in Figure 4-1 (see Note). See Figure 4-2 for DK8 KSU physical dimensions.

NOTE: Install screws first to the hard board, and then

secure the hard board to the wall, making certain that screws are aligned with studs.

2.10 Mounting Preparation

1) Loosen the screws on the front cover of the Key Service Unit, and remove the cover (Figure 4-2).

2) Move the SW1 RAM Storage Battery jumper plug strap on the motherboard to the ON position (Figure 4-5).

3) If the DK8 is less than one mile from the central office (or PBX), set the CO line PAD switches, SW101 and SW201, to the PAD position to provide a 3db level loss to avoid excessive loudness.

4) Install all optional PCBs per Paragraph 5.

2.20 Mounting the Key Service Unit

1) Make sure the power supply switch is turned OFF.

2) Place the Key Service Unit on the desired location on the mounting surface and mark the location of the four screw holes (there is one on each corner). See Figures 4-1 and 4-2.

NOTE: Make sure the location of the Key Service Unit meets the minimum clearance requirements specified in Figure 2-1 in Chapter 2.

3) Drill holes on these marks.

4) Secure screws approximately two thirds of the way into the top two holes on the mounting surface.

5) Hang the unit from the top two screws and then secure the screws completely into the mounting surface.

6) Finish securing the unit to the mounting surface by completely screwing the bottom two screws into the wall.

7) Ground system according to Chapter 2, Paragraph 4.

8) Connect applicable wiring (modular CO line cords, 25-pair amphenol connector cable, etc.) to the Key Service Unit. Route the wiring as shown in Figure 4-4, and then fasten wiring to the unit with the tie wraps that come with the Key Service Unit. (See Section 100-816-208, for additional wiring information.)

NOTE: Figure 4-4 shows cables routed to the right; they may also be routed to the left, depending on the location of the MDF.

9) If the Reserve Power Battery and Charger (HPFB) is going to be installed, refer now to Paragraph 2.30. If not, proceed to Step 10.

10) Plug the AC power cable into an outlet and then turn ON the DC power supply switch.

11) Reinstall the front cover onto the Key Service Unit.

2.30 Installing the Reserve Power Battery and Charger (HPFB) (Figure 4-4)

1) Place the HPFU directly above the DK8 KSU.

2) Mark the location of the two screw holes, then drill holes.

3) Screw the two screws two-thirds into the mounting surface.

4) Hang the HFPU on the screws then tighten the screws into the mounting surface.

5) Plug the first HPFU connector into BATT connector on the right side of the KSU.

6) Connect a ground wire from the HPFB "FG" screw to the DK8 QPSU8 screw labeled "HPFB6." The ground wire can be fed through the opening by the AC power cord (see Figure 4-3).

NOTE: The DK8 should be plugged into AC power and the DC power switch should be turned on. The HFPU will not start to operate if AC power is not available during the initial installation.

7) The 24V LED on the HPFU should light. If it does not light, press the battery OFF switch with a pencil point or other small-tipped object.

8) Dress and tie-wrap the HPFU cables per Figure 4-4.

9) To mount a second HPFU, repeat steps 1~4, then plug the second HPFU connector in the first HPFU and connect an FG wire between each HPFB FG screw.

10) To test the HPFU, remove the DK8 AC plug from the AC outlet. The DK8 AC LED will go out but the DK8 DC LED remains on, also the system remains in normal working order and the HPFU 24V LED remains on.

11) If it is desired to turn off the HPFU (after loss of AC power), use a pencil or other sharp object to press the Battery Off switch.

CAUTION! Once the HPFU is turned off or unplugged (During AC power loss) it will not operate again until AC power is restored to the DK8 KSU.

4 DK8 POWER FAILURE EMERGENCY

TRANSFER OPTION

4.00 A dedicated standard telephone can be con-

nected to the Power Failure Transfer Interface (PF1) on the Key Service Unit to provide power failure backup. During normal operation, this telephone cannot be used—it does not count as a station; so it does not reduce the system's 10 maximum station capacity. But if there is a power failure, the telephone will automatically be connected to CO line 1. When power is restored, the system will automatically resume with its normal station and CO line assignments, and the dedicated telephone will become inoperative again.

4.10 DK8 Power Failure Emergency Transfer

Installation. Install the dedicated emergency stan-

dard telephone as follows (see Figure 4-6):

1) Connect a standard telephone to the PF1 connector in the Base Unit.

4.20 DK8 Power Failure Emergency Transfer Test.

1) Turn the system power switch off.

4) Plug the AC cable into the CN1 connector on the power supply (Figure 4-5).

2) Lift the emergency standard telephone handset, and verify that there is CO dial tone.

call and three parties on the second simultaneous conference.

6.20 PCB Option Considerations

6.21 PCBs may be configured for a variety of

hardware and software options. Hardware options are defined as either internal (generally related to optional PCB subassemblies) or external (related to connection of peripheral equipment such as background music, voice mail, etc). Hardware and software options for each PCB are identified in the individual PCB installation procedures in this chapter.

6.22 PCB Hardware Options. Each PCB must be configured for the applicable hardware options prior to installation of the PCB. Configuration instructions for internal hardware options are provided in the individual PCB installation procedures in this chapter. Configuration instructions for external hardware options are provided in Peripheral Installation, Section 100-816-207.

6.10 KSU Option PCBs

6.11 The KSU can support up to five optional

printed circuit boards (PCBs) (Figure 4-7): it can support a maximum of two QCDUs, each of which provides one CO line circuit and two digital telephone circuits; a QSTU which provides two standard telephone circuits (ports); a QRCU which provides three circuits to receive DTMF tones (required for DISA and devices connected to QSTUs), and three circuits to detect busy tone (required for the ABR feature); and a QSMU which provides a port for either a Station Message Detail Recording (SMDR) device or a maintenance terminal or modem (System Program 10-3, LED 04) selects the function of the port — SMDR or TTY).

6.12 The KSU does not come from the factory with any option PCBs installed. Each of the option PCBs listed above must be installed in specific locations as described later in this chapter.

NOTE: QCNU is a standard factory installed piggyback PCB which provides conference circuits allowing two simultaneous conferences with four of these parties on the first conference

6.23 PCB Software Options. PCBs are configured for software options through programming, after installation of the PCBs in the KSU. A programming overview for each PCB is provided in the individual PCB installation procedures in this chapter. Refer to the Programming Procedures, Section 100-816-300, for detailed programming instructions.

7.10 QCDU Configuration

7.11 The QCDU may have to be configured to

control excessive loudness if the system is close to a CO or installed behind a PBX telephone system. It does not have to be configured for anything else. The decibel (db) PAD switch, SW101 controls the loudness by providing a 3 db signal level drop to, or from, the PBX or CO when set to the PAD position. The switch comes from the factory set at NOR (for normal) meaning no PAD loss.

7.20 QCDU Installation Procedure

7.21 Install the QCDU in accordance with the

following steps (Figure 4-7):

1) Remove the PCB from its protective packaging.

2) If the system is located within one mile of the CO or PBX telephone system, set db PAD switch SW101 to the PAD position.

3) Make sure that the power supply switch is OFF.

PART II. DK16 PRINTED CIRCUIT BOARD

INSTALLATION

4 GENERAL

4.01 This chapter provides procedures for installa-

tion of STRATA DK16 system printed circuit boards (PCBs) into the Base and Expansion units. This includes installation instructions, optional configuration information, and wiring and programming considerations for each PCB.

4.02 Be sure the power supply has been tested, and the ground has been checked. (See Chapter 5, Section I for the power supply and Chapter 3 for grounding.)

4.03 It is recommended to install the Base Unit option PCBs K4RCU and/or KSTU before mounting the Base KSU on the wall.

4.04 Begin Expansion PCB installation only after completion of Expansion Unit installation (see Chapter 5, Section I).

5 DK16 PCB INSTALLATION

CONSIDERATIONS

5.01 The STRATA DK16 Base Unit comes stan-

dard with eight digital telephone circuits (ports) and four CO line circuits. The digital circuits are integrated into the motherboard, and the CO line circuits are on the KCOU which is attached to the P6 and P7 connectors on the motherboard. The common control unit, like the digital telephone circuits, is built into the motherboard.

5.10 DK16 Base Unit PCBs

5.11 The Base Unit can support an optional KSTU

printed circuit board (PCB) which provides four standard telephone circuits (ports). In addition, a K4RCU PCB can be installed to receive DTMF tones, and detect busy tone for Automatic Busy Redial (ABR) operation.

5.20 DK16 Expansion Unit PCBs

5.21 The Expansion Unit can support a number of

PCBs: it can support a PCOU which provides four

CO line circuits; one or two KCDUs which provide two CO line circuits and four digital telephone circuits (ports); a PDKU which provides eight digital telephone circuits (ports); a PEKU which provides eight electronic telephone circuits (ports); a PESU which provides two standard and four electronic telephone circuits (ports); a PSTU which provides eight standard telephone circuits (ports); and a PIOU or PIOUS which both provide a port for a Station Message Detail Recording (SMDR) device, an interface for remote maintenance, and relay control options.

5.22 The DK16 Expansion Unit does not come from the factory with any PCBs installed. Any of the PCBs listed above can fit into any of the unit's four universal slots; however, it is recommended that PCBs that support electronic or digital telephones be installed into Slots 04 and 05, because Slots 06 and 07 cannot support Off-hook Call Announce or Data Interface Units (DIUs).

Recommended PCB slot assignments:

•

KCDU — Slot 04 and 05 (2 maximum)

•

PDKU, PEKU, PESU, PSTU — Slot 04 (1 maximum, cannot be installed with KCDU.)

•

PCOU — Slot 05 (1 maximum, cannot be installed with KCDU.)

•

PIOU/PIOUS — Slot 06 (1 maximum)

5.30 PCB Option Considerations

5.31 PCBs may be configured for a variety of

5.32 PCB Hardware Options. Each PCB must be configured for the applicable hardware options prior to installation of the PCB. Configuration instructions for internal hardware options are provided in the individual PCB installation procedures in this chapter. Configuration instructions for external hardware options are provided in Peripheral Installation, Section 100-816-207.

5-13

INSTALLATION-DK 16 KSU & PCB SECTION 100-816-205 MARCH 1993

5.33 PCB Software Options. PCBs are configured for software options through programming, after installation of the PCBs in the KSU. A programming overview for each PCB is provided in the individual PCB installation procedures in this chapter. Refer to the Programming Procedures, Section 100-816-300, for detailed programming instructions.

5.40 PCB Installation/Power Supply Considerations

5.41 Whenever removing or installing PCBs it is

recommended that the power supply be OFF.

6 BASE UNIT STANDARD TELEPHONE

INTERFACE UNIT (KSTU)

6.00 General

6.01 The optional KSTU provides four standard

telephone circuits and it can only be installed in the Base Unit. The KSTU supports the two-wire devices such as standard telephones, Auto Attendant devices, voice mail machines, and facsimile machines. The KSTU can also support an alternate Background Music (BGM) source on circuit 4.

NOTE: For the system to recognize the Dual-Tone Multi-Frequency (DTMF) tones generated by standard telephones (or any other device connected to a KSTU port), a K4RCU must be installed in the Base Unit.

6.02 The KSTU is shown in Figure 5-11 and its connectors and controls are described in Table 5A.

6.10 KSTU Configuration

6.11 The KSTU only has to be configured for the

ring generator voltage level, nothing else. Before installing the KSTU in the Base Unit, set the SW540 ring generator to 130V P-P or 190V P-P. Most standard telephones and two-wire devices require 190; however, some devices may experience ringtrip at 190, and should be set at 130.

6.20 KSTU Installation Procedure
