DHS General Description

System Technology

The DHS product line incorporates state of the art digital technology for voice switching and call processing utilizing Pulse Code Modulation and Time Division Multiplexing (PCM/TDM). The DHS family is engineered to allow migration of the DHS digital terminals and terminal accessories throughout the entire product line. ISDN-like, 2B+D technology complements the system architecture and capabilities. On one industry standard twisted pair, key telephones perform all system functions and voice communications. Some additional features of the DHS include:



A non-blocking switch, with no loss or degradation of voice signals.



Stored-Program Control (SPC), utilizing a 16-bit, 8 MHz microprocessor.



Memory consists of 512 KB of Read Only Memory (ROM) and 128 KB of Random Access Memory (RAM).

When an analog device interface is required, a 2-Port Central Office (CO) Module may be connected to any one digital station port. The 2B+D technology allows the DHS to split one digital key telephone port voice channel (B1) and the second voice channel (B2) to provide two independent SLT-type device interfaces.

The 2-Port CO Module may be expanded with the 2-Port Analog Expansion (in the 2-Port CO Module housing).

The 2-Port CO Module and 2-Port Analog Expansion each require one dedicated digital station port.

Power Supply

The power supply circuitry of the DHS incorporates a linear design transformer with a choice of input voltage taps. The transformer primary windings are shipped wired for 117V AC applications; a factory insulated tap wire may alternatively be connected for 230V AC applications. Since the power supply is linear in design the output voltage varies between 21.6 and 32V DC depending on load and stability of the input voltage. The output voltage is delivered to the CPU board for distribution and rectified there for logic and control voltages.

Two fuses are equipped on the power supply board, one for AC input over-voltage protection and one for DC output over-voltage protection. A Double Pole Double Throw (DPDT) switch is accessible from outside of the KSU when the KSU cover is in place. The DPDT switch will simultaneously switch AC input and DC output circuits ON and OFF.

In the event battery backup operation is desired and equipped via the optional DHS Battery Charging Unit (BCU), the KSU switch may be used to switch OFF/ON power from both sources.

The power supply wiring harness is equipped with a mate-n-lock connector on the DC output for connection of the DHS BCU. When equipped, the BCU will maintain complete system operation during commercial power outages. A current draw/configuration chart is included in this document for assistance in selecting the appropriate batteries for use in the BCU. Please consult the BCU manual for installation precautions and proper battery installation.

Central Processor Unit (CPU)

The CPU board is standard in the KSU. This board contains all circuitry required to control the fully-equipped DHS . Three bus connectors are provided where the station/CO line interface 3 x 8 module and 6-Port CO Module are connected. The Option Module connector and Standard MOH Module connector are also located on the CPU board. All digital voice switching and call process data switching is accomplished on the CPU board.

3 x 8 Module

The 3 x 8 module provides interface of three loop-start CO lines and eight DHS key telephones.

Each CO line circuit incorporates over-voltage protection, ring detector, loop detector, loop/pulse-dial relay, current sink circuit, coupling/isolation transformer (impedance 600:Ohms), hybrid circuit and combo (CODEC and filter) polarity guard circuit and radio frequency noise filter.

Each digital key telephone port is comprised of a proprietary transceiver designed using ISDN type 2B+D architecture.

Physical connection of stations and CO lines to the 3 x 8 module is made through one male 25-pair, amphenol-type connector to the Main Distribution Frame (MDF). Station power and signaling to the digital key telephones are provided via a single twisted pair from the 3 x 8 module.

Preparation for DHS Installation 2-23

General Site Considerations

The first step of DHS installation, is to locate an acceptable site for the common equipment (KSUs, boards, etc.). When locating a mounting site for the KSUs, the following points must be considered:



KSUs are designed for wall mounting and should not be mounted directly to a masonry or plasterboard wall. It is recommended that 1/2 in. plywood backboard be firmly mounted to the wall, and the KSU and MDF be mounted to the backboard.



The location must have access to a dedicated 117V AC (±10%), 60 Hz, single-phase circuit with a circuit breaker or fuse rated at 15 amps. A 3-wire parallel blade grounded outlet should be within approximately 6 feet of the lower left rear of the KSU mounting.



The location must have access to a good earth ground, such as a metallic cold water pipe without non-metallic joints. The ground source should be located as close as possible to the system.



The system should be located in an area that is well ventilated with a recommended temperature range of 68-78° F and a relative humidity range of 5-60% (non condensing).



The system should be located within 25 ft. of the telephone company’s termination point. Also, the location should be within the prescribed station loop lengths for all keysets and terminals. If existing cabling is used, its location and conduits should be considered. Station wiring should be in the building. Station ports are not designed for installation outside of the building.



Protection from flooding, flammable materials, excessive dust and vibration.



The site should be away from radio transmitting equipment, arc-welding devices, copying machines and other electrical equipment capable of generating electrical interferences.



Operation of this equipment in a residential area is likely to cause interference. In which case the user, at his own expense, is required to take any necessary measures to correct the interference.

Necessary Tools and Supplies

To make installation easier, consult the following pages when preparing to install the system.

Tools

The following tools are recommended to install your DHS system. Others may be needed for certain troubleshooting procedures.



Use unshielded, twisted multi-pair (three-pair minimum recommended) cable to run from the MDF to all station instruments (key telephone and single-line DTMF telephones). Digital key telephones only need one twisted pair to operate.

Use shielded cable if RFI/EFI is expected.

2-24 Preparation for DHS Installation



Six conductor modular jack assemblies for all station instruments (recommended).



Standard punch-down terminal block(s), 66M1-50 type, as required.

Verify On-Site Equipment

Once the equipment installation site is identified and a dedicated AC outlet, earth ground, adequate lighting and ventilation are available, verify that all equipment required is on-site and was not damaged during shipping:



Unpacking the KSU - The Key Service Unit is shipped in its own protective carton and contains the following:



Basic KSU



One mounting template



One System Installation & Maintenance Manual

Open the carton and verify that all items are complete and undamaged. Remove all packing material and store for future use in the event that return shipment is required. This should be performed at the installer’s office with a 48-hour burn-in period prior to installation.



Check that the type and quantity of boards received is correct. DO NOT unpack the individual boards at this time.



Verify optional equipment is received and is in good condition.



Verify that a Power Line Surge Protector is on-site.

If any equipment is damaged or missing, notify the appropriate personnel to correct the situation.

DHS Installation

1. Backboard MDF Installation

A wooden backboard is recommended for all installations and must be installed when the location has masonry or plasterboard walls. A 1/2 in. plywood material is sufficient for most installations.

1. Mount the backboard at a convenient height, about 3 ft. above the floor. It can be bolted in various places to distribute the weight of the system.

2. Space should be available on the bottom side of the backboard for the MDF cabling and for optional equipment such as a music source and battery backup.

3. It is recommended that the location of each major item be roughly sketched on the backboard as an installation layout.

4. Locate the Telco-provided CO/Centrex lines at the demarc and extend them to the MDF location.

2-26 DHS Installation

2. KSU Grounding

To ensure that the system will operate properly, a good earth ground is recommended. The Telco protector ground terminal or a metallic COLD water pipe will usually provide a reliable ground path. If cold water pipe is used, carefully check that the pipe does not contain insulated joints that could isolate the ground. In the absence of the cold water pipe, a ground rod or other source may be used. A No. 8 AWG copper wire should be used between the ground source and the KSU.

The ground wire should be kept as short as possible and can be connected to the ground lug located on the bottom of the KSU. Check your local grounding regulations before installing the ground wire.

Voltage Surge/Spike Protection

To reduce the effects of AC voltage surges and spikes that may cause system malfunctions, false logic, and/or damage to the electronic components, it is recommended that a separately sourced surge/spike protector be installed. Check the manufacturer's specifications to ensure that the device meets the following requirements:



The power cord should not be used with a 3-wire to 2-wire plug adapter.



A power line surge protector should be used to protect the power supply from electrical surges. The surge protector should be installed in accordance with the manufacturer's instructions and applicable local electrical codes.



Clamp voltage transients at 300V within 5 nsec. when exposed to wave-forms as described in the ANSI/IEEE Standard C62.41-1980 (IEEE 587).



Reduce RFI/EMI noise by at least 20 dB at frequencies between 5 kHz and 30 MHz.

3. Battery Backup - System

External batteries may be connected to the KSU via the optional Starplus VC61101 Battery Charging Unit (BCU). This unit may be equipped with batteries sized to meet the particular customer requirements. The approximate time, in back-up hours, is located in Table 2-11. In the event of a commercial power outage, the BCU will provide the necessary system voltage (24V) to allow full feature key telephone operation until AC power is restored or the battery voltage reaches minimum voltage thresholds and is automatically disconnected to avoid battery damage. This threshold is approximately 21 to 21.5V. The amount of system battery operation time is dependent on several factors:



Number and type of key telephones installed



System traffic load



Age of external batteries



Equipment Room Temperature



Amp/Hour rating of external batteries



Recovery time since last AC power interruption

The Starplus VC61106 BCU is designed for use with the DHS system. Follow the instructions supplied with the BCU to install batteries in that unit. Consult Table 2-11 for system operating current draw to select the right battery size for the desired back up duration.

Do not mix batteries of different sizes or from different manufacturers in this product (applies to products employing more than one user-replaceable, secondary battery).

4. KSU Installation

The KSU is designed for wall mounting only. The KSU should NOT be mounted directly on a masonry surface. If the KSU is to be mounted on a masonry surface, a wooden backboard of sufficient size should be attached to the wall and the KSU mounted on the backboard.

1. Using the mounting template as a guide, mark the 2 mounting screws locations on the MDF backboard.

2. Pre-drill 2 screw holes and install 2 pan-head No. 10 screws into the backboard. The screw heads should protrude about 1/4-in. from the backboard plywood surface.

2-28 DHS Installation

KSU power transformer (where the KSU AC power cord is located) is positioned in the upper left corner. The power switch and Power/Heartbeat LED are positioned at the left side of the KSU toward the bottom.

It is very important that the KSU be correctly mounted to allow proper power supply heat dissipation.

The cable is then routed out of the KSU through an opening at the lower left of the KSU housing. A cable restraint clamp is provided and may be used to secure cables exiting the KSU. The 25-pair cable is then terminated on a punch-down terminal block on the MDF. Refer to Figure 2-19: Wiring Designations for 3 x 8 Modules.

The 3 x 8 module is installed to expand system capacity and is housed in the KSU in stacking fashion over the initial 3 x 8 module. Three 3 x 8 modules maximum can be installed in the KSU. The 3 x 8 module is shipped with four stand-off mounting posts. Follow these steps when installing a 3 x 8 module:

1. Be sure that KSU power is turned OFF.

2. Remove the KSU cover.

3. Connect grounded wrist strap to a suitable earth ground.

4. Locate the screws used to secure the 3 x 8 module or 6-Port CO Module.

The 6-Port CO Module must be installed in the last available expansion bus connector on the CPU Module. That is, if a 6-Port CO Module is installed on (JP3) a 3 x 8 module will not function if installed on (JP4). So, if a 3 x 8 module is added after a 6-Port CO Module was previously added, the 6-Port CO Module must be removed from (JP3), the new 3 x 8 module installed to (JP3) and the 6-Port CO Module reinstalled onto (JP4).

6-Port CO Module

The 6-Port CO Module is installed to increase system capacity of CO lines. The 6-Port CO Module is shipped with two 6-conductor cords, two surface-mount modular jacks and four stand-off posts. Regardless of how many 3 x 8 modules are installed, only one 6-Port CO Module may be installed. The 6-Port CO Module must be the last module installed. For example, if a 6-Port CO Module is first installed as the first Expansion Module (JP3), and a 3 x 8 module is then installed, the 6-Port CO Module must be moved to the last expansion position (JP4).

Figure 2-14: 6-Port CO Module

Follow these steps when installing the 6-Port CO Module:

1. Be sure that KSU power is turned OFF, and the KSU cover is removed.

2. Connect grounded wrist strap to a suitable earth ground.

3. Locate the screws that secure the 3 x 8 module already in place, and remove one of the module securing screws only so the existing board stays in place. Retain the removed screw.

4. Insert one of the supplied stand-off posts into the screw position where the screw from Step 3 was removed.

5. Tighten securely by hand, finish tightening using a small hand tool. It is very important not to over-tighten any screw or stand-off post as damage to the board may occur.

6. Repeat Steps 3 through 5 until all module screws are replaced with stand-off posts.

6. Terminating Connections

3 x 8 Module(s)

1. The CO line connections (as well as station connections) are made to the 3 x 8 Standard Module and Expansion Module(s) via the 25-pair connector located along the bottom edge of the installed module. Refer to Figure 2-19: Wiring Designations for

3 x 8 Modules.

2. Once the 25-pair cable is terminated on an industry standard 66M1-50 block, crossconnect (jumper wire) should be used to extend the CO line pair from the terminal block to the Telco Demarcation block.

DHS Installation 2-37

Figure 2-19: Wiring Designations for 3 x 8 Modules

6-Port CO Module

1. CO line interface to the 6-Port CO Module is made through two RJ25 type modular connectors on the 6-Port CO Module located along the bottom edge of the installed module. CO line ports (1-3) of the 6-Port CO Module are connected through RJ25 connector CO 1-3 (positioned toward the left/center of the installed module) and CO line ports (4-6) of the 6-Port CO Module are connected through RJ25 connector CO 46 (positioned toward the right/center of the installed module).

2. The 6-Port CO Module is shipped with two 3-pair line cords and two 3-pair terminal blocks for connection on the MDF. Once terminated, the individual pairs of the 3-pair terminal blocks are extended to the Telco Demarcation block. Plan to use at least on pair of bridging clips for each CO line connected so that service of any one specific CO line is simplified.

Conditions



It is the installer’s responsibility to assure that CO line connections are made in such a way that proper CO Hunting will sequence from the first CO line button to the last, in order on key telephones.



Typically, the Telco service provider provides lightning protection on the premise at the service entrance.



Test each CO Line at the MDF for dial tone, correct ringing sequence, Telco number assignment and polarity.

If incoming CO lines hunt from a main telephone number and are also used for outgoing (both-way CO line) service, always prioritize the incoming line order so that the last choice incoming trunks appear on the higher number CO line positions. This is because the system automatically selects idle trunks for outgoing calls, by searching from CO line 12, to CO line 11, and so on to CO line 1. This technique may avoid a head-on or glare condition where a user trying to place an outgoing call inadvertently answers a ringing line.

DHS Installation 2-39

7. Station Cabling

Floor plans should be developed to aid in proper station cabling in a star (home run) configuration from the KSU. The cables are run from the station locations to the STN block at the MDF.

Both ends of each cable should be labeled with the station's circuit number. The circuit number designates the station port position in the KSU.

When the system is initialized, the intercom numbers are assigned in order from Port- 1 (intercom number 10) to Port-24 (intercom number 33) as each Module is installed. Refer to Figure 2-19: Wiring Designations for 3 x 8 Modules.

Running Cable

From the MDF location, run unshielded, 3-pair (6-conductor) twisted cable to all key telephone locations and DTMF single-line telephone locations.

Use shielded cable if RFI/EFI is expected.

Follow these guidelines:



Install proper type cable for the application according to the National Electrical Code and local building codes.



Avoid cable runs parallel to fluorescent light fixtures or AC lines not in conduit. If these obstacles are unavoidable, run the cables across them at right angles.



Do not run station cables inside electrical conduit already occupied by AC wiring. (To do so is a violation of the National Electrical Code).



Do not run station cables near equipment with electric motors or through strong magnetic fields, such as those generated by large copy machines, arc welding equipment, heavy motors, etc.



Do not place station cables where they can be stepped on or where they can be rolled over by office furniture.



If using multi-pair (25-pair) cable runs to multiple station locations do not include AC ringing single-line sets, AC-ringing auxiliary equipment, or CO lines in a cable being used for key telephones. Key telephones should always be isolated in separate dedicated cable runs.



Do not exceed the measurements for the station cable lengths (using 26AWG wire) listed in Table 2-6: Maximum Cable Length.

It is recommended that a min imum of 3-pair cable and a minimum of 4-condu ctor modular jacks be used for all station connections.

2-40 DHS Installation

Terminating Cables at Station Locations

At each station location, terminate station cables on 4-conductor modular jack assemblies. Although only one pair is required for key telephone operation, the second pair is wired through to the ADP jack for a variety of applications at the desktop. For exception, refer to Table 2-13 .

Table 2-13: Station Location Cable Terminations

Cable Conductor Jack Wire Color Designation

Orange/White Yellow ADP Jack Ring lead

Do not mount the modular jack assemblies on the wall at this time. They will be wall mounted later when the station instruments are installed.

Since the digital station equipment is not polarity sensitive, reversing the digital telephone pair has no affect on operation. The Station Interface circuits are current-limited and are not fused.

8. Key Telephones Installation

Key telephones may be mounted with three different orientations: Low Profile Desk Mount, High Profile Desk Mount or Wall Mounted. Packaged inside each key telephone carton are the following components:



Key telephone

Large base-wedge mount assembly

The two wedge mount assemblies (large and small) are affixed at the factory. This configuration is used for High Profile Desk Mounting.

Remove the components from the carton and determine which mounting components are required. Most telephones are installed with both mounting wedges.

DHS Installation 2-41

High Profile Mount

For the High Profile Mounted position, reference the illustration below and attach the Base Mount wedges.

Figure 2-20: High Profile Mount

1. The small wedge is always used for the various telephone mounting positions.

2. The small wedge has locking tabs at one end and hooks at the other end used in a hinging fashion.

Wall Mount

When the telephone is to be Wall Mounted:

Figure 2-21: Wall Mount

1. Remove the two small screws that secure the small and large wedges together.

2. Store the larger wedge for possible use later (the large wedge is not used when wall mounting the key telephone).

2-42 DHS Installation

3. Position the smaller wedge as in the illustration at the right for wall mounting. Once in position, the smaller wedge and key telephone bottom housing provide for standard 630 type wall mount wall jacks.

Low Profile Mount

When the key telephone is to be desk mounted in the Low Profile position:

Figure 2-22: Low Profile Mount

1. Remove the two small screws that secure the small and large wedges together.

2. Store the larger wedge for possible use later (the large wedge is not used when mounting the key telephone in the Low Profile position).

3. Position the smaller wedge as illustrated below.

When using the Low Profile mounting position, it is important that the line cord be channeled through the slots in the telephone bottom housing, such that the smaller wedge locks them in place when in position.

Key Telephone Modular Jacks

Each key telephone has two modular jack connectors on the underside of the instrument. Both are located in a recessed connector cavity. When the telephone is held so that the rubber anti-skid feet are downward (no mounting wedge installed), the modular jacks face one another in the cavity. The modular jack at the left side of the cavity is theADP connector and may be connected to an analog device at the desktop. The ADP jack is only active when connected for operation at the MDF. The modular jack at the right side of the cavity is the KSU jack and should be connected to the wall jack and station cabling for connection to the system KSU (refer to Figure 2-23: Key Telephone Modular Jack Locations).

8. Press the Soft Button labeled Save to record the selection.

9. Press Clear to exit the Programming Mode.

9. SMDR/SMDA Output Device

The output device or the Station Message Detail Recording (SMDR) must meet the requirements and match the RS232C pin-out described below. The Option Module is required for SMDR operation.



The SMDR port baud rate is programmable from 110 to 19,200 BPS.



The Data Format is: 8 data bits, 1 stop bit, No parity bit.



Connection of the SMDR serial port to a computer for call accounting is often relatively simple, since a straight-through cable will typically mate the devices.



The SMDR serial port output is one way to the printer or other call accounting device.

The KSU end is considered DCE and printer or call accounting device is DTE.

KSU Connection

To connect an output device to the KSU:

1. Match the baud rates on the output device and the system.

2. Turn ON the AC power to both the device and the system before connecting the RS232C cable to Port-2 on the KSU. This prevents any electrical surges from being transmitted by the interface.

The RS232C cable connecting the SMDR device to the KSU must not exceed 50 ft. in length.

3. Carefully connect the RS232C DB-9 male end of the interface cable from the device to the SMDR RS232C DB-9 female connector located at the bottom edge toward the left of the Option Module.

10. Connecting and Programming Caller ID

The purpose of this service is to provide calling party identification to the dialed party. This information can be the calling party’s phone number, name, or a combination of this information. The information is delivered in between the first and second ring. The system can use this information to: Provide LCD information to stations receiving calls, maintain a list of unanswered calls for call back via the caller ID information.

When Incoming Caller ID is to be used with the DHS it is necessary to use the caller ID box. The caller ID box must be connected to the DHS system ICLID/PC Programming port using the Caller ID Cable. The caller ID box collects data at each CO line to be used for Incoming Caller ID and passes the data to the DHS system for processing. Each DHS CO line port must be programmed for the associated caller ID box port in customer database programming.

The caller ID box module is connected to the DHS system via the ICLID/PC programming port on the Option Module. Consequently, the PC programming port cannot then be used for PC-based programming and Incoming Caller ID data collection simultaneously. When all hardware connections are complete, adjust the caller ID box option switches for 1200 BPS operation. Program the DHS system PC Programming port for 1200 BPS operation. A proprietary cable can be ordered (refer to Table 2-5 ), or you can use a standard null modem.

11. External Paging Equipment (Optional)

The system provides a one way paging output at the KSU from the Option Module when installed. An 1/8 in. phono jack (refer to Figure 2-25) labeled J3 EXT PAGE is provided for connection to an external paging amplifier. The input specifications for the external paging equipment should accept a 600 ohm and 0 dBm interface.

Figure 2-25: 1/8 in. Phono Jack

Installation

Install the external paging equipment as follows:

1. Cut a length of shielded cable to run from the amplifier to the KSU.

2. Attach a 1/8 in. male phono plug to one end of the cable.

3. Connect the other end of the cable to the high impedance input according to the manufacturer’s instructions.

4. Connect the paging speaker(s) to the amplifier using speaker cable.

5. Plug in the amplifier's AC power cord. (DO NOT use the same AC outlet being used for

the KSU).

6. Insert the 1/8 in. phono plug into the jack labeled EXT. PAGE located on the bottom edge of the installed Option Module. The Ext. Page phono jack on the Option Module is the center-right phono plug (refer to Figure 2-26: External Paging Equipment

Installation).

7. Set the paging amplifier's volume control to the lowest setting and turn ON the external amplifier.

8. From a station location, make a page by lifting the handset, and dialing [F] + [501], the external page feature code.

9. Adjust the amplifier to the desired level while announcing the page.

10. PAGE VOL may be adjusted to lower the output signal in the event it is to strong for the connected amplifier input (over-driving input).

2-48 DHS Installation

Page Volume

External Page

Figure 2-26: External Paging Equipment Installation

Conditions



If the one-way paging equipment requires DTMF signaling from the key telephone, then an unused CO Line should be dedicated for proper page interface.



For Talk-back Paging or Multi-zone External Paging, the manufacturer recommends using a vacant CO line port for best operation.



A 600 ohm interface is provided on every CO line; therefore, any available CO line may be used for paging.



Since all CO line dialing is subject to toll restriction, a CO line port will not connect the station's audio until at least one DTMF digit is dialed.



It may be necessary to assign the CO line being used for paging as a PBX type trunk with one-digit or two-digit access. Therefore, normally toll restricted extensions may still make external pages, without being restricted.

DHS Installation 2-49

12. External Music Source

The Basic KSU is shipped with the Standard MOH/BGM Module. This module is located on a stand-off post toward the upper right corner of the CPU Module when viewing the installed KSU. The module provides a 1/8 in. phono jack (refer to Figure 2-25: 1/8 in. Phono

Jack) labeled JK1 MOH JACK for direct connection to an external music source. The

system music input impedance is 2 ohms. A trim Potentiometer (POT) is also provided on the Standard MOH Module for signal attenuation.

Music Level Adjustment

1. Set the trim POT (labeled VR1 MOH VOL) at about mid-point.

2. Access an idle CO line, and dial into the system on another CO line.

3. When the system begins to ring, press [HOLD] to place the first call on hold.

4. Answer the ringing CO line. You should hear the MOH from the previous (now holding) CO line.

5. Adjust the music level at the source. That is, use the volume control of the music source to adjust the MOH level to a desirable level.

6. If the music begins to sound distorted do not increase the source level any further. Rather, adjust the source level down slightly and use the trim POT for further adjustment.

7. If a comfortable desired music level cannot be obtained using these techniques, it is likely that the music source is not properly matched to the MOH input circuitry.

In some circumstances, there may be broadcast restrictions associated with music. Check with the original distributor and/or the radio station for copyright and broadcast restrictions concerning Background Music and Music-on-Hold.

External Music—Option Module

The Option Module may be installed for several feature upgrades. One of these upgrades is the addition of a second music source. When installed, the Option Module provides an MOH 1/8 in. phono jack (refer to Figure 2-25: 1/8 in. Phono Jack) labeled J2 MOH (located at the bottom-edge of the Option Module toward the right) that replaces the music circuit of the Standard MOH/BGM Module and an 1/8 in. phono jack labeled J4 BGM that adds a second BGM channel. J4 is located at the bottom edge of the Option Module center left.

To install the external music source:

1. Attach an 1/8 in., two-conductor, phono plug to one end of a length (5 ft. min.) of shielded cable.

2. Connect the other end of the cable to the speaker output terminals of the music source.

3. If the music source has an earphone jack, attach another 1/8 in. phono plug (or other specified connector) to the other end of the cable, and plug it into the earphone jack on the music source.

4. Plug in the AC power cord for the music source. If possible, use a separate AC outlet than the one being used for the KSU. Turn ON the AC power to the music source.

5. Insert the 1/8 in. phono plug into the appropriate music source jack inside of the KSU.

6. Since the MOH music source serves to provide MOH/BGM, it is best to adjust the input level such that MOH is at a comfortable level.

2-50 DHS Installation

To set a desirable MOH level:

1. Set the trim POT (labeled VR1 MOH VOL) at about mid-point.

2. Access an idle CO line, and dial into the system on another CO line.

3. When the system begins to ring, press [HOLD] to place the first call on hold.

4. Answer the ringing CO line. You should hear the MOH from the previous (now holding) CO line.

5. Adjust the music level at the source. That is, use the volume control of the music source to adjust the MOH level to a desirable level.

6. If the music begins to sound distorted do not increase the source level any further. Rather, adjust the source level down slightly and use the trim POT (labeled VR1 MOH VOL) for further adjustment.

7. If a comfortable music level cannot be obtained using these techniques, it is likely that the music source is not properly matched to the MOH input circuitry. You may need a 600 ohm matching transformer to properly interface the music source.

8. The BGM music level can be attenuated using the trim POT VR3 BGM VOL.

The music source must be placed 5 to 10 ft. away from the KSU, to avoid any interference.

13. Loud Bell Control

When the Option Module is installed, the system provides a dry contact closure to signal externally powered alerting devices for any incoming CO Line call. Transferred CO Lines that recall system wide will also activate the LBC, in the same cadence as for an incoming CO Line ring.

5. Terminate the other end of the cable on an industry standard 66M1-50 block for interconnection to the loud bell and power source.

6. Terminate the Loud Bell and power supply leads on an industry standard 66M1-50 block.

7. Using cross-connect (jumper) wire connect each of the three LBC components (contact, bell and power source) in series fashion.

The LBC output on the KSU provides only interrupted dry contact closure during the ringing period of incoming CO Lines.

Relay contact on DHS are rated at 24V DC 1.0 amp. Do not apply AC voltage to these contacts.

14. 2-Port Analog Adapter

The 2-Port Analog Adapter is used to connect analog SLTs and other analog devices to the system. The analog device must provide DTMF (touch tone) signals in order to make intercom calls, access outside lines and to activate system features. Some examples of analog devices are: telephone answering device (TAD), facsimile machine (FAX) or modem.

The 2-Port Analog Adapter is not an OPX device as determined by FCC Rules. Additional equipment is required to support OPX lines. The Analog Adapter will not support Message Waiting Indication for SLT devices. The Analog Adapter will supply Stutter Dial Tone to the user.

The 2-Port Analog Adapter is designed for installation at the MDF but may be positioned anywhere along the cable path between the KSU and the SLT (or other analog device).

Do not exceed the maximum cable length from KSU to SLT regardless of where the 2-Port CO Module is installed.

1. The 2-Port Analog Adapter is contained in a wall mount enclosure with pre-drilled flanges for simple mounting. Properly mounted, the hinged cover will open upward and lock into position for servicing.

2. Inside the enclosure, the 2-Port Analog Adapter Printed Circuit Board (PCB) is seen with three RJ-11 modular jacks along the bottom edge of the PCB. One oriented toward the right side of the 2-Port Analog Adapter PCB is labeled IN. The other two jacks are labeled OUT1 and OUT2.

3. Extend each of these jacks to the MDF using modular cords and terminal blocks.

4. Once on the MDF, connect the IN jack to the desired digital station port to be used for analog device interface. This connection requires that the green and red wires (White/Blue pair) be used.

5. The modular jack OUT1 is now operational as an analog device port with the same station number that would have been used by a digital key telephone connected to this port.

6. The modular jack OUT2 is also now operational as an analog device port with a station number assigned from the upper range (B2 voice channel). The number assigned is from (58-81). Determining the number is done by association; if the B1 voice channel station number connected to the 2-Port Analog Adapter is 11, then the

2-52 DHS Installation

B2 voice channel station number is 59 (the adapter’s channel station number plus the difference of 48). Use this relationship in numbering to determine the B2 channel station number, or simply dial an Executive Key Telephone from the B2 station port and read the display.

The 2-Port Analog Expander is a single PCB identical to the PCB of the 2-Port Analog Adapter. One 2-Port Analog Expansion may be housed in the 2-Port Analog Adapter enclosure. The expansion is shipped with screws used to secure it to the existing 2-Port Analog Adapter PCB stand-offs. Since the PCB and circuit function are identical to the 2Port Analog Adapter, follow the installation wiring instructions provided for the 2-Port Analog Adapter (Refer to 14. 2-Port Analog Adapter).

Installation

1. Position the 2-Port Analog Expander over the stand-off posts that are factory installed on the 2-Port Analog Adapter PCB.

2. Using the screws supplied with the 2-Port Analog Expander, secure the 2-Port Analog Expander PCB to the stand-off posts (refer to Figure 2-28).

Only one 2-Port Analog Expander can be installed in a 2-Port Analog Adapter housing.

System Check-Out 2-53

16. Headset Installation

The system supports integrated headset operation. Customers may take advantage of this standard system feature at any key telephone. Most headsets will operate without extra equipment or need for additional steps in user operation.

Installation

1. A headset adapter that uses a toggle switch to select between Headset and Handset use is desirable. The headset adapter is plugged directly into the Handset jack.

2. The telephone handset is then plugged into the headset adapter.

Non-amplified headsets receive operating voltage from the headset circuitry built into the phone (refer to the headset manufacturer's instructions for information regarding

compatibility, power source, power adapter or batteries, and special options).

On amplified headsets with self-powered (battery) headset adapters, the key telephone MUTE operation may not mute the headset. This is because the key telephone MUTE function removes system battery from the microphone at the handset jack. External power supplied to the headset will maintain its microphone voltage and allow the user to override the key telephone MUTE operation. In this case, the headset adapter MUTE function must be used (refer to the headset manufacturer's instructions for more details).

System Check-Out

After completing installation on the DHS system, it must be intitialized so that default data can be loaded. Prior to actual power up and initialization, the DHS should be checked-over to avoid startup delays or improper loading:

1. Make sure that the KSU is properly grounded.

2. Verify that all PCBs are firmly seated onto their connectors.

3. Inspect the MDF for shorted wiring and improper polarity that would affect the Digital Key Terminals or DSS consoles.

4. Make sure that the plug-ended MDF cables connected to the KSU are secure and are plugged into the correct position.

Power Up Sequence

The power up sequence involves the proper application of AC power to the system. A successful power up is assured if the installation procedure has been followed:

1. Plug the AC power cord of the KSU into the dedicated 117V AC outlet.

2. Locate the database INITIALIZATION switch SW1 on the CPU Module. It is located at the bottom edge of the CPU Module oriented in the center. It is also labeled ON and OFF.

This switch controls connection of the dynamic RAM battery circuit. When switched OFF, customer volatile database programming is not protected by the memory battery in the event power is lost. In normal operation this switch will be ON at all times.

3. To load default at this time, turn KSU power OFF.

4. Operate the INITIALIZATION (SW1) to the OFF (left) position.

5. Allow the system and switch to remain in this state for approximately two minutes.

2-54 Feature Upgrade Procedure

6. Operate the INITIALIZATION (SW1) to the ON (right) position.

7. Restore system power.

8. Observe the CPU/Power LED. After approximately 4 - 6 sec., the LED should begin to flash.

9. If the LED remains unlit or lit without flashing, repeat the above steps from Step 3.

Once the power up sequence is complete, DEFAULT DATA is loaded and the system should be fully operational.

Refer to cannot be activated.

Chapter 7, Maintenance/ Troubleshooting

Feature Upgrade Procedure

Use the following procedure to upgrade the DHS system Feature Package software. Once the upgrade is complete, the system must be initialized to assure proper operation.

Any handling of system integrated circuits must be done in a static controlled environmen t. Please use satisfactory static preventive practices while handling system components and while working on the system KSU with cover removed. (USE A STATIC WRIST STRAP!)

1. Disconnect system power and remove the KSU cover by removing each of the 4 front cover screws located at each corner.

2. If an Option Module is installed it must temporarily be removed to gain access to the system software EPROM socket (U9).

3. Use the diagram (refer to Figure 2-29: DHS Components) and locate the system software EPROM socket U9. Observe the orientation of the notch at one end of the EPROM so that the new EPROM is installed with the same orientation.

4. Using an IC extractor tool, remove the DHS software EPROM from the U9 socket.

5. Carefully remove the new software EPROM from its packing material and inspect for damage (if any damage is noticeable please contact Vodavi Customer Service).

DHS-E Description

System Technology

Incorporating state-of-the-art digital technology for voice switching and call processing, the DHS-E utilizes Pulse Code Modulation and Time Division Multiplexing (PCM/TDM). The DHS-E family is engineered to allow migration of digital telephones and accessories throughout the entire product line (refer to Digital Key Telephones, in Chapter 2, DHS

Description and Installation). ISDN-like, 2B+D technology complements the system

architecture and capabilities. On one industry standard twisted pair, key telephones perform all system functions and voice communications. Some additional features of the

DHS-E include:



A non-blocking switch, with no loss or degradation of voice signals.



Stored-Program Control (SPC), that utilizes a 16-bit, 10 MHz microprocessor.



Memory consists of 512 KB of ROM (Read-Only Memory) and 256 KB of RAM (Random Access Memory).

When an analog device interface is required, a 2-Port Analog adapter may be connected to any one digital station port. The 2B+D technology allows the DHS-E to split one digital key telephone port voice channel (B1) and the second voice channel (B2) to provide two independent Single Line Telephone (SLT)-type device interfaces.

The 2-Port Analog Adapter may be expanded with the 2-Port Analog Expansion (in the 2Port Analog Adapter housing).

The 2-Port Analog Adapter and 2-Port Analog Expansion each require one dedicated digital station port.

KSU Components

The DHS-E platform is comprised of three key telephone models and a modular Key Service Unit (KSU) which houses the following KSU components:

DHS-E system.

3-2 DHS-E Description

DHS-E is expandable to meet a variety of applications. Regardless of the configuration,

the system has sufficient resources to allow completely non-blocked access to all facilities (intercom and CO lines).

An external music source may be connected to each BGM/MOH Jacks via a 1/8 in. phono plug for BGM/MOH listening. All system features are supported by the equipment provided in the DHS-E KSU. The Main Processor Board provides two Dual Tone MultiFrequency (DTMF) receivers and two Tone Detectors specifically for ECF, DISA, Unsupervised CO Line Conference, and Dial Tone Detection.

Connectors for SMDR and PC Programming are standard 9-pin RS-232 (serial) connectors. Connectors for Loud Bell Control, External Voice Paging, MOH and BGM are 1/8" phonotype connectors.

SLT operations do NOT use System DTMF and Tone Detection resources.

System Administration

The system's default customer data base can be entered and changed, under password control, from any Executive Key Telephone. All Customer information is protected by an internal rechargeable NiCad or NiMh battery. Programmable password protection is allowed for each station, system administrator and external (DISA) callers. An optional PC Programming Software is available to program the DHS-E Systems. This Software allows the user to program OFF/LINE and then the programmed data can be uploaded to the system.

Key Service Unit

The DHS-E KSU is a modular wall mount design. It is a self-contained cabinet with internal power supply, common control circuits (CPU board) and two 3 x 8 Modules (refer to

Figure 3-1). The power supply AC transformer is hard-wire selected for either 117 V AC

10%). The KSU is designed for wall mount and shipped with a wall mounting template and hardware. The compact KSU weighs 26 lb. and is UL compliant. A KSU opening at the bottom of the KSU accommodates cable entry requirements through the outer housing for connection to the MDF.

Figure 3-1: DHS-E KSU

3-4 DHS-E Description

Power Supply

The power supply circuitry of the DHS-E incorporates a linear design transformer with a choice of input voltage taps. The transformer primary windings are shipped wired for 117V AC applications. Since the power supply is linear in design the output voltage varies between 21.6V DC and 32V DC depending on load and stability of the input voltage. The output voltage is delivered to the CPU board for distribution and rectified there for logic and control voltages.

Two fuses are equipped on the power supply board, one for AC input over-voltage protection and one for DC output over-voltage protection. A DPDT (Double Pole Double Throw) switch is accessible from outside of the KSU when the KSU cover is in place. The DPDT switch will simultaneously switch AC input and DC output circuits ON and OFF. In the event battery backup operation is desired and equipped via the optional Battery Charging Unit (BCU), the KSU switch may be used to switch OFF/ON power from both sources.

The power supply wiring harness is equipped with a Mate-n-lock connector on the DC output for connection to the BCU. When equipped, the BCU will maintain complete system operation during commercial power outages. A current draw/configuration chart is included in this document (refer to Table 3-11: Battery Sizing Chart ).

Central Processor Unit (CPU)

The CPU board is standard in the Basic KSU. This board contains all circuitry required to control the fully equipped DHS-E . Six bus connectors are provided where the station/CO line interface 3 x 8 Module is connected. All digital voice switching and call processing data switching is accomplished on the CPU board. The CPU board also contains a 2400 baud modem for remote programming.

Modem

The built-in 2400 baud modem will work with DISA lines or transferred lines. It will not operate with Direct Ringing CO lines. Set the “RMT X_RATE” to 2400 baud.

3 x 8 Module

The 3 x 8 module provides interface of three loop-start CO lines and eight DHS-E key telephones.

Each CO line circuit incorporates over-voltage protection, ring detector, loop detector, loop/pulse-dial relay, current sink circuit, coupling/isolation transformer (impedance 600 ohms), hybrid circuit and combo (CODEC & filter) polarity guard circuit and radio frequency noise filter.

Each digital key telephone port is comprised of a proprietary transceiver designed using ISDN type 2B+D architecture.

Physical connection of stations and CO lines to the 3 x 8 module is made through one male 25-pair amphenol-type connector to the MDF (Main Distribution Frame). Station power and signaling to the digital key telephones are provided via a single twisted pair from the 3 x 8 module.

When installing a 3 x 8 Module in location CN4, the Extender Ribbon Cable that was supplied with the KSU must be utilized. Do not lose this cable; it is irreplacable.

DHS-E Description 3-5

Although all existing 3 x 8 boards can be used when upgrading an existing DHS system, some pre-qualification must be performed. This pre-qualification will prevent noise problems on stations that can result from a firmware incompatibility issue. This issue can be corrected by obtaining the correct firmware from Vodavi (refer to

DHS-E Installation 3-15

General Site Considerations

The first step of DHS-E installation is to locate an acceptable site for the common equipment (KSUs, boards, etc.). When locating a mounting site for the KSUs, the following points must be considered:



KSUs are designed for wall mounting and should not be mounted directly to a masonry or plasterboard wall. It is recommended that a 1/2 in. plywood backboard be firmly mounted to the wall, and the KSU and MDF be mounted to the backboard.



The location must have access to a dedicated 110 V AC (±10%), 60 Hz, single-phase circuit with a circuit breaker or fuse rated at 15 amps. A 3-wire parallel blade grounded outlet should be within approximately 6 feet of the lower left rear of the KSU mounting.



The location must have access to a good earth ground, such as a metallic cold water pipe without non-metallic joints. The ground source should be located as close as possible to the system.



The system should be located in an area that is well ventilated with a recommended temperature range of 68-78° F and a relative humidity range of 5-60% (noncondensing).



Protection from flooding, flammable materials, excessive dust and vibration.



The site should be away from radio transmitting equipment, arc-welding devices, copying machines and other electrical equipment capable of generating electrical interferences.



Operation of this equipment in a residential area is likely to cause interference. In which case the user, at his own expense, is required to take any necessary measures to correct the interference.

Necessary Tools and Supplies

To make installation easier, consult the following pages when preparing to install the system.

Tools

The following tools are recommended to install your DHS-E system. Others may be needed for certain troubleshooting procedures.



Use shielded cable if RFI/EFI is expected.

3-16 DHS-E Installation



Six conductor modular jack assemblies for all station instruments (recommended).



Standard punch-down terminal block(s), 66M1-50 type, as required.



Industry-standard, 25-pair cable(s) with a 50-pin male amphenol/AMP type connector for connection from each equipped 3 x 8 module to the MDF.

4. KSU Installation

1. Using the mounting template as a guide, mark the 2 mounting screws locations on the MDF backboard.

2. Pre-drill 2 screw holes and install 2 pan-head No. 10 screws into the backboard. The screw heads should protrude about 1/4-in. from the backboard plywood surface.

3. Lift the KSU over the 2 screws allowing the screws to extend into the KSU slotted mounting holes. As the KSU is allowed to rest in place on the mounting screws it will slip over the screw shanks until the top of the slot is reached. Properly installed, the KSU power transformer (where the KSU AC power cord is located) is positioned in the upper left corner. The power switch and Power/Heartbeat LED are positioned at the left side of the KSU toward the bottom.

It is very important that the KSU be correctly mounted to allow proper power supply heat dissipation.
