circuitry housed on printed-wire-boards that simply slide in and out of the cabinets. Installing the DXP is quick and easy, and the variety of boards makes the system versatile enough to meet virtually any business’s needs. The DXP is comprised of two cabinets, the main cabinet and the expansion cabinet.

The DXP’s Modular Design

One of the benefits of the DXP is its flexibility, and that flexibility comes from its modular design.

The term “Modular design” means that the system’s electronic components are housed in a series of self-contained printed wire boards that can be arranged quickly and easily into a variety of configurations.

By changing the printed wire boards, you can find the right combination of features and telephone capacities to suit the needs of your particular client.

For example, if a client desires maximum line capacity, you can

configure a fully-equipped DXP main cabinet and expansion cabinet for a total of 120 lines on 16 telephones. If a client wants maximum

telephone capacity, you can configure the system to provide 32 lines

on 192 telephones.

The number and type of boards that you install determines the DXP’s

line and telephone capacities. You can also update the DXP’s software card to enhance the features and capabilities of the DXP.

The DXP allows you to make many of these modifications without disrupting the client’s normal telephone service.

Introducing

The DXP Main

Cabinet

The main cabinet (DXCBM) contains the main power supply and up to 12 printed-wire-boards. The cabinet is 26 inches wide, 19 inches high, and twelve inches deep, and it’s comprised of the following

components:

l an external, ventilated sheet-metal housing with detachable

front cover,

l the card cage-the metal frame into which you insert the

printedwire-boards,

and the backplane-a large printed-wire-board that provides

the circuitry to connect the individual boards together.

When you first open the main cabinet, you will see an empty space where the power supply is to be mounted. The power supply provides DC operating power for the DXP printed-wire boards and also for the individual digital stations as well. The power supply is shipped separately, and we’ll cover it later in this manual.

The space directly above the power supply is reserved for the ring generator. Industry-standard telephones require voltage to enable ringing and to turn on the message-waiting lights; the ring generator supplies the required voltage to all of the IST stations on the DXP. You must have a ring generator if you are going to use IST stations, and you must have a ring generator in each cabinet that supports IST stations. It’s a good idea, therefore, to plan on configuring all of your IST stations through one of the cabinets.

Moving from left to right in the main cabinet, the slots for boards are as follows:

Using The DXP

Modem

The space directly below the interface board (slot one) is reserved for the DXP modem, DXMDM. The modem allows you to service and program the DXP from a remote location. The modem runs at a maximum of 2400 baud, and it receives its power from the power supply. Please note that this is a proprietary modem. For more information on the modem, see

IMI89-139.

Using The

Battery Backup

You can install a battery backup (BBLDX) that provides a minimum of one hour of operation should the DXP lose power. The DXP supports a maximum of two battery backups. If you are using an expansion cabinet, you need two battery backups to guarantee at least an hour of backup operation. You can, however, use two battery backups without an expansion cabinet in order to provide even longer backup time. For more information on using the battery backup, see

IMI89-074.

Interface Boards

The first slot in the cabinet, moving from left to right, is for the Interface 1 board sent from the main cabinet to the expansion cabinet; it makes sure there is no integrity loss in the digital signal between the two cabinets. So, you’ll only need an interface board if you’re going to use an expansion cabinet (for information on the expansion cabinet’s interface board, see section 1.9, Introducing The Expansion Cabinet). The slot for the interface 1 board is smaller than any of the other card-cage slots. The interface board is the only half-sized board that inserts directly into the backplane. Both interface boards, the one for

the main cabinet and the one for the expansion cabinet, are shipped

with the expansion cabinet. For more information on the interface boards, see

Services Board

The second slot is reserved for the Services board (DXSRV). The services board houses all of the following: the master timing and synchronization circuits for voice and data paths, the conferencing circuitry (the DXP has twenty-six time slots dedicated for

conferencing) the digital pad for controlling audio on a per-channel basis, and the voice and data time switches. The services board also provides a 6-pin modular jack that serves as an input for

music-on-hold and background music as well as an output for an

external paging amplifier. The status light on the front of the board

stays on-steady to indicate normal system operation. The light goes off or flashes to indicate system malfunction. For more information on

the Services board, see

IMI66-085.

CPU Board Assembly

The central processing unit, or CPU, board belongs in the third slot

(DXCPU-68K). The CPU board is actually an assembly containing the

main board and two additional cards. The CPU board holds the primary processing and control circuits for the DXP system; it also contains the master processor, the interface connector for the system memory, two The CPU board has four 6-pin modular jacks that provide the interface for two serial data devices and four relay contacts. Just as with the

services board, the status light is on-steady to indicate normal system

operation. The CPU light, however, flashes to indicate system malfunction and is steady-off to indicate a loss of power.

Along with the printed-wire-boards that slide into the backplane, the DXP has smaller circuit cards that mount directly onto certain full-sized boards. We don’t use the terms “card” and “board” interchangeably; boards mount directly into the DXP, while cards mount onto boards. Two of these additional cards, the RAM and

Software cards, mount onto the CPU board and make up the assembly.

The Station

Boards

Station boards provide the interface for connecting the cables from telephone stations to the DXP. You can use a station board in Universal slots 1 through 5 in the main cabinet and universal slots 6 through 11 in the expansion cabinet. The DXP accepts digital, analog, and industry standard telephones. In order to use these different types of stations, you must install the correct station board. The following list explains each station board.

The stations are labeled on the front of the cabinet; note that the station designations go from the left to the right.

For more information on the Station boards, see

Analog Station Board

The analog station board provides support for Comdial’s proprietary

analog telephones (such as the various board supports either 8 or 16 stations and uses either one or two 25-pair

The Line Boards

Line boards provide the interface for connecting the central office, or

CO, lines to the DXP. You can use a station board in Universal slots 1

through 5 in the main cabinet, universal slots 6 through 11 in the expansion cabinet, and line slots 1 through 4 in the main cabinet (you can only install a Tl board in the second line slot or the fifth universal

slot of the main cabinet, or in universal slot 8 or 12 in the expansion cabinet). While line boards are optional, it’s rare that you will have an

application that won’t require CO lines. The DXP supports several different types of line boards,

l Loop start, l Multipurpose, l Direct Inward Dialing, or DID, l and

Tl.

Make sure that the lines coming from the CO match the line boards that you install in the DXP. Having a Tl board does not mean you have Tl lines, for example. Be sure to coordinate with your CO before you plan your line configurations. Special software may be required to

support certain line boards. Your class instructor will give you further

details on software requirements when you take the classroom portion of the training.

Like the station boards, each line board has a pre-power jack that

allows a technician to service the board while the DXP still has AC

power. The status light on each line board indicates when a line is in use: off

with a five-second blink rate on indicates that all lines are idle; on with a five-second blink rate off indicates at least one busy line. A rapid flash indicates a malfunctioning microprocessor on the line board. All line boards provide secondary surge protection; Chapter Three discusses secondary and primary surge protection.

Introducing The DXP 1 - 11

DXP Correspondence Manual

Line Boards-Loop-start Line Board

The loop-start line board (DXPCO-LP8, LP4) supports loop start lines, and it is available in either a four- or eight-port capacity. Each

loop-start line board has modular jacks that provide connections for either four or eight lines. You can connect an industry-standard telephone to the bottom jack to serve as a power-failure telephone. If the DXP should lose power, the power-fail telephone will continue to operate. The LED on the front of the board indicates when a line is in use: off with a five-second blink rate on indicates that all lines are idle; on with a five-second blink rate off indicates at least one busy line. A rapid flash indicates a malfunctioning microprocessor on the line board. Each loop-start board also has a power fail and auxiliary interface. For more information on the loop start board, see

IMI66-085.

Line Boards-Multipurpose Line Board

The multipurpose line board lines, ground start lines, or E and M tie lines. Like the loop start board, the multipurpose board also is available in either a four- or eight-port capacity, and you can use any combination of the three line types. However, ports three and four on each multipurpose board are the only ports that support E and M tie lines. The LED on the front of the multipurpose board functions exactly like that on the loop start board; each multipurpose board also has a power fail and auxiliary interface.

Line Boards-T1 Board

The Tl board

(DXPTl)

provides 8, 16, or 24 channels of voice

transmissions over a single four-wire cable using multiplexing

techniques. You can install a maximum of four Tl boards, two in each

cabinet, but you can only install a Tl board in the second line slot or the fifth universal slot of the main cabinet, or in universal slot 8 or 12 in the expansion cabinet. You can configure the Tl board with a combination of loopstart, ground start, DID, and E & M Tie lines. When you take the DXP classroom training, you’ll get a more in-depth overview of the Tl board. For more information on the board, see

IMI89-141.

Line Boards-DID Board

The DID board (DXPCO-DD8, DD4) lets, stations have their own telephone number without having a separate line dedicated to that

station. The basic idea of DID is this: the central office sends digits to

the DXP, which interprets the digits and routes the call to the appropriate station. For example, you can have fifty stations and only

ten DID lines, and each station can still have its own published telephone number. However, only ten of the stations can be on calls at one time. DID lines are incoming only, so if you need outward dialing, you’ll need more than just DID lines. Like Tl , DID will be covered more deeply in the classroom portion of this training. For more information on the DID board, see

IMI89-103.

Using The

Auxiliary Board

and Add-On

Cards

The auxiliary board is an all-purpose “mother board” that

accommodates up to four smaller option cards. You can install two

auxiliary boards in the DXP, but you can only install them in the Universal / Auxiliary slots of the main cabinet. The option include the DTMF Tone card, DXOPT-TON, the communications card, DXOPT-COM, and the Tl sync. card, DXOPT-SYN. These cards mount onto the auxiliary board, much like the RAM and software cards mount onto the CPU board.

While you can install a station, line, conference, or auxiliary board into either universal / auxiliary slot (first two slots next to the CPU board), we recommend that you try to leave at least one of these slots for an auxiliary board, even if you don’t need an auxiliary board now, you may want to expand the system later. Remember, these are the only two slots in the entire system that will accept an auxiliary board. Use the line slots and universal slots for line and station boards before you use a universal / auxiliary slot.

car&

DTMF Tone Card

The DTMF tone card expands the capability: without a tone card, only two industry-standard telephones can dial out of the DXP simultaneously. Each DXOPT-TON card provides four more IST dialing paths. So if you are going to have several IST telephones, it’s a good idea to install a tone card to make

sure that more than two of them can dial-out simultaneously. You can

install four tone cards on each auxiliary board (see Installation Instructions, for more information).

Communications Card

The auxiliary board also supports the communications card

(DXOPT-COM);

the DXP has two serial data ports on the CPU

board. Each communications card provides four additional serial data ports; you may need these ports for additional PC Attendants or

printers, for example. Keep in mind that the two serial ports on the

CPU board are the only two true-high-speed ports. Depending upon system traffic, the serial ports on the

comm.

card may not operate at a

true 9600 baud rate. You can install up to two corn-cards on each

auxiliary board, but you must install them on the bottom two slots of the auxiliary board. For more information on the Corn. card, see

IMI89-124.

Synchronization Card

Finally, the DXOPT-SYN, or sync. card, adjusts the DXP Tl transmit frequency to match the frequency received from the central office or master DXP. You only need a sync. card if you are using the Tl board, and you can only install one sync. card into the DXP. If your

board is connected to the C.O., you must have a sync. card. If you

have two

DXPs

connected together with the Tl configured as E & M

tie lines, only one DXP must have a sync. card. For more information

The Expansion

Cabinet

The expansion cabinet is very similar in design and function to the main cabinet. The main cabinet holds 12 boards, and the expansion cabinet holds up to eight additional boards. As its name indicates, the expansion cabinet simply increases the number of stations and lines that you can have on the DXP system.

The far left of the cabinet houses the expansion-cabinet power supply; this power supply is designed specifically for the expansion cabinet. Chapter three discusses the power supply in more detail. The

backplane and card cage are very similar to those in the main cabinet.

This first slot holds the interface 2 board. The interface 2 board connects to the interface 1 board to secure the integrity of the digital

signals between the two cabinets. You must have an interface 2 board if you are going to use an expansion cabinet. The remaining slots in the expansion cabinet, universal slots 6 - 12, each can hold either a line, conference, or station board. You cannot use an auxiliary board

in the expansion cabinet. For more information on the expansion

cabinet, see

Concluding

Chapter One

The DXP is comprised of a series of mandatory and optional printed-wire boards: the power supply, CPU and Services boards are mandatory for system operation, as are the Software and RAM cards. The line boards, station boards, auxiliary boards, and conference

boards are optional depending upon your application. Before you go any further in this series complete the study at the end

of this chapter. By now, you should have a general understanding of the function and capabilities of the DXP hardware, printed-wire boards, and expansion cabinet; if you aren’t secure in your knowledge of any of these, rewind Tape One and watch it again; then reread Chapter One.

Planning An Installation

2.1

Introducing

Chapter Two

One of your primary responsibilities as the DXP installer is to determine the type and quantity of equipment needed for each

installation site. Remember that the needs and specifications of each installation site will be different based on the number of lines, stations and peripheral equipment that fits that customer’s business. When you begin a new installation, ask yourself some of the following questions:

l What are the client’s present and future telecommunications

needs? Are you replacing an existing business telephone system,

or is this a completely new installation?

l What are the problems the client is experiencing with his or her

old telephone system? Why is a DXP the right telephone system?

l How many lines and stations are you going to use? Remember to

leave plenty of room for future expansion.

l Will you use ground start, loop start, l Will you have digital, analog, or IST stations?

l What peripheral equipment will you use: paging device, music

source, or battery backup, for example.

Tl,

or DID lines?

You’ll have to answer all of these questions well in advance of actually ordering any of the equipment for you installation. Keep in

mind that your customers aren’t going to know whether they need

DID or ground start lines, for example, so you will have to make those

decisions based on your understanding of the client’s needs.

Planning An Installation 2 -

Page 36

2.2

ordering

The Right

Equipment

In determining what equipment to order, keep the client’s long-range plans in mind. Make sure that you can add lines or stations when the time comes to do so.

Remember that the two auxiliary/universal slots are the only slots that

accommodate Auxiliary boards. If you install a line or station board in these slots, there will be no room for Auxiliary boards when the client needs them. If at all possible, reserve at least one of the auxiliary/universal slots for an Auxiliary board, and put the station and line boards in the universal and line slots respectively.

For assistance in choosing the right boards, consult Comdial publication

DXP Software Request Form. Both of these publications are in the DXP System Manual. You can find the product codes for DXP parts on the last page of

You may also want to purchase another Comdial videotape series entitled “How to Sell Business Telephone Systems (V-l OC), ” which provides not only marketing and programming tips but also gives practical examples of the types of questions to ask a client.

Evaluating

The

Installation Site

An important part of your pre-installation work is to map-out the

geography of the site. If you can, get up-to-date blueprints of the building. If blueprints are unavailable, draw up your own rough floor plans and cross sections of the building.

Make sure that at a minimum you have all of the following

information:

l The location of the equipment room. l The anticipated location of all of the various telephones.

l The current location of the cable runs for pre-existing CO lines

and phone sets.

Planning The

Dedicated

Equipment

Room

Comdial recommends that you use a dedicated equipment room for the DXP installation. If you do have other equipment in the room, make sure you check for radio frequency interference. If you aren’t going to use an equipment room, make sure to install the DXP in a low-traffic area where the equipment and wiring won’t be bumped or knocked loose.

Keep in mind that the distance between the main cabinet and the

stays between 32 and 122 degrees fahrenheit with less than 90 percent non-condensing humidity.

An important element to the equipment room is the AC power; hopefully, your equipment room has accessible outlets, if not, make sure to have a professional electrician install one. The DXP requires a dedicated

Before you begin your system layout, you need to make sure that you have all the right tools for a proper installation. Most of you have installed telephone systems before, so none of this information is new to you. In truth, you’ll probably have a standard list much longer than the one we provide. Use these items as an essentials list, a bare minimum of what you should have to install a system. You’ll need the following:

l fasteners, either wood screws or toggle bolts, to attach the

common equipment to the backboard,

a screwdriver to match the wood screws,

an electric drill,

l punch-down tool for fastening wires to a type-66 block, l crimping tool for 623-type modular plugs, l 3-prong AC circuit tester,

10 or 12 gauge insulated, solid-copper wire for grounding the

system,

all associated surge protection-AC, line, and serial,

l a connectorized female 25-pair cable (at least ten feet long) for

each station and line board (note that loop-start line boards use modular jacks for line connections)

This list is a minimum of what you’ll need. Your own experience will guide you in selecting what is necessary.

line blocks,

the music source,

Even if you are not installing these devices, allocate space for them on the MDF because they may be installed later.

As far as the location of the DXP on the board, you will want to put it in the left-hand comer since all of the wiring comes out on the right

side of the cabinet. If you are going to mount the battery backup on

the left, be sure to leave adequate room. Whether you are using an expansion cabinet or not, you should leave enough room on the MDF for both cabinets. The expansion cabinet always mounts above the main cabinet. The cabinets have to be no more than two inches apart to allow the cables from the interface boards to connect.

Make sure all of your cable runs are as short as possible. When you

wire your stations, remember that the length from the DXP to the

stations depends upon the type of station and the gauge of wire (see

section 1.8 in this manual for more information). You also want to

keep the wires as far away from fluorescent lighting as possible. If you

do have to cross these lights, run the wires perpendicular to the lights

in order to keep interference negligible.

Checking The

Hardware

It’s a good idea to check all of your hardware thoroughly before you get to your installation site. Unpack all of the equipment and make sure that there has been no damage during shipping; then test each

piece individually to make sure it operates correctly. Use the .

following list as a general guideline for pre-installation testing.

Check the power supply voltages of both the main cabinet and expansion cabinet’s power supply. Refer to correct power supply voltages.

Once you know that the power supply voltages are correct, slide the power supply into its location and plug it in. You can now begin installing and testing your boards. All of the boards are shipped in static-safe bags. Make sure you are in a static-safe area and wearing a static-discharge wrist strap before you handle any of the boards or cards.

Visually inspect each board when you take it out of the box to make sure there are no visible defects and to make sure you

have the correct board.

IMI66-085

for the

Begin testing with the CPU and Services board (the RAM and software cards must be installed). When testing the CPU board, make sure that DIP switch 8 is in the “on” position. With both boards inserted and seated properly, turn on the power supply and watch the LED on each board: Remember that many of the boards have a different LED flash rate to indicate proper operation.

Read Section One of this manual for LED light indications. It’s a good idea to test all of the boards in the actual slots where they will be installed, if for no other reason than to make sure you have planned the configuration accurately. By testing all of the boards, you also make sure that each of the is fully functional.

If you do have a board malfunction, turn the power back off and re-seat the board; if you didn’t insert the mounting screws, do so. Power the system back up and check the boards again. If

you still have a malfunction, try inserting a different CPU or

services board; if the other board works, you know there is a

problem with your original board. Should you experience any of these malfunctions, contact your Comdial technical-services representative for more troubleshooting tips and technical support.

Always remember to turn the power off before you insert the

next board to prevent damaging the boards. Some of the

boards, the station and line boards specifically, have pre-power

jacks that allow you to work with the power on. Other boards,

like the AUX. board, require that you have the power off

before doing any work. It’s a good idea to turn the power off

just in case.

Chapter Two

With your station boards installed, do a quick check on the digital stations themselves. Plug each station into a station port and then use a digital armiger (you can purchase these from any supply house). Plug the

armiger

telephone that you know is operable. Then unpack each of the

telephones and test them on one of the station ports. Testing the boards one-by-one this way not only guarantees that all of our equipment works as it should, but it also makes it immediately obvious which board is the problem should a malfunction arise. Plus, you’ll know all of this information well in advance of your installation date.

This section of the training series has given you a foundation for planning and evaluating your installation site. If you are unsure about

any of this information, rewind tape two, Planning an Installation, and
