Installing Telephones and

Adjuncts

The control unit supports the MLX-5, MLX-5D, MLX-10, MLX-10D, MLX-10DP,

3

MLX-16DP, MLX-20L, and MLX-28D telephones, with or without Direct Station

Selectors (DSSs), as well as analog multiline and single-line telephones. It also supports various adjuncts which may require Multi-Function Modules (MFMs) or other adapters for installation.

This chapter provides installation instructions for the following procedures:

Installing Multi-Function Modules

The Multi-Function Module (MFM) is an optional adapter that provides a modular jack connection to MLX telephones for the two classes of adjuncts listed below:

MERLIN LEGEND Communications System Release 5.0

Installation 555-650-140



Issue 1

June 1997

Page 3-2

■

■

Tip/ring (T/R) devices such as single-line telephones, fax machines, modems, and credit card verification terminals. Once connected, the

MLX telephone and adjunct work independently of each other. This means they can send and receive calls at the same time. The MFM is the only T/R adapter you can use with MLX telephones.

Supplemental alerts such as bells, chimes, horns, and strobes. These alerts notify people in noisy areas of incoming calls.

Considerations

Review the following items before you begin the procedure.

■

If you install an MFM, do so before you assemble the MLX telephone.

■

■

■

■

■

You must connect the KS 22911 power supply to an electrical outlet within 50 ft. (15 m) of cord length of the MLX telephone.

If you connect an MFM and two DSSs to a telephone, you must install a

406743419 power unit.

If a wall jack is more than 7 ft. (213 cm) from an MLX telephone, you must use a longer D8W cord.

The MFM uses one of the two channels when it is active. This means that when an adjunct, such as a fax machine, and the MLX telephone are in use at the same time, Voice Announce to Busy is not possible. (Voice

Announce to Busy is a feature that allows users to be paged on the speakerphone even if they are on a call.)

The MFM has two jumper blocks that are factory-set for T/R operation.

The MFM is packaged with the following items, shown in

Figure 3-1 :

— KS22911 power supply

— 400B or 400B2 adapter

Insert the other end of the adjunct cord directly into the port for the logical ID on the 012 or 016 module as indicated on the system form. Go to Step 7.

Test the adjunct by dialing its associated extension.

General Purpose Adapter

A General Purpose Adapter (GPA) lets you connect a T/R device—such as a single-line telephone or modem—to an analog multiline telephone. The device must be touch-tone, not rotary.

NOTE:

The GPA is intended for answer-only service, unless the telephone has direct access to a line. It does not have touch-tone receivers or pulse dial detectors; therefore, the associated analog multiline telephone must dial calls.

The GPA cannot be used with a MERLIN II System Display Console.

When the system forms indicate a GPA for installation of an adjunct, follow the steps below.

Plug one end of a 4-pair adjunct D8AC cord into the VT jack on the back of the GPA.

Plug the other end into the OTHER jack on the underside of the analog multiline telephone.

■

Basic. This setting is used to dial and answer calls from an analog multiline telephone or to attach a T/R adjunct such as a single-line telephone or answering machine. Incoming calls ring only on the analog multiline telephone. This setting also allows the user to originate and receive calls on the telephone while using a computer with a modem attached to the GPA. However, if this setting is used, data calls cannot be answered automatically.

Join. This setting is used to add a recording device or a single-line telephone to a call that is in progress on the telephone. You cannot originate or answer calls on this setting.

Automatic. Use this setting when a GPA connects a modem to an analog multiline telephone for answering calls or answering machine.

Headsets

Headsets are designed for hands-free telephone use and consist of several components, depending upon whether manual or one-touch operation is used.

Any Lucent Technologies headpiece works in either mode.

Headpieces

Six different headpieces are available. Each is light, comfortable, and uses a transparent voice tube to eliminate a cumbersome large microphone. Each comes with a 10-ft. (305-cm) coiled cord and a quick-disconnect latch.

■

Mirage  . This is a small, almost unnoticeable, monaural headset that uses a disk-shaped receiver. It can be worn on either ear, instead of a headband or ear tip. This headset is not useful in noisy environments.

■

Supra Binaural. Sound in both ears with soft ear cushion and adjustable headband.

Supra Binaural Noise-Canceling (NC). Same as above with noise-canceling microphone on flexible boom features windscreen and reduces background noise transmission by up to 75 percent.

Manual Operation (Analog Multiline

Telephones Only)

Manual operation is appropriate when a headset is used occasionally. You pick up the handset to answer a call and replace it to hang up. The headset consists of the headpiece and a modular base unit. The headpiece plugs into the modular base unit, and the modular base unit connects to the telephone through the HANDSET jack on the side of the telephone. The telephone handset is plugged into the modular base unit. The modular base unit allows you to adjust the incoming volume, switch between the headset and handset as

needed, and temporarily mute the line. (See Figure 3-21 .)

One-Touch Operation (All Telephones)

One-touch operation allows you to touch a button to answer a call. On analog multiline telephones, use a headpiece with a plug prong base unit and an adapter (502C). The headpiece connects to the plug prong base unit, which in turn connects to the adapter. The adapter plugs into the OTHER jack on the underside of the telephone. The plug prong unit provides switchhook control for answering calls by pressing a button. You can also adjust the incoming volume.

On MLX telephones, the headpiece is attached to a modular base unit, which is

Loudspeaker Paging Systems

Use a loudspeaker paging system to page co-workers and make announcements. You connect the paging system to the jack of an LS or GS line/trunk that is programmed for paging.

Figures 3–22, 3–23, and 3–24 show various configurations for single-zone paging. Figures 3–25 and 3–26, later in this chapter, show single-zone and

Magic on Hold audio source. Bidirectional paging, also called talk-back, is shown in

Figure 3-26

.

Dual-Tone Multifrequency (DTMF) Signaling

You can connect external paging systems that use dual-tone multifrequency

(DTMF) signaling, such as PagePac  Plus with Zone Expansion Unit paging systems, to an LS or GS line/trunk jack programmed for paging operation, including bidirectional paging operation (talk-back). PagePac Plus does not require an adapter.

Zone paging systems, such as the PagePac series, require one LS or GS jack.

You can use any zone once the paging jack is activated.

You must use a Universal Paging Access Module (UPAM), or PagePal (for

PagePac series systems other than PagePac Plus) to connect a paging system that requires contact closure, an impedance-matching transformer, or both.

Use a Loop Start Trunk Adapter when a customer-supplied paging system does not require contact closure.

When a modem is connected to the TEL/OTHER jack on the MLX telephone equipped with an MFM, data calls can be made from the modem independently of the MLX telephone. Users dial data calls from the data terminal keyboard.

See

Chapter 6, ‘‘Connecting Data Equipment’’ , for complete information on

connecting data equipment.

Music On Hold

®

and Magic on Hold

You can connect a Music On Hold device to an LS or GS line/trunk jack programmed for Music On Hold. The system supports one such connection, either Magic on Hold or a customer-owned music source. The external music coupler (PEC 61398) uses an 8-ohm music source and two attenuation controls for setting the music level.

NOTE:

PagePac Plus equipment can be used with a loudspeaker system to provide music. Or it can provide paging without a music coupler.

If the equipment uses rebroadcasted music or other copyrighted materials, the customer is required to obtain a copyright release and may also require a copyright license from, and pay license fees to, a third party, such as the American Society of Composers, Artists, and Producers

(ASCAP), or Broadcast Music Incorporated (BMI). To bypass the release and license requirement, the customer can purchase a Magic on Hold system from Lucent Technologies, which does not require such a license.

Figures 3–25 and 3–26 show different background music configurations with single-zone and multizone paging.

Installing Direct Station Selectors

Issue 1

June 1997

Page 3-43

The Direct Station Selector (DSS) is an optional piece of telephone equipment.

You can connect up to two DSSs to an MLX-28D or MLX-20L telephone that is programmed as an operator console.

Considerations

Review the following items before you begin the installation procedure.

■

Connect the DSSs before you assemble the MLX telephones.

■

Auxiliary power is required under the following circumstances:

— An MLX telephone with an MFM and two DSSs requires a

406743419 power unit.

■

■

■

— An MLX telephone without an MFM, but with two DSSs, requires a

406943837 power unit, 400B adapter, and the D6AP cord provided with the MFM.

— An MLX telephone with one DSS and an MFM requires a

406943837 power unit, 400B adapter, and the D6AP cord provided with the MFM.

— If one carrier has three or more MLX telephones, each with a DSS attached, use a 406943837 power unit, 400B adapter, and D6AP cord for each MLX telephone and DSS after the first two.

The total length of cords between the KS22911-L2 or 406743419 power supply and the MLX telephone must not be more than

50 ft. (15 m).

Do not replace the 2-ft. (61-cm) D8AC cord (packaged with the DSS) with a longer cord. Improper operation may result.

Connect each KS22911-L2 power supply to an AC outlet that is not controlled by a wall switch.

Installing Cordless or

Cordless/Wireless Telephones

The sections below describe the ways you can connect MDC 9000 cordless or

MDW 9000 cordless and wireless telephones to the system.

MDC 9000 Cordless Telephone

You can connect the base unit of the MDC 9000 to an analog extension jack.

MDW 9000 Cordless/Wireless Telephones

The following is a brief overview of procedures and considerations for installation of the MDW 9000 telephone. For more detailed information, see the installation guide that comes with the telephone .

■

If possible, place the radio module of a wireless telephone in the same room and on the same wall as the MERLIN LEGEND Communications

System control unit.

A minimum distance of 3 ft. is required between the radio base and the control unit. The radio module must be within 24 ft. of a properly grounded 3-prong AC outlet that is not controlled by a wall switch and connects to the control unit through an analog multiline jack with a line connector.




Connecting Telephones to the Control Unit

Issue 1

June 1997

Page 3-58

■

■

■

The charging base station requires only a three-prong AC outlet that is not connected to a wall switch.

The telephone handset must be within range of the radio base. The indoor range is 400 through 600 ft. and the outdoor range is up to 1000 ft.

Except while charging, the handset does not need to be located near the charging base.

Connecting Telephones to the Control Unit

The way you connect telephones to the control unit depends on the number of telephones you are connecting. For 24 telephones or less, use a direct connection. For 25 telephones or more, use cross-connect fields.

For building cross-connect fields, use one of the following wiring kits:

■

Interconnect Wire. This complete wiring kit contains 110 jack-panel blocks, a template, wiring troughs, D-rings, and D8W cords.

■

Systimax. This complete wiring kit contains 110 termination blocks with modular jacks, a 110A field-termination block, a template, wiring troughs,

D-rings, and patch cords.

Considerations

Review the following items before you begin the procedure:

■

■

If the way you connect the telephones differs from the instructions on the system forms, record each jack and telephone change on Form 2a,

System Numbering: Extension Jacks. See Appendix A, ‘‘System

Numbering Forms’’ .

If you use staples to attach the cords to walls or baseboards, make sure you do not pierce the cords.





Issue 1

June 1997

Page 3-59

■

If an MLX telephone or analog multiline telephone is in a different building from the control unit, and is within 1000 ft. (305 m) of the control unit, connect the telephone to the control unit, using two In-Range

Out-of-Building (IROB) protectors.

Make sure you use an MLX-specific IROB protector for an MLX telephone, and an analog multiline-specific IROB protector for an analog multiline telephone.

■

See the documentation packaged with the IROB protector for complete installation instructions.

If the single-line or T/R telephone is 1000 ft. (305 m) or further from the control unit, connect the telephone to the control unit using an

Off-Premises Range Extender (OPRE).

See the documentation packaged with the OPRE for complete installation instructions.

!

CAUTION:

Take extreme care to make sure that you connect MLX phones only to MLX modules; a mismatch could damage the ports and cause them to stop functioning.

Incorrect wiring can result in users not being able to place outgoing calls. Make sure you use the proper cord. For all GS/LS modules:

■

■

Use a D2R cable from an RJ11 jack.

Do not use the Brand-Rex Quad cable from an E66 block.

If you cannot avoid using the Brand-Rex Quad cable, reverse the tip and ring leads at the E66 block to correct the mismatch.

■

To avoid introducing power supply noise into system wiring, allow at least 3 in. (7.62 cm) of clearance between the basic carrier’s power supply and any wiring or termination hardware located to the left of the control unit.

!

WARNING:

National and local building codes specify the type of cable required for telecommunication wiring. For example, indoor wiring (DIW cable) cannot be used inside or on top of air plenums or ducts, along hot pipes, or across walkways.

Consult your local ordinances and regulations for proper cable selection.

Wiring a Telephone for Two Voice Pairs

If an analog telephone requires either the Voice Announce to Busy feature or voice and data operating independently, use a bridging adapter to assign two adjacent odd/even telephone jacks (for example, 01 and 02, 13 and 14) on an analog telephone module to that telephone. This provides the telephone with

the two voice pairs needed to use these features. See Figure 3-39

.

NOTE:

The numbers of these telephone jacks are boxed on the system forms. In

Figure 3-39 , the label on the bridging adapter refers to the default dial plan

extension number, not the telephone port number.

The even jack on the bridging adapter should be connected to the odd-numbered telephone port, and the odd jack on the bridging adapter should be connected to the even-numbered telephone port.

Removing Damaged Connecting Blocks

Issue 1

June 1997

Page 3-62

In some cases, a connecting block becomes damaged and must be removed.

To remove a damaged connecting block, follow the steps below:

Remove the wires or the patch cord from the connecting block.

■

If you have Interconnect Wiring, use long-nosed pliers to remove the telephone wires, and tag the wires with tape to identify their positions.

■

If you have Systimax wiring, pull off the patch cord.

Place a 788K1 retainer tool against the conductor pairs beneath the connecting block to be removed. See

Figure 3-40 .

Use pliers to grip the connecting block in the center. See

Figure

3-40 .

Move the block gently up and down and pull it out.

If a conductor wire is accidentally pulled from a block, pull it with the long-nosed pliers to get some slack.

Use your fingers to lay the conductor wire back in its slot in the index strip, and then reseat it with the D-impact tool.

Seat the new connecting block by using the 788J1 impact tool.

Replace the telephone wire onto the connecting block.

■

If you have Interconnect Wiring, remove the tag from the telephone wires and use the D-impact tool to reseat the wires.

■

If you have Systimax wiring, attach the patch cord to the connecting block.
