Overview Installing the control unit involves the following, which this chapter describes in detail: 1. Installing the backboard 2. Meeting the power and grounding requirements 3. Checking the total unit load 4. Installing the basic carrier 5. Installing any expansion carriers specified for the system 6. Installing the power supply 7. Installing the processor 8.
Installing the Control Unit 9. Connecting the control unit to AC power 10. Powering up the system 11. Powering down the system Be sure to follow these procedures in the order specified. Preparation The control unit must be installed on a backboard, which may already be installed. If so, skip to the section, “Power and Grounding.” If backboard installation is your responsibility, follow the procedures in this section. Environment The placement of the control unit requires careful consideration.
Installing the Control Unit Table 2-1. Environmental Requirements Operating Temperatures 40° - 104°F (4° - 40°C) Optimum temperature: 60°F (15.6°C) Humidity 20%-80% Airborne Contamination Do not expose the control unit to moisture, corrosive gases, dust, chemicals, spray paint, or similar material. Ventilation Allow at least 1 inch (2.54 cm) on the right and left sides of the control unit and 12 inches (31 cm) above and below to prevent overheating.
Installing the Control Unit Radio transmitters (AM or FM), television stations, induction heaters, motors (with commutators) of 0.25 horsepower (200 watts) or greater, and similar equipment are leading causes of interference. Small tools with universal motors are generally not a problem when they operate on separate power lines. Motors without commutators generally do not cause interference. Field strengths below 1.0 volt per meter are unlikely to cause interference.
Installing the Control Unit Backboard Requirements The backboard should be wide enough to accommodate additional carriers if system growth is anticipated. In addition to the basic carrier, two expansion carriers can be added.
Installing the Control Unit NOTE: The combined pullout force of the backboard should be at least 650 pounds (295 kilograms). Power and Grounding Proper power and grounding are essential for correct and safe functioning of the system. Use this section to verify that all power and grounding requirements are met.

Installing Telephones and Adjuncts Figure 3-33. Connecting Termination Blocks to Field-Terminated Blocks Wire a Telephone for Two Voice-Pairs If an analog telephone requires either the Voice Announce to Busy feature or the Simultaneous Voice and Data feature, use a bridging adapter to assign two adjacent odd/even telephone jacks (01 and 02, 13 and 14, etc.) on an analog telephone module to that telephone. This provides the telephone with the two voice pairs needed to use these features. See Figure 3-34.
Installing Telephones and Adjuncts NOTE: The numbers of these telephone jacks are boxed on the system forms. In Figure 3-34, the label on the bridging adapter refers to the default intercom number, not the telephone jack number.

Installing . Telephones and Adjuncts Terminate Cable at a Telephone Outlet There are many kinds of telephone outlets, which are fundamentally all the same. Some are surface-mounted, affixed directly onto a wall surface, and others are flush-mounted, where the jacks are located inside a wall housed in a regular electrical box. On the workstation side, a cord plugs into the jack; on the closet side, the DIW cable is hard-wired to the outlet.

Press the clips back on over the wires. 8. Strip off the protective paper from the adhesive strips and press them onto the back of the outlet. 9. Press the outlet onto the wall. 10. For additional security, screw the outlet to the wall. 11. Screw the parts of the outlet together.
Installing Telephones and Adjuncts Label the System Wiring If done correctly, labeling can provide valuable information about the location of wire or cable within the building and save hours of frustrating work. There are five types of labels used for identification: ■ Cable labels are white adhesive-backed tabs that are stuck to the cables to identify the source and the destination of the cables before they are pulled to and terminated in satellite closets and equipment rooms.

If a system has customized labels for the auxiliary system, use them.
Installing Telephones and Adjuncts 4. Mark the box with the letter of the closet to which the DIW cable is pulled and with the circuit number of the wire. This is the same as the number you wrote on the wire sheath. Wire 1 becomes circuit 1; wire 2 becomes circuit 2. 5. At the boxes next to the offices, pull out enough wire to reach the wall jacks. Allow plenty of slack. Cut the wire and mark the end of the DIW cable with the closet letter and the circuit number. 6.
Installing Telephones and Adjuncts Checking Poorly Labeled Wiring If you do not understand the labeling system used or a label is missing or damaged, use a tone device and a telephone handset to match like cables. Hardware ■ tone device ■ telephone handset ■ telephone cord with an 8-pin modular plug ■ 4-pair patch cord Tools ■ diagonal pliers or wire strippers Procedure 1. Insert the 8-pin of the telephone core into an oulet on the floor area. 2.
Installing Telephones and Adjuncts 8. Using the diagonal pliers or wire strippers, cutoff the other end of the patch cord and expose the pairs. Do not cut off too much of the cord because you’ll need the length to test the top rows of the cross-connect field. 9 . The handset also has two clips with “teeth” that extend from its base. Attach the clip of the handset to the exposed wires of the patch cord. Set the switch on the side of the handset to MONITOR. 10.

Replace the telephone wire onto the connecting block.
Connecting the Control Unit to the Network Interface 4 To connect the control unit to the network interface side, the method of connection depends on the type of network interface that is installed. While there are many ways to connect the network interface to the control unit, the methods in this chapter are preferred.
Connecting the Control Unit to the Network Interface CAUTION: ■ The telephone company is responsible for providing appropriate protection for central office trunks. Do not connect the central office trunks until you are certain that they are properly protected. See the section, “Central Office Trunk Protection,” in Chapter 2 for details.
Connecting the Control Unit to the Network Interface The adapter needed to connect the central office trunks to the control unit depends on the type of network interface, as shown in Table 4-1. Table 4-1.

Connecting the Control Unit to the Network Interface RJ21X Wiring Field Procedure Follow this procedure to connect the RJ21X network interface to the control unit: 1. Drill two diagonally opposite holes into the backboard for each piece of hardware. Keep a 1/16-inch (1.6 mm) space between each piece of hardware. 2. Mount the wire troughs and the termination blocks. There is a wire trough above and below each termination block. 3. If necessary, repeat steps 1 and 2 for a second column. 4.
Connecting the Control Unit to the Network Interface Figure 4-4. Using the D-Impact Tool to Seat the Conductors 9. Label the network interface jacks, control unit module jacks, termination blocks, and D2R cords (see “Labeling Trunks” later in this chapter). 10. For each trunk, plug one end of a D2R cord into the designated jack on the termination block and the other end into the trunk jack on the proper control unit module. NOTE: The modular jacks on the termination block are 8-wire jacks.
Connecting the Control Unit to the Network Interface CAUTION: Do not plug an analog multiline telephone, an MLX telephone, or anything else from the telephone side of the control unit into this wiring field; doing so will busy-out the trunk. RJ11 and RJ14 Interfaces The RJ11 and RJ14 interfaces are connected similarly, with the following differences: ■ RJ11 connects one central office trunk per jack ■ RJ14 connects two trunks per jack Plug a 267C-type adapter into each RJ14 jack.
Connecting the Control Unit to the Network Interface RJ11 and RJ14 Network Interface Hardware ■ D2R cords CAUTION: Incorrect wiring can damage the ports and cause them to stop functioning. Make sure you use the proper cords. For all GS/LS modules, do the following: — Use a D2R cable from an RJ11. — 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.
Connecting the Control Unit to the Network Interface RJ2GX Interface The RJ2GX interface is a 25-pair amphenol connector that interfaces up to eight tie trunks. You construct the cross-connect field in the same way as for the RJ21X interface (see “RJ21X Interface” earlier in this chapter). RJ21X and RJ2GX interfaces do not require separate termination blocks. If there is room on the termination block for the trunk wires, both the RJ21X and the RJ2GX can be punched down on the same 110AB1-100JP12 block.
Connecting the Control Unit to the Network Interface Testing Trunks Before connecting the central office trunks to the control unit, verify that a dial is being received and that you can dial out on every trunk. CAUTION: Do not use analog multiline telephones or MLX telephones for testing. They do not work for these tests and can be damaged if you use them for this purpose. DID trunks can be tested only through the control unit; do not test DID trunks at this time.
Connecting the Control Unit to the Network Interface Test Ground-Stat Trunks To perform this test, you need a single-line telephone with a ground key or a ground-start button. NOTE: If a single-line telephone with a ground key (or ground-start button) is not available, ground one side of a trunk. 1. Plug the single-line telephone into each central office trunk jack (either at the network interface or at the cross-connect field). 2. Pick up the handset. You should hear a dial tone. 3.
Connecting the Control Unit to the Network Interface Labeling Trunks You can have up to 80 central office trunk jacks on the communications system (1 to 80). Follow this procedure to label each D2R or D8W cord, network interface jack, and control unit module jack. Procedure: Labeling Trunks 1. Review the System Form 2c, System Numbering—Trunk Jacks to determine each central office trunk assignment on the control unit. 2.
Connecting the Control Unit to the Network Interface Installing the Channel Service Unit The channel service unit (CSU) provides the interface between the 100D module and the DS1 facilities. NOTE: Before the CSU can be installed, the local telephone company must be contacted for information such as services available, equipment options, and 48-VDC power on the trunk.
Connecting the Control Unit to the Network Interface Step 1: Setting the CSU DIP Switches Set the CSU DIP switches as indicated on Form 3b, Incoming Trunks—DS1 Connectivity (100D Module). The seven 8-position DIP switches on the rear panel of the CSU are set for operating features and diagnostic tests: ■ SW1 sets the CSU address, which must be confirmed with the local telephone company (see Table 4-3 for the default settings).

Connecting the Control Unit to the Network Interface 551 T1 CSU The 551 T1 CSU performs many of the same functions as the ESF T1 CSU except for the following: ■ B8ZS is not supported. Therefore, the 64-kbps clear channel is not supported. ■ Extended superframe (ESF) format is not supported. if a network requires this format, the ESF T1 CSU must be used.
Connecting the Control Unit to the Network Interface Installing the 551 T1 CSU involves the following: 1. Setting the CSU DIP switches 2. Mounting the CSU in a relay rack or on a shelf as a stand-alone unit 3. Connecting the CSU to the network interface 4. Inserting the signal monitor unit 5. Inserting the office repeater 6. Connecting the CSU to the 100D module 7.
Connecting the Control Unit to the Network Interface Signal Monitor Unit Switch Settings There are four option switches in the signal monitor unit (see Figure 4-10). These switches govern the operation of the following options: ■ ONES causes the unit to transmit an ALL ONES keep-alive signal to the central office when the customer signal drops below the minimum average ones-density.
Connecting the Control Unit to the Network Interface Office Repeater Switch Settings Table 4-22 and Table 4-23 show the power mode and artificial line-option settings for the office repeater. See Figure 4-11 for the location of the optionsetting screws. Table 4-22.
Connecting the Control Unit to the Network Interface Step 3: Connecting the CSU to the Network Interface The terminal block (TB1) on the back of the CSU is the connecting point for T1 service lines, fault wires, and Ioopback wires. Also, if a local power supply is used, the TB1 is the termination spot for the power supply wires. WARNING: Voltages as high as 260 V can occur between the transmit and receive pairs of the T1 line.
Connecting the Control Unit to the Network Interface c. Connect the DC Ioopback pair (if provided by the local telephone company) to terminals 11 and 12. d. If the CSU is to be locally powered, connect the power supply leads to terminals 14 and 15. Step 4: Inserting the Signal Monitor Unit After setting the option switches, plug the signal monitor unit into the right side of the 551 T1 CSU. The signal monitor unit has six LEDs and six bantam jacks (see Figure 4-10).

Connecting Data Equipment 6 This chapter explains how to set up data stations and modem pools. A data station is a data terminal that sends and receives data (and voice if the station includes a telephone). If the system includes both analog and digital data stations that need to communicate with each other, a modem pool is required. See Figure 6-1. CONTROL UNIT DIGITAL DATA STATION ANALOG DATA STATION MODEM POOL Figure 6-1.
Connecting Data Equipment Data Stations A data station is a combination of equipment, possibly including a telephone, PC, printer, or fax machine. If the data station sends and receives analog data, it requires a modem to convert the signal from digital to analog or from analog to digital. If, however, the data station sends and receives digital data, it requires a data module instead of a modem.
Connection Data Equipment Digital Data Stations Depending on the customer’s needs, the system supports the following types of digital stations: ■ Digital data and digital voice (digital data terminal and MLX telephone) ■ Digital data only (simultaneous voice and data is not permitted) NOTE: ■ PRI trunks are required to send and receive data to and from digital data stations that are external to the system. ■ See Table 6-1 for a detailed comparison of data station configurations.
Connecting Data Equipment Data Station Equipment Configurations Table 6-1 shows the equipment configuration for each type of data station. Table 6-1.
Connecting Data Equipment NOTE: ■ The first data station type (analog data and analog voice) requires a bridging adapter to connect the telephone to the two adjacent ATL station jacks. ■ The last data station type (digital data only) requires a terminating resistor adapter to connect the data module to the MLX station jack. ■ See “Video Conferencing Data Stations” for the type of information indicated in Table 6-1. ■ The maximum cord length from the data module to the telephone is 80 ft (24 m).
