    							To wall-mount the telephones,
    After configuring a telephone for wall mounting, either mount it directly on the wall using two
    #10 pan-head screws (obtained locally), or mount it on a wall jack cover plate. If using a wall
    jack cover plate, use an AT&T type 630B wall plate for best results.
    1. If #10 screws are used, thread them into the wall within 1/8-inch of the surface. Refer to the
    illustration for the spacing dimensions.
    2. Position the keyhole-shaped holes in the bottom of the telephone over the #10 screws or the
    cover plate studs. Slide the telephone down until a slight click is felt.
    3. To remove the telephone, lift to unsnap both screws or studs from the bottom housing, and
    then lift away from the wall.

    							2.6 Installing DSS/BLF Consoles
    The digital telephone system supports the installation and use of DigiTech DD32X,Impact
    IB64X, and Impression DU32X consoles at any available station port. The number of installed
    consoles is limited only by port availability; however, since a console complements a companion
    telephone located in an adjacent station port, you can use up to one-half of the available station
    ports for consoles. In addition, with the dual console feature (discussed later), a full two-thirds of
    the total station port capacity is available for console use.
    You can assign two consoles to one telephone, each taking its own station port. This feature is
    especially useful with DigiTech DD32X and Impression DU32X consoles and a J1632 system
    that has one or two JM408 expansion modules included with it. Thisdual console featureallows
    a station user to monitor up to 48 stations from one station location using 32-button consoles.
    Install the first console at the station port that is logic-paired with the station that you wish to
    complement. Install the second console at any station port except 10 or 11 and, using class of
    service programming, assign it to the same station port that is logic-paired with the first console.

    22–23 38–39 54–55
    24–25 40–41 56–57
    You can install the DSS/BLF console at any station port and assign it to a station without first
    installing a console at the station’s logic-paired port if you wish. This configuration is
    convenient for adding a console to an existing telephone installation that already has its
    logic-paired port occupied; however, do not use this configuration for assigning a console to
    station ports 10 and 12 because the console buttons will not be usable for programming. As
    discussed above, this feature is also useful for adding a second console to a station that already
    has a paired console installed with it.
    The digital telephone system automatically recognizes a console when you connect it to a station
    port and automatically assigns the station intercom numbers to the console buttons for direct
    station selection (DSS) purposes with associated busy lamp field (BLF) status lights. However,
    the console buttons are fully programmable and the station user can customize them as he or she
    sees fit by programming them as DSS buttons or as automatic dialing (autodial) buttons.
    When the user programs the buttons for DSS use, autodial capability is also available at a
    secondary level at each DSS button.
    IMI66–132 DSU II Digital Telephone System
    2 – 26  Installing The DSU II Digital Telephone System 
    						
    							While the first console (the one installed at the logic-paired port) extends the autodial buttons of
    the paired telephone by 48 and provides DSS/BLF coverage for station ports 10 through 57, the
    second console (the one installed at the programmed station port) provides DSS/BLF coverage
    as follows:
    ·On a 32-station system with two 8-station expansion modules, the first 16 buttons are
    automatically assigned (defaulted) to station ports 42 through 57 for DSS purposes.
    ·On a 32-station system with one 8-station expansion module, the first 8 buttons are
    automatically assigned (defaulted) to station ports 42 through 49 for DSS purposes.
    ·On any other smaller station capacity system, all buttons are unassigned.
    When you install a console and program it to complement a telephone without first having a
    console installed at a port that is logic-paired to that telephone, its button assignment is
    automatically defaulted, as described above, but the user can reprogram it as required. It is
    important to remember that when you program for a second console, the system sets the console
    button mapping to that which is described above. When you clear the assignment, the system
    resets the button mapping to match a logic-paired console. This means that when you clear the
    second console feature, the console installed at that port complements the telephone that is
    installed at its logic-paired port instead of the telephone that is located at the program-designated
    port, and its buttons are automatically reassigned to station ports 10 through 57.

    							2.7 Connecting A Power Failure Station
    The system provides a tip and ring pair connected to line 1 as an emergency power failure
    circuit. This circuit is active during a commercial AC power failure if an external battery
    assembly is not installed to provide battery back-up power to the system. Connect an industry
    standard, single-line telephone, such as a model 2500, to a power failure pair and use it to
    provide communications capability until the AC power to the system is restored.
    NOTE: The system also provides one power failure connection with each add-on expansion
    module.

    							2.8 Using The Auxiliary Equipment Interface
    You can connect an industry-standard telephone or a data device such as a modem or a FAX
    machine on a line ahead of the common equipment if you wish. If you do so, the system can
    detect an off-hook condition in the connected device and turn on the line status light at the
    system telephones to indicate that the line is busy.
    Connection is across tip and ring of lines 2 and 4. The system provides the auxiliary interface
    connections at terminals 1 and 6 of common equipment line jacks 1 and 2.
    NOTE: When you are employing this auxiliary interface feature, the line-to-line port
    reassignment feature (Section 2.4.2 ) works as described except in regard to line 2
    and line 4. You can only reassign Line 2 to line port 4 and line 4 to line port 2.

    							2.9 Connecting The Common Audible
    And Auxiliary Ringing Interface
    You can use the relay closure dry-contact points for controlling external audible equipment.
    These contact closures track the pattern of the ringing for incoming calls. The contacts are closed
    during the ringing period and are open during the silent period.
    CAUTION
    Do not exceed a 1 amp at 24 volts (0.5 amp at 48 volts) load on these control terminals. If the
    load requirements exceed this limit, connect the load through an external slave relay. DO
    NOT CONNECT THESE CONTROL TERMINALS DIRECTLY TO THE 117VAC LINE.
    2.9.1 Connecting Outside Lines
    Common audible terminalsprovide a dry-contact closure whenever any of the outside lines that
    you have connected to the common equipment ring with an incoming call.
    2.9.2 Connecting Selected Ports
    Station 17 audible terminals provide a dry-contact relay closure whenever ringing is sent to
    station 17 or to a programmable destination. Use class of service programming to choose either
    the station 17 or the programmable paging port as the ringing destination. Refer to Chapter 3 for
    programming details.
    When you have programmed for station port 17 ringing, it is a common practice to use a
    customer-supplied external device to provide loud ringing and connected in a manner similar to
    the common audible arrangement shown in the illustration on the next page.
    CAUTION
    Do not connect an external paging device or any external ringing device to station port 17
    connections.
    When you have programmed for paging port ringing, it is a common practice to use a
    customer-supplied external paging amplifier connected to the paging port to amplify and
    broadcast the ringing tones sent to the paging port by the system. You can employ the relay
    closures that appear at the ringing terminals to energize the external paging amplifier during the
    periods when the ringing tones are being sent if necessary.
    NOTE: Refer to Section 2.10 for a discussion of external paging amplifier connections and
    information for using the paging port ringing terminals in an alternate paging enable
    function.
