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. 315/16 Wall Plate - OR - #10 Screws NOTE: AT&T 630B wall plate is recommended for secure mount.

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.

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.

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. 37 38 39 40 41 42 43 44 45 46 47 48 49 50 { Power Failure Jack (pins 3 & 4) (16-Line, 32-Station Base Unit) Power Failure Terminals on Station Connection Block (4-Line, 8-Station and 8-Line, 16-Station Base Units) DSU221 Typical Industry Standard Non-electronic Telephone (Power Failure Interface) Typical Industry Standard Non-electronic Telephone (Power Failure Interface) Pin 3 = Power Failure Tip Pin 4 = Power Failure Ring 1 2 3 4 5 6 Making A Power Failure Connection IMI66–132 DSU II Digital Telephone System 2 – 28 Installing The DSU II Digital Telephone System
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. { { DSU210 1 2 3 4 5 6 1 2 3 4 5 6 Auxiliary Interface for Line 2 TIP 2 Line Jack 1 Line Jack 2 TIP 4 RING 4RING 2 Auxiliary Interface for Line 4 Optional non-key system telephone device or data device.

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.
