Installing The Conference Board In The DXP Plus Digital Communications System 1.0 Introducing The Conferencing Board The software timing for the DXPPlussystems, dedicates 32 time slots for conferencing operations. Different types of conferencing actions require different quantities of time slots as detailed in the following list: ·SOHVA = 3 time slots,·Service Observing = 3 time slots, ·Executive Override = 6 time slots,·Three-Way Conference = 6 time slots, ·Four-Way Conference = 8 time slots,·Five-Way Conference = 10 time slots, ·Six-Way Conference = 12 time slots,·Seven-Way Conference = 14 time slots. The maximum conference combinations that the system allows at any one time are as follows: ·three five-way or one five-way Plus 2 SOHVA,·one four-way Plus two three-way, ·five three-way or four three-way Plus one SOHVA,·four four-way, ·two six-way,·two seven-way The optional conference board adds the capability for five additional three-way conferences. These are three-way conferences consisting of three stations or two stations and one line. These additional three-way conferences do not provide additional SOHVA or service observe capability. When you install the conference board, the system uses its capacity of three-way conferences before using the main system resources for additional conferencing. 1.2 Complying With Underwriters Laboratories Regulations Per The Underwriters Laboratories regulation 1459, 2nd edition, be aware of the following precautions when installing telephone equipment that is to be directly connected to the telephone company network: ·Never install telephone wiring during a lightning storm. ·Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. ·Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. ·Use caution when installing or modifying telephone lines.

2.0 Installing Circuit Boards CAUTION Circuit boards are susceptible to damage caused by electrostatic discharge, and you must keep this fact in mind as you handle the circuit boards. Refer to the Comdial publication IMI01-005,Handling Of Electrostatically Sensitive Components, for general information. Specific handling precautions are also included in this installation instruction. 2.1 Creating A Static Safe Work Area When servicing the common equipment cabinet at the installation location, it is a good practice to place a conductive mat in front of the cabinet area and ground the mat to a good earth ground. (The third wire ground of the AC power line is also an acceptable grounding point.) The grounded conductive mat provides a safe static electric discharge path. When removing the common equipment cabinet from the installation location for servicing, it is a good practice to prepare a static-safe work area on which to place the cabinet. You should supply yourself with a static discharge wrist strap, and wear it every time you handle electronic circuit boards either at the cabinet mounting location or at your work area.

2.2 Installing Conference Boards In The Equipment Cabinet Install one or more conference boards (as needed) in any unused universal board slots. 1. Normally you should disconnect the AC power cord from the AC outlet and disconnect the optional battery back-up assembly from the main cabinet power supply; however, when necessary, you can install a DXCNF board in an operating system. If you must do this, connect one end of a standard telephone handset coil cord to the precharge port on the power supply. During step 6, you will connect the other end of this coil cord to the precharge jack on the station board. 2. Install your static discharge wrist strap on your bare wrist; adjust it for a snug fit. Be sure that the strap is touching bare skin and is not isolated by clothing. Connect the wrist strap cord between the wrist strap and an AC or earth ground NOTE: With the common equipment in the installed position, the ground lug on the side of the cabinet is an appropriate grounding point since it should have a heavy ground wire connected between it and a good earth ground. 3. Loosen the retaining hardware, and lift the front panel away from the common equipment. 4. Each conference board is supplied in a static protection bag for safe keeping. When you are ready to install the circuit board, remove it from its static protection bag. 5. Locate an unused board slot for conference board installation. NOTE: On DXP Plus systems, do not install a conference board at the right-most board slot in the second (or lower) expansion cabinet. The system reserves this slot for internal use. 6. If you are installing the conference board in an operating system, connect the free end of the precharge cord that you installed in step 1 to the precharge jack on the station board. 7. Orient the conference board with its top and bottom guides in the cabinet’s board cage. and press the board firmly until its board edge connection properly mates with the connector on cabinet’s backplane. CAUTION When pressing circuit boards into place, press them only at the extractor lever locations. If you apply pressure at other locations you may damage the board assembly. 8. Repeat steps 4–7 until all circuit boards are installed. 9. Make a final inspection to ensure that the conference board is oriented correctly and mated properly. 10. Install and tighten the supplied screws to secure the conference board to the board cage. 11. Plug the AC line cord into the AC outlet, reconnect any battery back up equipment, and turn on the switch on the power supply. 12. Replace the front panel on the common equipment cabinet.

Installing The DXOPT–COM Communications Card In The DXP Plus Digital Communications System 1.0 Understanding The Communications Card The communications card provides serial data ports for interfacing such items as open architecture interface applications, PC attendant positions, and the SMDA data printer. NOTE: The serial data ports located on the CPU board are dedicated to PC-based programming and the remote maintenance modem. You can install communications cards on the services board, the expansion cabinet interface boards, and the main cabinet’s auxiliary board. Each of these boards will accept two communications cards in its lower two slots. The DXPPlussupports a maximum of 18 serial data ports. Two of these ports are the dedicated ports provided by the CPU board while communications cards provide the remaining 16 undedicated ports. The system designates serial data ports 3–18 to specific locations as detailed in the following chart. Serial Data Port Designation* DXOPT–COM Location Serial data ports 3–10 Lower two slots on the services board Serial data ports 11–18Lower two slots on one of the three following locations: — the upper expansion cabinet interface board — the lower expansion cabinet interface board — the auxiliary board installed in the main cabinet. You must take programming action to match the data port number with the installation location that you choose for the communications card. *The full compliment of 16 undedicated serial data ports requires four installed communications cards. 1.1 Communications Card Connections The interface connector between the external device and the communications card is a standard modular jack, and each serial data communications port supports various baud rates, data bits, stop bits, parity, and flow control. You can program these various options using data base programming.

3.0 Installing The DXOPT-COM Card You can install up to four communications cards to attain a maximum of 16 serial data ports. You can install these cards in the lower two slots of the services board, the expansion cabinet interface boards, and the main cabinet’s auxiliary board. ·The best, and recommended, choice is to add communications cards to the services board. ·The second best choice is to add communications cards to either or both expansion cabinet’s interface boards if one or both are available. ·The third choice is to add an auxiliary board to the system and install communications cards on it. This is the least desirable choice because it requires you to occupy a board slot that you could otherwise use for line or station boards. 1. Be sure you are standing on the conductive mat that you have placed in front of the cabinet area and grounded to a good earth ground. (The third wire ground of the AC power line is an acceptable grounding point if the AC wall jack is properly grounded.) The grounded conductive mat provides a safe static electric discharge path. 2. Install your static discharge wrist strap on your bare wrist; adjust it for a snug fit. Be sure that the strap is touching bare skin and is not isolated by clothing. Connect the wrist strap cord between the wrist strap and an AC or earth ground NOTE: With the common equipment in the installed position, the ground lug on the side of the cabinet is an appropriate grounding point since it should have a heavy ground wire connected between it and a good earth ground. 3. Disconnect the AC power cord from the AC outlet and disconnect the optional battery back-up assembly from the cabinet power supplies. 4. Loosen the retaining hardware and remove the host circuit board, or boards, from the equipment cabinet, place it in a static protection bag, and transport the board to the static-safe work area. 5. At the static safe work area, with your wrist strap in place, remove the host circuit boards and the communications cards from their respective static protection bags. 6. Referring to the illustrations on the next page, orient the host circuit board and the communications card, and attach them with the supplied hardware. 7. Place the host circuit board and its newly installed communications card into a static protection bag and transport this assembly back to the common equipment cabinet. 8. With your static strap on your wrist, remove the board assembly from the static protection bag and install the board in its designated board slot. CAUTION When pressing circuit boards into place, press them only at the extractor lever locations. If you apply pressure at other locations you may damage the board assembly. 9. Make a final inspection to ensure that the board assembly is oriented correctly and mated properly. 10. Install and tighten the supplied screws to secure the circuit board assembly to the board cage. 11. Plug the AC line cord into the AC outlet, reconnect any battery back up equipment and switch on the power supply. 12. Replace the front panel on the common equipment cabinet.
