				Connecting to the Network   
					" Procedure   
					To connect your unit to the network:   
					1. Connect one end of the supplied network cable into the rear panel DSL jack.   
					2. Connect the other end to your DSL network interface.   
					NOTE:   
					Do not use a flat VF network cable as this may severely degrade the   
					performance of the termination unit. Use only Cat 5 twisted-pair network   
					cable.   
					A crossover cable (Pins 1 and 2 to 4 and 5) is required to connect two   
					7986 Standalone Termination Units back-to-back.   
					Connecting to a DTE   
					The E1 network interface is either two BNC connectors (Transmit and Receive)   
					for a 75-ohm unbalanced interface, or an RJ48C, 8-position, unkeyed modular   
					connector for a 120-ohm balanced interface. See Cables and Pin Assignments in   
					the User’s Guide for specifications of the 120-ohm connector and cable.   
					Connecting to a System Terminal   
					An optional system maintenance terminal may be attached to your Hotwire 7986   
					Standalone Termination Unit through the modular jack on the rear panel. The   
					system maintenance terminal allows you to view the status of the unit, and   
					change configuration options. The terminal must be a VT100-compatible terminal   
					or a PC running terminal emulation software.   
					" Procedure   
					To connect your unit to a system terminal:   
					1. Connect the 9-pin end of the terminal cable into a COM port on your PC.   
					2. Plug the other end into the modular jack on the rear panel.   
					3. Set the communication parameters on your PC or terminal to:   
					— 9600 baud   
					— 8 bit characters   
					— no parity   
					— 1 stop bit   
					— no flow control   
					Press Enter from your terminal or PC to activate the Main Menu for the attached   
					unit. The system runs diagnostics and status checks. After a few moments, the   
					Main Menu or Logon screen appears on your terminal.

				In a DSLAM-to-standalone configuration:   
					H 
					The devices synchronize without altering factory defaults, since the CO unit   
					defaults to LTU mode, and the CP unit defaults to NTU mode.   
					In a standalone-to-standalone configuration:   
					H 
					One unit must be changed to run in LTU mode, since standalone units have   
					a factory default setting of NTU mode.   
					In both cases the clocking source may have to be altered depending on network   
					requirements.   
					Choosing a Configuration Mode   
					You can make configuration changes either through a VT100-compatible terminal   
					and the unit’s Configuration menus or by manually changing switches on the   
					board. The unit comes configured to allow settings to be made through the   
					Configuration menus.   
					Configuring the Unit Using the Configuration Menus   
					Use the Configuration menu to select, display, or change configuration option   
					settings.   
					NOTE:   
					The 7986 Standalone Termination Unit is preconfigured as an NTU. If you   
					are using this unit as an NTU, the configuration options may not need to be   
					changed.   
					The 7986 Standalone Termination Unit has two sets of configuration option   
					settings:   
					H 
					H 
					The Current Configuration (the 7986 Standalone Termination Unit’s active set   
					of configuration options)   
					The Default Factory Configuration (a read-only configuration area containing   
					the factory default configuration options)   
					To display configuration options, you must first load a configuration into the edit   
					area. To load a configuration option set into the configuration edit area, follow this   
					menu selection sequence:   
					Main Menu → Configuration (Load Configuration From)   
					Make a selection by placing the cursor at your choice and pressing Enter.   
					If you select . . .

					sure of the proper static control precautions, contact your nearest   
					sales or service representative.   
					496-15104   
					" Procedure   
					To configure the unit using internal Switchpacks S1 and S2:   
					1. Power down the unit and disconnect the power supply.

					or included in the manual.   
					2. Input power to this product must be provided by one of the following: (1) a UL   
					Listed/CSA Certified power source with a Class 2 or Limited Power Source   
					(LPS) output for use in North America; or (2) a 24 Vdc National Electric Code   
					(NEC) ANSI/NFPA 70/Canadian Electric Code (CEC) Class 2 circuit installed   
					in accordance with articles 110-16, 110-17, and 110-18 of the NEC, and   
					articles 2-308, 2-310, 2-312, 2-314, 2-200, and 2-202 of the CEC, or (3) a   
					Safety Extra Low Voltage (SELV) power source with a maximum available   
					output of less than 240 VA, certified for use in the country of installation.   
					3. Slots and openings in the cabinet are provided for ventilation. To ensure   
					reliable operation of the product and to protect it from overheating, these   
					slots and openings must not be blocked or covered.   
					4. Do not allow anything to rest on the power cord and do not locate the product   
					where persons will walk on the power cord.   
					5. Do not attempt to install or service this product yourself, as opening or   
					removing covers may expose you to dangerous high voltage points or other   
					risks. Refer all installation and servicing to qualified service personnel.   
					6. General purpose cables are provided with this product. Special cables, which   
					may be required by the regulatory inspection authority for the installation site,   
					are the responsibility of the customer.   
					7. When installed in the final configuration, the product must comply with the   
					applicable Safety Standards and regulatory requirements of the country in   
					which it is installed. If necessary, consult with the appropriate regulatory   
					agencies and inspection authorities to ensure compliance.   
					8. A rare phenomenon can create a voltage potential between the earth   
					grounds of two or more buildings. If products installed in separate buildings   
					are interconnected, the voltage potential may cause a hazardous condition.   
					Consult a qualified electrical consultant to determine whether or not this   
					phenomenon exists and, if necessary, implement corrective action prior to   
					interconnecting the products.   
					9. In addition, if the equipment is to be used with telecommunications circuits,   
					take the following precautions:   
					— 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.   
					— Avoid using a telephone (other than a cordless type) during an electrical   
					storm. There may be a remote risk of electric shock from lightning.   
					— Do not use the telephone to report a gas leak in the vicinity of the leak.
