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 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:

HANDLING PRECAUTIONS FOR  
STATIC-SENSITIVE DEVICES  
This product is designed to protect sensitive components from  
damage due to electrostatic discharge (ESD) during normal operation.  
When performing installation procedures, however, take proper static  
control precautions to prevent damage to equipment. If you are not  
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.  
2. Remove the enclosure cover:  
— Insert a small, flat screwdriver blade into the slots on one side of the  
cover and push to free the inner latches  
— Lift off the cover to expose the circuit board  
3. Locate Switchpack S1.  
4. Set Switch 1 on Switchpack S1 to ON to enable Switchpacks 1 and 2.  
5. After you enable the switchpacks, set the switches to your desired  
configuration.  
6. Replace and secure the cover.  
7. Power up the board to reset and enable the new configuration.

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.

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.
