Connecting to a System Terminal
An optional system maintenance terminal may be attached to your Hotwire 797x
Standalon e Termination Unit through the modular jack on the rear panel . The system
maintenance terminal allows you to vi ew the status of the unit and chan ge configuration
options . The terminal must be a VT100-compatible terminal or a PC running terminal
emulati on software.
Procedure
To connect your unit to a system terminal:
1. Connect the 9-pin end of the supplied terminal cab le into a COM port on your PC.
2. Plug the other end in to the modular jack on the rear panel.
3. Set the communication parameters on your PC or terminal to:
— 9600 baud
— 8 bit char acters
— no parity
— 1 stop bit
— no flow control

operating wit h firmwar e V02.03. 2 or great er and the Model 7976-A2 endp oin t must be
operating with firmware N02.03.2 or greater. In lower firmware versions (N.02.03.05
and below), the pa yl oad rat e is only select ab le at a DSL line ra te of 144 Kbps while al l
other rates default to the maximum, dependi ng on the DSL line rate selected.
