SETTING UP THE SDSL LINE
The Express L768 works over leased or “dry” copper provided by the

line mode must be different for each unit.

terminal emulator running 9600 N-8-1, to the MAINTENANCE
port.

play the top menu.

HTU-C or HTU-R. Each end of an SDSL circuit must be of oppo-
site mode.
4. Set the rate of transfer that will be used. Both devices must be set
at the same rate.
5. Use the left arrow key or the
Escape
