SETTING UP THE HDSL LINE

The Express L768/L1.5 works over leased or “dry” copper provided by the lo- cal telephone company. See Chapter 4 on page 87 for specifications on maxi- mum distance. If the Express L768/L1.5 is to be used in a back-to-back configuration, the line mode must be different for each unit.

1.Connect a VT 100 async terminal, or personal computer with a terminal emulator running 9600 N-8-1, to the MAINTENANCE port.

2.Hold down the Control key and press R; then press Enter to display the top menu.

3.Using the arrow keys and Enter key to navigate the menu, go to the Con- figuration/WAN/HDSL menu. Enter the line mode as HTU-C or HTU-R. Each end of an HDSL circuit must be of opposite modes.

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 key to go back up the menu tree. When asked to save HDSL parameters, type y.

6.Connect the HDSL line to the RJ-45 jack labeled HDSL on the rear panel. See Appendix D on page 103 for connector pinouts.
