A terminal session is initiated by entering multiple space bar characters which are used by the HFAC to determine the speed of the terminal. Once the speed has been derived, an Introductory Menu is presented as illustrated in Figure 7. This screen includes ADTRAN

technical support phone numbers along with serial numbers, CLEI codes, date of manufacture information for each active HDSL / HDSL2 system element, and if the circuit has an installed HDSL / HDSL2 range extender (HRE / H2R).

NOTE

The command keys valid for each screen are shown at the bottom of the display. Pressing keys other than these may cause the HFAC to adjust to a different speed. If this happens, the HFAC will not respond to keyboard commands and may display random characters. Press the space bar repeatedly until the screen is re-displayed.
