ONFIGURATION
After establishing communication with the remote unit, the HDSL system can
be configured and performance can be monitored from the local unit. If the
HDSL link is down, the only parameters that can be changed are those on the
local unit. The LTU provides a special lockout feature that prevents users
connected to the NTU console port from changing the circuit configuration.
When enabled, this feature provides the maintenance terminal connected to
an NTU with a read-only view of the HDSL system.

Through these menus, the HDSL system is configured, monitored, tested, and
its circuit inventory is displayed.

to the line unit’s front panel console port. The pinouts for the console port
and maintenance terminal connectors are shown in
Figure 2 on page 10 .

settings:
•
VT100 Emulation or ANSI (if VT100 is not available)
• Clear the modem initialization string if supported by the terminal

(recommended)
• Data bits: 8
