ONFIGURATION
A maintenance terminal is used to access the line unit console screens and
configuration menus. Through these screens and menus, the HDSL system is
configured, monitored, tested, and its circuit inventory can be displayed.
The console screens must be viewed through the HMU-319 or Operating
System (OS) port located at the back of the Wideband System 3190, or
through a Trivial File Transfer Protocol (TFTP) session over an Ethernet
Local Area Network (LAN) connected to the chassis. The console screens
cannot be accessed through the HLU-819 because this model does not
provide a craft port.
After HDSL establishes communication with the remote unit, the HDSL
system can be configured and performance monitored from the HMU-319
management unit. Both the HLU-819 and UTU-814 are configured at this
time from the same maintenance screens. If the HDSL link is down, the only
parameters that can be changed are those on the local unit.
The HLU-819 provides a special lockout feature that prevents users
connected to the remote maintenance terminal from changing the circuit
configuration. When blocked, the maintenance screens are not accessible
from the remote craft port.
