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 craft port or
Operating System (OS) port located at the back of the Wideband System
3190, or through a TELNET session over an Ethernet Local Area Network
(LAN) connected to the chassis. The console screens cannot be accessed
through the ELU-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. The ELU-819 and UTUs 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 ELU-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.
