NSTALLATION
1
Align the UTU with the card guides in the shelf or enclosure.
2
Slide the UTU into the guides, then push the unit inward until it seats
firmly in the card-edge connector.
3
Tighten the two screws on the UTU front panel to secure the unit in place.
4
If using the UTU as an LTU, power up the shelf or enclosure and set the
Local Unit Role option to LTU (see
or
“Console Port Configuration Settings” on page
). The default setting for the UTU is NTU.
5
Set the TT clock at the DTE for the default HDSL payload rate of 128

The LTU-configured UTU holds the configuration settings for both itself and
the remote NTU-configured UTU. As the two units synchronize, the LTU
determines if the NTU is the same type (the same model number). If the NTU
is the same type, it is configured with the LTU settings. If the NTU is a
different type, it is configured with factory default settings.
1
Power up the UTU.
2
Confirm the following:
•
The red ALM LED is on and the green SINC LED flashes once per
second as the units self-configure and establish synchronization.
•
After approximately 60 seconds the red ALM LED is off and the
SINC LED is a steady green. The unit is now ready for configuration
through the front-panel virtual DIP switches and/or the console
screen menus viewed from a maintenance terminal.
