NSTALLATION
Perform the following steps to install the UTU-701C line unit.
1 Align the UTU-701C with the card guides in the shelf or enclosure (see Figure 9 ).
2 Slide the line unit into the guides, then push the unit inward until it seats firmly in the card-edge connector.
3 Tighten the two captive screws on the UTU-701C front panel to secure the unit in place.
4 If configuring the line unit as an LTU, power up the shelf and proceed as instructed on pages 25 through 27
and 37 to access the Local Unit Role option in the Config System Settings menu (the default setting is NTU).
5 Set the TT clock at the DTE for the default HDSL payload rate of 256 kbps (4 time slots).
Figure 9. Installing the UTU-701C Line Unit
The chassis ground of the shelf or remote enclosure receiving these units must be connected
to earth ground for protection of the equipment and for safety of personnel.
Primary protection for the HDSL line must be provided by the user. Both primary and secondary
protection must be provided by the user if the E1 line runs outside of the building.
