6.2 LED Indication on the Display

The display at the front of the SPU contains LED's to visualize the status of
the power, connection and performance of the meter. Please see the
Operation and Maintenance Manual of your particular meter for detailed
information.
7 Optional DSL Modem
For DSL communication the SPU must be equipped with the optional DSL
modem (Figure 5-1) behind the field terminal board (Figure 2-3). Wiring of
the DSL communication to the UFM should be done as described in Table 4
(p.15).
In the 'control room', it is recommended to use the VDD DSL modem
designed by Elster. Detailed information about this modem can be found in
the External VDSL Range Extender User Manual. The PDF version is
available online at http://www.docuthek.com/ , otherwise please refer to
 Appendix I – References at the end of this document for more information.

7.1 Switches

The DSL modem contains 4 DIP switches (see Figure 7-1), whereby the
DSL communication can be fine-tuned and aligned. The external VDD DSL
modem also contains these 4 DIP switches. For optimal communication
ensure both modems are aligned, as described below.
