Figure 3. COMSPHERE
3000 Series Carrier (Rear)
If the Shared Diagnostic Control Panel (SDCP) is installed and if the modular DSU’s carrier and slot is
the one selected at the SDCP, the LCD displays the message Power-up Tests. Upon completion of the
tests, the LCD momentarily displays messages indicating that each device (DSU, MUX, and DBM, if
installed) has passed the power-up test.
Reinstall the factory configuration options (use the FacC configuration for a control or FacT for a
tributary).
12. Perform a DSU Device Test from the SDCP to ensure that the modular DSU-TDM combination is
functioning properly. If the test fails, call your service representative for assistance. If the test passes,
continue with this procedure.
13. Make any desired configuration option changes in the DSU, Diag, DBM, Gen, Bckup, MUX, and
LPDA-2 option sets. For information on these option sets, see the COMSPHERE 3600 Series Data
Service Units, Models 3610 and 3611, Time Division Multiplexer, Multichannel Multipoint, and Digital
Bridge Options, Applications Guide, Document Number 3610-A2-GB41.
