The following items should be noted:
■
Loss of one power feeder does not cause a loss of service.
■
All supply voltages other than
−
48 V required by the DDM-2000 OC-12
Multiplexer are generated by DC-to-DC converters within the DDM-2000
OC-12 shelf.
■
The DDM-2000 OC-12 Multiplexer meets all performance requirements
when the DC input voltage varies between
−
40.0 V and
−
60.0 V.
■
The DDM-2000 OC-12 Multiplexer tolerates DC input voltages between
0 V and
−
60 V without damage.
■
The DDM-2000 OC-12 Multiplexer complies with electrical noise tolerance
requirements in Section 13.2 of TR-TSY-000499.
