The following items should be noted:
■ The DDM-2000 OC-3 shelf accommodates two −48 V power feeders
("A" and "B" office power feeders).
■ Loss of one power feeder does not cause a loss of service.
■ All supply voltages other than −48V required by DDM-2000 OC-3
Multiplexer are generated by DC-to-DC converters within the DDM-2000
OC-3 shelf.
■ The DDM-2000 OC-3 Multiplexer meets all performance requirements
when the DC input voltage varies between −40.0 V and −60.0 V.
■ The DDM-2000 OC-3 Multiplexer tolerates DC input voltages between
0 V and −60 V without damage.
■ The DDM-2000 OC-3 Multiplexer complies with electrical noise tolerance
requirements in Section 13.2 of TR-TSY-000499.
