2.2.5 Management Clock Card (MC01)
MC01 card provides the interface between the system and the network
management system. It coordinates with the network management system
to control each card of the equipment and realizes the communication
between the equipment.
MC01 card is used to process 2 optical supervisory channels at each site.
The OSC interface uses LC dual-fiber SFP module or single-fiber SFP
module.
MC01 supports interconnection communication between network elements
through DCC channels.
MC01 provides clock source for the system.
HT8000-II/HT8000-VI supports MC01 card backup protection.
MC01 provides 1 NM interface, 2 EXT interfaces, 1 CONSOLE interface,
1 BITS external clock input/output interface, 1PPS TOD interface, 2 OSC
interfaces, 4 LEDs, 1 reset button and a set of 2-position dip switch. The
