An OptiX OSN 550 NE can automatically save its NE ID, extended ID, IP address, and subnet mask toits backplane. After a new system control, switching, and timing board replaces an original one, the NEautomatically uses the saved information. Therefore, you do not need to set the NE ID, extended ID, IPaddress, and subnet mask for the substitute board.
InstallationModeThe equipment can be deployed in a variety of scenarios and on several different types ofcabinets and surfaces. such as in an ETSI or 19-inch cabinet, APM30H outdoor cabinet, oropen rack, or on a wall or desk.

rs tunnels Bidirectional: 512NOTE One bidirectional MPLS tunnel is counted as two unidirectional MPLS tunnels. If MPLS tunnels do not carry PWs, the sum of PWs and MPLS tunnels must
not exceed 1K. If MPLS tunnels carry PWs, the MPLS tunnels are not countedand the number of carried PWs must not exceed 1K. Therefore, if each MPLStunnel carries one PW, the number of MPLS tunnels and the number of PWscan both be 1K.

System Control and Communication UnitThe system control and communication unit consists of the CPU unit and logic control unit.The system control and communication unit performs the following functions: The CPU unit performs the following control functions using the control bus:
Manages other boards and the other units on the PCX, and collects alarms and performance events. Implements software loading by reading information from the CF card.
The CPU unit processes network management messages in DCCs using the logic controlunit.
The CPU unit communicates with the NMS by its Ethernet NM port. The logic control unit decodes the address read/write signals from the CPU unit and
enables FPGA loading.

The logic control unit cross-connects the overheads between the auxiliary interface unit,the CPU unit, and other boards. This helps to achieve the following purposes:
Adding or dropping DCC information processed by the CPU unit Adding or dropping orderwire and synchronous/asynchronous data services Exchanging the orderwire bytes, DCC bytes, and K bytes between different lines
The system control and communication unit on a PCX board communicates with thesystem control and communication unit on the standby PCX board by carrying FEsignals over the communication bus in the backplane. In this manner, the active andstandby PCX boards form a 1+1 hot backup relationship.
Packet Switching UnitThe packet switching unit grooms services and processes protocols for packet services. After receiving services from a packet service board, the packet switching unit grooms
the services based on the configurations delivered by the system control andcommunication unit.
After receiving protocol packets from a packet service board, the packet switching unittransmits the protocol packets to the system control and communication unit forprocessing. After processing, the system control and communication unit sends theprotocol packets back to the packet switching unit. The packet switching unit transmitsthe protocol packets to the packet service board.
TDM Cross-Connect UnitThe TDM cross-connect unit grooms TDM services over the entire system using the higherorder cross-connect module and the lower order cross-connect module. Figure 3-2 shows thefunction block diagram of the cross-connect unit.

The source TDM service unit transmits VC-4 signals to the higher order cross-connectmodule over cross-connect buses. If the VC-4 signals carry only VC-4 services, the higherorder cross-connect module processes the VC-4 signals and then transmits the signals to thesink TDM service unit. If the VC-4 signals include VC-12 or VC-3 services, the higher order

cross-connect module grooms the VC-12 or VC-3 services to the lower order cross-connectmodule. The lower order cross-connect module processes the VC-12 or VC-3 services andthen transmits the services back to the higher order cross-connect module. The higher ordercross-connect module processes the services and then transmits the services to the sink TDMservice unit.
Clock Unit The clock unit selects an appropriate clock source from service clock sources at service
ports based on clock priorities. Locking the clock source by means of the phase-lockedloop, the clock unit provides the system clock to other units on the PCX and otherboards.
The clock unit receives IEEE 1588v2 messages and IEEE 1588 ACR messages from theGE/10GE signal access unit, and performs protocol processing to achieve clock/timesynchronization.
The clock unit supports synchronous Ethernet clock. The clock units on the active and standby PCX boards transmit clock signals to each
other.
Packet Processing UnitThe packet processing unit receives/transmits and processes 1xGE/10GE optical signals. In the receive direction:
After performing optical-to-electrical (O/E) conversion, decoding, and serial/parallel conversion forGE/10GE optical signals, the GE/10GE signal processing unit extracts framed GE/10GE signals bydelimiting frames and adding preambles. The GE/10GE signal processing unit also performs cyclicredundancy checks (CRCs).
The GE/10GE signal processing unit works with the packet switching unit to process VLAN tags inEthernet data frames, process labels in Multiprotocol Label Switching (MPLS) or pseudo wire emulationedge-to-edge (PWE3) packets, perform quality of service (QoS) processing such as traffic classification andcommitted access rate (CAR) restriction for Ethernet data frames, and process operation, administrationand maintenance (OAM) packets and protocol packets.
In the transmit direction: The GE/10GE signal processing unit works with the packet switching unit to process VLAN tags in
Ethernet data frames, process labels in MPLS or PWE3 packets, perform QoS processing such as trafficshaping and queue scheduling for Ethernet data frames, and process OAM packets and protocol packets.
After delimiting frames, adding preambles, and calculating CRC codes, the GE/10GE signal processingunit performs parallel/serial conversion and encoding and then transmits GE/10GE signals to the GE/10GEoptical port after performing electrical-to-optical (E/O) conversion.
SDH Line UnitThe SDH line unit performs the following functions: STM-1/STM-4/STM-16 signal receiving,serial/parallel conversion, clock signal extraction, data restoration, overhead processing, alarmmonitoring/reporting, signal inloops/outloops, MSP, and ALS functions.
Power Supply UnitThe power supply unit performs the following functions: Combines two -48 V/-60 V DC power supplies, and converts the supplied power into the
power supply required by the chips of the other units on the local board.
