NOTE
Area A and area B serve as mutual backups.
CAUTIONThe DC PDU should be maintained when the power supply is normal. Area A and area B, whichserve as mutual backups, cannot be maintained at the same time.
The DC PDU consists of the following areas.l Power supply input area: This area provides eight channels of power input terminals, which
are used to access eight channels of DC power supplies.l Power supply switch area: Eight switches, which are used to control the output of the power
supply, are present at the left and right sides of the DC PDU (four at each side).l Power supply output area: Eight groups of power terminals are present at the left and right
sides of the DC PDU (four groups at each side) . Eight groups of power terminals correspondto eight power switches at the left and right sides of the DC PDU (four at each side).
Functions and FeaturesFunctions and features of the DC PDU are listed as follows:
l The DC PDU supports the input and output of eight channels (four active and four standby)of stand-alone power supplies. The input DC voltage ranges from -38.4 V to -57.6 V or -48V to -72 V. The output current of each channel ranges from 0 A to 50 A.
l Dual OT terminals, which are used to input and output the power supply, are used. Thedual OT terminals can effectively prevent cables from rotating or being loosened.

l Area A and area B of the DC PDU serve as mutual hot backups.l If the OpitX PTN 1900 is installed in the same cabinet with the OpitX PTN 3900 , the DC
PDU supports the external power supply equal to or larger than 50 A and supports the fusecapacity of 50 A. If the OpitX PTN 1900 is installed separately, the DC PDU supports theexternal power supply equal to or larger than 30 A and supports the fuse capacity of 30A. If the backup is available, the switch can be removed or replaced when the power is on.For details, see OptiX PTN 1900 Quick Installation Guide.
l The DC PDU supports two grounding schemes, DC-C and DC-I, while the OptiX PTN1900 only supports the DC-I scheme.
NOTE
For the DC-C scheme, DC return conductors at multiple points can be connected to the common groundingnetwork. For the DC-I scheme, the DC return conductor at only one point can be connected to the commongrounding network. The short-circuit copper bar inside the DC PDU determines whether the DC-C or DC-I scheme is used. You can check whether the short-circuit copper bar is available by looking through thegrounding scheme indication hole on the front panel of the DC PDU. If the short-circuit copper bar isavailable, the grounding scheme is DC-C. Otherwise, the grounding scheme is DC-I. Figure 2-4 showsthe grounding scheme indication hole.
Internal ConnectionThe internal connection of the DC PDU is shown in Figure 2-5.

External ConnectionThe DC PDU can input or output eight channels of 30 A power supplies. The DC PDU canprovide power supplies to four OptiX PTN 1900 subracks at the same time, each of which canaccess two channels of power supplies. Two PIU boards are present in each subrack. Each PIUcan access one channel of power supply to provide power supply to the subrack. The two PIUboards use the 1+1 backup scheme. When one PIU fails, the other PIU can ensure the normalrunning of the equipment.
NOTE
If eight channels of power supplies cannot be accessed in the input area of the PDU, you can use a short-circuit copper connector to access four channels of power supplies, which are then divided into eightchannels of power supplies. Figure 2-6 shows the appearance of the short-circuit copper connector.
Figure 2-6 Appearance of the Short-circuit Copper Connector
The DC PDU can provide power supply to the independently installed OptiX PTN 1900 subrack,or provide power supplies to the OptiX PTN 3900 and OptiX PTN 1900 subracks installed inthe same cabinet.For the connection between the DC PDU and OptiX PTN 1900 subrack, seethe OptiX PTN 1900 Quick Installation Guide.

Service signals
In the Transmit DirectionThe MD1 first distributes packets, sent by the CXP, to different protocol processing modulesby the service type. For data processing module, decapsulation should be performed. The ingressqueue is then buffered and the egress queue is groomed by the service type. Then packets aresent to the link layer processing module. The line processing module performs encoding, de-jitter, pulse shaping and line driving for the services, which are finally sent to the interface board.
In the Receive DirectionThe interface board accesses E1 signals. The line processing module then performs impedancematch, signal equalization, electrical level conversion, clock data recovery, de-jitter anddecoding for the E1 signals. The link layer processing module and data processing moduleperform encapsulation and mapping of IMA E1, CES E1 and ML-PPP E1 services to PWE3. Inaddition, PW grooming is performed. Finally, the E1 services are sent to the CXP in the Ethernetpacket format.
Line Processing ModuleIn the receive channels, impedance match, signal equalization, electrical level conversion, clockdata recovery, de-jitter and decoding are performed to signals. In the transmit channels,encoding, de-jitter, pulse shaping and line driving are performed to signals.
Link Layer Processing ModuleThis module supports three protocol types, that is, IMA, CES and ML-PPP. The TDM circuitswitching, ATM cell switching can be performed on a uniform hardware platform.
Data Processing ModuleThis module performs encapsulation or decapsulation of IMA, CES and ML-PPP services to orfrom PWE3. In this way, data can be forwarded from the PPP to the MPLS. In addition, thismodule buffers the upstream and downstream packets, and grooms services.
Management ModuleThis module manages and controls the modules on the board.

In the Transmit DirectionThe CD1 first distributes signals, sent by the CXP, to different protocol processing modulesaccording to the service type. These chips then decapsulate these signals. The data processingmodule buffers the ingress queues and grooms the egress queues according to the service type.The data processing module then sends the packets to the link layer processing module. The linklayer processing module processes the packets according to different protocols, and then framesthe processed signals and sends the signals to the SDH processing module, which adds overheadto the signals and multiplexes the signals to STM-1 signals.
In the Receive DirectionThe SDH processing module first processes overhead of the channelized STM-1 signals that areaccessed, and demultiplexes the signals to E1 signals.

In the Transmit DirectionThe CXP sends packets to the data processing module, which demaps the PWE3 to ATM servicesand switches the ATM services. The data processing module then sends the ATM services tothe ATM lprocessing module. The ATM processing module processes the protocols for ATMservices, manages connections and resources, performs performance counting, grooms the trafficand controls the congestion for the ATM layer. The ATM processing module then sends theservices to the ATM access module. In the ATM access module, ATM services are mapped intoSDH services, which become STM-1 ATM optical signals after converted from electrical signalsto optical signals.
In the Receive DirectionFirst, 2 x STM-1 ATM optical signals are converted to electrical signals and sent to the ATMaccess module. This module extracts ATM cells from the SDH services and sends the ATM cellsto the ATM layer processing module. The ATM processing module then processes the protocols

Board reset button
The reset button is marked as RESET on the front panel of the board. The RESET button is usedfor cold reset of the TN72CXP.
Sub-Slot
The TN72CXP has two sub-slots, which are used to house one service sub-board respectively.
When only one TN72CXP is configured on the OptiX PTN 1900, select two service sub-boardsfor the two sub-slots as required. When two TN72CXP are configured on the OptiX PTN 1900,use service sub-boards by adhering to the following principles.
l Slot 1-1 and slot 2-1 form a TPS protection group. Slot 1-2 and slot 2-2 form another TPSprotection group. The two TPS protection groups are independent from each other.
l You can insert one service sub-board in either of the two sub-slots of each protection group.In this way, the protection group has no protection.
l You can insert two MD1 boards in the two sub-slots of each protection group. In this way,the service sub-boards are of 1:1 TPS protection.
l Do not insert different sub-boards in the two sub-slots of the each protection group.
l If slot 1-1 and slot 2-1 are not configured as a protection group, slot 1-1 and slot 2-1 canhouse different sub-boards.
NOTESlot x-y indicates the sub-slot y (service sub-board y) on the TN72CXP housed in slot x. For example, slot1-2 indicates the service sub-slot 2 (sub-board 2) on the TN72CXP housed in the first slot .

D Board Configuration Parameters
You can use the U2000 to configure each parameter of the processing board, interface board,cross-connect and system control board.
Parameters of the Processing BoardThe configurable parameters of the processing board are the J0, J1, J2, C2, V5, SDH interface,Ethernet interface, automatic laser shutdown (ALS) and spare timeslot recovery value.
l The J0 byte is continually transmitted to carry section access point identifiers, accordingto which the receive end verifies the constant connection to the intended transmit end. It isrecommended to set the J0 byte to "0".
l The J1 byte is the path tracing byte. The transmit end successively transmits the higherorder access point identifiers, according to which the receive end verifies the constantconnection to the intended transmit end. When detecting mismatch of the J1 bytes, thereceive end inserts the HP_TIM alarm in the corresponding path.
l The J2 byte is a VC-12 path tracing byte. The transmit end successively transmits the lowerorder access point identifiers based on the negotiation of the two ends. According to theseaccess point identifiers, the receive end verifies the constant connection to the intendedtransmit end in this path.
l The C2 byte is the signal label byte, which indicates the multiplexing structure of the VCframes and the payload property. The received C2 should be consistent with the transmittedC2. If the C2 bytes are mismatched, the local end inserts the HP_SLM alarm in thecorresponding VC-4 path.Table D-1 lists the mapping relation between the service type and setting of the C2.
