Board
Function
TN54NPO2/
Converts 64 channels of ODU0 signals, 32 channels of ODU1 signals, or
TN55NPO2/
8 channels of ODU2 signals into 8 channels of standard WDM wavelength
TN55NPO2E
OTU2 signals. Alternatively, the TN54NPO2/TN55NPO2/TN55NPO2E
converts 8 channels of ODU2e signals into 8 channels of OTU2e signals.
The TN54NPO2/TN55NPO2/TN55NPO2E supports hybrid transmission
of ODU0, ODU1, and ODU2/ODU2e signals. Further, the TN54NPO2/
TN55NPO2/TN55NPO2E receives 4 channels of OTU2/OTU2e signals
cross-connected from the ENQ2 by the backplane, multiplexes 12
channels of OTU2/OTU2e signals into one channel of optical signals, and
then outputs the optical signals. The TN54NPO2/TN55NPO2/
TN55NPO2E also performs the reverse process.
TN54PQ2
Performs 4 x 10G O/E integration when working with TN55NPO2.
TN54ENQ2
Converts thirty-two channels of ODU0 signals or sixteen channels of
ODU1 signals or four channels of ODU2/ODU2e signals from the
backplane into four OTU2/OTU2e signals. The TN54ENQ2 also performs
the reverse process. The TN54ENQ2 supports hybrid transmission of
ODU0, ODU1, and ODU2/ODU2e signals.
NOTE
The TN55NPO2/TN55NPO2E can process four wavelengths. After being equipped with the TN54PQ2
service processing board, it can process four more wavelengths.

System Control and Communication Board
The system control and communication unit is the control center for the equipment.
It helps the NM system to manage the boards of the equipment and enables the equipment to
communicate with each other.
The system control and communication units include: AUX board (system auxiliary interface
board) and SCC (system control and communication board).
The functions of the system control and communication unit are as follows:
l TN51AUX: Provides the system with various auxiliary interfaces and management
interfaces.
l TN51SCC/TN52SCC/TNK2SCC: Realizes the service grooming, configuration
management and alarm output of a subrack.
TN51SCC and TN52SCC are used in OptiX OSN 8800 T32 subrack. TNK2SCC is used in OptiX
OSN 8800 T64 subrack.
NOTE
An NE node of the OptiX OSN 8800 T32 and OptiX OSN 8800 T64 can consist of more than one subrack.
Usually, each OptiX OSN 8800 T32 subrack has two SCC boards in IU11 and IU28 for mutual backup.
The SCC is better installed in slot IU28. If there is a standby SCC, install the standby SCC in slot IU11.
8800 T64 subrack has two SCC boards in IU74 and IU85 for mutual backup. The SCC is better installed
in slot IU74. If there is a standby SCC, install the standby SCC in slot IU85. When subracks are cascaded
as master subrack and slave subrack, the SCC in the slave subrack collects intra-subrack alarms and
overhead. In addition to processing the intra-board overhead and alarms, the SCC in the master subrack
performs the overhead processing, alarm processing, and packet loading of all slave subracks. Then, it
issues the configuration to the slave subrack and connects to the NM system.
Clock Board
The clock board is used to provide the system clock and time to ensure the synchronization of
the clocks and time on the NEs.
77
The clock unit is as follows:
l STG: system clock board
The main function of the clock board is as follows:
l TN52STG/TNK2STG:
- Provides the intra-NE system clock and system frame. The service boards on the NE
use the system clock and frame header to synchronize the intra-NE services.
- Selects the time recovered from the service signals or the TOD port of the synchronous
timing interface board STI to synchronize the time of the entire system.
- Synchronize the time and clocks between the NEs.
TN52STG is used in OptiX OSN 8800 T32 subrack, and TNK2STG is used in OptiX OSN 8800
T64 subrack.
