1 x STM-64optical signal

Figure 4-1 Principle block diagram of SL64 The STM-64 optical signal is accessed at the interface unit and sent to the SDH signal processing unit after data and clock signal extraction at data and clock recovery unit. The SDH signal processing unit implements frame search, section overhead (SOH) termination and insertion, overhead byte extraction, pointer justification and path overhead (POH) monitoring to the incoming signal and then sends it to overhead processing unit for further processing. After that, the signal is re-timed with the system clock, and then multiplexed into 622M data signal after cross-connect and finally sent to the cross-connect and timing unit. The timing unit extracts the clock signal at line side and receives system clock and frame header from the active and standby cross-connect boards. It also provides clock signal for other modules on the board. The control and communication unit mainly functions control, communication, and service configuration of the board. The power module provides all modules of the board with DC power supply with required voltage. The overhead processing unit extracts the overhead bytes from the two channels of overhead signals it receives, and sends the extracted bytes to SCC and its paired board through the overhead bus according to related sequence and clock requirements. In transmit direction, the overhead processing unit re-arranges the received overhead signals from SCC or its paired board and then inserts them into the SOH.

4.3.3 Interface

The optical interface of SL64 is LC.

4.3.4 Board Configuration

Before using SL64 for running service, parameters should be set for it through transmission network management system (NM). Configuration should be provided to the following bytes for the line board:

J1 J1 is the path trace byte.Successive transmission of the higher order access point identifier through J1 at the transmit end helps the receive end learn that its connection with the specified transmit end is in continuous connection status. When J1 mismatch is detected at receive end, the corresponding VC-4 path will generate HP-TIM alarm.

C2 C2 is the signal label byte, indicating the multiplexing structure of VC-4 frame and the payload property. It is required that the C2 bytes transmitted match those received. Once mismatch is detected, the corresponding VC-4 path will generate HP-SLM alarm and insert all “1”s into the C4 in downstream stations.

Figure 4-8 Principle block diagram of TSB8 The interface unit of SEP1 is EU08 or OU08, which accesses 8 × STM-1 electrical/optical signals and sends them to SDH signal processing unit after data and clock signal extraction at data and clock recovery unit. The SDH signal processing unit implements frame search, SOH termination and insertion, overhead byte extraction, pointer justification and POH monitoring to the incoming signals and then sends them to overhead processing unit for further processing. After that, the signals are re-timed with the system clock, and then multiplexed into 622M data signals after cross-connect and finally sent to the cross-connect and timing unit. The timing unit extracts the clock signal at line side and receives system clock and frame header from the active and standby cross-connect boards. It also provides clock signal for other modules on the board. The control and communication unit mainly functions control, communication and service configuration of the board. The power module provides all modules of the board with DC power supply with required voltage. The overhead processing unit extracts the overhead bytes from the two channels of overhead signals it receives, and sends the extracted bytes to SCC and its paired board through the overhead bus according to related sequence and clock requirements. In transmit direction, the overhead processing unit re-arranges the received overhead signals from SCC or its paired board and then inserts them into the SOH. TSB8 enables TPS of SEP1. The signal selector of the TSB8 selects one out of the three groups of received signals from the three working SEP1s and sends them to the protection SEP1. The allocation drive allocates the signals from the protection SEP1 to the three working SEP1s.

Note: TPS is a scheme at device level. When the working board fails, the accessed signal will be protected by being bridged to the protection board. In this way, triggering of more complex protection at network level such as MSP and SNCP can be avoided, improving the equipment reliability.


Before using SEP1 for running service, parameters should be set for it through NM. Configuration should be provided to the following bytes for the line board:

J1 is the path trace byte.Successive transmission of the higher order access point identifier through J1 at the transmit end helps the receive end learn that its connection with the specified transmit end is in continuous connection status. When J1 mismatch is detected at receive end, the corresponding VC-4 path will generate HP-TIM alarm.

In receive direction: The interface processing module accesses the 1000BASE-SX/LX signals from external Ethernet equipments such as Ethernet switch and router and performs decoding and serial/parallel conversion to the signals. Then, the signals are sent to the service processing module for frame delimitation, preamble field code stripping, cyclic redundancy code (CRC) termination and Ethernet performance statistics. And flow classification is performed according to the service type and configuration requirement (message formats MPLS, L2 MPLS VPN and Ethernet/VLAN are supported), and Tunnel and VC double labels are added according to the service for mapping and transfer. At the encapsulation module, the HDLC, LAPS or GFP encapsulation is performed to the Ethernet frame. After that, the services are mapped into VC-3 or VC-12 at the mapping module and then sent to the cross-connect unit.

In transmit direction: The VC-3 or VC-12 signals from the cross-connect unit are demapped and sent to the encapsulation module for decapsulation. The service processing module determines the route according to the level of the equipment, and performs flow classification according to the service type and configuration requirement. Also, frame delimitation, adding preamble field code, CRC calculation and performance statistics are performed by the service processing module.Finally, the signals are sent out from the Ethernet interface after serial/parallel conversion and encoding at interface processing module.

Control and communication module The control and communication unit mainly functions control, communication and service configuration of the board.

In receive direction: The interface processing module accesses the 10/100BASE-TX signals from external Ethernet equipments such as Ethernet switch and router and performs decoding and serial/parallel conversion to the signals. Then, the signals are sent to the service processing module for frame delimitation, preamble field code stripping, cyclic redundancy code (CRC) termination and Ethernet performance statistics. And flow classification is performed according to the service type and configuration requirement (message formats MPLS, L2 MPLS VPN and Ethernet/VLAN are supported), and Tunnel and VC double labels are added according to the service for mapping and transfer. At the encapsulation module, the HDLC, LAPS or GFP encapsulation is performed to the Ethernet frame. After that, the services are mapped into VC-3 or VC-12 at the mapping module and then sent to the cross-connect unit.

In transmit direction: The VC-3 or VC-12 signals from the cross-connect and timing unit are demapped and sent to the encapsulation module for decapsulation. The service processing module determines the route according to the level of the equipment, and performs flow classification according to the service type and configuration requirement. Also, frame delimitation, adding preamble field code, CRC calculation and performance statistics are performed by the service processing module.Finally, the signals are sent out from

4.14 DCU

DCU is the dispersion compensation board. DCU can compensate the optical signal dispersion accumulated during fiber transmission in the 10Gbit/s system. It compresses the optical signal and works with the booster amplifier to achieve long distance optical transmission.Figure 4-26 shows the position of DCU in the optical transmission system.

1. Functions

DCU uses chirp grating to compensate the optical dispersion and compress the pulse signal for signal recovery.

Being a full-fiber and passive component, the plug-and-play chirp grating features powerful compensation capability and small volume. Batch production can be applied for it due to its easy making method and low cost.

When the transmission distance exceeds 80km, DCU can make dispersion compensation to two channels of optical signals at most simultaneously, with the compensation being 1020ps/nm (for dispersion generated on 60km G.652 fiber) or 1360ps/nm (for dispersion generated on 80km G.652 fiber), or the free combination of the two.

DCU can work with BA and PA for long distance optical transmission.

Figure 4-27 Principle block diagram of DCU After long distance transmission over optical fiber, the pulse of the 10Gbit/s signal becomes broadened as affected by the dispersion. Such seriously distorted signal can not be received by the optical receiver normally and no longer satisfies the transmission requirement.Send these optical signals into IN interface of the coupler, and then to the chirp grating through the single port of the coupler after an attenuation of 3dB. For spectrum components with different wavelengths, the chirp grating has different reflection positions. The reflection position for short wavelength components is at the inner part of the grating, which means a longer transport distance to the short wavelengths; while that for long wavelength components is at the external part of the grating, which means a shorter transport distance to the long wavelengths. Additionally, the delay of signals with different frequencies is not the same, as a result, the signals reflected back by the grating is “compressed”, thus achieving the compensation effect. The signal after compensation will return to the coupler and then be send out from the OUT interface after an attenuation of 3dB. These pulse-compressed optical signals can be received by receiver again and can be transmitted for a long distance over optical fiber.

None


Before the GXCS/EXCS is put into operation, configuration must be provided to the following parameters through NM.

1. Clock parameter

In common application where there is neither external clock input and output nor requirement for S1 byte for clock switching protection, the configuration for the synchronous timing unit is simple. Only the following configurations are needed:

Reference clock source Clock source stratum

When the reference clock source is the external BITS clock and the clock protection switching is required, the configuration is relatively complicated. The following configurations are required:

Reference clock source Clock source stratum External BITS type S1 byte Threshold of triggering clock switching protection

These configuration items in the NM operating system are explained below.

(1) Clock source stratum

It refers to the stratums of all available reference clock sources of the synchronous timing unit. In normal working state, the synchronous timing unit uses the clock source of the highest stratum as its reference clock. In case the clock source of higher stratum is lost, the one with lower stratum will be used instead, and so on and so forth, till the clock source of the lowest stratum is used ultimately. Generally the internal clock source is taken as the clock of the lowest stratum. So, when all the available clock sources are lost, the synchronous timing unit will eventually work in the free-run mode.

(2) Synchronous source

It is the current synchronous clock source configured for the synchronous timing unit. It must be one listed in the clock sources list. The clock of the highest class is usually


4-84

chosen as the synchronous source. Generally the synchronous timing unit will work with only the clock source stratum and the synchronous source configured.

(3) External input clock source mode

When an external clock source is selected as the synchronous source, the external clock source mode must be configured as 2048kbit/s or 2048kHz.

(4) Output external clock mode

When outputting external clock, the external clock source is also to be configured as 2048kbit/s or 2048kHz, and the match mode of the clock source needs configuring as 75Ω or 120Ω.

(5) Synchronization status byte S1

S1 byte is the synchronization status message (SSM) byte for transmitting the quality and use information of the clock source. When the mode of external clock source is 2048kbit/s and the automatic clock switching protection is required, S1 byte should be configured. With the information of S1, the synchronous timing unit can fulfill the automatic switching protection function for the clock source. The four high bits (b5 ~ b8) of S1 carries SSM. Table 4-30 shows the SSM coding. Table 4-30 SSM coding

S1 (b5-b8) S1 byte Description of SDH synchronization quality grades

1110 0x0E Reserved

1111 0x0F Not to be used as synchronization

S1 byte indicates the quality of clock synchronization quality. The less is the value, the higher quality is the clock signal. The clock stratum is set manually.

(6) Synchronous source threshold value

It is the clock quality threshold when the synchronous source is selected. In the case that the clock protection switching occurs, the system will check the reference clock sources that are above the quality threshold and select one with the highest stratum as the synchronous source of the NEs. When there is no qualified clock synchronous source, a usable clock source with the highest stratum at present will be selected.

(7) 2M phase-locked source selection

It is to select the phase-locked source of the 2048kHz clock signal output by the clock output port of the subrack. If the synchronous timing unit needs to provide external clock output, this item should be configured. That is, the clock source output by the external clock of the synchronous timing unit may be configured through software. This clock is independent of the synchronous source locked by this synchronous timing unit.

2. Principles

Technical details: There are four important databases on the SCC: mdb, drdb, fdb0 and fdb1. Mdb is in the dynamic random-access memory (RAM), saving the current databases.drdb is saved in flash RAM. When power failure occurs to NE, the databases will be recovered in the order of drdb→fdb0→fdb1. The drdb will be checked first for configuration data. If the configuration data are safe in drdb, they will be recovered to Mdb from drdb; If they are damaged, data will be recovered from fdb0 or fdb1, depending on which saves the latest data. If data in fdb0 are also damaged, fdb1 is used for data recovery. Therefore, it is important to back up fdb0 and fdb1 and compare the data in them.
