Diverse Optical InterfacesThe OL16 board of ZXMP S330 provides colorful optical interface, which facilitates ZXMP S330 to directly connect with the mux/demux unit of WDM equipment. In this way, the optical wavelength conversion unit can be omitted and the cost can be reduced. The OL1/4 board of ZXMP S330 supports single-fiber bidirectional application. This application can simultaneously receive and transmit optical signal in a single fiber, so as to save optical fibers. ZXMP S330 provides the optical module verification function, which detects whether the optical module in the equipment passes verification. If not, service will become abnormal, the EMS will report alarm. Only the optical module that has passed verification can work normally. The optical module verification function prevents service fault caused by the optical module that is not strictly tested.

The primary timing reference can come from any line (or tributary), 2 MHz interface, or 2Mbit interface;The phase-locked loop is controlled by software;The equipment supports the tributary re-timing for 2M service;The equipment supports the synchronous priority switching and the automatic switching based on SSM algorithm, which optimizes time synchronization distribution in the network, reduces difficulty in synchronization planning, prevents timing loops, and keeps the network synchronization in an optimal status. ZXMP S330 System Features

Highly Reliable and Easy for Maintenance and UpgradeOnline download and remote upgrade of the board software allow the upgrade to be intelligent, easy, and practical. During upgrade, the system will give warning for possible service interruption, so as to prevent misloading. Upgrade and re-configuration of the system are reversible, thus enhances the security of upgrade. The system can recover the original services in the case of upgrade failure, without affecting normal operation of services. ZXMP S330 System FeaturesZXMPZXMPZXMP

Highly Reliable and Easy for Maintenance and UpgradeRoutine maintenance allows quick fault locating to board. Critical boards that generate much heat are provided with the temperature detect function. The EMS, NCP software, and board software are independent of each other, so that their upgrades will not affect others. The EMS is independent of the board software version. This avoids frequent network-wide upgrade and reduces workload and difficulty of upgrade.When one software application is upgraded, there is no need to perform a network-wide software upgrade due to software mismatch. There is no need to perform upgrade of whole software set due to a single module fault. The system upgrades itself in a modular way to the least extent.

Connection relations in OL1/4 subsystemThe interface board and the service board are connected via STM-1/4 electrical signals. The service board is connected to the CS board via a bus. The service board converts the STM-1/4 data got from the interface board into a bus and then sends the data to the CS board. And the service board also obtains the bus data sent by the CS board, processes the data, and then sends the data to the interface board. The service board exchanges the DCC information on the line with the NCP board, and provides overhead bytes for the orderwire part of the NCP. The SC board provides the service board with the system clock and the system frame head. The service board divides the frequency of the received clock, and then sends it to the SC board as one of the reference clocks.

OIS1x4/OIS1x6 board OIS1x4 and OIS1x6 boards are the optical interface boards.Provide the service processing board with 4 or 6 STM-1 optical interfaces separately. Support the function of shutting down the laser.At the receive side, the board receives optical signal from the outside. Then it converts the optical signal into electrical signal and extracts the line signal. Finally, it sends the processed electrical signal to the service processing board via the motherboard for processing.At the transmit side, the board receives electrical signal sent by the service processing board via the motherboard. Then, it converts the electrical signal into optical signal. Finally, it transmits the optical signal to the outside.The board structures of OIS1x4 and OIS1x6 are similar with each other except for the interface number on the front of the boards. Take an OIS1x4 board as an example. The interfaces on the OIS1x4 board are Ethernet optical interfaces with LC/PC connectors, with the ascending numberings from top to bottom.The optical interfaces employ the SFP optical module. When working as Ethernet optical interfaces, they support the 100 M duplex work mode.

EIFEx4/ EIFEx6 board Provide 4/6 pairs of the Ethernet electrical interface.When 1:N (N5) protection is needed, EIFEx4 board works with BIFE board to implement the protection.When 1:N (N5) protection is not needed, EIFEx4 board only provides Ethernet electrical interfaces.EIFEx4 and EIFEx6 have the same working principle. At the receive side, the board receives Ethernet electrical signal from the outside, extracts the electrical signal, and then sends the signal to the Ethernet board via the motherboard for processing.At the transmit side, the board receives the signal sent by the Ethernet board via the motherboard, and then sends the signal to the outside.In the case of 1:N (N5) protection, EIFEx4 board determines whether to send the signal to the working board or to the protection board according to the control signal from the CSB board.

BIFE board BIFE board is the bridge interface board.Functions as a bridge between the protection SFEx6 board and the interface switching board (EIFEx4) corresponding to the faulty SFEx6 board. Used only when 1:N (N5) protection for FE electrical traffic is required.Inserted in the service interface board slot corresponding to the protection board.When fault occurs to a working SFEx6 board, according to the control signal sent by CS board, BIFE board bridges the signals sent/received by the EIFEx4 board which corresponds to the faulty SFEx6 board to the protection SFEx6 board for processing. BIFE board has no front panel and external interface.

EOS Subsystem Configuration ExampleWith this configuration, the system can process Ethernet electrical traffic by the SFEx6 board and Ethernet optical traffic by the SED board. It can provide one group of 1:3 protection for Ethernet electrical traffic. The SFEx6 board in slot 3 is the protection board; and the SFEx6 boards in slots 1, 2, 4 are working boards.

RSEB boardSupports the Q in Q identification; uses the outmost 802.1Q identifier as the VLAN identifier to isolate users; participates in learning, searching, and isolating traffic on the ring network.Supports different users by identifying them with VLAN ID. Every user can have multiple VLAN IDs, so that he can be completely isolated not only at local site but also between different sites, and thus satisfies the requirement of different user for data security.Every user can have traffic of different priorities (including class A, B, and C). And VLAN ID varies with the traffic class. The bandwidth and peak-value rate of traffic with a certain priority can be configured.Supports the fairness algorithm.Supports the topology discovery and protection function, and passthrough mode.Supports the configuration of EMS, query of alarm and performance, and other queries (including port running status and RPR ring topology relation diagram).The RPR ring bandwidth can be configure; supports VC4-xv and VC3-xv virtual concatenation; supports the bandwidth-adjustable RPR ring with granularity of VC-4.Supports the Bypass RPR MAC function: traffic is only switched by Ethernet and is not switched by RPR MAC.There are two kinds of RSEB board: RSEB-RPR and RSEB-EOS.RSEB-RPR board is the ordinary RSEB board. It provides the RPR networking function.RSEB-EOS board implements the pure EOS function with two GE interfaces (RPR system ports) by using Bypass RPR MAC switching.

RSEB board functional blocksEthernet traffic accesses to RPR network through four FE interfaces, two GE interfaces, or four EOS system ports. Traffic at these interfaces/ports is aggregated to the system GE interface (RPR system port) via the Ethernet switching unit, and then is sent to the RPR processing unit to implement all the functions of the RPR MAC adaptation layer.
