Diverse Optical Interfaces The 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.


Powerful Service Cross-Connect and Expansion Capabilities

ZXMP S330 supports service co-working in a variety of directions.

The higher-order cross-connect capability is 128 × 128 VC4; The lower-order cross-connect capability is 2016×2016 TU-12; The access capacity is 88 x 88 VC-4.

ZXMP S330 can also be used as an expansion subrack of the ZXMP S390, ZXMP S380, or ZXMP S385.


Perfect Equipment and Network Protection Capabilities Equipment protections

The key boards in the system are under the 1+1 redundancy protection, such as clock boards (SC) and CSB boards.

The service boards are under the 1:N (N≤5) redundancy protection.

ZXMP S330 adopts the dual power supply system. Each functional board is fed in the distributed power supply mode. This eliminates the power supply influence of one board upon another, and greatly reduces the impact of board hot-plug in the system.


Perfect Equipment and Network Protection Capabilities Network protections

MS chain protection; 2-fiber unidirectional/bidirectional path protection ring; 2-fiber bidirectional MS protection ring with or without extra

traffic; STM-4/16 4-fiber bidirectional MS protection ring; Dual Node Interconnection (DNI) protection; Subnet Connection Protection (SNCP).


Reliable Timing and Synchronization Capability ZXMP S330 provides 4 external reference clock outputs and 4 external

reference clock inputs; The external reference clock interfaces are provided by the clock

interface (SCI-75 or SCI-120) board, which is independent of the SC board;

The system allows setting 8 clock sources at the same time. 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.


Highly Reliable and Easy for Maintenance and Upgrade

Online 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.

Highly Reliable and Easy for Maintenance and Upgrade

Routine 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.

ZXMP S330 supports two kinds of SCI boards: SCI-75 is a 75 Ω SCI board. It provides two channels of 2.048 Mbit/s and 2.048

MHz coaxial 75 Ω receiving/transmitting interfaces (led out via 8 coaxial connectors). The first channel of 2.048 Mbit/s output and that of 2.048 MHz output originate from the same clock source, while the second channel of 2.048 Mbit/s output and that of 2.048 MHz output originate from the same clock source.

SCI-120 is a 120 Ω SCI board. It provides two channels of 2.048 Mbit/s and 2.048 MHz 120 Ω RJ11l receiving/transmitting interfaces (led out via eight RJ11 connectors). The first channel of 2.048 Mbit/s output and that of 2.048 MHz output originate from the same clock source, while the second channel of 2.048 Mbit/s output and that of 2.048 MHz output originate from the same clock source.

SCI board working principle

At the external clock input side: SCI board sends the received 2.048 Mbit/s and 2.048

MHz clock signals to the motherboard, and the motherboard

sends the clock signals to SC board for processing.

At the external clock output side: through the motherboard, SCI board receives the

2.048 Mbit/s and 2.048 MHz clock signals processed by SC board, and

then sends the clock signals to external equipment.

SED 板 Supports 8 FE and 2 GE Ethernet interfaces at the user side, thus accesses 10 channels of Ethernet signal

(LAN signal). There are 2 GE interfaces and 2 FE optical interfaces on the panel of the SED board. Among them, the GE

interfaces support SFP optical or electrical interface module. As for the other 6 FE Ethernet interfaces, the physical electrical interfaces are provided by the EIFEx6 interface board and the physical optical interfaces are provided by the OIS1x6 interface board.

Supports 16 VCG (EOS) ports at the system side, each port has the system bandwidth up to 8 AUGs. These VCG ports support 16:1 convergence ratio and bidirectional throughput capacity is up to 1Gbit/s. Supports three kinds of virtual concatenation: VC-12-Xv, VC-3-Xv and VC-4-Xv. Among which, VC-12-Xv

and VC-3-Xv can be mapped into a same VC-4 virtual container. A virtual concatenation supported by the SED board can contain 504 VC-12s, 24 VC-3s or 8 VC-4s at most.

Each virtual concatenation group can bind 1-63 VC-12s, 1-24 VC-3s or 1-8 VC-4s. Uses a flexible VLAN processing mode, to configure the VLAN as per the service requirements, as well as

to add, strip or modify the VLAN. Supports identifying QinQ and uses the outmost label 802.1Q as VLAN label to perform the research and

learning, as well as isolate the service in the ring network. Supports the speed limitation based on port, VLAN ID or priority. Supports Jumbo frame of 1600 bytes. Supports LCAS and Spanning Tree Protocol (STP). Supports Trunk function at the port. Supports GFP encapsulation structure. Implements extracting/inserting path overhead.

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 (N≤5) protection is needed, EIFEx4 board works

with BIFE board to implement the protection. When 1:N (N≤5) 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 (N≤5) 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 (N≤5) 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 Example With 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.

AP1x4 board

AP1x4 board is the ATM processor board. Provides four 155 Mbit/s optical interfaces at the ATM side, and four

155 Mbit/s non-concatenated data flows at the system side. User can select one to four VC-4 channels to transmit ATM traffic. It can extract the line clock which can serve as the clock source for

equipment. Supports four ATM traffic types: Constant Bit Rate (CBR) traffic, real-

time Variable Bit Rate (rt-VBR) traffic, non real-time Variable Bit Rate (nrt-VBR) traffic, and Unspecified Bit Rate (UBR) traffic.

Supports VP/VC local exchange. Supports VP protection switching upon alarms such as VP-AIS,

LOS, LOF, OOF, LAIS, and LCD.

RSEB board Supports 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 blocks Ethernet 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.
