FIGURE 2 FUNCTION BLOCK DIAGRAM

ZXA10 C300 uses the backplane to connect all components. The control and switch card processes service signals, clock signals and control signals, then, sends them to the destination card. ZXA10 C300 has the following cards: �

Control and switch card

�

EPON service interface card

�

GPON service interface card

�

Ethernet interface card

�

TDM interface card (CES)

�

PTP Ethernet interface card

�

Power card

�

Common interface card

The control and switch card contains the system control module, data switch module, TDM switch module and clock module. The system contains clock bus, control bus and data bus. �

Clock bus: It provides clock to each card. The system provides two external clock input/output ports for clock synchronization.


9


�

Control bus: It provides communication channel for the control card and service cards, implementing system management and control.

�

Data bus: It implements service data interaction.

Service Flow This topic introduces ZXA10 C300 unicast data service flow, multicast service flow, TDM service flow and clock signal processing. Unicast Data Service

The unicast data service includes VoIP, VPN, VoD and HIS services. These services are processed as follows at OLT. �

Upstream i.

ONT data packets are mapped to GEM PORT according to UNI + VLAN + CoS, or, mapped to GEM port after MAC address learning.

ii. GEM PORT is mapped to different T-CONT according to service type. iii. With the use of DBA algorithm, OLT sends data packets to OLT PON card according to T-CONT parameters. iv. OLT PON card makes VLAN translate on data packets and configure VLAN work mode. If VLAN works in 1:1 mode, PON card checks whether it is required to restrict MAC address quantity. If MAC address quantity is not limited, PON card transfers data packets to the main control card. If the address quantity is limited, PON card performs address learning and then transfers data packets to the main control card. If VLAN works in N:1 mode, PON card performs address learning and checks address quantity. If the address quantity exceeds the limit, PON card discards data packets. If the address quantity does not exceed the limit, PON card transfers data packets to the main control card. v. The main control card checks VLAN mode. If VLAN works in 1:1 mode, the main control card finds the destination port from SVLAN + CVLAN list and transfers data packets to the destination uplink port. If VLAN works in N:1 mode, the main control card performs MAC address learning, then, transfers data packets to the uplink port of the uplink card. vi. The uplink card does not make any processing on service data. It only makes optical and electrical conversion, then, transmits data to the upper-layer network. �

Downstream i.

Data packets are transmitted to the main control card. The main control card checks VLAN work mode. If VLAN works in 1:1 mode, the main control card finds the destination PON card from SVLAN + CVLAN list and transfers data packets to the destination PON card.

10



If VLAN works in N:1 mode, the main control card queries MAC address and transfers data packets to the destination PON card. ii. PON card judges VLAN work mode. If VLAN works in 1:1 mode, PON card queries SVLAN + CVLAN list and makes VLAN translate, then, transmits data packets to the destination bridge port. After getting a GEM PORT at the destination bridge port, data packets are transmitted to the destination PON port. If VLAN works in N:1 mode, PON card gets the MAC address and VLAN value of data packets. PON card queries the MAC address. If it is successful, PON card sends data packets to the destination bridge port and makes VLAN translate. Then, it gets GEM PORT and transfers data packets to GPON interface. iii. Data packets are transmitted to ONT through ODN. ONT filters unnecessary data packets according to GEM PORT list. It queries MAC address or GEM PORT and UNI table to find the destination UNI interface. Then, it makes VLAN translate and sends data packets to UNI interface. Multicast Service

IGMP is used to control multicast service flow. Multicast data packets processing flow: Multicast data packets processing flow is as follows: 1. The uplink card transmits multicast data packets to the main control card transparently. 2. The main control card uses IGMP Snooping or IGMP Proxy protocol to process multicast data packets. IGMP adds/deletes multicast table items, or adds/deletes multicast port. Multicast data packets query the multicast table, then, copy data packets and transmit them to PON card. 3. The PON card also uses IGMP Snooping or IGMP Proxy protocol to process multicast data packets. IGMP adds/deletes multicast table items, or adds/deletes multicast port. Multicast data packets query the multicast table, then, copy data packets and transmit them to PON port. 4. Multicast data packets are transmitted to ONT in SCB mode. In GPON system, each PON port has a GEM PORT which is only in downstream direction. GEM PORT transmits multicast data packets from OLT to ONT. 5. ONT also uses IGMP Snooping or IGMP Proxy protocol to process multicast data packets. IGMP adds/deletes multicast table items. Multicast data packets query the multicast table, then, copy data packets and translate multicast VLAN to user VLAN. Finally, multicast data packets are transmitted to users from UNI interface. PTP downstream multicast service processing is the same as that on PON card. Multicast protocol packets processing flow: �

Upstream protocol packets If the multicast VLAN is an independent VLAN, protocol packets are transmitted through a separate GEM PORT. If the multicast VLAN shares a VLAN with other unicast data, protocol packets and unicast data are transmitted through the same GEM PORT.


11


�

Downstream protocol packets Downstream IGMP protocol packets are transmitted to all ONTs through GEM PORT.

TDM Service

TDM service includes service traffic processing and clock processing. Service traffic processing: �

Upstream i.

TDM data stream is encapsulated into data packets according to PWE3/MEF/ITU-T standard and added with a time stamp. Then, Data packets are encapsulated into Ethernet data packets and added with CVLAN. ONT maps data packets to relevant GEM PORT according to C-VLAN.

ii. Ethernet data packets are added with SVLAN at PON card and transmitted to the main control card in 1:1 mode. The main control card sends Ethernet data packets to TDM processing card according to SVLAN + CVLAN in 1:1 mode. TDM processing card resumes Ethernet data packets to TDM data stream and maps to E1/T1 interface or E1/T1 time slot of STM–1/4. Finally, TDM data stream is transmitted to TDM line interfa in E1/T1 or STM-1/4 format. �

Downstream i.

TDM data stream is sent to CES processing card from E1/T1 or STM-1/4 interface. CES card encapsulates TDM data stream into data packets according to PWE3/MEF/ITU-T standard and adds a time stamp. Then, CES card encapsulates data packets into Ethernet data packets and adds CVLAN + SVLAN, then, sends the data packets to the main card.

ii. The main control card sends Ethernet data packets to GPON card in 1:1 mode according to SVLAN + CVLAN. iii. GPON card bridges data packets to the relevant GEM PORT in 1:1 mode and sends to PON port after peeling off SVLAN. ONT finds CES resumption processing module according to CVLAN. CES resumption processing module resumes Ethernet data packets to TDM data stream and sends it to E1/T1/E3/T3 interface Clock processing: GPON system supports two TDM data stream clock resumption modes: �

Adaptive If the public reference clock does not exist, adaptive clock resumption can be used to synchronize clock. The disadvantage is that the clock is not so accurate or stable because of loss of packets or transmission delay.

�

Differential Differential clock resumption is to put the difference of the transmitting clock and public reference clock into the time stamp of data packets. Compared to adaptive clock resumption, differential clock resumption provides more stable and accurate clock. The disadvantage is that it needs a clock link between CES gateway devices.

12



Clock Signal Processing

Clock signal processing flow is as follows: 1. After converting the network clock to low-speed TTL clock signal, BITS/HZ clock interface sends the clock signal to the clock processing module on the main control card. 2. After making phase lock and frequency multiplication processing, the clock processing module sends the clock signal to the line card which needs the clock. 3. The clock processing module on the line card makes phase lock and frequency multiplication processing again. Then, it sends the clock signal to the line interface, ensuring that the line interface is synchronized with the clock distribution network. The clock module on Type A control and switch card can run in the free oscillation, holding and locking modes. ZXA10 C300 can extract the lock from BITS interface as clock source. Besides, it can extract clock from service interfaces, such as E1, T1, STM1 and STM-4.

Network Optimization

FTTH FTTH provides fiber to the home access service. In this scenario, central office equipment, OLT, is located in central equipment room or the equipment room in the residential area. It uplinks to the service network via N*GE and downlinks to ONU via splitters. The splitter is placed in a fiber cross-connect cabinet in the residential area’s equipment room or in the building. ONU is placed in the building or at the subscriber’s home. Different types of ONU provide different interfaces to support various access services. ONU is connected to a phone via POTS interface or connected to IAD and family gateway via FE interfaces, providing video, audio and data services such as Internet access, IPTV, CATV and VoIP. FTTH is suitable for new buildings, villas, old building with network equipment rebuilt. Figure 14 shows FTTH networking. FIGURE 14 FTTH NETWORKING

Chapter 5 Networking Application

FTTB FTTB provides fiber to the building access service. In this scenario, central office equipment, OLT, is located in central equipment room. It uplinks to the service network via N*GE and downlinks to ONU via splitters. The splitter is placed in a fiber cross-connect cabinet in the building or in the basement. Multi floors can share a splitter which is connected to each floor by using one-level or two-level splitting. ONU is placed in the fiber cross-connect cabinet in the building, the low-voltage shaft or mounted on the wall. Different types of ONU provide different interfaces to support various access services. ONU is connected to a phone via POTS interface or connected to IAD and family gateway via FE interfaces, providing video, audio and data services such as Internet access, IPTV and VoIP. Figure 15 shows FTTB networking. FIGURE 15 FTTB NETWORKING

FTTB is often used in the following scenarios: �

FTTB + xDSL Figure 16 shows FTTB + xDSL networking. FIGURE 16 FTTB + XDSL NETWORKING

Fiber terminal points are distributed in the building. MDU device is used to provide xDSL interface. The existing network resources can be fully used. ZTE provides medium-scale MDU such as ZXDSL 9806H. ZXDSL 9806H provides 96 ADSL/ADSL2+/SHDSL ports or 64 VDSL2 ports. ZXDSL 9806H is uplinked to OLT via PON port.

�

FTTB+LAN Figure 17 shows FTTB + LAN networking. FIGURE 17 FTTB + LAN NETWORKING

Fiber terminal points are distributed in the building. MDU device is used to provide Ethernet interface or VoIP interface. The distance between ONU and the end user cannot exceed 100 meters. ZTE provides medium-scale MDU such as ZXA10 F820. ZXA10 F820 provides 24 10 M/100 M Ethernet ports, 16 E1 ports or 32 POTS ports, meeting the requirements of various users.

FTTCab FTTCab provides fiber to the curb access service. In this scenario, central office equipment, OLT, is located in central equipment room or the equipment room in the residential area. It uplinks to the service network via N*GE and downlinks to ONU via splitters. MDU is placed in the fiber cross-connect cabinet at the curb. The upstream data is connected to WAN via GPON. The downstream data is connected to users via twisted pair cable. Each access device covers 800 to 1000 users. ADSL2+, VDSL2, SHDSL or LAN access modes are supported. For commercial or information districts which ask for more bandwidth, fiber connection is suggested. Figure 18 shows FTTCab networking.

FIGURE 18 FTTCAB NETWORKING

FTTO FTTO provides fiber to the office access service. In this scenario, central office equipment, OLT, is located in central equipment room. It uplinks to the service network via N*GE and downlinks to ONU via splitters. ONU is placed on the desk or mounted on the wall or placed outdoor. In FTTO scenario, ZXA10 C300 works together with ZXA10 MSAN in networking, supporting various access modes such as ADSL/ADSL2+, PBX, DDN and E1 dedicated line. The unified network management system NetNumen N31 is used for management. Figure 19 shows FTTO networking. FIGURE 19 FTTO NETWORKING


49


PTP Ethernet Optical Access By using wavelength division multiplexing technology, PTP technology transmits/receives data through one piece of fiber. Compared to 100 M/1000 M Ethernet interface which transmits/receives data through two pieces of fiber, PTP saves much fiber resources PTP Ethernet optical access is applicable to the following scenarios: �

Dedicated line In dedicated line scenario, each user use one dedicated fiber. PTP technology isolates users securely.

�

Backhaul transmission networking ZXA10 C300 supports networking by using PTP directly or using PTP loop.

�

Interconnection of different devices PTP supports interconnection of different devices.

Figure 20 shows PTP Ethernet optical access networking. FIGURE 20 PTP ETHERNET OPTICAL ACCESS NETWORKING

Video Monitoring Compare with general telecommunication services, video monitoring service requires more upstream bandwidth. With the advantages in bandwidth, QoS and security, GPON technology provides better video monitoring service. Figure 21 shows video monitoring networking based on PON technology.

FIGURE 21 VIDEO MONITORING NETWORKING

Wireless Communication Base Station Access In rebuilding 2G base station access node or in establishing 3G base station access networking, the traditional SDH network has many disadvantages. By using the IP and TDM core, ZTE GPON system is capable of providing better TDM and data services. Figure 22 shows wireless communication base station access networking. FIGURE 22 WIRELESS COMMUNICATION BASE STATION ACCESS NETWORKING

Network Optimization In the current networks, there are still some old transport systems in use, such as SDH and PDH, which only support narrowband ser-


51


vices. ZTE GPON system uses passive optical transmission, which can be used to rebuild the existing networks. In old networks, DSLAM devices are connected in chain. If one node is broken, the service of all devices cascaded with the node will be interrupted. In GPON networking, each DSLAM is connected to a splitter directly. The upstream bandwidth is increased. In addition, the network reliability and security is enhanced. Figure 23 shows network optimization networking. FIGURE 23 NETWORK OPTIMIZATION NETWORKING
