The DCN between the U2000 and all the NEs is considered as the external DCN, and the DCN between the NEs is considered as the internal DCN. The OptiX RTN 910 supports several DCN solutions, including HWECC and IP DCN. HWECC is the commonest DCN solution. HWECC is a DCN solution provided by Huawei. In this solution, the NMS manages NEs using network management messages that are encapsulated in the HWECC protocol stack. Figure 5-1 shows how network management messages are transmitted in the HWECC solution. Ethernet link 18 OptiX RTN 910 Radio Transmission System Configuration Guide U2000 5 Configuring the Network Topology 5. A non-GNE refers to an NE whose application layer communicates with the NMS application layer by forwarding data through the GNE application layer. GNE Generally, a GNE is connected to the NMS through a local area network LAN or wide area network WAN. Its application layer can directly communicate with the NMS application layer. One set of NMS needs to be connected to one or more GNEs. ECC communication between the GNEs may create an oversized DCN. To prevent this, disable extended ECC for the GNEs. Non-GNE A non-GNE communicates with the GNE through the DCN channels between NEs. NE ID At the application layer of each DCN solution, an OptiX NE uses its NE ID as the NE address. Therefore, each NE must have a unique NE ID on the DCN and all these NE IDs must be planned in a unified manner. The NE ID has 24 bits. The most significant eight bits represent the subnet ID or the extended ID and the least significant 16 bits represent the basic ID. For example, if an NE ID is 0x090001, the subnet ID is 9 and the basic ID is 1. The IP address of the GNE must be planned as required by the external DCN. In this scenario, NE IP addresses must be on the same network segment. By default, NE IP addresses are on the 129. Therefore, each NE IP address on the DCN must be unique and all these NE IP addresses must be planned in a unified manner. By default which indicates that an NE IP address is never manually changed , this NE IP address is automatically changed to 0x81000000 + ID if the NE ID is changed. For example, if an NE Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Once an NE IP address is manually changed, the interlocking relationship between the NE ID and NE IP address no longer takes effect. It is recommended to configure the IP address of a GNE on a different network segment from the IP addresses of its non-GNEs. Table 5-1 provides the mappings between the physical boards and logical boards.

That is, SDH fibers indicate the connection relations between different SDH optical ports. That is, the radio links indicate the connection relations between different IF ports. That is, the extended ECC cables indicate the connection relations between the NEs. That is, the back-toback radio connections indicate the connection relations between the NEs. NOTE Fibers and cables are topological objects on the U2000. Hence, operations on the fibers or cables do not affect the normal running of the NEs. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. In this way, they can be displayed as a whole on the U2000, thus facilitating the NE management. The subnets are topological objects on the U2000. Hence, operations on the subnets do not affect the normal running of the NEs. In the case of a large number of topological objects, subnets that contain multiple NEs simplify the topology view on the U2000. Figure 5-2 provides the procedure for configuring the network topology. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Hence, you do not need to perform the corresponding operations in the initial configuration process. For the configuration procedure for an HWECC solution containing special requirements or another DCN solution, see related descriptions in the Feature Description. Table 5-2 Procedure for creating NEs Step Operation 1 Creating NEs on the U2000 Description A. To achieve SSL communication between the NMS and the gateway NE, Connection Mode needs to be set to Security SSL. The following parameters need to be set: l Set Search Mode to Search for NE. In the case of initial configuration, it is recommended that you set the 129. By default, NE User is root and Password is password. For SSL connection, set this parameter to Security SSL. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Set the parameters as follows: l Change New ID to be the NE ID specified during the planning of the DCN. Table 5-4 Procedure for configuring DCCs Step Operation Description 1 A. Set the parameters as follows: l In the case of the GNE, set IP Address and Subnet Mask according to the planning of the external DCN. If you need to set the gateway NE to allow for NMS access only in SSL connection mode, set Connection Mode to Security SSL. That is, if the NE ID is 0x090001, set IP Address to 129. Set Subnet Mask to 255. NOTE If the IP address of an NE is not changed manually, the IP address changes according to the NE ID and is always 0x81000000 + NE ID. In this case, the IP address of a non-GNE does not need to be changed manually. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. If inband DCN channels use the HWECC protocol, set Protocol Type to HWECC. If inband DCN channels use the IP protocol, set Protocol Type to IP. Set the parameters as follows: l In the case of the Ethernet ports and microwave ports that interconnect with the packet switching equipment, set Enabled Status to Enabled. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. It is recommended that the parameters adopt the default values. Set Standard NTP Server Identifier to IP and set Standard NTP Server to the IP address of the external NTP server. If the nonGNE needs to communicate with the GNE through the HWECC protocol, set Standard NTP Server Identifier to NE ID and set Standard NTP Server to the NE ID of the GNE. If the non-GNE needs to communicate with the GNE through the IP protocol, set Standard NTP Server Identifier to IP and set Standard NTP Server to the IP address of the GNE. Set the parameters according to the planning of the DST at the local area. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Set the parameters according to the identification authentication of the NTP. Table 5-6 Procedure for setting the performance monitoring status Step Operation Description 1 A. Figure 5-3 shows a TDM radio chain network configured according to the following requirements. Therefore, NE11 serves as a GNE and the other NEs are non-GNEs with an access to the U2000 through NE11. Therefore, the base station backhaul services converged from the TDM radio chain network are transmitted over the third-party SDH network. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Table 5-8 Connections of DCN links NE11 Link Port Description Link between NE11 and the third-party SDH network 8-SL1D-1 working unit l Configure the ports as a 1 +1 linear MSP group. In the HWECC solution, NE12 and NE13 communicate with each other through DCC channels in the SDH optical fibers and the other NEs communicate with each other through the DCC channels over microwave. If no fiber connections are set up between NE12 and NE13, NE12 and NE13 communicate with each other through the extended ECC that is enabled by default. Hence, the extended ECC function of NE11 needs to be disabled. The TDM radio chain and the third-party network are managed by the Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Therefore, the DCC channel needs to be disabled over the port on the N11 for connecting to the third-party network. Figure 5-4 Allocated IDs and IP addresses TDM radio chain network NMS 10. Hence, if the IP address of an NE not NE11 is not changed manually, the NE automatically changes the IP address to be the planned value after the NE ID is changed. The automatic synchronization period is one day. The daylight saving time DST scheme is not used at the local area.

When the AM technology is adopted, in the case of the same channel spacing, the microwave service bandwidth varies according to the modulation scheme; the higher the modulation efficiency, the higher the bandwidth of the transmitted services. This improves transmission efficiency and spectrum utilization of the system. This method improves anti-interference capabilities of the radio link, which helps ensure the link availability for higher-priority services. In Integrated IP radio mode, the equipment supports the AM technology. With configurable priorities for E1 services and packet services, the transmission is controlled based on the service bandwidth and QoS policies corresponding to the current modulation scheme. The highestpriority services are transmitted with precedence. NOTE In Integrated IP radio mode, when the equipment transmits STM-1 services and packet services at the same time, STM-1 services have highest priority and their transmission is ensured. When modulation scheme switching occurs, only the E1 services whose number is specified in the new modulation scheme can be transmitted and the excess E1 services are discarded. The services in different queues are transmitted to the microwave port after running the queue scheduling algorithm. When modulation scheme switching occurs, certain queues may be congested due to insufficient capacity at the air interface. As a result, certain services or all the services in these queues are discarded. Figure 6-1 shows the change in services brought by the AM technology. The orange part indicates E1 services. The blue part indicates packet services. The closer the service is to the outside of the cylinder in the figure, the lower the service priority. Under all channel conditions, the service capacity varies according to the modulation scheme. When the channel conditions are unfavorable during adverse weather conditions , lower-priority services are discarded. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. When the modulation scheme is downshifted, high-priority services will not be affected when low-priority services are discarded. CCDP, wherein two signals are transmitted over two orthogonal polarization waves, doubles the transmission capacity. XPIC cancels the cross-polarization interference between the two polarization waves. Microwave transmission can be classified into single-polarized transmission and CCDP transmission by polarization transmission mode. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. The capacity in CCDP transmission mode is twice the capacity in single-polarized transmission mode. Figure 6-2 Single-polarized transmission Figure 6-3 CCDP transmission The ideal situation of CCDP transmission is that no interference exists between the two orthogonal signals that operate at the same frequency, and then the receiver can easily recover the two signals. In actual engineering conditions, however, regardless of the orthogonality of the two signals, certain interference between the signals exists, due to cross-polarization discrimination XPD of the antenna and channel deterioration. To cancel the interference, the XPIC technology is used to receive and process the signals in the horizontal and vertical directions so that the original signals are recovered. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. The 1+1 protection configuration is classified into 1+1 HSB, 1+1 FD, and 1+1 SD. The opposite end selects one from the two received signals. With the 1+1 FD protection, the impact of the fading on signal transmission is reduced. The 1+1 FD protection also supports the 1+1 HSB protection. The equipment selects from the two received signals. With the 1+1 SD protection, the impact of the fading on signal transmission is reduced. The 1+1 SD protection also supports the 1+1 HSB protection. N+1 Protection Configuration The N+1 protection configuration indicates that the radio link has N working channels and one protection channel. The OptiX RTN 910 supports N+1 protection only in STM-1 radio and Integrated IP radio. The N+1 protection is implemented through the N+1 MSP similar to l:N linear MSP. XPIC Configuration The XPIC adopts both the horizontally polarized wave and the vertically polarized wave over one channel to transmit two channels of signals. The radio link capacity in XPIC configuration is double the radio link capacity in 1+0 configuration. The OptiX RTN 910 only supports the XPIC configuration for Integrated IP radio. Using PLA can effectively improve the bandwidth and reliability for transmitting Ethernet services over Integrated IP radio links. As shown in Figure 6-4, PLA allows all Ethernet transmission paths in several Integrated IP radio links connected to the same equipment to be aggregated as a PLA group. For MAC users, a PLA group works as a single link. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Different from air-interface LAG, PLA dynamically allocates Ethernet traffic based on the real— time Ethernet bandwidth over each member radio link to achieve almost the same Ethernet bandwidth utilization on member radio links. Except being free from impacts of the Ethernet frame type and packet length, the load sharing mechanism used by PLA even does not require the same Ethernet bandwidth on radio links involved. Moreover, this load sharing mechanism is also able to ensure almost the same Ethernet bandwidth utilization on member links when the Ethernet bandwidth changes differently on each member link. Figure 6-4 PLA Radio link 1 Native TDM Channel Ethernet Channel Physical Link Aggregation Ethernet Channel Native TDM Channel Radio link 2 PLA helps to improve Ethernet service bandwidth utilization and reliability in integrated IP radio mode when air-interface LAG does not apply for example, when member radio links provide different Ethernet bandwidths or the load sharing algorithm used by air-interface LAG cannot implement load balancing between member radio links. NOTE l The member links in a PLA group must be carried by the same type of IF board ISU2 or ISX2. The IF boards where the main and slave ports are located must be installed in two paired slots. Figure 6-5 provides the procedures for configuring radio links. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co.

Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Linear MSP Linear MSP applies to point-to-point physical networks. Linear MSP provides protection for the services between two multiplex section termination MST modules. That is, when a linear MSP switching occurs, the services are switched from the working section to the protection section. In the case of the OptiX RTN 910, linear MSP provides protection for TDM services that are transmitted over SDH fibers. Linear MSP is classified into 1+1 linear MSP and 1:N linear MSP. The protection channel does not transmit extra services. When the working channel becomes unavailable, services are switched to the protection channel for transmission. Figure 7-1 shows the application of 1+1 linear MSP. According to the revertive mode, 1+1 linear MSP is classified into dual-ended revertive, dual-ended nonrevertive, single-ended revertive, and single-ended non-revertive modes. The single-ended non-revertive mode is the most common linear MSP mode. Figure 7-1 1+1 linear MSP NE A Working channel NE B Protection channel Protection switching NE A Working channel NE B Protection channel Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. The working channels transmit normal services and the protection channel transmits extra services. When a working channel becomes unavailable, the services on this channel are switched to the protection channel for transmission. As a result, the extra services previously transmitted on this protection channel are interrupted. Figure 7-2 shows the application of the 1:N linear MSP. The 1:N linear MSP is available only in dual-ended revertive mode. Figure 7-2 1:N linear MSP NE A Normal service 1... Working channel 1 NE B Normal service1... Working channel N Normal service N Normal service N Protection channel Extra service Extra service Protection switching NE A Normal service 1... Normal service N Extra service Working channel 1 NE B Working channel N Protection channel Normal service1... Normal service N Extra service SNCP In the case of subnetwork connection protection SNCP , the protection subnetwork connection takes over when the working subnetwork connection fails or deteriorates. In the case of the OptiX RTN 910, SNCP provides protection for TDM services that are transmitted on STM-1 fiber ring networks, TDM radio ring networks, Hybrid radio ring networks, or hybrid ring networks that comprise optical network equipment and Hybrid radio equipment. The SNCP protection scheme, which requires one working subnetwork and one protection subnetwork, selects one service from the dually transmitted services. In the case of SNCP, the services are switched to the protection subnetwork for transmission when the working subnetwork connection fails or deteriorates. Figure 7-3 shows the application of SNCP. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. In the case of coexistence of the SNCP and the 1+1 protection or N+1 protection, you can set the hold-off time for SNCP so that the protection switching for the radio link can be performed first, thus preventing circular switchings. The timeslots for the TDM services on the IF board are closely related to the type of the radio services transmitted by the IF board and the radio capacity. TDM Radio When the IF board works in PDH radio mode and when the radio capacity is nxE1, the first to nth VC-12 timeslots on the IF board are available and correspond to first to nth E1s that are transmitted over microwave. For example, if the radio capacity is 4xE1, only the first to fourth VC-12 timeslots in VC4-1 on the IF board are available. If a cross-connection is configured between the E1 port of a service board and the second VC-12 in VC4-1 on the IF board, the E1 services that are accessed from the E1 port are sent to the second E1 timeslot that is transmitted over radio. When the IF board works in STM-1 radio mode, all the timeslots in VC4-1 on the IF board are available and correspond to the timeslots in the VC-4 that is transmitted on microwave. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. For example, if the E1 capacity is 75xE1, only the first to sixty-third VC-12 timeslots in VC4-1 and the first to twelfth VC-12 timeslots in VC4-2 on the IF board are available. If a cross-connection is configured between the E1 port of a service board and the second VC-12 in VC4-2 on the IF board, the E1 services that are accessed from the E1 port are sent to the sixty-fifth E1 timeslot that is transmitted over microwave. This scheme is the numbering scheme recommended by ITU-T G. The OptiX equipment can adopt this scheme when it interconnects with the equipment that adopts the interleaved scheme or when a specific timeslot numbering scheme is required.

Timeslot Allocation Diagram The timeslot allocation diagram provides significant references for configuring TDM services. Before planning TDM timeslots, you need to be familiar with the meanings shown in the timeslot allocation diagram.

The intermediate NEs each have two interface boards, which are located at the two sides of the vertical line under the NE icon. The interface boards may be IF boards or line boards. The interface board on the right side of the vertical line under an NE icon is connected to the interface board on the left side of the vertical line under its downstream NE icon. The timeslot area represents the VC-4 timeslot resources. For example, in the case of radio links, timeslots occupied by an STM-1 service are all in the first VC-4. In the timeslot allocation area, each straight line represents a service and the numeric above the straight line represents the timeslot occupied by this service. The board under a black dot indicates the board and corresponding ports on the board that are used for adding or dropping services. In the case of protection configuration for example, SNCP wherein the working service and protection service have different routes, you need to draw a continuous line to represent the working service and a dotted line to represent the protection service. TDM Timeslot Planning Scheme for Chain Networks On the backhaul network for a mobile BTS, the services are accessed from different nodes and then aggregated to the same node for transmission. In this case, allocate the timeslots on the chain radio network as follows: 1. Select the chain that contains the maximum of hops as the main chain. Then, divide the chain network into several sub-chains by considering the main chain as the reference. Consider the E1 channels or fiber connections that are used for transferring services between NEs as links. Repeat the previous step to configure the timeslots for the services on all the sub-chains. This timeslot allocation method ensures that only the numbers of the timeslots that the services on the nodes of the aggregation sub-chain occupy may change. The principles for obtaining the timeslot cross-connection configurations from the non-SNCP service timeslot allocation diagram are as follows: l The vertical line under the NE name is considered as the reference. The corresponding cross-connected timeslots are marked over the straight line. The corresponding cross-connected timeslots are marked over the straight line with one dot. The corresponding cross-connected timeslots on each board are marked over the straight line with an arrow on the side of this board. For details, see 7. TDM Timeslot Planning Scheme for Ring Networks On a backhaul network for a mobile BTS, the services are accessed from different nodes and then aggregated to the same node for transmission. Hence, you can perform the following operations to allocate the timeslots on the SNCP radio ring network: 1. Allocate the minimum VC-12 timeslot number to the service on the nearest NE. The number of the timeslot each service occupies does not change on the ring network. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. This timeslot allocation method ensures that only the timeslots that the services on the nodes of the aggregation sub-chain occupy change. The principles for obtaining the timeslot cross-connection configurations from the SNCP service timeslot allocation diagram are as follows: l The vertical line under the NE name is considered as the reference. The corresponding cross-connected timeslots are marked over the straight line. The corresponding cross-connected timeslots are marked over the straight line with one dot. For details, see 7.

E1 Priority needs to be modified according to the service planning information. NOTE When the radio link on which the AM function is enabled is configured with the E1 priority, note the following: l If the cross-connection is configured for a point-topoint service, the E1 priority is configured when the cross-connection is created. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. It is recommended that E1 Frame Format of both the local and opposite E1 ports be CRC-4 Multiframe. If E1 Frame Format is Unframe, the OptiX RTN 910 transparently transmits E1 frames and the local E1 port allows for interconnection with another E1 port whose E1 Frame Format is Double Frame or CRC-4 Multiframe. NOTE E1 Frame Format needs to be set to the same value at both ends of an E1 link. E1 ports integrated on the system control, switching, and timing board do not support this parameter. NOTE a: In the case of 1+1 protection configuration or 1+1 linear MSP, you need to configure the TDM service on the working channel only. In the case of N+1 protection configuration or 1:N linear MSP configuration, you need to configure TDM services on the working channels and the extra service if any on the protection channel.

Then, the packets are converged to the internal GE ports on the board, and then transmitted to the packet switching unit. The packet switching unit processes the packets of each port based on the port tags. In the transmit direction, the packet switching unit adds the port tags to the packets. Then, the packets are transmitted to the Ethernet switching unit through the internal GE ports on the board. The Ethernet switching unit transmits the packets to the ports based on the port tags. It transmits and receives MAC frames and does not have PHY-layer functions. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. The Ethernet services on the packet plane are transmitted to the EoPDH plane through PORT 10. The Ethernet services on the packet plane are transmitted to the FE port or VCTRUNK port on the EFP8 board through PORT 9. The Ethernet services on the packet plane are transmitted to the EoS plane through PORT 8. The Ethernet services on the packet plane are transmitted to the FE port, GE port, or VCTRUNK port on the EMS6 board through PORT 7.

Auto-Negotiation Function of FE Electrical Ports FE electrical ports may work in four common working modes: 10M half-duplex, 10M fullduplex, 100M half-duplex, and 100M full-duplex. If the working modes of the local FE electrical port and the opposite FE electrical port do not match, the two ports cannot communicate with each other. Auto-negotiation effectively resolves this problem. Auto-negotiation uses fast link pulses and normal link pulses to transfer negotiation information about the working mode; lastly, the working modes of the FE electrical ports match at both ends. Table 8-1 lists auto-negotiation rules for FE electrical ports. Table 8-1 Auto-negotiation rules for FE electrical ports when the local FE electrical port works in auto-negotiation mode Working Mode of the Opposite FE Electrical Port Auto-Negotiation Result Auto-negotiation 100M full-duplex 10M half-duplex 10M half-duplex 10M full-duplex 10M half-duplex 100M half-duplex 100M half-duplex 100M full-duplex 100M half-duplex NOTE As provided in Table 8-1, when the opposite FE electrical port works in 10M full-duplex or 100M full-duplex mode, auto-negotiation does not necessarily achieve full matching between the working modes of the FE electrical ports at both ends. As a result, some packets are lost. Therefore, when the opposite FE electrical port works in 10M full-duplex or 100M full-duplex mode, set the working mode of the local FE electrical port to 10M full-duplex or 100M full-duplex. When the FE electrical ports at both ends work in auto-negotiation mode, the equipment at both ends can negotiate flow control. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Auto-negotiation of GE electrical ports is similar to FE electrical port auto-negotiation. Table 8-2 lists auto-negotiation rules for GE electrical ports. Table 8-2 Auto-negotiation rules for GE electrical ports when the local GE electrical port works in auto-negotiation mode Working Mode of the Opposite GE Electrical Port Auto-Negotiation Result Auto-negotiation GE electrical port 1000M full-duplex Auto-negotiation FE electrical port 100M full-duplex 10M half-duplex 10M half-duplex 10M full-duplex 10M half-duplex 100M half-duplex 100M half-duplex 100M full-duplex 100M half-duplex 1000M full-duplex 1000M full-duplex NOTE As provided in Table 8-2, when the opposite GE electrical port works in 10M full-duplex or 100M full-duplex mode, auto-negotiation does not necessarily achieve full matching between the working modes of the GE electrical ports at both ends. As a result, some packets are lost. Therefore, when the opposite GE electrical port works in 10M full-duplex or 100M full-duplex mode, set the working mode of the local GE electrical port to 10M full-duplex or 100M full-duplex. When the GE electrical ports at both ends work in auto-negotiation mode, the equipment at both ends can negotiate flow control. Auto-Negotiation Function of GE Optical Ports GE optical ports support only 1000M full-duplex working mode. Auto-negotiation of GE optical ports is used only for negotiating flow control. This also causes buffer overflow and therefore some packets will be discarded. To reduce the number of packets to be discarded, take appropriate flow control measures. Half-duplex Ethernet uses a back-pressure mechanism to control flow. Full-duplex Ethernet uses PAUSE frames to control flow. Currently, half-duplex Ethernet is not widely applied; therefore, flow control implemented on the equipment is used for full-duplex Ethernet. Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Auto-Negotiation Flow Control When an Ethernet port works in auto-negotiation mode, use auto-negotiation flow control. The auto-negotiation flow control modes include the following: l Asymmetric PAUSE toward the link partner The port can transmit PAUSE frames in case of congestion but cannot process received PAUSE frames. NOTE On the NMS, the OptiX RTN 910 supports only two auto-negotiation flow control modes: Disabled mode and Enable Symmetric Flow Control symmetric PAUSE mode. Non-Auto-Negotiation Flow Control When an Ethernet port works in a fixed working mode, use non-auto-negotiation flow control. The non-auto-negotiation flow control modes include the following: l Send only The port can transmit PAUSE frames in case of congestion but cannot process received PAUSE frames. NOTE On the NMS, the OptiX RTN 910 supports only two non-auto-negotiation flow control modes: Disabled mode and Enable Symmetric Flow Control symmetric mode.

Pointto-point transmission does not involve service bandwidth sharing, service isolation, or service distinguishing; instead, Ethernet services are transparently transmitted between two service access points. Service Model Table 8-3 describes the point-to-point transparently transmitted E-Line service model. Table 8-3 Point-to-point transparently transmitted E-Line service model Service Model Traffic Flow Service Direction Encapsulation Type Description Model 1 PORT source UNI-UNI Null source The source port transparently transmits all the received Ethernet frames to the sink port. PORT sink Model 2 PORT source NOTE In service model 2, ports process the received Ethernet frames according to their TAG attributes. Therefore, service model 2 is not a real transparent transmission model and is not recommended. PORT sink Null sink UNI-UNI 802. The sink port processes the Ethernet frames based on its TAG attribute, and then exports the processed Ethernet frames.

Port 1 and port 2 transparently transmit Ethernet service 1 and Ethernet service 2 to port 3 and port 4, respectively. Port 3 and port 4 then transmit Ethernet service 1 and Ethernet service 2 to NE2. Service processing on NE2 is the same as on NE1. In service model 2, Ethernet service 1 and Ethernet service 2, which carry no VLAN IDs or carry unknown VLAN IDs, are accessed to NE1 through port 1 and port 2 respectively. Port 1 and Port 2 process the incoming packets based on their own TAG attributes. Then, Port 1 and Port 2 send Ethernet service 1 and Ethernet service 2 to Port 3 and Port 4 respectively. Port 3 and Port 4 process the incoming packets based on their own TAG attributes. Then, Port 3 and Port 4 send Ethernet service 1 and Ethernet service 2 to NE2. Service processing on NE2 is the same as on NE1. These E-Line services are called VLAN-based E-Line services. Service Model Table 8-4 shows the VLAN-based E-Line service model.

After the two Ethernet services are received at NE1 through port 1 and port 2 respectively, they share the same transmission channel at port 3. On NE1, port 1 and port 2 process the incoming packets based on their own TAG attributes; then, port 1 and port 2 send service 1 and service 2 to port 3. Port 3 processes all the outgoing packets based on its TAG attribute, and then sends service 1 and service 2 to NE2. Due to the different VLAN IDs, service 1 and service 2 can be transmitted through port 3 at the same time. NE2 processes service 1 and service 2 in the same manner as NE1.

The source port only receives the Ethernet frames that carry C-VLAN tags. After receiving the Ethernet frames, it adds the S-VLAN tag that corresponds to the QinQ link to the Ethernet frames and then transmits the Ethernet frames to the sink port to which the QinQ link is connected. The source port adds the S-VLAN tag that corresponds to the QinQ link to all the Ethernet frames that carry specific CVLAN tags and then transmits the Ethernet frames to the sink port to which the QinQ link is connected. If the source and sink QinQ links have different S-VLAN tags, S-VLAN tag swapping occurs. QinQ link sink QinQ sink NOTE a: Set Tag to Tag Aware.

On the mobile carrier network shown in Figure 8-11, the VLAN IDs that received BTS services carry are planned in a unified manner and are unique globally. The BTS services share the Ethernet service bandwidth on the Hybrid radio network NE1 to NE5 and are isolated from each other by means of VLAN IDs. The BTS services are aggregated at NE1 and then transmitted Issue 04 2013-11-30 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. Therefore, in this example, services on the Hybrid radio network of the mobile carrier network are configured as VLAN-based E-Line services.

As shown in Figure 8-12, the mobile carrier network need not sense whether the received BTS services carry any VLAN IDs. Services from each BTS are aggregated at NE1 and then transmitted through the regional backhaul network to the BSC. Therefore, in this example, the services on the Hybrid radio network NE1 to NE6 of the mobile carrier network are configured as IEEE 802. The Hybrid radio network checks the destination ports in the MAC address table according to the destination MAC addresses carried by the BTS services and then forwards BTS services to the ports. Therefore, isolate the ports that need not communicate with each other by adding the ports into a split horizon group.
