TDM Microwave: PDH microwave is used for access; SDH microwave is used for convergence. Ethernet services are transmitted in the space through the EOS technology. It supports the fixed modulation scheme from QPSK to 128QAM, and features
small capacity.It is used in 2G and early stages of 3G networks.
Hybrid Microwave: Native TDM + Native Ethernet It supports the modulation scheme from QPSK to 256QAM and the AM function,
and features high bandwidth. It is used in scenarios where TDM and IP networks coexist at the initial stage of the
transition from 2G networks to 3G networks. At this stage, voice services are primary and data services are secondary among mobile services. Adding the packet switching capability to the original TDM microwave equipment is undoubtedly the preferred solution at the transition stage of the mobile transport network evolution. In this way, investment in original equipment can be protected and existing voice services can be transported.
Packet Radio: It is pure packet microwave. It supports the modulation scheme from QPSK to 256QAM and the AM function,
and features high bandwidth. It is used at the All-IP stage of 3G networks. The pure packet microwave is the
best choice for a carrier who needs to build a new mobile IP transport network.

Evolution of Microwave Transmission Network
When microwave transport networks evolve towards packet transport networks inevitably, it is
a most cost-effective solution for carriers to evolve microwave transport networks from
traditional TDM microwave networks to hybrid microwave networks, and then to pure packet
microwave networks. This solution combines strengths such as protecting investment in
existing networks, flexible upgrade, and compatibility. If carriers need to build new mobile IP
transport networks, the best choice is to use advanced pure packet microwave equipment to
transport future All IP services.

Radio Link Forms
The OptiX RTN 900 V1R2 provides the radio links of different forms by flexibly configuring
different IF boards and ODUs to meet the requirements of different microwave application
scenarios. Different radio link forms of OptiX RTN 900 V1R2 support different types of
microwaves. The radio link form of the TDM microwave supports the PDH microwave and
the SDH microwave. The radio link form of the Hybrid microwave support the Hybrid
microwave.
1. The PDH microwave refers to the microwave that transmits only the PDH services
(mainly, the E1 services). During the transmission, the PDH microwave does not change
the features of the PDH services.
2. The SDH microwave refers to the microwave that transmits SDH services. During the
transmission, the SDH microwave does not change the features of the SDH services.
3. The Hybrid microwave refers to the microwave that transmits native E1 services and
native Ethernet services in hybrid mode. The Hybrid microwave supports the AM
function. During the transmission, the Hybrid microwave does not change the features of
the E1 services and Ethernet services.

TDM Microwave
The PDH microwave refers to the microwave that transmits only the PDH services (mainly, the E1 services). During the transmission, the PDH microwave does not change the features of the PDH services. Unlike the conventional PDH microwave equipment, the RTN 900 V1R2 has a built-in MADM. The MADM grooms the E1 services to the microwave port for further transmission. Thus, the services can be groomed flexibly and seamless convergence between the optical network and the microwave network is achieved.
The SDH microwave refers to the microwave that transmits SDH services. During the transmission, the SDH microwave does not change the features of the SDH services.
Unlike the conventional SDH microwave equipment, the RTN 900 V1R2 has a built-in MADM. The MADM grooms services to the microwave port through cross-connections, maps the services into the STM-1-based microwave frames, and then transmits the STM-1-based microwave frames. Thus, the services can be groomed flexibly and seamless convergence between the optical network and the microwave network is achieved.

Hybrid Microwave
The Hybrid microwave refers to the microwave that transmits native E1 services and native
Ethernet services in hybrid mode. The Hybrid microwave supports the AM function. During the
transmission, the Hybrid microwave does not change the features of the E1 services and
Ethernet services.
The RTN 900 V1R2 has a built-in MADM and a packet processing platform. The MADM
transmits E1 services that are accessed locally or extracted from the SDH to the microwave
port. After processing the accessed Ethernet services in the unified manner, the packet
processing platform transmits the Ethernet services to the microwave port. The microwave port
maps the E1 services and the Ethernet services into Hybrid microwave frames and then
transmits the Hybrid microwave frames.
Copyright © 2006 Huawei Technologies Co., Ltd. All rights reserved. Page 16
Service Transmission Mode The Hybrid microwave defines different types of Hybrid microwave frames for different working
modes. The accessed E1 services and Ethernet services are multiplexed into the same Hybrid microwave frame, and then transmitted to the ODU through the IF interface after IF coding and modulation. The E1 services and the Ethernet services are transmitted to the remote end through the microwave after the up-conversion.
The features of the Hybrid microwave frame are as follows:① The frames with a fixed period are used for transmission. ② In the specific modulation mode or channel spacing, the length of Hybrid microwave frames
remains unchanged. ③ The E1 services in Hybrid microwave frames occupy a fixed bandwidth (when N E1 services are
transmitted, the bandwidth of N E1 services is occupied). Thus, the Hybrid microwave does not change the features of the E1 services during transmission.
④ In Hybrid microwave frames, the Ethernet services occupy the remaining bandwidth of the E1 services. The encapsulation adaptation processing of the Ethernet frames is performed, so the Hybrid microwave does not change the features of the Ethernet services during transmission.
The hybrid transmission of native E1 services and native Ethernet services in the Hybrid microwave is supported.

Modulation Modes The TDM microwave only supports fixed modulation. The Hybrid microwave supports fixed
modulation and adaptive modulation (AM). The fixed modulation refers to a modulation scheme wherein a modulation scheme is
adopted invariably when the radio link is running. When the fixed modulation is adopted, the modulation scheme can be configured through software. A modulation scheme can range from QPSK to 256QAM.
The AM is a technology through which the modulation scheme can be adjusted automatically according to the channel quality. When the AM is adopted, the lowest modulation mode (also called reference mode) and highest modulation scheme (also called nominal mode) can be configured through software.

AM Technology Through the AM technology, the Hybrid microwave uses a high-efficiency modulation scheme
when the channel is of better quality. Hence, more user services can be transmitted and thus the transmission efficiency and spectrum utilization are improved. When the quality of the channel is degraded, the Hybrid microwave uses the low-efficiency modulation scheme, in which only the services of a high priority are transmitted. Hence, the anti-interference capability of links is enhanced and availability of the links on which the high-priority services are transmitted is ensured.
E1 services are of the highest priority in the AM-based Hybrid microwave transmission. Ethernet services are classified into flows of different priorities based on the CoS technology. When the Hybrid microwave uses the lowest-efficiency modulation scheme, the equipment transmits E1 services only (if the service bandwidth is higher than the total bandwidth of the E1 services, the Ethernet services of a high priority can be transmitted). When the Hybrid microwave uses other modulation schemes, the increased bandwidth can be used to transmit Ethernet services. In this case, availability of the links on which the E1 services and Ethernet services of a high priority are transmitted can be ensured and the capacity for transmitting Ethernet services increases.

AM Implementation
Before switching
When the SNR value received at the receive end is lower than the threshold, the receive end transmits quality degradation indication signals to the AM engine.
The AM engine at the receive end places switching indication signals to the overheads of a Hybrid microwave frame. The switching indication signals are transmitted to the local end through the transmit path.
The IF unit at the transmit end processes IF signals, and transmits the switching indication signals of the AM to the AM engine.
The AM engine transmits the switching indication signals to the service signal processing unit and the IF signal modulation unit, indicating that the service signal processing unit and the IF signal modulation unit complete the switching of service frames and the change of modulation schemes after frame N.
After the modulation scheme changes, the bandwidth of E1 services does not change. The Ethernet services with higher priorities are multiplexed into microwave frames based on the QoS. Thus, the remaining bandwidth of the microwave frames is used to transmit the Ethernet services with lower priorities.
Due to the switching to the low modulation scheme, the bandwidth of the Ethernet services that are multiplexed into the multiplex unit becomes low, and the bandwidth of the Hybrid microwave frames also becomes low.

The AM technology can use the QPSK, 16QAM, 32QAM, 64QAM, 128QAM, and 256QAM modulation schemes.
The lowest modulation scheme (also called reference mode) and highest modulation scheme (also called nominal mode) can be configured.
When the modulation schemes of the AM are switched, the transmit frequency, receive frequency, and channel spacing do not change.
When the AM modulation scheme is switched, the step by step mode is adopted. When the AM switches the modulation scheme, the services with a low priority are discarded but no bit errors or
slips occur in the services with a high priority. The speed of switching the modulation scheme meets the requirement for no bit error in the case of 100 dB/s fast fading.

Features
The OptiX RTN 900 V100R002 is a new-generation hybrid/TDM MW
transmission product developed by Huawei on the basis of the universal
platform that integrates TDM, Hybrid, and Packet. This product supports
features such as AM, synchronous Ethernet, Ethernet ring, and air interface
LAG. Huawei is the only supplier that provides the MW transmission
product integrating TDM, Hybrid, and Packet in the industry.
Smooth evolution: The universal platform supports the smooth evolution of
TDM -> Hybrid -> Pure Packet.
Hybrid ring protection: Hybrid ring protection is implemented by jointly
using the E1 SNCP and Ethernet ring protection switching (ERPS). The E1
SNCP and ERPS are independent of each other.
XPIC: When the XPIC and CCDP technologies are used, the transmitter
transmits two electromagnetic waves whose polarization directions are
orthogonal to each other to the receiver over the same channel. The
receiver recovers the original two channels of signals after eliminating the
interference between the two electromagnetic waves through the XPIC
technology. In this manner, the transmission capacity is doubled.

VLAN Nesting (QinQ)
The existing 4K CVLAN tags are insufficient for service planning. VLAN IDs are conflicted between convergence services and between
the services traversing a third-party network. The transmission department of the carrier is separate from the
wireless department, and it is difficult for the transmission department to work with the wireless department for VLAN planning.

E-Line ServiceThe E-Line service is a point-to-point service form on the topology. The equipment transmits the
packets or VLAN packets on a specified port on the user side to a port on the user side or network side
or to the QinQ link on the network side, thus implementing point-to-point transparent transmission of
user data.
According to transmission modes, E-Line services are classified into the following types:
(1) UNI-UNI Ethernet service
(2) UNI-NNI Ethernet service carried on a port
(3) UNI-NNI Ethernet service carried on a QinQ link

E-LAN ServiceThe E-LAN service is a multipoint-to-multipoint service form on the topology. The equipment forwards packets or VLAN packets on a specified port from the user side to multiple ports or to a PW or QinQ link on the network side, thus implementing multipoint-to-multipoint transparent transmission of user data. On the network side, the Ethernet services can be transmitted on a port or QinQ link. The QinQ link bearer means that an S-VLAN tag of the transport network is added to packets with the C-VLAN tag on the network of the user side, and thus the packets are labeled with two VLAN tags when traversing the transport network. This provides a simple L2VPN tunnel for users. With regard to the services carried on a QinQ link, the QoS can be ensured by configuring the QinQ policy.

MSTP The Multiple Spanning Tree Protocol (MSTP) is adopted for network loops. MSTP adopts an
algorithm to prune a looped network to a tree network without loops, thus preventing the increase
and infinite loop of packets on the looped network.

Ethernet ring protection switching (ERPS) is applicable to ring physical networks. The ERPS protects the E-LAN services between various nodes on the ring. After a ring network adopts Ethernet ring protection, normally, the owner node blocks the port on one side on the ring to transmit services on the port of the other side, thus preventing service loops. When a link or an NE on the ring is faulty, the owner node unblocks its upstream port to transmit services on the faulty link or NE, thus implementing ring network protection.
Values of the ERPS
The RPL owner prevents services from entering the RPL.
Ring Protection Link
1. Select the shortest path from the service channels between microwave stations on the ring.
2. Specify a ring protection link that projects any microwave link on the ring.
3. Any faulty microwave link on the ring can activate the ring protection link.
4. A link fault on the ring can be rectified through automatic or manual switching.

Ethernet OAMBackground
IP-based networks cater for the development trend. Different from SDH services, Ethernet services do
not have the operation, management, or
maintenance capabilities. There are no methods or tools to rapidly and easily
locate service link faults. There are requirements for detecting the faults and
performance of point-to-point Ethernet physical
links between two pieces of directly connected
equipment in the last mile.
