transmission network for wireless sites. The detailed access sites are according to RFP, please

refer to Annex2 for detailed sites information.

Network route map of Access part :

Map 1-2 Planned Access Microwave network structure

There are totally 53 sites involved for the Access transmission including 6 Backbone sites (1

existing site BOR001), 17 planned Capacity sites, 15 BB Access sites and 15 existing sites. The

backbone sites are used as access point to the Backbone network. The existing sites are used

to connect access sites to existing network. According to the RFP, the capacities of access links

are from 8E1 to 32E1. HSB and SD are used for the link protection, According to design,

totally34 Hops microwave required.

2.2 HuaweisUnderstanding

Huawei fully understands the importance of MTNs Requirement. Our goal is to provide a

solution that not only meets these needs but also exceeds the expectations.

Regarding the MTN microwave RFQ, Huawei does believe that the following key requirements

need to be focused in the network solution.

2.2.1 Requirement 1 in Huaweis understanding

Backbone part is the main channel for service transmission, it requires high capacity even the

more stability and easy expansion for the future.


6/23



After deeply studying and considering about the real requirement of MTNs Backbone network,

Huawei separate the backbone network to two types:

Type 1:STM-4 backbone Link from Juba to Malakal to Rank, totally 32 sites, 31 hops microwave.

This link will aggregate other backbone and access microwave link server, carry the BTS/NodeB

service alone this link and make the carry Malakal and Bors BSC service to Juba. Considering

the high capacity and stability requirement, Huawei proposes NEC 5000S to construct this link.

NEC is huaweis cooperator in backbone microwave field, Huawei has richful experience in

delivery NECs microwave. Huawei already delivery more than 20 Hops microwave link in South

Sudan.

Type 2:75 E1 links. This link mainly aggregate the access microwave service and BTS/Node B

service along this link and connect to the new backbone microwave link or existing microwave

link. Considering more IP service access, Huawei propose RTN900 IP microwave to build this

link. Considering the performance and extension, Huwei proposal use Andrew dual-polarize

antenna. It is easy to double the transmission capacity without any affection to existing link

service.

2.2.2 Requirement 2 in Huaweis understanding

This solution involves the next-generation and field-proven RTN 900 IP radio solution,

world-class professional services, and U2000-based end-to-end network management. In addition,

Huawei provides global and local service support systems. Thus, Huawei is qualified to meet MTNs

requirements for high efficiency and to assist MTN in delivering effective and competitive solutions

to its end users.

3. Huawei Backbone Microwave Solution

Huawei proposes to use NEC5000S to construct the backbone link from Juba to Malakal to

Rank.

3.1 Technical Description for 5000S

NEC 5000S Radio Systems are compatible with the latest SDH standards and will also be enhanced to further SDH

standardization. They include Operation, Administration, Provisioning and Maintenance functions which cover

alarm/status monitoring, switchover control performance monitoring and orderwire.

As link system, NEC provides both 4 - 11GHz long-haul microwave radio. These furnish the transmission

capacity of STM-1.

NEC 5000S SDH microwave radio is designed to maintain the conventional Radio Frequency (RF)

allocation restriction by adopting the optimum modulation scheme, as mentioned below, that makes possible

smooth migration from existing radio system to SDH radio system.

28/29/29.65MHz spacing: 128QAM

40MHz spacing: 64QAM

NEC 5000S SDH microwave radio has following basic specifications:

Capacity : 155.52 Mbps per system

Configuration: N+1 (N: 1-9);

N+0 (N: 1-10);

1+1 Twin path;

1+1 HS

SD Constitution : IF Combined system (3D SD)

Mounting : 10 system in ETSI Rack including MUX

Even if the existing PDH radio fully utilizes the assignable frequencies in the band, NEC 5000S SDH radio

can be added to the opposite interleaved RF channels of the existing system. NEC 5000S field-proven fully

digital XPIC enables the hybrid transmission of PDH and SDH radio signals on a CO-channel dual-polarization

transmission basis. This means there are no adverse effects regarding the frequency arrangement of the

existing system.

This sheet should be modified based on actual conditions such as terrain data & profile map by

contract date.

3.3Frequency Plan

As per the information in the tender document and suggestion from Huawei, we prepared a

frequency plan. Please refer to MICROWAVE TRANSMISSION NETWORK PLANNING

PROPOSAL for detailed information.

4. Huawei IP Radio Solutions

Huawei would like to provide the IP Radio solutions to MTN backhaul and access network, they are:

4.1QoS Solution

The OptiX RTN 900 can provide Enhanced QoS solutions, which can help operators to simplify the

configuration and get bandwidth fully used.

There is some principle need to follow to get the best solutions.

Simple flow classification (Diffserv domain) is used as much as possible on the UNI side.

The PHB service class is not higher than EF

Some bandwidths are reserved on the NNI side for protocol/DCN packets..

High-priority services at the NNI port cannot occupy all bandwidth..

Service rate is not limited on the NNI side.

Configure shaping on the NNI side when the leased bandwidth is less than the port bandwidth.

Selection of scheduling algorithm

DS domain configuration in complex scenarios.

The following tips are for QOS planning for different QOS requirement

End-to-end guaranteed bandwidth required

The flow classification (simple flow classification or complex flow classification) is selected

based on packet priority classification method.

If simple flow classification is selected, configure the Diffserv domain according to the mapping

between packet priorities and PHB service classes. The mapping should be provided by the

wireless department.


9/23



If the transmission network includes a third-party network, ensure that the bandwidth provided

by the third-party network is not less than the sum of guaranteed bandwidth.

If the bandwidth provided by microwave chain/ring is less than the guaranteed bandwidth,

expand the microwave chain/ring.

.Bandwidth limit required

If the bandwidth of incoming services needs to be limited according to service type, set limit for

services that are classified by means of complex flow classification.

If the bandwidth of outgoing services needs to be limited according to service type, set limit for

services that are classified by means of complex flow classification.

If bandwidth needs to be limited based on PHB service class, set limit for port queues.

Rate limit for egress flow and rate limit for port queue should not be enabled at the same time.

Guaranteed minimum bandwidth for low-priority services

Set limit for the queue that has higher priority than the queue where the service requiring

guaranteed minimum bandwidth.

The following table lists the recommended values for 3GPP servicesand service forwarding priorities. 3G

services include two types of services, namely, R99 and HSPA. Voice services take the priority of EF, R99 (R4)

data and HSPA-RT services take the priority of AF, and HSPA-NRT services take the priority of BE.

Figure 4.7 Traffic CoS Configuration Policy

If the mapping between Diffserv domain values and PHB service classes provided by the wireless

department is the same as the default mapping on the RTN equipment (DS = 1), Cos does not need

to be configured for the RTN network.

If they are different, Cos needs to be configured for the RTN network. To be specific, change the DS

domain value provided by the wireless department to the default one on the RTN equipment for

incoming services. The intermediate nodes on the RTN network use the default CoS value. Then,

change the default value on the RTN equipment back to the DS domain value provided by the

wireless department for outgoing services.

Figure 4.8 Traffic Shaping Configuration Policy

Configure port shaping based on the bandwidth provided by the third-party network.

As transmission channels, microwave has poorer shaping capability than routers. Therefore, routers

are recommended to perform traffic shaping for downlink data services.


11/23



Note: Currently, traffic shaping is performed based on L2 rate limit (20-bytes frame interval and preambles

unaccounted for). Therefore, the actual egress port bandwidth is more than the present value after the

traffic shaping function is enabled.

4.3Synchronization Solution

As 2G/3G/LTE will co-existing for long time, that TDM and IP will face the similar situation. Huawei

recommended that:

At physical layer, TDM (E1/STM-1) and Sync Eth as well as MW air-interface clock can provide a very good

quality of Frequency synchronization, if there is no application of cross the third party network.

At packet layer, CES ACR, 1588ACR can provide the frequency synchronization cross the network.

At packet layer, if TDD of time/phase synchronization is required, that 1588v2 will be a better way to

provide time/phase synchronization, rather than provide GPS and Bits.

In case of its difficult to deploy 1588v2 solutions, and then GPS/Bits will be the final solutions. Following

Bits are recommended. (Optional quotation)

4.4DCN Solution

Huawei provide complete solution of DCN, which are suitable for all applications, OptiX RTN 900 provide

Out-Band DCN and In-Band DCN solutions.

For Out-band DCN:

Cascading NM ports through network cables

DCN packets are transmitted to the OptiX RTN 900 through the NM ports. In this case, you can use the

Huawei private protocol, IP protocol or OSI protocol

Establishing DCC channels by means of overhead bytes in microwave frames

DCC channels use the DCC bytes in SDH frames, PDH or Hybrid microwave frames as the channels for

communication between NEs. DCN packets are transmitted to the OptiX RTN 900 through the overhead bytes

in microwave frames.

For In-band DCN:

In the case of the OptiX RTN equipment, network management information is transmitted through

service channels.

Advantages: Features flexible deployment and requires no extra network equipment.

Disadvantages: Occupies bandwidths of service channels. The network monitoring is affected when

the RTN network is faulty.

It is recommended that you adopt inband DCN when the network is composed of the OptiX RTN

equipment only.

When the U2000 is used to manage NEs, the number of non-gateway NEs accessed through one

gateway NE cannot exceed 120.

In the case of hybrid networking of third-party equipment and the OptiX RTN equipment, the

third-party equipment must support the setting of a specific VLAN ID (the default value is 4094) for

DCN packets.


14/23



It is recommended that the DCN bandwidth at the ETH ports should be set to 2 Mbit/s for a GNE. In

other cases, the DCN bandwidth is set to 512 kbit/s by default, and a margin DCN bandwidth of 1.6

kbit/s is preserved for each NE.

To improve network reliability, use a ring topology for a DCN network, if possible. In this manner, route

protection is provided when required.

It is recommended that the number of neighbor nodes should not exceed 20; If the number of

neighbor nodes is more than 20, disable the OSPF protocol and adopt static routes.

We can specify DCN solutions by two main scenarios:

The unique characteristic of allowing any Interface Typeand any Transmission Modeon the very

same Hardware and Software Platformgives total freedomin choosing the best options and the optimal

timing for upgrading the Microwave Network to Ethernet Transport.

The outstanding set of transport features, in addition to the traditional features of Microwave Radios,

provides the ability to support Carrier-Grade E2E transportin a future-proof and efficientway.

In conclusion, the evolution path of Huawei RTN 900 Series Microwave Radio is in full accordance with

MTNs strategic goal of the migration to packet based backhauling. Huawei RTN 900 Packet MW solution

together with Huawei Full outdoor series of E-band and Traditional bands provide the most comprehensive

Packet Microwave portfolio while adding to an easy backhauling and further meeting the backhaul

requirements for the planned all outdoor IP NodeBs & SDR and LTE eras all outdoor Picoand Micro

eNodeBs.

6. Disclaimer

The network dimension is subject to the business requirement and traffic model required in the

tender and any other assumptions deemed as necessary by the Bidder. In case the condition of

dimension varies, the BOQ and price shall be adjusted accordingly.

6.1Frequency

If the tenderer has placed a purchase order or trial order, the tenderer should be responsible for obtaining

the correct frequency sub band. Only the acquisition of the correct sub band can ensure the fast delivery and

deployment. If the acquisition of the sub band is delayed, Huawei shall not be liable for any change in quotation

and project delivery within the original scope of work.

If the product has been sold but the tenderer is unable to obtain the corresponding frequencies from the

relevant management authority, frequency adjustment will be made based on the actual conditions. Extra

expenses incurred for frequency adjustment are borne by the tenderer.

6.2Network ArchitectureAt the network planning stage, the initial planning needs to be modified accordingly after a detailed LOS

survey. The bill of quotation (BoQ) of the digital radio system also needs to be modified so that it can agree

with the actual radio network planning scheme, the LOS survey, and the local geographical conditions. In

addition, the price and the delivery schedule need to be modified accordingly.

If the LOS survey is beyond the responsibility of Huawei, the extra expenditure incurred for frequency

adjustment should not be borne by Huawei. Buildings or natural structures between two sites should not be

considered as factors affecting the LOS availability. If the LOS survey shows that there is an obstacle on a

transmission link and there is no way of redirecting the signals on this link to surrounding wireless base stations,

the tenderer should consider using repeaters or other transmission media. The expenditure incurred herebyshould be borne by the tenderer.

6.3Quotation

If the system contains third-party equipment, the extra expenditure for the devices such as hubs and

routers in the data communication network (DCN) should not be included in the quotation unless requested by

the tenderer.
