The processes which need attention while planning NMS System include:

1. Service Rollout process for RSPs
2. Service Rollout process for Network Operators
3. Fault Locating Solutions
4. Alarm Management and Health Check

2.5.9 Other Design Areas and Considerations

While Designing the Open Access Network following areas need special attention and agreement
with Customer/Network Operators:
1. VLAN Design: Broadband service types, user locations, and RSPs to which users belong are
identified by VLAN. In this manner, packets are classified and separately transmitted, and
QoS is performed.
2. IGP Routing Design: Depending on IGP section, may include OSPF or ISIS routing protocol.
3. BGP Routing Design: In the Open Access Network flexible aggregation/backbone layer
scenario, BGP is used to transmit service routing information on the aggregation and
backbone networks and between the Open Access Network and RSP network.
4. Multicast Routing: IPTV wholesale services are carried over multicast VPNs (MVPNs) on the
metro aggregation and backbone networks. MVPN routes need to be deployed on the
public network and VPNs.
5. MPLS Design: In the flexible open access network aggregation/backbone scenario, the
aggregation and backbone devices are deployed in the same MPLS domain. All wholesale
services except IPTV wholesale services are carried using MPLS on the aggregation and
backbone networks.
6. Voice, HSI and IPTV Service Bearer Design.
7. Enterprise Solutions: E‐Line, E‐LAN and Layer‐3 VPN Solution Design.

8. End‐to‐End Network Reliability Design.
9. QoS and Network Security Design.

2.6 Adaptation to Climate Change effect

2.6.1 Recommendation ITU‐T L.1500 describes a framework for information and communication
technologies (ICTs) and adaptation to the effects of climate change. This framework identifies and
defines the basis for development of the following Recommendations:
 Recommendation ITU‐T L.1501 on Best practices on how countries can utilize ICTs to adapt to
the effects of climate change ‐ on how ICTs can help countries to adapt to the effects of climate
change. It also provides a framework and a checklist for countries to integrate ICTs into their
national strategies for adaptation to climate change.
 Recommendation ITU‐T L.1502 on Adapting information and communication technology
infrastructure to the effects of climate change will provide a set of guidelines, requirements and
best practices to be referred to during operation, maintenance, upgrade and improvement of
existing infrastructure and when planning, designing and constructing ICT projects, goods and
services to adapt to the effects of climate change.
The adverse effects of climate change pose a threat to the development and sustainability of the
ICT sector and related sectors. To ensure sustainability of the ICT sector and other sectors it is
