ACTUAL SITUATION
-
External Plant Network
Switching Network
Transmission network
1. General poor state of the external plant network
which needs a lot of management attention.
2. Unavailability of OMC in some networks
3. Insufficient practice of standard technical
management procedures.
4. A serious under investment in network management.
5. Little or no plans to develop a total integrated
Information Technology (IT) policy for management
of the External plant.

CHALLENGES AHEAD
1.
Management of networks by well established and
standard technical management procedures and
installation of TMN.
2.
Establishment of sub-regional management, operational
and maintenance centers.
3.
Maximum utilization of already established repair
centers in some countries on a sub-regional level.
4.
Monthly collection of network data and reports,
establishment of web sites with management, operations
and maintenance data by Regulatory Authority bodies.
CHALLENGES AHEAD (Continued)
• Formation of national technical committees participated by all

•
national operators and coordinated by the National
Administration
Establishment of statistical goals for telecommunication
service levels.
Complete overhaul, if possible, of external for good quality of
service for new technologies and services.
Establishment of procedures for utilization of network
management categories (i.e Configuration, Fault location and
repair, performance, security and accounting).
Development and usage of Information technology tools for
management of the external plant
