To have a policy to install active tech for dark fiber at patch panel

# data[].attributes.body
1. Masih menggunakan Reactive Maintenance Concept
2. Perlu semak jika perlu adopt Time Based atau Condition Base

# data[].attributes.body
Teknologi fiber underground mengunakan ADSS (all-dielectric self support) menyukarkan kerja-kerja untuk tracing kerana tiada metal dalam binaan fiber tersebut

# data[].attributes.body
1. Kandungan SLA perlu meliputi availability of asset, project status dan sebagainya
2. ICT telah ada banyak servis yang diberikan pada pihak DN in term of communication for operation

# data[].attributes.body
staff ICT mempunyai access kepada premis TNB berdasarkan kepada keperluan kompetensi DN - OKST

# data[].attributes.body
1. Polisi baru perlu mengmbil kira keperluan comm network oleh aplikasi smart utility

# data[].attributes.body
abandoned cables are left as is

Akses kepada substation oleh Telco Service Provider

# data[].attributes.body
Jika TNB DN sub kepada syarikat luar untuk Service Provider di pencawang (contoh Allo pasang peralatan fiber di PE), isu adalah kunci kepada pencawang kerana ketika ini atas dasar keselamatan hanya staf TNB yng boleh pegang kunci.

1. Proses mendaftarkan aset comm dalam GIS perlu dikemaskini

# data[].attributes.body
1. tiada sebarang index digunakan utk menentukan keadaan aset
2. Pihak DN tiada proses menentukan tindakan bersesuaian terhadapa aset berdasarkan keadaan aset

# data[].attributes.body
asset & operational responsibilities

# data[].attributes.body
1. Pihak DN tiada guideline yang sesuai untuk membuat keputusan senggaraan bagi aset fiber

# data[].attributes.body
1. DN perlu proses bagi meluluskan sebarang keputusan untuk dispose

TTOM has no info on LILO , TTOM only know after RTU offline

# data[].attributes.body
While Fiber is the best in terms of reliability, however for green field (without fiber yet) it would cost high cost to start installing fiber. Therefore, TNB should strive to build its own wireless network which is faster & cheaper to deploy, and can be used by many parties

Fiber 11Kv Policy needs to be developed 

# data[].attributes.body
-TNB follows Telco Technology ( Jendela ) , this increases TNB cost
- TM DQ to Metro E migration

# data[].attributes.body
1. DN belum ada guideline untuk menentukan jenis comm network technology yang perlu diterima pakai

# data[].attributes.body
- TNB-ICT provide IP management (Example IP segment :03-SDE,09-Timur etc)
- Fixed IP application
- SCADA-IP Base RTU protocol ( IEC104/DNP.3-IP)

# data[].attributes.body
This is because TNB is using shared TELCO with Public
- Stadium JDT

# data[].attributes.body
- Sudden change of BTS causes RTU intermittent , TTOM needs to change antenna direction

# data[].attributes.body
Fiber trunk from telco for SCADA has no redundancy telco back end system
