DESIGN
Clasification of building
• Based on
• Number of telephone station required
• Size of incoming underground cables to
the building
• Total floor area
Categorized of building
• Category 1
• Category 2
• Category 3
Category 1
• Category 1
• >5 storeys and any building with total floor space exceeds 650 m2
• Size of underground cable exceeds 50 pairs
• Jointing chamber usually required outside the building to facilitate linkage of entry duct to the building
• Ie; jc9 for cabless <400 pr
• R2A for larger size of cable
Category 2

floor space less than 650 m2
• Size of underground cable less than 50
pairs

INTERNAL DESIGN
How to start telephone design
• Planning
1. Site visit for verification client’s property
2. Any existing telecommunication infrastructure
3. The nearest telecommunication manhole
4. Application to service provider i.e.; TM c/w survey plan and target date of completion.
5. Obtain client’s requirement.
• Design
1. Liaise for telecommunitaion space/room
i.e., mdf room,sdf room, telefony room
riser etc.
2. Plan for external infrastructure.
3. Design internal infrastructure i.e. under
floor trunking system, internal cabling
PABX
• Determine telephony equipment (key
phone/PABX) and size
• Design schematic diagram
• Send 3 sets to TM
site plan, location plan, key plan
internal infrastructure (layout plan of under floor
ducting, telephone rooms)
schematic diagram
external infrastructure layout
