Specification for Voice and Data by Goran Andersson is licensed under a Creative Commons Attribution-ShareAlike 3.0 Unported License (http://creativecommons.org/licenses/by-sa/3.0/).

1.2. Application of this standards document. This document has been prepared as a technical guide for the deployment of IT infrastructure as used for the delivery of both Network Services and Telephone Services to University Staff and University Students. This is for application in the construction of new buildings.

1.3. Expected audience. As a reference document it is intended to provide guidance to the following:

• Installation contractors and technicians.

1.4. Management of revision levels. Where this document is used to control standards and specifications in a project, the version to be used is to be as:

• The version as agreed with ITS for use in that project.

or

• The version as specified in overarching documentation.

1.5. Hierarchy of standards documents.



2. Installation Standards. 2.1. External reticulation systems (Underground Conduits).

2.1.1. Exclusions from underground reticulation. Non-compliant services, as defined in standard S-009, are to be excluded from all Communications infrastructure and reticulation paths.

2.1.2. Aerial cabling. The use of aerial cabling is not permitted.

2.1.3. Cable pits. All underground pits are to be one of the following:

2.1.3.1. Pre-formed pits. All pre-formed pits for telecommunications are to be industry standard pits where the pit body is made from either plastic or concrete and the lid is made from concrete. The pit lid is to be either without marking or marked as “C” or “COMCABLE”.

Figure 1: Typical pre-formed pit.

2.1.3.2. Pits (Man-holes) constructed on site. All pits that are constructed on location are have a concrete bottom, which is a minimum of 50mm thick, brick-work sides and provided with a pre-cast concrete or metal lid. The pit lid is to be either without marking or marked with “T”, “C” or “COMCABLE”.



Figure 2: Cable pit which is constructed in situ.

2.1.3.3. Load ratings for pits. Load rating for pits in undeveloped areas and paths used solely for foot traffic. Pits used in these areas are to be fitted with pits rated at “Class A” or “Class B” as defined in AS-3996. Load rating for roads and vehicular paths. Pits used in these areas are to be fitted with pit-lids rated as “Class C” as defined in AS-3996.

2.1.3.5. Capacity of cable pits. The method used at the University of Wollongong to determine the appropriate size of cable pit for the size and number of conduits entering pit. The method is based on calculating what we have termed a pit access area from the length of the pit and the width of the pit multiplied together. The length, in metres and parts of a metre, is to be multiplied with the width, in metres and parts of a metre, to form a pit access area in square metres. The following tables are then to be applied to determine the number of conduits the pit can support.

Figure 3: Dimensions of pit to determine access area calculation.

Access area = Length x Width (all units in metres)

2.1.4. Underground conduits. The following standards are to apply to the provision of underground conduits.

2.1.4.1. Conduit size. The sizes and numbers of underground conduits are to provide 90% spare capacity for future expansion and the establishment of backbone runs may require further spare capacity. The minimum size underground conduit is 50mm in size.

2.1.4.2. Capacity of conduits. The following table showing the capacity of various conduit sizes for different size cables is to be used as a guide for cable installations.

2.1.4.3. Conduit colour. All conduits are to be coloured white in accordance with ACIF S009 standard.

2.1.4.4. Conduit construction. For general underground installation, conduits are to have a rating of “Medium Duty” as specified in AS-2053.2. For installation under roadways and other high-load circumstances, the conduits are to have a rating of “Heavy Duty” as specified in AS-2053.2. Where a different size conduit has been specified, or a different rating has been referred to, in the documentation for a specific project, the specifications mentioned in that project document, will override the specifications listed here.

2.1.4.5. Exposed external conduits. For external applications where a conduit is required to be in an exposed position such as would be the case when fixed to the side of a bridge, the exposed section of conduit is to be made from 100mm Dia. Galvanised steel pipe and have a minimum wall thickness of 3mm.

2.1.4.6. Installed depth of conduit runs. Conduits are to be inserted at a minimum depth of 400mm under pedestrian traffic areas and 600mm under roads, vehicular paths and undeveloped areas. Where easements are defined, conduits are to be located within easement and as defined for telecommunications and data services.

2.1.4.7. Exposed sections. Where conduit runs are exposed, PVC constructed pipes are not to be used and screwed metal pipes are to be used. The transition from PVC pipes to metal pipes is to be made at a cable pit.

2.1.4.8. Pull cords. All conduit runs are to be provided with a pull cord. Pull cords are to made from material that is immune from corrosion and rotting such as nylon or polyester.

2.1.4.9. Building entries. There must always be provision to prevent or minimise the chance of water flowing from conduit system into building at the building entry from the conduit system. This is to be implemented by making the external cabling pit 300mm lower than the conduit entry in the building.

Figure 4: Preferred approach to minimise chance of water ingress.

Where the external pit can not be made lower than the incoming conduit, The conduit is to be plugged at the up-hill end. For this we specify the use of a plug of expanding polystyrene foam. For a 100mm diameter conduit, the foam plug is not to extend more than 100mm into the conduit. For smaller conduits, the foam plug is not to extend further than 50mm into the conduit.

Figure 5: Alternate approach for preventing water ingress.

2.1.4.10. Ingress of water and drainage. Cable pits are to be installed completely level or slightly proud of surrounding ground level to minimise the ingress of water into pit. Every pit is to have a drainage hole, located in the bottom of pit.



2.1.4.11. Interfacing conduits with cabling pits. For cabling pits that are less than 500mm in width, conduits are to enter pit only at ends of pit. For large square and rectangular pits, conduits are allowed to enter pit directly from all directions.

Figure 6: Approved interfacing between conduits and cable pit.

2.2 Internal Reticulation Systems

2.2.1. Exclusions from internal reticulation systems. Non-compliant services, as defined in standard S-009, are to be excluded from all Communications infrastructure and reticulation paths.

2.2.2. Bulk reticulation – Horizontal cable tray. Cable tray is to be installed so that there is a minimum of 300mm general clearance above tray and so that there is no protrusion within that space which is nearer than 75mm above tray. Cables are to be installed on top of tray with fastenings no further apart than 1200mm.

Figure 7: Fixing of cable tray.

• Ad-hoc items such as ceiling support struts, air-conditioning ducts, etc. are not to be used to support cabling and associated tray.

• All cable tray is installed is to have adequate access to allow ongoing installation and removal of cabling.

2.2.3. Bulk reticulation – Vertical ladder and tray. Cable ladders and/or cable tray is the preferred method of reticulating cables over vertical drops and within cable risers. The size of the ladder/tray is to be such that all cabling can be directly secured to the tray or ladder. The ladder or tray should have is to be installed so that:



• There is to be a minimum of 300mm of general clearance in front of the tray during installation of cable.

• The ladder or tray is firmly secured and is to have a minimum of 20mm clearance from wall behind.

2.2.4. Final reticulation – Outlet cabling.

• The maximum allowable sag of catenary is 100mm .

• There is a minimum clearance of 50mm from attached cable and the suspended ceiling below.

• There is adequate access to allow on-going future installation and removal of cabling.

Figure 8: Installation of catenary cables.

2.2.4.2. Conduits through sealed areas. Conduit may be used to provide cable support over sections of reticulation where access can not be provided. Installation of conduits is to be undertaken with the following conditions:

• Minimum size of conduit is 50mm diameter.

• Conduit is to be PVC and to be White or Grey in colour.

• Access is to be provided at both ends of conduit.

2.2.4.3. Surface mounted conduit and duct. Installation of surface mounted of conduit and ducting is to be as follows:

• Conduit or duct is to be PVC and be White or Grey in colour.

• All conduit and cut to be securely fixed in place.

2.2.4.4. Wall cavity drops. Walls with accessible cavities can be used for vertical reticulation of cable with the following conditions:

• The width of the cavity is 100mm or greater.



• Cables are separated from all other services and cabling.

• Unsupported cavity drops are restricted to 3 metres.

2.2.5. Reticulation at Distributor Racks. Reticulation at racks in Distributor rooms is to be industry standard “Basket” type tray and is to be installed as follows:

• Tray is to have a minimum width of 400mm.

• Tray is to be installed at a height to provide a nominal clearance of 100mm to top of rack.

• Tray is to provide direct drop into back of cable-management verticals for outlet cabling.

• Tray is to provide direct drop to back of racks for reticulation of fibre-optic cables.

• Tray is to be joined to trunk reticulation used for building and/or floor.

2.2.6. Reticulation at Consolidation Frames. For reticulation to Consolidation Frames used at Building Distributors, industry standard perforated cable tray is to be used. Installation of tray is to be as follows:

• Minimum size of tray is to be 300mm wide.

• Tray is to be provided along both top and bottom of frame verticals.

• Tray is to be joined to basket tray used for reticulation over racks.

2.3. Standard Distributor rooms.

2.3.1. Provisioning required for Distributor rooms. Distributor rooms are to provide for the following items of infrastructure as required.

• Building Distributor racks as required.

• Floor Distributor racks as required.

• Krone consolidation frame as required.

2.3.2. Exlusions from Distributor rooms. It is required that all services involving liquids are intended to be excluded from reticulation in Distributor rooms. Where such exclusion is not possible, then the provision of drip-trays and splash-guards is required.

2.3.3. Access and clearances for equipment racks. A Distributor space needs to provide all the required clearances as noted below:



Figure 9: Layout and clearances for Building and Floor Distributor Racks.

• An access corridor of 600mm wide, as organised behind a row of racks is considered restricted. The maximum length of such a corridor, without additional access, is to be no more than 2.4m.

2.3.4. Access and clearances for Krone racks. A Krone frame is to have clearances no less than as indicated below:

Figure 10: Clearances required for Building Distributor Consolidation Frame.

2.3.5. Vertical clearances to cable reticulation. The major area of concern with vertical clearances is the clearance above the racks for cable reticulation. The required clearances are highlighted in the diagram below.



Figure 11: Side elevation showing clearances to rack and reticulation tray.

2.3.6. Surface finishes for Distributor Rooms. All ceilings are to be finished in a matt white painted finish. All walls are to be finished in a white or light grey matt painted finish. For closets and small rooms less than 6m2 floor area, the floors should be finished in a suitable gloss paint finish. In larger rooms such as Campus Distributors, the floor to be finished in a suitable vinyl covering.

2.3.7. Lighting requirements for Distributor Rooms. All spaces are to be provided with lighting adequate for service needs.

2.3.8. Cooling and ventilation requirements for Distributor Rooms. For maximum life of active equipment, Distributor rooms need to operate between 10-degrees and 25-degrees. This may require the provision of active cooling or active ventilation of the spaces. Where active A/C units are used, the issue of reliability should be addressed by the adoption of redundant A/C units or other mechanisms. To develop an appropriate size for cooling systems, ITS are able to supply indicative heat-load numbers for the equipment to be installed.

2.3.9. Confining noise from Distributor Rooms. The fan noise from equipment used in Distributor spaces is unsuitable for office and teaching environments. As such Distributor spaces need to be constructed so as to minimise the egress of noise and/or be suitably located to minimise the transmission of noise into such areas.

2.3.10. Security requirements for Distributor Rooms. All telecommunications spaces are to be secured with lockable doors. ITS has a preference for the use of active electronic access to Distributor rooms. As a fall-back option, ITS will consider the use of “ITS” keyed locks to these spaces. For rooms and spaces used only for cable reticulation, it is not considered necessary for electronic access to be used. Locks keyed to “ITS” are sufficient for this.



2.4. Equipment racks at Distributors.

2.4.1. General requirements for installing equipment racks. • Racks are to be installed with clearances as specified for Distributor rooms.

• Racks are to be installed side by side in rows.

• Racks are to be as specified in documented approved materials list or as dictated by ITS for specific projects.

• For combined Building and Floor Distributors, the Building Distributor rack is to be located to the Left of row.

• Maximum working height is limited to 1.8 metres of nominal height. On a 45RU rack, the top 5RU of rack space is not used.

2.4.2. Reticulation at Racks. Reticulation to racks is to be with overhead basket tray. We require the cable tray to sit across the top of the rack, from side to side, and have a nominal clearance of 100mm between the top of the rack and the bottom of the rack. The tray is to have a nominal width of 400mm and is to be set back by 220mm from front of rack to allow cables to drop into the top of the cable-management verticals as well as allowing fibre-optic cables to be dropped down the back of the racks.

Figure 12: Organising cabling from tray down to racks.

2.4.3. Provision of power at Distributor racks. The standard power outlet to Distributor Racks is a 20A power outlets, which are suspended from above at a nominal height of 400mm at the rear corner posts of the racks.



Figure 13: Standard method of providing power to racks.

• The numbers of outlets will be determined by the equipment to be installed in the racks.

• All 20A power outlets use sockets that fit angled flat pins and are compatible with 15A plugs.

An additional 10A double power outlet to be installed on wall at end of racks. This is to provide power for tools and diagnostic equipment.

2.4.4. Providing earth connections for racks. All equipment racks are required to be earthed to reduce risk to safety and to minimise chance of interference to signalling. The installation is to be as follows:

• The earth connection to link strip is to be installed in accordance with the AS3000 standard and is to be coloured Green/Yellow and a minimum size of 4mm2 CSA.

• The earth connection is to be provided on a “link strip” which is to be located within 1.5m distance from the specified location of equipment racks.

• There is to be only one Earth connection point in each Distributor room or server room.

• All equipment racks are to be individually connected to the Earth connection point using Green/Yellow cable of at least 2.5mm2 CSA. The “daisy chaining” of earth cable between racks is not permitted.

2.4.5. Identification of equipment racks. All racks are to be sequentially identified with a single letter starting at “A” through to “Z”. Sequence is to start at Left end of row of racks. Where there is more than a single row of racks, sequence for additional row is to continue from end of previous row.



2.4.6. Layout of Building Distributor rack. Layout of Building Distributor rack is as shown below.

Figure 14: Layout of Building Distributor Rack.

2.4.7 Layout and organisation of Floor Distributor rack. Floor Distributor racks are organised in pairs, the first rack is to be devoted to the provision of network ports and the second rack, of the pair, is to be devoted to outlet cabling. The layout of first rack, of a pair of Floor Distributor racks, is to be as follows:

Figure 15: Layout of Floor Distributor racks, first rack in pair.



Figure 16: Layout of Floor Distributor racks, second rack in pair.

2.4.8. Organising stand-alone Distributor Racks. There is provision for the operation of small Distributors which are organised as a single rack not enclosed within an enclosed room. These racks are to be organised as follows:

• Rack is to be fitted with back panel, side panels and front door.

• Selection of rack to be from selection as listed in approved products section.

• All Krone frames are to be provided with a "protective" earth.

• On "Profile" verticals, all termination blocks are to have earthing clips fitted

2.5.3. Organising cables at Krone frames. • There is to be 100mm of unsheathed cable slack left behind each module.



• As per standard practice with Krone frames, cable pairs are arranged from Left to Right on each 10-pair module and lowest module working up.

• For each cable on a frame, the entire cable is to appear on a sequential group of blocks on a single vertical. It is not permitted for a cable to be split between different areas on a vertical or across separate verticals.

• Cables of 100 pairs or more are to start at the bottom of a 10 module group and not part-way through a group of 10 modules.

2.5.4. Telecommunications reference conductors. A Telecommunications Reference Conductor (TRC) is to be installed at every Krone frame. Installation of TRC is to comply with requirements as detailed in Standards Document S-009. Specific University requirements for the TRC are as follows:

2.6.1.2. In-line joints in copper backbone cables. The use of in-line joints for copper backbone cables is purely at the discretion of the ITS Department. Any decision to deploy in-line joints for repair of cables or for new installation will be based on length of runs, critical nature of cable and provision allowed for joints in infrastructure.



2.6.2. Fibre-optic cables to Campus, Building and Floor Distributors.

2.6.2.1. Fibre-optic cable specifications and performance. • All cables installed in under-ground conduits are to be under-ground rated with Nylon sheath and

with “gel” moisture exclusion at the fibres.

• Only cables known as OM1 (62.5/125) and OS1 (9/125) are in use at the University. Other cables, such as OM2 and OM3 (50/125) are not to be used unless specifically directed to do so for specific applications.

2.6.2.4. In-line joints in Fibre-optic cables. The use of in-line joints for fibre-optic cables is purely at the discretion of the ITS Department. Any decision to deploy in-line joints for repair of cables or for new installation will be based on length of runs, critical nature of cable and provision allowed for joints in infrastructure.

2.6.2.5. Reticulation of Fibre-optic cables at Distributors. • The termination panel size is to be selected for best fit for the capacity of the cable or cables to be

terminated. In no instance is the capacity of the patch panel to have less capacity than the size of the cable or cables terminated in it. Cables are not allowed to be split across multiple patch panels.



• For cables with less than 24-fibres, it is expected that multiple cables will be terminated at a single 1RU panel. Using bigger panels to maximise the cable count at the panel is not permitted.

• Cable entry to patch panel is always to be from the back of the rack.

Figure 22: Reticulation of fibre cable into fibre patch panel.

• Cables are to be securely attached to the patch panel and are to rely solely on the panel for support. The cable can be tied to rack for some additional support but it has to be possible to separate the cable from the rack and move the patch panel.

• An allowance of slack is to be allowed for each fibre-optic cable. This allowance is to be between 4 metres and 6 metres.

2.6.3. Backbone copper cables to Floor Distributors. • Cables are to be implemented as one or more 25-pair cables. Cables are to be terminated at Krone

Consolidation frame at Building Distributor and racks at the Floor Distributor.

• At racks, cables are to be terminated on panels fitted with 24 8-way modular (RJ45) sockets. Sockets are to be considered as numbered 1 to 24 left to right.

• The cable and sockets are to be rated at voice-grade or better

• It is a requirement for the cable to be firmly attached to the patch-panel and is not rely on fixing to the rack for support.

level.

• Outlets for Wireless Network are expected to be at a nominal height of 2.4 metres above floor level, or higher. While it is common practise for these outlets to be located inside the ceiling cavity space, these outlets are not to be located higher than 600mm above the finished ceiling height. Outlet cabling terminated within the ceiling space, is permitted to be suspended from above so that the outlet can be located within the maximum of 600mm above finished ceiling.

For Wireless Network, the points are required to be within 1.5 metres of final Wireless Access-point location and with no intervening walls or other obstructions present.

• Sockets are to be oriented so that the connecting pins are located at the top of socket.



2.7.4. Reticulation of outlet cabling. • Outlet cabling is to be reticulated on cable tray and catenary reticulation with final reticulation to

outlet by wall-cavity drops or ducting.

• Outlet cabling is to go direct between Distributor rack and wall plate. Consolidation points or cable joints are not permitted.

2.7.5. Termination at Distributor. All outlet cabling is to be terminated at the rack-mounted cross connect of the Floor Distributor rack. Panels used at racks are all to be selected from approved materials list in section 8 of document.

• Dial-out lines are to be identified and labelled.

• All dial-out lines are to pass testing as detailed for voice-grade cabling.

Figure 24: Dial-out lines to end at socket or on terminal strip.



2.8. Special solutions.

2.8.1. Installation of Wireless Access-points.

2.8.1.1. Orientation of Access-points. The Wireless access-points used for general Wireless network access are designed for use in a horizontal orientation, facing down. The University is strict in ensuring that this orientation is maintained when installing the units. For special applications, the University may specify specific units that have different mounting requirements. For deployment of these units, the University will provide specific mounting requirements.

2.8.1.2. Mounting of Access-points. Wireless access-points are to be located on underside of ceiling, in visible location. For mounting on masonry and fixed plaster-board ceilings, The vendor provided mounting bracket is to be securely fastened and the access-point clipped into place. For mounting on tile array (grid) ceilings, the vendor provided ceiling grid clip is to be used to secure access-point into place. Where mounting on underside of ceiling is not practical, the use of right-angle wall-mount bracket is suggested.

2.8.13. Outlet requirements for Wireless. Each access-point is to be serviced by a double communications outlet. That is an outlet with two sockets, one for network connection and one to provide access to console port. At tile-array (grid) ceilings, the outlet is it be located up in the ceiling space. Where access-point is mounted on underside of concrete slab or on masonry surfaces, outlet is to be on industry standard mounting block located next to access-point. For access-points mounted on fixed plaster-board ceilings, outlet to be surface mounted next to access-point, on ceiling or as outlet up in ceiling space, if there is an access hatch [provided to allow servicing. Where outlets are located in ceiling space, the additional marking of outlets, as indicated in 2.8.2. is to be followed.

2.8.1.4. Securing Wireless Network Access-points. Wireless Network access points specifically are required to be secured. ITS standard keyed pad-locks are to be installed at the lock-down tab, supplied with the base-station mount.

2.8.2. Installation in ceiling spaces. This relates to the installation of CCTV cameras and other equipment that needs to be located within the ceiling space.

2.8.2.1. Mounting height. Outlets need to be located no higher than 600mm above the ceiling level. Where the slab above is higher, the outlets need to be suspended at this height.

2.8.2.2. Access to outlet. Where outlet is located above fixed ceiling, provision for access needs to be provided. We suggest the use of access-hatch to achieve this.



2.8.2.3. Additional labelling. Outlets located in ceiling spaces are to be provided with standard labelling. In addition to this an additional label fixed to the ceiling grid or access-hatch surround is also required.

Figure 25: Additional labelling on ceiling.

2.8.3. Service to remote systems enclosed in cabinets. This relates to installations where:

• The system is secured from general access, and

• the system is remote to the people that use and manage it.

2.8.3.1. Positioning and access to communications outlets. Provision of outlet cabling to user equipment to be as follows:

• Where the user equipment is located inside a secured space or cabinet, the Communications Outlet is to be mounted adjacent to user equipment.

• Where the user equipment is in a cabinet not secured away from general access and the cabinet will allow the mounting of a standard wall-plate or side-entry outlet, it is acceptable for the outlet to be located within the user cabinet.

• Where the Communications Outlet is not able to be mounted inside the user cabinet, but the Communications needs to be secured from general access, it is suggested that outlet, or both outlet and user equipment, be secured inside an enclosing box or cabinet.



Figure 26: Preferred installation of IT services to unmanned user equipment.

2.8.4. Installations which are external and remote to buildings. For equipment located more than 2 metres from the outside of a building, involves service over underground cable, or is mounted substantially above the roof-line of the building, all network services are to be provided over fibre-optic cable. This includes installations such as CCTV cameras, mounted on external poles, and other remote systems.

2.8.4.1. General conditions. The required equipment at the remote end is to be an Ethernet Media Converter operating at the 1310nm optical wavelength and capable of providing 100Mbps performance. Connection at the building end is to be at an agreed Building Distributor. Floor Distributors will not have space available for these connections. At the building end the connecting equipment is to be a network switch with fibre-optic ports or matching Media Converter as appropriate.



Figure 27: Standard for connecting external devices.

2.8.4.2. Constraints at remote equipment end. • The distance between the customer equipment and the media converter is to be less than 5 metres.

• The customer equipment and the media converter are to share a common Grounding connection.

2.8.4.3. Requirements at remote end. The mounting facilities, at the remote end need to provide for the termination of the fibre-optic cable, the mounting of media converter and the provision of power to media converter and user equipment. Attention needs to be made to provide required separation between cabling and services and to protect against ingress of moisture and other hazards.

2.9. Labelling and identification.

2.9.1. Identifying Communications spaces. All communications spaces are to be assigned a unique identifier for the building they service. All identifiers are to be in the form:

LN

Where each field in the identifier, ‘L’ and ‘N’, are defined as follows: L Is a field that identifies which floor level that the communications space is located on. The floor

level is that assigned by the university and is to be in the form “G” for ground floor, “1’ for first floor, “2” for second floor, etc.

N Is a sequential letter identifier for the space that is unique within each building level and is to be in the form “A”, “B”, “C”, etc.

An example of a space identifier would be “2D” which would be a space located on level 2 of a building and is the fourth space and hence the letter “D”.



2.9.2. Numbering convention for Building Backbone cables (internal cables). This numbering system is to be used for building backbone cables and other cables that are confined within a single building. Horizontal cabling (communications outlet cables) is excluded from this system. The cables will be marked using a numbering scheme as follows.

I-A-B-N

I Is a fixed designator “I” which indicates that this is an internal cable.

A Refers to room number of first end of cable.

B Refers to room number of second end of cable.

N Refers to sequential number of cable.

To maintain consistency in numbering, the A designation will be the lower of the two room numbers (A and B), with special note that building levels take precedent. For example, room G12 will come before room 123, and room 142 will come before room 42 (building levels take precedence). An example of the numbering convention would be I-GA-103-2 which would describe a cable from closet GA to room 103 and is the second cable run between those locations.

2.9.3. Numbering convention for Campus Backbone cables (external cables). This numbering system is to be used for campus backbone cables and other cables where the ends are in separate buildings. The cables will be marked using a numbering scheme as follows.

E-A-B-N

E Is a fixed designator “E” which indicates that this is an external cable.

A Refers to the building number at the first end of the cable.

B Refers to the building number of the second end of the cable.

N Refers to the sequential number of the cable.

To maintain consistency in numbering, the building with the lowest number of the two buildings will be used for the A designation (first field), the other higher numbered building will be used for the B designation (second field). An example of the numbering convention would be E-15-17-1 which would describe a cable from building 15 to building 17 and is the first cable between those locations.

2.9.4. Numbering convention for cables installed and operated under AARNet carrier license. This numbering system is to be used for backbone cables that are run external to the sites and are allowed only through coverage of the AARNet carrier license. To provide differentiation for this cabling, it has been decided to pre-fix the numbering with a “C”. As such, the cables will be marked using the following numbering scheme.

C-A-B-N

C Is a fixed designator “C” which indicates that this is a cable installed under the AARNet carrier license.



A This refers to the originating end of the cable. This is normally expected to be a building number under the University numbering scheme but it is understood that this may also be a splicing pit reference.

B This refers to the destination end of the cable. The destination end is expected to be referred to in one of three ways, it can be a reference to an external splicing pit, it can be a reference to the destination site, or it can be a building reference if the cable terminates within the building and the building number is unique.

N This is a numerical index to the cable and allows for there to be more than one cable with thgis source and destination.

As examples of this approach, consider C-17-CP020-1 which refers to a cable from building 17 to splice pit CP020. Another example would be C-15-CE-1 which refers to a cable from building 15 to Campus East and does not terminate in a building there.

2.9.5. Numbering convention for outlet cabling. The following convention is to be used at all times for allocating unique identifiers for telecommunications outlets.

CC.NNN

Where each field in the identifier is as follows: CC Is a field that identifies which closet the outlet is wired back to. This closet identifier is to be a

unique 2 character identifier as assigned in section 4.3.1.

NNN Is a unique numerical field that identifies the outlet by where it is terminated at the floor distributor wiring frame.

An example of an outlet identifier would be “L1.GA.103” which identifies an outlet on the first floor level, which is wired back to floor distributor on ground floor level and identified as “GA” and is connected at the location for outlet number 103 on the wiring frame.

2.9.6. Identification of specialised dial-out lines. Identification of dial-out lines. The specialised dial-out lines are to be sequentially numbered and to be identified with the tag “Line”.

The format of the identifier is:

Line-XX

Where:

XX is one or two digit sequential number.



2.9.7. Physical labelling of backbone cables. All trunk cables are to be numbered and clearly marked at both ends using one of the following techniques:

A. Metal tag with numbers stamped or engraved into the surface and secured with a metal band.

B. Adhesive label printed in black on white background which is further secured by use of UV resistant clear tape.

The label or tag is to be attached to the cable sheath at a distance between 20mm and 1500mm from end of sheath where it will be most visible.

2.9.8. Recording of copper cable at Krone frames. All cables terminated at Krone frames are to be written up in standard Kroner record sheets. Additional sheets are to be supplied as required. For new installations, a record book is to be provided a frame. It is responsibility of installer to ensure all cabling at Krone frame is written up.

2.9.9. Recording of fibre-optic cables at racks. All fibre-optic cables terminated at racks are to be written up in on ITS provided record sheets. It is responsibility of installer to ensure that cables are written up and that book of sheets is left at racks.

2.9.10. Labelling on fibre-optic patch panels. The termination enclosures and patch panels for fibre optic cables are to be each assigned with a unique sequential identifier of the form “A”, “B”, “C”, etc. Each panel is to be clearly marked with the assigned identifier. On the panel, the sequence of the fibres is to be marked from 1 to 24.

Figure 28: Identifying optic-fibre trunk cable on patch panel.

2.9.11. Labelling of phone services panel at Floor Distributor rack. For labelling of copper backbone cables, the cable identifier is to be shown at the Top-Left of the termination panel. There will need to be identification of where the pairs of the cable appear but not every pair needs to be labelled.



Figure 29: Labelling of copper back-bone cable at Floor Distributor Rack.

2.9.12. Labelling outlet cabling at Floor Distributor Rack. The width of labels on Panduit rack-mounted panels is insufficient to be able to hold the full outlet identifier. As such the intention is to use panel face-plates that hold two labels for each socket and to split the socket identifier into two. The required approach is for the first two fields of the identifier to be printed on the top label and for the socket sequence number to be printed on the bottom label.

Figure 30: Labelling of outlet-cabling at Floor Distributor Rack.

2.9.13. Labelling outlet cabling at plates and boxes. Each outlet is to be clearly labelled on the front face of the outlet plate using a permanent plastic adhesive label printed in black print on white or clear backing. Where a wall plate contains more than one outlet, there is to be a separate label for each outlet and each label is to clearly indicate which sockets belong each outlet.



Figure 31: Required labelling at telecommunications outlets.

2.9.14. Labelling of dial-out lines at end point. Every dial-out line is to be labelled at the end termination point as indicated below on diagram.

Figure 32: Labelling at end-point terminations for dial-out lines.



3. Testing. 3.1. Copper backbone cables. All copper backbone cables are to be tested as a final step in the installation of the cable.

3.1.1. Requirements for testing. We require that one of the final steps in the installation of a copper trunk cable is that each pair within the cable is tested to ensure that the resistance of each wire is within acceptable limits and that there are no short circuits, broken wires and that the pair sequence is the same at both ends of the cable.

3.1.2. Test specifications. 3.1.2.1. Resistance of wires. The resistance of each wire in the cable is to be measured and the result is to

be less or equal to the values in the table below when that value has been adjusted for the actual cable length.

Wire guage

Diameter (inch)

Diameter (mm)

CSA (mm sq.)

Resistance per 100m

Resistance of looped pair

3.1.2.2. Short circuits. Each wire within the cable is to be tested to ensure that it is insulated from every other wire in the cable.

3.1.3. Test methods.

Figure 33: Measuring resistance of wires in cable using looped pair.



3.2. Fibre-optic cables. All fibres within all cables are to be tested as part of the installation and prior to acceptance by the university.

3.2.1. Requirements for testing. We require that one of the final steps in the installation of a fibre optic cable is to test each terminated fibre within that cable after termination has been completed. Each fibre is to be tested from the through-adaptor in the patch panel at one end of the cable to the through-adaptor in the patch panel at the other end of the cable. Each fibre is to be tested for how much light is attenuated when traversing it as well as to ensure that the sequence of fibres is the same at both ends of the cable.

3.2.2. Testing specifications. The following specifications are to be applied to optic fibre tests.

3.2.2.1. Multi-mode fibres are to be tested at both the 800 nanometres wavelength an the 1300 nanometres wavelength.

3.2.2.2. Single-mode fibres are to be tested at both the 1300 nanometres wavelength and the 1550 nanometres wavelength.

3.2.3. Provision where fusion-splicing is used. When fusion splicing has been used as part of the installation there is to be a minimum of 7 days allowance from when the last splice was installed and when the final testing of that fibre is undertaken.

3.2.4. Testing methods. The preferred method of testing is to use a light source and light meter combination to measure the exact loss of the fibre. An optical time-domain reflectometer can also be used to measure the loss, however it is not regarded to be as accurate or reliable as the use of a light source and light meter combination. It is understood that loss can sometimes be dependent on the direction of the flow of light. As a result it is required that all fibres be tested with light flowing in both directions and that the accepted result will be the highest of the loss readings.



Figure 34: Measuring fibre loss with light source, light meter combination.

Figure 35: Measuring fibre loss with optical time-domain reflectometer.



3.3. Outlet cabling. All pairs within all outlet cables are to be tested as part of the installation and prior to acceptance by the university.

3.3.1. Requirements for testing. We required that each socket in a telecommunications outlet is to be tested once the cable and socket has been installed and the cable has been terminated at both ends. Testing is to take place between the wiring frame and the wall socket. Acceptance by the university of a completed telecommunications outlet is dependent on it passing the test specifications listed below.

3.3.2. Testing methods. It is required that an industry standard cable tester, rated for category 5E standard, be used to test each socket, the cable and the termination at each end.

Figure 36: Testing telecommunications outlet sockets.

The testing of outlet cabling is a specialised process and there is a requirement to pass on those test results to the University. As such, there are a number of testing systems which the University is comfortable with and has approved for testing the installation and accepting the output from. These are listed below. It may be that there are systems available which perform the required tasks and provide suitable output but is not listed among the approved systems. The University is willing to consider the use of such a system but that would have to be discussed with the ITS department of the University and agreement reached prior to the use of such a system.

3.3.4. Testing parameters. There are test parameters that the University considers necessary for the certification of outlet cabling. These parameters are required to be tested and the reported results are to be submitted as part of the outlet testing reports. These parameters are listed below. There are also parameters which may be desirable characteristics to have recorded but it is understood that not every test system measures and are not mandatory in reporting. These parameters are listed separately.

3.3.4.1. Required test parameters. Wire-map - Testing for split pairs, reversed pairs, crossed pairs, open circuits and short circuits.

DC Loop resistance - The loop resistance for each pair.

Length - as reported by a reflectometry test on each pair and recording of longest length.

Attenuation - The transmission loss as measured on each pair.

Near end cross-talk (NEXT) - Between all 4 pairs and record worst reading.

Equal-level far end cross-talk (ELFEXT) - Between each pair and all three other pairs and record worst reading.

Attenuation to cross-talk ratio (ACR) - Performance headroom as calculated from loss and cross-talk measurements.

3.3.5. Acceptance limits. Length - The reported length is not to exceed 90 metres.

Attenuation - The attenuation is to be less than 36dB at 250MHz.

Near-end cross-talk (NEXT) - This cross-talk is to be greater than 33.1dB at 250MHz.

Equal-level far-end cross-talk (ELFEXT) - This cross-talk is to be greater than 15.3dB at 250MHz.

Attenuation cross-talk ratio (ACR) - This ratio is to be better than -2.9dB at 250MHz.

Propagation delay skew - Where this parameter is presented, the maximum permitted skew across all four pairs is 50ns.

3.3.6. Testing performance and tolerances. The accuracy and tolerance limits for the approved products is to known industry standards. Where other equipment is to be proposed, the accuracy and tolerance limits are to comply with the standards set out in Annex A of standards document "SAA/SNZ HB27 : Handbook for field testing of balanced cable installations"



4. Documentation from construction work. To allow the delivery of services and the support of services, the following items are required to be delivered to the University and a copy provided to the ITS Department:

4. 1. TCA form (ACMA regulatory document). The University requires that all communications cabling be installed by an ACMA licensed installer and that the cabling is installed according to appropriate standards and rules. At the end of installation, and prior to delivery of communications services, the installer needs to lodge an ACMA TCA form with the University to show the cabling plant is compliant with regulations. The ITS department needs to sight such form as an indication that services are permitted to be delivered over the cabling.

4.2. Panduit certification of outlet cabling. The University requires the installation of outlet cabling to be installed and certified to the Panduit certification and warranty process. The University needs to receive the relevant certification and warranty forms. ITS needs to sight those forms as evidence of the quality and performance of the outlet cabling system.

4. 3. Construction document “As built” drawings. For the University to be able to deliver services over the outlet cabling plant, there needs to be knowledge of the location of all outlets installed. This can only be provided by marked up drawings. As this information is required for the delivery of services, the ITS department is willing to receive hand marked-up drawings, to allow this information to be expedited.

4.4. Cabling test results. The University requires the use of specialised testing/certification equipment to verify the correct installation and performance of all fibre-optic cables and outlet cabling. The testing records from these test needs to be provided to the University as proof that cables have been correctly installed. As these records are very voluminous for a project and are often in the form of vendor specific formatted files, the University requires them in the form of PDF format files delivered on CD or DVD disks.
