TasNetworks Standard - Communications and Data Cabling Standard1 General1.1 PurposeThe purpose of this document is to define the requirements, specifications and application of allcommunications cabling and terminations to be installed on substation and telecommunications networksites owned and operated by, or under the responsibility of, Tasmanian Networks Pty Ltd (hereafter referredto as “TasNetworks”). This includes cabling used for communications to protection and control devices, datacabling and cabling used within the TasNetworks’ telecommunications network.1.2 ScopeThis standard applies to all communications cabling carried out by TasNetworks’ employees, contractors, orany other person or entity providing cabling in substations or telecommunications facilities underTasNetworks’ responsibility.1.3 ObjectiveThe basic objectives of this standard are to: Protect the health and safety of any person who may operate; work on; use services supplied bymeans of; or be otherwise reasonably likely to be affected by the operation of; atelecommunications network, telecommunications facility, telecommunications facility, substation,asset or sites that are owned and operated by, or are under the responsibility of, TasNetworks;Protect the integrity and proper functioning of a telecommunications network, telecommunicationsfacility, substation, asset or sites that are owned and operated by, or are under the responsibility of,TasNetworks; andTo ensure that where practical a standard approach and philosophy is used to design, operate andmaintain assets and sites that are owned and operated by, or are under the responsibility ofTasNetworks.1.1 PrecedenceAny apparent conflict between the requirements of this standard and the law, mandatory requirements,industry standards, project specifications, non-statutory standards or guidelines, and any other associateddocuments should be brought to the immediate attention of TasNetworks’ for resolution. No action must betaken that might result in a breach of law or mandatory standard.Where there may be a conflict between the requirements of this standard and any: law, mandatory requirement, or industry standard, then: that law or statutory requirement willprevail over this standard; andnon-mandatory standard or guideline, then: this standard will prevail over that standard orguideline; orproject specification, then the contract documentation will prevail over this standard.If other TasNetworks’ cabling standards conflict with this telecommunications standard such as theTasNetworks’ power cabling standards, this standard shall take precedence.Page 8 of 32

TasNetworks Standard - Communications and Data Cabling Standard1.3.2.5 Cross-connectionA method of providing for flexible interconnection of cables or cable elements, by means of jumpers or patchcords.1.3.2.6 CustomerA legal person, including a natural person, a corporation or an organisation, that subscribes to (pays for) thesupply of a carriage service.Note: for most purposes of this standard, TasNetworks’ Protection and Control can be considered as acustomer of the TasNetworks’ Telecommunications Operations team.1.3.2.7 Customer access equipment (CAE)Customer equipment with multiple ports (local or network) that provides access (gateway functions) to atelecommunications network and is capable of switching, storage, processing, conversion, integration, lineisolation/coupling or multiplexing of analogue or digital voice or voice equivalent communication.Note 1: examples of CAE include, but are not limited to, PABX or key systems, line isolators, ISDN terminaladapters, echo cancellers, interactive voice response systems, voice/packet gateway, integrated accessdevices, voice messaging systems, protection relays and remote terminal units (RTUs).Note 2: CAE is a type of customer equipment but, for the purposes of this standard, is not considered to be“terminal equipment”. An operator console, telephone handset or any other peripheral device connected toCAE that may be regularly handled by an end-user is “terminal equipment”.Note 3: CAE was formerly referred to as CSS (Customer Switching System)1.3.2.8 Customer cabling and equipmentAny line (cabling) or equipment, apparatus, tower, mast, antenna, or other structure, or system (softwarebased or otherwise) that is used, installed ready for use, or intended for use on the customer side of theboundary of a telecommunications network.1.3.2.9 DistributorA collection of components used to terminate cables which provides for cross-connection of cables or cableelements, e.g. a fibre-optic patch panel or a Krone frame.Note: Any cable termination equipment used to connect two or more cables or cable elements togetherwithout cross-connection (e.g. a cable joint) is not regarded as a distributor for the purposes of thisstandard.1.3.2.10 Earth Potential Rise (EPR)A rise in voltage of an earthing system and the surrounding soil with respect to a distant earth. EPR is causedprimarily when an earth fault on an HV or EHV power system produces a current flow through the earthingsystem of an HV or EHV site.1.3.2.11 End-userThe customer or any other person that may use a carriage service, e.g. an employee of the customer.1.3.2.12 Extra-High Voltage (EHV)Refer to section 1.7.3: Voltage Classifications.Page 14 of 32
TasNetworks Standard - Communications and Data Cabling Standard1.3.2.13 Extra-Low Voltage (ELV)Refer to section 1.7.3: Voltage Classifications.1.3.2.14 Functional earthThe earthing of a point in equipment or in a system which is necessary for a purpose other than safety, e.g.as a reference voltage for a telecommunications circuit.1.3.2.15 High Voltage (HV)Refer to section 1.7.3: Voltage Classifications.1.3.2.16 Indoor cablingCustomer cabling that is installed inside a building but not underground or exposed to the elements.Note: cabling installed within a sheltered structure between buildings such as a service tunnel, coveredwalkway or above-ground trunking system, is treated as indoor cabling for certain requirements of thisstandard (e.g. cable properties and separation from other services).1.3.2.17 Isolation deviceA device that isolates each of the conductors of a telecommunications service to prevent the transfer ofhazardous voltages but allows the service to operate normally. For example an optical isolator.1.3.2.18 JumperA cable unit or cable element without connectors, typically one to four twisted pairs, either unsheathed orsheathed, used to make a cross-connection within a distributor.1.3.2.19 Low Frequency Induction (LFI)The generation of currents in a telecommunications line due to inductive coupling with a power line carryinglarge unbalanced currents e.g. during a fault condition on the HV or EHV power system.1.3.2.20 Low Voltage (LV)Refer to section 1.7.3: Voltage Classifications.1.3.2.21 Main distribution frame (MDF)A distributor that provides, or is intended to provide, an electrical termination point for a communicationsservice provider’s twisted pair lead-in cabling.Note: for the purpose of this standard, the TasNetworks’ Telecommunications Operations team can beconsidered as a communication service provider providing services to customers including TasNetworks’Protection and Control amongst others.1.3.2.22 Network boundaryRefer to Section 2.8: Network Boundary.1.3.2.23 Outdoor cablingCustomer cabling that is installed external to a building, either underground or exposed to the elements.Note: cabling installed within a sheltered structure between buildings such as a service tunnel, coveredwalkway or above-ground trunking system, is treated as indoor cabling for certain requirements of thisstandard (e.g. separation from other services).Page 15 of 32
