ANSI/TIA-570-E
Updated 2026-10-25
Data records
- Clause 3.2 of ANSI/TIA-570-E (2024) defines the auxiliary disconnect outlet as a device, normally inside the dwelling unit, that lets the access provider service be connected or disconnected, with the ADO cable linking it to the distribution device or demarcation point.
- A note to clause 10.1 of ANSI/TIA-570-E (2024) treats data cabling as four-pair balanced twisted-pair or optical fiber cabling with a connector at each end.
- Clause 3.2 of ANSI/TIA-570-E (2024) defines the distribution device as the facility inside a dwelling unit where outlet cables are interconnected or cross-connected, and it may be passive, active or both.
- Clause 3.2 of ANSI/TIA-570-E (2024) uses the term outlet cable for the cable that runs between an equipment outlet and the distribution device of the dwelling.
- Clause 10.5.3 of ANSI/TIA-570-E (2024) allows a coaxial performance characterization under ANSI/TIA-568.4 to take the place of verification or qualification.
- Clause 10.5.2 of ANSI/TIA-570-E (2024) requires optical fiber cabling to be tested under ANSI/TIA-568.3 and adds no method, wavelength or loss budget of its own.
- Clause 10.4 of ANSI/TIA-570-E (2024) requires qualification, which shows the cabling will carry the intended applications, to be done with the application equipment connected or with a qualification test instrument, and prefers it to trim-out verification for voice and data.
- Clause 10.1 of ANSI/TIA-570-E (2024) requires acceptance testing of all residential telecommunications cabling, voice, data, video, security, audio and control alike, with every run receiving a visual examination and a verification test and data cabling also receiving either a qualification test or a performance characterization.
- Clause 10.5.1 of ANSI/TIA-570-E (2024) evaluates twisted-pair performance characterization against the ANSI/TIA-568.2 limits for the category of the installed cable, measured as a permanent link or a channel, with no relaxation for residential use.
- Clause 10.3 of ANSI/TIA-570-E (2024) defines verification as an end-to-end connectivity check; for twisted-pair it covers wiremap, length, continuity, shorts, crossed, reversed and split pairs and other miswiring, and for coaxial cable it covers continuity to the far end and freedom from shorts.
- ANSI/TIA-570-E (2024) expects verification at two stages, at rough-in before the walls are closed and again at trim-out after painting, and its note to clause 10.3 says a qualification or characterization test of data cabling generally makes the trim-out verification unnecessary.
- Clause 10.2 of ANSI/TIA-570-E (2024) requires each cable run to be visually inspected once installed and before insulation and wallboard close the walls, looking for damage, separation of metallic cable from interference sources, bend radius and excess length.
- Clause 11 of ANSI/TIA-570-E (2024) requires each run in a single dwelling to be labeled at both ends and listed on a label inside the distribution device, leaves outlet labels optional, and administers multi-dwelling buildings like commercial ones under ANSI/TIA-606.
- Annex A of ANSI/TIA-570-E (2024) is informative guidance on planning, design and construction, covering distribution device placement, outlet mounting heights, pathways in interior walls and the extra spaces needed when outlet runs would grow too long.
- Annex B of ANSI/TIA-570-E (2024) is an informative project planning guide that walks through pre-wire, trim-out, the testing sequence and the handover, including handing the owner a copy of the results recorded for each run.
- Annex C of ANSI/TIA-570-E (2024) is an informative bibliography that includes the multimode installed-loss test standard ANSI/TIA-526-14, outside plant and network security standards, and the TIA bulletins on access point cabling, power delivery and distributed antenna systems.
- The introduction of ANSI/TIA-570-E (2024) applies the standard to new construction as well as additions and remodeling of single-dwelling and multi-dwelling buildings.
- Clause 1 of ANSI/TIA-570-E (2024) lists the residential applications its cabling supports, including voice, data and video with local networks and wireless access points, security and intercom, whole-home audio, and control systems such as home automation and lighting.
- Clause 8 of ANSI/TIA-570-E (2024) requires cables and connecting hardware to suit their environment and holds twisted-pair, coaxial and optical fiber components to ANSI/TIA-568.2, ANSI/TIA-568.4 and ANSI/TIA-568.3 respectively.
- The foreword of ANSI/TIA-570-E (2024) lists two changes from the D edition: updated references and the recognition of balanced single twisted-pair cabling under ANSI/TIA-568.5 as a cable type.
- Clause 6.2.3 and clause 6.2.4 of ANSI/TIA-570-E (2024) place the demarcation point, usually on an exterior wall, and require an indoor, readily accessible auxiliary disconnect outlet wherever no other convenient means of disconnecting the access provider exists.
- Clause 6.2.6 of ANSI/TIA-570-E (2024) requires a distribution device in each residence, located inside the tenant space with maintenance access and with nearby access to the building electrical ground, and recommends space at it for surge protection of each conductive cable entering the building.
- Clause 6.2.2 of ANSI/TIA-570-E (2024) defines three grades of residential cabling by the minimum twisted-pair, coaxial and optical fiber cables required at each cabled location, with augmented Category 6 twisted-pair as the floor for every grade and optical fiber optional except in the highest grade.
- Clause 9 of ANSI/TIA-570-E (2024) sets installation practice for each cable type, including firestopping of pathways, secondary protector placement, bend radius and pulling tension under ANSI/TIA-568.0, female F-type coaxial terminations and the security panel line-seizure interface.
- Clause 9.2.3 of ANSI/TIA-570-E (2024) classifies a twisted-pair link built from components of different categories by its lowest-performing component and limits pair untwisting at terminations.
- Clause 7 of ANSI/TIA-570-E (2024) covers multi-dwelling buildings and campuses, requiring owner control of shared spaces, bonding under ANSI/TIA-607 and provider spaces reachable from common corridors, and recommending a common telecommunications room on each floor or every few floors.
- Clause 2 of ANSI/TIA-570-E (2024) names as normative the generic, twisted-pair, optical fiber, coaxial and single-pair cabling documents of the ANSI/TIA-568 series, together with the pathway, administration, bonding, intelligent building and terminal connection standards and the electrical and fire alarm codes.
- Clause 6.2.7.1 of ANSI/TIA-570-E (2024) requires outlet cable to be laid in a star, caps the twisted-pair and coaxial outlet cable length and the total cord length per channel, and lets optical fiber reach further where the application allows.
- Clause 6.2.8 of ANSI/TIA-570-E (2024) requires a cabled outlet location in each kitchen, bedroom, family room, office and home theater, and recommends further locations by wall-space spacing and floor-line distance.
- Clause 8.2.2 of ANSI/TIA-570-E (2024) requires the eight-position residential outlet to meet the IEC 60603-7 interface and to be wired to the T568A assignment, and it requires the outlet to keep its contact performance after repeated insertion of a six-position plug.
- Clause 6.2.7.1.1 of ANSI/TIA-570-E (2024) recognizes augmented Category 6 four-pair twisted-pair, two series of broadband coaxial cable, single-mode or multimode optical fiber cable with a minimum fiber count, and balanced single twisted-pair as outlet cable, each meeting its ANSI/TIA-568 component document.
- Clause 4 of ANSI/TIA-570-E (2024) states that the standard does not replace any code, requires local code requirements to be followed, and aims to be consistent with NFPA 70 and IEEE C2.
- Clause 6.3 of ANSI/TIA-570-E (2024) covers security and fire alarm cabling, placing sensor and device locations under NFPA 70, NFPA 72 and local rules and recommending a star from each supervised sensor back to the control panel.
- Clause 5 of ANSI/TIA-570-E (2024) recommends a star for twisted-pair and optical fiber cabling and requires broadband coaxial cabling to be either a star or a bus-and-star arrangement.
- Clause 6.4 of ANSI/TIA-570-E (2024) divides whole-home audio cabling into three legs, from head-end to distribution device, to each volume control and on to the speakers, and requires speaker conductors plus augmented Category 6 twisted-pair on each leg.
- Clause 12 of ANSI/TIA-570-E (2024) recommends that cabling for wireless access points follow TIA TSB-162.
