Data & comms
Data points, patch leads, PoE and structured cabling.
Data outlet has no link / no network
A device plugged into a data outlet gets no link or no network, while others work — pointing at the patch lead, the outlet termination, the cable run, or the patch panel/switch port.
Data cabling run fails certification / wiremap fault
A structured cabling run fails a tester (wiremap fault, open, short, split pair, or excessive length) — so it won't reliably carry the network even if a link sometimes appears.
PoE device (camera/AP/phone) not powering up
A Power-over-Ethernet device (IP camera, wireless AP, VoIP phone) won't power on over its data cable — pointing at the PoE source, the budget, the cable, or the device's PoE class.
Data connection slow, dropping, or unreliable
A data point links but is slow, drops out, or negotiates a low speed — pointing at cabling quality, a marginal termination, interference, or the run length, rather than a hard break.
Phone/analogue line dead (no dial tone)
An analogue phone/fax/EFTPOS line is dead — no dial tone — pointing at the line in, the socket/wiring, or the device, in premises that still use copper voice services.
TV antenna outlet — no or poor signal
A TV outlet has no signal or poor/pixelating picture while others are fine — pointing at the outlet/lead, a splitter/amplifier, cabling, or the antenna/head-end.
