Antenna alignment
A fixed-wireless lobe sweeps either side of the surveyed bearing while a strength bar tracks what it finds, then converges on the peak notch and the lock mark returns.

Accessnet
15 animationsAppointment window
An install window sits on a day rule of hour ticks, widening out to a half-day span and closing symmetrically back onto the confirmed two-hour slot.
CSSCross-connect
A jumper cord in a street cabinet retracts from its terminal, re-lands two positions down the distribution strip and then returns, the live terminal tick following it.
CSSCrosstalk vectoring
Signed crosstalk residual bars stand either side of a baseline; the canceller sweeps left to right and each residual collapses onto the rule until the line reads flat.
CSSDemarcation point
A measured span above the service line reaches from the network terminal to the dashed demarcation, then extends across it to take in the customer segment and light the premises terminal.
CSSDrop cable
A slack drop strand runs from the aerial terminal down to the premises box while a dash train travels its length and the service lamp inside the box holds live.
CSSLoop qualification
An attenuation curve falls away from the exchange while the qualified reach grows out along it to the minimum-rate rule and drops a marker onto the distance axis.
CSSOptical splitter
A one-to-four passive split tree lit end to end; the light recedes from the outer stage back to the splitter block and then propagates outward again, stage by stage.
CSSOptical terminal
Four status lamps on a premises terminal drop together and come back up in commissioning order - power, fibre, sync, service - then hold steady at online.
CSSPremises mesh
Three in-home mesh nodes push their coverage discs outward in turn until the edges meet across the partition walls and the dead spot between them closes.
CSSRate shaping
A token reservoir is drawn down in bursts and refilled at a constant trickle while the shaped outlet below keeps leaving at exactly the same rate.
CSSService activation
Three provisioning stages take an activation front that wipes across them left to right, and a completion tick lands once the last stage is through.
CSSSpectrum split
A channelised frequency band divides into upstream and downstream blocks; the upstream block takes channels and the downstream block gives up exactly the same share, so the mid-split boundary steps up with no seam.
CSSSync rate
A dial needle rests on the provisioned-rate notch, drops to the floor of the scale and climbs back through a small overshoot while the accent arc reads the same value along the dial.
CSSUpstream ranging
Three upstream bursts sit aligned in consecutive timeslots of a frame ruler, scatter to their own equalisation offsets and slide back into slot without overlapping.
