Ik vermoed dat geel knipperen initial ranging is (opbouwen upstream), bij mijn UBC1318ZG neemt dit ook slechts enkele seconden in beslag vanwege een vrij lage vereiste Tx power.

hmm alright. zolang ik nergens last van heb kijk ik eigenlijk niet in die waardes. als er echt wat mis is merk je dat wel en dat zijn die waardes wel handig

Laat de historie iets ongebruikelijks zien? De lichte CER in de downstream lijkt vooralsnog wel te zijn opgelost.

voor nu nog niet als heb ik het gevoel dat dat soms totaal anders kan zijn

Na de reset van gisteravond zijn er geen events geweest, dus dat verklaart niet de traagheid van vanmorgen, ervaar je dit nog steeds?

nee op dit moment niet meer alle streaming diensten zoals youtube netflix e.d doen het ook weer vloeiend

We kunnen het beste de resultaten van de door Paul gestarte meting afwachten.

[MR_CHIP]

ik ben benieuwd hoeveel dagen zoan meestal duurt , zo snel al fouten na rs is toch niet goed

[tobiastheebe]

Volgens mij loopt een meting meestal een kleine week. Uncorrectable errors mogen buiten werkzaamheden of bekende storingen niet oplopen.

Hi @MR_CHIP 

We hebben je verbinding gemonitord de laatste dagen en zien eigenlijk weinig opvallende zaken en geen ongeregeldheden (gelukkig). Alleen op 15 juni 2023 rond 18.50/19.01 uur is te zien dat het modem even offline was.

Als je toch op een later moment problemen ervaart doen we natuurlijk graag verder onderzoek. Het is dan voor ons belangrijk dat je de momenten dat dit zich voordoet je die noteert met datum en tijd, zodat we dat naast onze gegevens kunnen leggen. Ook vernemen we dan graag wat je precies merkt per storingsmoment.

[MR_CHIP]

excuus was effe op vakantie onverwachts, wat me wel opvalt is dat het kanaal is gezakt qua frequenties maar gestegen is qua FFT type geen idee wat dat betekent

[tobiastheebe]

Het OFDM-kanaal begon eerst inderdaad op 879 MHz, maar wordt verbreed van 119 naar 168 MHz (hier uitgevoerd op 21-6), waarbij de eerste subcarrier begint op ~830 MHz en de SC-QAM-kanalen -24 MHz worden verplaatst om hiervoor plaats te maken, het gebruikte frequentiespectrum wordt dus nog bewust beperkt tot 1 GHz. Het type FFT (Fast Fourier Transform) houdt verband met de breedte van de subcarriers, deze kan 25 of 50 kHz zijn (8K of 4K). Ziggo heeft altijd 50 kHz c.q. 4K gebruikt, daar is niets aan veranderd.

[MR_CHIP]

sorry het ging over het upstream kanaal

[tobiastheebe]

Ik ging automatisch van het OFDM-kanaal uit omdat in je vorige reactie niet de gegevens van het OFDMA-kanaal stonden. Hoe ziet OFDMA er nu uit?

[MR_CHIP]

hier staat first subcarriers 386Mhz?

[tobiastheebe]

Het OFDM-kanaal is bij jou inmiddels ook verbreed naar 168 MHz maar is inderdaad vreemd genoeg verplaatst naar 368 MHz. Ik weet niet hoe dat is geregeld, omdat DVB-C van 266 tot 538 MHz loopt.

[MR_CHIP]

er was onlangs onderhoud aan televisie signaal
