Signaalwaardes EuroDocsis2 en EuroDocsis3 modems.

yukhalilsel · 27 apr 2014

Dit zijn de waardes op mijn Cisco EPC3925.

Ik heb er geen AOP tussen. De groene wijkkabel zit direct op een splitter waarbij een kabel naar mijn modem gaat en de ander naar de decoder.

Als ik het goed heb begrepen zijn dit prima waardes?

melvintje · 27 apr 2014

Zijn inderdaad prima waardes

coco · 28 apr 2014

Zeker niet prima.
Upload power levels zijn niet erg goed.( zijn te hoog ).

yukhalilsel · 28 apr 2014

Wat kan ik zelf ondernemen om de upload power levels te perfectioneren? Want ik haal te allen tijde zonder enig probleem de maximum snelheden van mijn abonnement

RobertWebbe · 28 apr 2014

Als je altijd goede snelheidsresultaten haalt, waarom zou je je dan druk maken? Je krijgt er niet nog meer snelheid van. Wat me opvalt is dat je geen AOP hebt, dat zou ik wel doen. Een dubbele galvanische scheiding is verplicht, het voorkomt namelijk storing, onweer of andere problemen die de werking van je apparaten kan beïnvloeden. Leg hem wel aan aarde als je aarding in de buurt hebt. Als je het liever zelf doet, hier kun je originele UPC AOP's kopen: https://www.cablers.nl/epages/Cablers.sf/nl_NL/?ObjectPath=/Shops/Digiproof/Products/44000271.

Toen ik hierheen verhuisde,zag ik de groene kabel los uit de muur steken en heb later geen moeite genomen om over een AOP te piekeren.

Maar ik zal er eens over bellen met HD om te zien of zij dat willen aansluiten.

Vraagje: Zijn er ook gebieden bij UPC waar de upstream modulatie 64-QAM is i.p.v. 16-QAM?

Vanwaar deze vraag? Ik heb een uitbreiding gemaakt aan mijn DOCSIS parser tooltje zodat voortaan ook de inhoud van de MAC Domain Descriptor (MMD) en de Upstream Channel Descriptor (UCD) getoond wordt. Deze twee descriptors worden door de CMTS naar de kabelmodems verzonden met informatie over de DOCSIS configuratie van het coaxsegment. Ik heb daarom even alle Internet downstream capture bestanden uit UPC en Ziggo gebied opnieuw door het tooltje gehaald waarbij het me opviel dat in de captures uit UPC gebied 16-QAM wordt gebruikt voor het "Advanced PHY Short Data Grant" en "Advanced PHY Long Data Grant" gebruik van de EuroDOCSIS 3 upstream kanalen terwijl dat bij Ziggo 64-QAM is.

Dat zou een verklaring kunnen zijn waarom UPC er enige tijd geleden voor gekozen heeft om de upstream snelheden te halveren. Een lager modulatie type zorgt immers voor een lagere capaciteit per upstream kanaal. Bij 64-QAM is dat netto zo'n 27 Mbps per upstream kanaal volgens diverse websites. De netto waarde bij 16-QAM zal zo'n 17 à 18 Mbps per upstream zijn. Hoewel beide kabelbedrijven kabelmodems gebruiken die 4 upstream kanalen kunnen configureren maakt UPC daar dus niet optimaal gebruik van door de EuroDOCSIS 3.0 modems ook met 64-QAM modulatie te laten zenden. Misschien is het coax netwerk van UPC niet geschikt voor 64-QAM modulatie in de upstream, want 16-QAM modulatie stelt minder hoge eisen en is daardoor minder gevoeilig voor verstoringen.

Hier bij mij in Arnhem 16-QAM

Ik heb dit topic doorzocht tot ongeveer juni 2012 en kom dan alleen maar 16-QAM tegen als upstream modulatie. Een zoekactie op 64QAM op het forum levert wel twee resultaten op, namelijk van:

kees-1953 in maart 2013 (https://ziggoforum.nl/posts/631761/)
hansvk in december 2012 (https://ziggoforum.nl/posts/615938/)

Ik heb echter geen idee of er bij deze twee personen nog steeds sprake is van 64-QAM modulatie bij de upstream kanalen of dat UPC dat in hun coaxsegmenten ondertussen ook verlaagd heeft naar 16-QAM.

In Haarlem is er zelfs nog sprake van twee extra upstreams met de lagere QPSK modulatie naast de vier upstreams met 16-QAM modulatie. Onderstaande post van Devil-Strike.net uit september 2013 laat zien dat die twee upstreams ook op zijn kabelmodem geconfigureerd waren:
