@blackforestmesh @bbk die Abschaltung des #HyTNAS samt #Notspeisung zugunsten von #Vectoring-Shice halte ich genauso für falsch wie die mangelnde #Funküberwachung von #27MHz-CB-Funk auf #CEPT-Kanal 9 (FM) sowie Umsetzung von #eCall aif #GSM-basis statt CB!

  • Davon dass die staatliche Nahrungsmitelbevorratung eingestampft wurde ohne Ausgleich für die Bevölkerung oder die massenhafte Nutzung veralteter (!!!) #Windows-Systeme in #BOS|en & #KRITIS hab' ich noch garnicht angefangen.

@paavi @kurth @John_Loader @amiserabilist @MAJ1 @kibcol1049 actually fmr. GDR until the completion of #HyTNAS (digitalization of the German #PSTN based off #ISDN + #ADSL Annex B from the first outdoor switch onwards!) there were even some 1920s mechanical dialing systems still in use.

  • Needless to say it was considered "worse than a fully destroyed modern network" because it was stuck on pre-1939 capacity.

@Paradox Germany canceled that in 1997 with the nationwide implementation of #HyTNAS (ADSL Annex B + ISDN + PSTN on a single pair).

@nofollownoindex @cR0w @Dio9sys @da_667 #Tenda #EoL'd such new hardware?

  • Shit, that reminds me that some folks just recently got themselves some #4G06 & #4G07 units because they needed a cheap #VoLTE - #FWT to hookup seniors' landline phones on because it's cheaper to migrate to #sipgate / #simquadrat than having to swallow a forced migration from #AnnexB - based #PSTN (#HyTNAS) to shitty and overpriced #VDSL!

@hisold IMHO ist die @BNetzA viel zu lax und sollte harte Mindesversorgungskriterien samt SLAs vorschreiben und Neubau von #Koax- & #Kupferkabel (#DOCSIS & #VDSL) verbieten und #FTTH als gesetzliche #Grundversorgung vorschreiben und dafür das #HyTNAS als Basisdienst wieder aktivieren...

@adlerweb @schnedan @tofuknacker 100Gbit/s - Ethernet ist nur auf Backplanes (100GBASE-CX4) Mit Kupferkabel spezifiziert.

  • Jenseits von 40GBit/s geht nominell nicht und schon 40GBaseT bedarf Cat. 8.1 - Kabel, wohingegen hierzulande i.d.R. nur Cat. 2 oder Cat. 3 aka. ungeschirmte Doppeladern verlegt sind.

#xDSL war schon in den 80ern absrhbare #Krückentechnologie, wohingegen selbst stumpfe #FFDI-Faser mit ertüchtigten Kupplungen auf OS2 Upgegraded ubd somit 100GBit/s pro Faserpaar realisieren kann.

  • Und so sehr ich kein Fan von #GPON bin, so ist es anders als #DOCSIS und #HyTNAS sowie #VDSL-BSA nicht aufgrund von Nutzern extrem störanfällig!!!

@bee8bit @sabi not only that but with the #HyTNAS the entire system was #ADSL Annex B and every call got converted to #ISDN from the #PoP / #DSLAM / Switchbox onward since 1997.

@drwho @sabi depends on the #POTS / #PSTN system.

In some cases, that may be it...

  • But I usually don't consider vandalism as a valid strategy when cyber-nomading...

The 2.400bps limit is what can be achieved with a Konnex Konnector Acoustic Coupler on the carbon/graphite mic & speakers of #US payphones...

In #Germany, your limit was 56kBit/s or 64kBit/s because #HyTNAS means you always get a V.92-capable line that gets switched to (also permanently present, but potentially disabled) #ISDN channel if you can just replace the handset, but with the absurd decision by @BNetzA to allow #DTAG to shutdown the #HyTNAS in favour of shitty #Vectoring-#DSL / #VDSL you can't get shit to work at all...

@rnbastos @foone yeah... RIP #HyTNAS...

@bamfic @foone that died with #HyTNAS in #Germany and even then since 1997 it was at least #ISDN from the local switchbox onward...

@izaya @foone yesh, for some bs reason @BNetzA allowed #DTAG to shutdown #HyTNAS even tho this means a lot of places that can't do even #ADSL2+ beyond 6MBit/s reliably are getting shafted hard...

@yetzt persomally, I think the #privatization of #DB as well as #TankUndRast as well as letting #DTAG keep the #PSTN (#HyTNAS) once privatized were fundamentally wrong.

@amy You've to thank #DTAG for that since they shut down the #HyTNAS.

Otherwise I would've stayed on #ISDN!

@jwildeboer yeah.

Worse: @EU_Commission had to step in and ban #subsidies for #Vectoring (didn't do so for other crudges like #DOCSIS)...

IMHO tue @BNetzA should not have allowed the shutdown of #HyTNAS for shitty #Vectoring and instead the Government should've mandated the building and deployment if #OpenAccess #FTTB & #FTTH networks.

@aurora not really, #DTAG is know to sabotage #FTTB & #FTTH to the point that they openly lie and competitiors have to sue them.

For example they started claiming that #NetCologne would hut down their network amd cease business (which is absolute horseshit!)...

Not to mention they start doing that shitty bodge tech aka. #VDSL in lieu of delivering actual #OpenAccess-FTTH or following their obligation to maintain the #HyTNAS that does Analog, ISDN & ADSL on a single pair.
