Title: Every FTTC Cab Lost Sync on Exchange
Post by: jid on March 18, 2015, 12:20:19 AM
Strange one this evening. Was watching tv and on the web when all of a sudden everything went.

Checked the modem, no sync (No Signal) showing on the HG612 gui.

Was speaking to a friend at the time on the same exchange, different cab and he said his had done the same. Live about 10 mins from me.

Seems a coincidence the cabs both lost sync, possible the G.INP upgrade being rolled out  ??? Either way, lasted about 5 mins. No outages reported by TalkTalk, and I doubt they'd be responsible for no sync?

Possible... or with it being both cabs at the same time perhaps something on the backhaul/OLT.  As you correctly say, it cant have been TT to cause a loss of sync.

A friend round the corner on a different cab just text me saying did I lose sync. Seems something peculiar going on. Only time will tell if G. InP appears

Not in the affected area codes and not with Plusnet, seems a separate issue perhaps  ???

I was refering to a possible bigger event or its recovery process that had affected both TT & Plusnet.

Sorry if not clear, late night and fingers that don't work. ;D

I can't see how anything on the backhaul or OLT could affect the synchronisation of a DSLAM/MSAN with a CPE.  :-\  For example, Big Barry could have dug through some ducting which carries the fibre optic cables from the head-end to the various cabinet DSLAMs/MSANs. The service would obviously stop but all DSLAMs/MSANs and CPEs would still be in synchronism.

How about a short power cut, affecting only the supply to the cabinets and not to your houses?

Plus, this affecting numerous cabinets over a 5 mile or so radius. I would highly bet a G.INP rollout. Only time will tell.

b*cat nods.  :)

It seems as if a control signal was sent out to the group of DSLAMs/MSANs which initiated a synchronisation drop at the beginning of some process. Once that process had concluded, another control signal initiated the resynchronisation of the DSLAMs/MSANs and CPEs.

Think you're right Mr B*cat there was downtime for exactly 10 minutes, so its seems a planned thing.

Ive just had a weird outage @ 00:00:37 according to my logs it just says LCP Down. Reason:0 lower down

Came back up at  00:50:27 VDSL link up.
Not sure what (if) other cabs were affected but seems strange to happen bang on midnight.  50 mins is a long time for a software upgrade though.  :-\

I bet you have been G.INP'd  ;D ;D

Can your line get any better ?  ;D

Just jealous as my line has dropped even with G.INP.  :(  ???

Im on an ECI cab..  and no g.inp as Im not interleaved anyhow.   
From what I can see, no change in my stats aside from an extra 0.1db of SNRm.

Did know you were ECI .... then forgot <Senior Moment ... Oops>

Aware of all the 'angst' regarding ECI and will it / wont it be G.INP'd.
(Or if it is happening now or later ...... according to someone [naming no names] on Plusnet Forums  ;D)
