Title: 6 months uptime on DSL?
Post by: TheBoy on 26 December 2006, 00:49:25
The line that this forum is running from has a DSL sync time of around 5.5 months:

System up:   168 days 13 hours 17 minutes
Line up:     167 days 17 hours 41 minutes

Notice, that is line up time, not router up time :D

Reckon it will make it to 6 months?

Anyone had better?

I work for an ISP, and deal a lot with DSL and leased lines...

Looks like you're on a good circuit whatever the case.

But... DSL? Get it behind a megastream ethernet :D

Who do you work for, if I may ask...?

Server but not line - I told off (humourously) a customers IT department as it had been rebooted after I had last found an uptime of 540 days.

Many of the servers I look after have uptimes of over 700 days. But they are Solaris ones....

A LES100 type circuit would be nice, but out of my price range. Unless OOF members want to pay for one :p

If it was a DSL line in my area, it would probably have a peak uptime of 6 hours!!

Why is your area bad - long way out from exchange?

BT's implementation of DSL is actually quite good, and everyone should see uptimes of a month or so easily, unless on a long line.  The router makes a big difference as well - many cheaper DSL routers do all sorts of stupid things (then ultimately panic) under heavy traffic. Belkin, Netgear, BT Voyager 2xx range all do this.


The actual line length of this line is 3.5km. The router is a Siemens unit. But this uptime is still the best I've ever seen on a DSL circuit.

I would like ASDL but currently slumming it on a modem card - I suppose first use except for trying and failing to fax in 3 years it is OK.

Perhaps I should get them to replace home highway for 5 days

I live in the town centre, so I shouldn't be too far from the exchange! It's just rubbish and I don't think it can handle the load that it has been tasked with (the exchange that is). My router is a 3Com OfficeConnect. Quite decent, and the firmware is fully updated. The average uptime is actually a good few days/months, but I had all kinds of teething problems and at times there have been several total connection losses lasting a good few hours. Basically have had a shit customer experience from start to date, since switching from Cable to ADSL.

I'm not even going to rant about the contention ratio difference and speeds you get compared to my cable connection.

The majority of us cannot get cable.  I (currently) wouldn't swap my DSL connection for cable if I could.

If you're seeing heavy exchange contention, that is likely because you are on a 'consumer' Max product?  Which ISP as well, as many are now heavily traffic shaping (esp the 'unlimited' ones), knobbling p2p traffic (rightly so, not just for illegal aspects either)

Does that town have its own exchange?

What are your line stats (iirc, that 3com is weak on giving line stats).  Also, unless 3com have released another firmware recently, its been a while since previous (and security flawed one).

Also, see if you can borrow another router, just to test - I never found those 3coms much good, esp under heavy traffic, or marginal lines...

(I assume your 3com is the one they have sold for about 2 yrs for around £40, usually with free laptop/usb card? If not, ignore me ;))

What router do you use?

Mine's okay (not tempting fate right now by naming it - not one so far mentioned) but I'm let down by power and as often as not any resets are caused by lack of electrons (mains varient).

- other than the self-inflicted "testing" of the RCB!

Siemens sb5830....    ....probably best ADSL router I have come across, equal imho to the Cisco 827/837, and (like the Cisco) not bogged down with wireless crap on it...

Its transferred some data in that time as well - as I'm sure you can imagine, this forum uses several Gb per month....

Time for a new poll "will the DSL line stay up for 12 months?"

though I here that BT are going to be carrying out some DSLAM work over the next couple of months, so that will probably kill it... :(
