Re: [swinog] VDSL/Zyxel P2802 HWL not "strong" enough for a smallcompany LAN?

What kind of Setup did you have on the Dislam... Please check if the link is 
going down... If yes. Swisscom should reduce the Traffic rate on the line. 
Standard is the max. by 25000. Some line must be fixed on 2 or less...

Greetings Xaver

Salut Olivier,

We are using ZyXEL ZyWALL1050/USG1000/USG300 behind various P-2802.

In most case, we have some green.ch public IP address subnet, the P-2802 
is running as (br-)router, smaller installations PPPoE is

terminated on the ZyWALL.

As wholesales VDSL2 is PPPoE only, there is no advantage in terminating 
the tunnel direct on the router as in the ADSL times using

PPPoA then.

Please contact me off-list for some more in-depth P-2802 information.

Regards,

-Kurt.

The status of port is showtime
Link type: VDSL2
Bearer1 downstream rate: 27536 kbps
Bearer1 upstream rate: 11040 kbps

So before getting an Alix board, you suggest I should first
ask Swisscom (via Green) to reduce the rate? 

Regards & thanks for your feedback!
Olivier

You should have a look at the two following values too:

- Downstream attainable payload rate:
- Downstream attainable line rate:

They show the maximum possible transfer rate at the time of the DSL
sync. Since a fluctuation of a few MBit/s can be normal for various
reasons, your effective downstream rate should be noticeably lower
than those maximum values. If the
margin is too small, this might indicate that you could get a more
stable sync using a lower fixed rate (like 20 mbit/s).

My two lines had to be fixed at 8 MBit/s each to get a stable sync,
but they are rock solid (although my usage involves more traffic than
multiple connections).

However if a sync issue is the reason for your disconnects, they will
show up in your routers logs. If the line stays synced when the
timeouts start to appear, the problem might be with your provider or
as you suspected, with the P2802.

regards

Flavio
