You do not need to disconnect. Data resumes all by itself. TX/RX activity COMPLETELY stops, then suddenly resumes. Cannot ping anywhere, not even the TC ethernet port. Then it comes back to life. It *seems* to happen most when the initial connect speed is "low" (below 44K or so), perhaps contributing to the retraining theory (the slower connection may indicate more noise present, which would leads to retrains). Never been actually cut-off as a result of this, but sometimes it is so frustrating, that you are forced to disconnect and redial. Then, it may be fine for hours. Weird.
Krish - this seems to be a lot like the issue we're having with cambcity... Please talk to Sanjay / Tom Cwikala about it. All of the sudden, routing stops. The problem is, in our case, however, that routing stops all together and it doesn't recover. It just so happens that the customer equip. is a Bay Networks Instant Internet 400 though and they can't route at all once it stops dead like that - no recovery. I don't have the case numbers in front of me (sorry). Kevin

on for close to a minute. Seems a little long for retraining. Haven't investigated it further.
So in your case are you saying that - > data stops for some time and then you get back the data transfer? or are you saying that - data stops. have to dial again to recheck mail.
please clarify

Krish,
We are running the 4.1.59-6 on the HiperArc and 2.0.81 on the DSPs.
the
quads are using the 6.x.x code!

We are seeing times when a user is connected and all of a sudden they loose the ability to navigate or pull email... The
connection is
stil up, but it appears that no data is being TX/RX? Is there something in the DSP/quads that can cause this timeout? Is this a function of MTU/MSS? Or is it the fact that the HIPER ARC can't keep up with the requests? Well need to know the exact versions of hiper arc and DSP code to start.
krish
Would routing protocols help this? Right now we run a network
on a
single class C with 180 dialup IPs in the modem pools. 3 HUB, two run quads, the othe has 3 DSPs all running HARCs and latest TC3.6 code.
We are starting to get a lot of TIMEOUTS, the connection is never dropped, but the modem quits responding for a time. If left alone it will come back to life.
Anyone have any ideas? Thanks in advance!
