Maxing a 100Mbps Ethernet port out, are we?

Hey Smith,

Side Note..you better charge that battery soon..

-TimJ

The battery timer is lying :P It's an extended runtime and it really has an hour left on it. It's all charged up though, just had a busy day with it.

Now that you have a 7550 to play with, see if you can...

1. Change the logon name to something other than "admin"

2. Clear the error counts without having to reboot the modem

-Thanks

I noticed it said Interleave... but I thought you were on FastPath? Maybe this isn't at your main place.

It's installed at another location on a Verizon Business line I tend to. That line if the stats hold like that can be boosted to 2200kbpos/640kbps and FastPath. The line in the past couldn't do any more than an unstable Interleaved 768kbps/128kbps until I got Verizon out to fix the copper and replaced all of the wiring in the building where that line is at.

Where exactly on the remote PC does the syslog server store the log? I have the check box enabled and the IP address of my main PC entered in. But I can't find the log anywhere. When I save a custom config, it saves onto the desktop.

What server software are you using? I'm pretty sure that is dependent on the configuration of it rather than the modem.

What was the line stat originally on that "golden oldie"?
I might have a few site(s) that a 7550 might help with (long loop lengths / etc)

Thanks.

With the SE567, the stats used to be:

DS.Atten. 54
US.Atten. 31.5
DS.Margin: Sync at 20dB, drop to 10dB and bounce between 10 and 17dB.
US Margin: Sits at 18dB
Downstream and upstream powers don't get reported correctly on the SE567.
Interleaved + G.DMT Mode.

The old Westell 2200 had similar stats to the SE567, but that modem I don't think reports the upstream correctly anymore as it's gotten so old. Might not even pull that info correctly from the DSLAM anymore.

Before getting the line fixed, the speed was half as fast, or a third as fast on the upload. Margins were anywhere between -3 to 10dB with constant drops. Upstream was often 18dB except for when the line crapped out and connection dropped. CRC errors were very common, and telephone noise was very common while DSL was up. The attenuation was also 10+dB higher on the downstream, reaching 70dB at times and upstream sometimes hit 50dB if I caught it at the right time.

The 7500 and 7550 I believe use the same chipset for the DSL Transceiver. The Westell 6100s (newer) I also believe use the same chipset. Seems they're set up in such a way to either ramp up transmit power for higher SNR (and perhaps induce more cross talk into the plant) or it's just a more efficient chipset.

Here is a question I have...
I have 3 sites with the new FTR 7500 (branded their logo etc)

None of them are reporting downstream power (0 dbm)

The 4th site is using an old Westell 7500..and it's showing downstream power. (each modem is coming off a different site)

Does the modem tell the DSLAM to ramp up the power? I can't wrap my head around it yet...

Would the 7550 fix the downstream power problem? (actually request the DSLAM to amp up a bit??)

-TimJ

A power of 0 is generally that statistic not being reported. Someone with access to the DSLAM can see that. The power is negotiated on sync and it seems to be based on the chips on both ends of the line, based on how they see the line conditions and negotiate a connection.

Not something I would be super concerned about if the lines are not seeing problems.

Sorry for the newb question... I got it figured out now

reply to Smith6612
Have you played around with the 'Up to 300 Mbps' vs. '300 Mbps only' setting?
