So, breaking down my traceroute, can I assume I'm looking at:

Oui?

You would have to as ranger or TelkomZA where hops 3-4 are physically located to be 100% certain but that could be right except hop two is your routers interface on the wan side.

Doh - of course. Not thinking. Taa.
 
Router LAN port---192.168.1.1

Router WAN/ADSL port---ti-224-4-01.telkomadsl.co.za [105.224.4.1]

ti-226-0-246.telkomadsl.co.za [105.226.0.246]---What happens next depends on whether you have a old DSLAM using ATM to the ESR ('Multiplexing' the circuits) or a newer Ethernet/IP-DSLAM that can actually pass the IP traffic on to the ESR

D-Link dsl-2750u reports thus:

Mode: ADSL_G.dmt

Type: ATM

Status: Up

Downstream Upstream
Line Coding(Trellis): On On
SNR Margin (dB): 221 120
Attenuation (dB): 195 125
Output Power (dBm): 51 22
Attainable Rate (Kbps): 12064 1148
Rate (Kbps): 4096 512
D (interleaver depth): 1 1
Delay (msec): 0.13 0.25
 
My understanding is that if the DSLAM uses ATM for it's backhaul to the ESR you have a PVC between the DSLAM & ESR and all the PPP sessions then terminate on the ESR. This type of DSLAM works at Layer 2.

If it's a IP based DSLAM you have IP-IP coms between the DSLAM & ESR.
This type of DSLAM would work at Layer 3 as it has some routing functionalities built in.

Hopefully ranger comes along and elaborates more on how the termination between DSLAM & ESR works.

Sounds correct, though. Seems we both need a refresher course with all this new technology being installed! :o

Thanks. In the meantime you have condemned me to a couple of hours on wikipedia... :D

DSLAM - Where all are adsl lines terminate
ESR - Edge Services Router, which the DSLAMs connect to (as well as other services)
ATM - Asynchronous Transfer Mode
PVC - Permanent Virtual Circuit, used by ATM, think of it as a fat pipe all the PPP sessions get carried in.
IP- Internet Protocol, IP-IP basically just means two devices communicate via IP

Wikipedia would be a good start for an overview, if you want to get down to frame,cell, packet level stuff etc just ask and I'll point you in the right direction :D

Mentor me oh great one :). You not far from Stanger :D.

CC me too
 
Come 5pm I get timeout on the second hop (first one after the router) - google services are not accessible when this happens. Everything else seems to work but super slow. What course of action to take? Log a fault? Been like this since yesterday (that I'm aware of).

MickeyD, Ponder: Thanks.

Now leave me alone, I have lots of reading to do. :)
