high T(Transmit) Load

high R(Recieve) Load

upstream and downstream on UBR (Universal Broadband Router)

SNR (signal to noise Ratio)

DBMV (decibells per milli volt)

Generally VM faults are with the UBR's as they can not cope with the load being put on them, hence the hight TX and RX loads. and alot of the long standing outages are Low SNR on the UBR normally when SNR drops below 21 dbmv.

so the higher the speed of your internet ie 20 meg / 50 meg the greater the load on the UBR, hence the increase in hight tx and rx loads since upgrading customers speeds.

Yes CISCO etc etc is good and they do know what they are on about, but the Telewest network managed by Telewest engineers was far superior to NTL's. thats the point i was trying to make :-)

just as a last not, alot of the 1st line techies in Liverpool educated themselves to CCNA (Cisco certified Network Associate level) and had an excellent knowledge, so IBM wer gettin CISCO certified engineers for a mere 14k a year, LOL and now they have sacked most of them. and you get some high pitched underpaid offshore person who has a degreee in hanging up the phone.
