Apart from obvious marketing ploys, the difference arises due to the baroque Russian dolls encapsulation stack used on ADSL (see the ADSL-based protocol stacks section in this document). A typical PPPoE connection runs IP over PPP (2 bytes) over PPPoE framing (6 bytes) over Ethernet framing (14 bytes) over RFC 1483 bridged connection (8 bytes) over ATM cells (5 byte overhead for every 48 bytes of payload). Every IP packet is thus burdened with 30 bytes of DSL protocol stack overhead plus 10.4% ATM cell tax. Assuming the average IP packet size in the Internet is around 500 bytes, the DSL protocol stack overhead is 6%, resulting in a total of over 16% of lost bandwidth just to accommodate the committees that constructed this monster.

Line Attenuation.

Line attention is in relation to the "loop loss" on your line.
The further you are away from the exchange the higher your attenuation figure will be as the signal loss increases.
The lower your attenuation figure the more chance you have of getting the faster speeds.

SNR (Signal to Noise Ratio).

The SNR margin can only be measured from your own property and therefore to be measured correctly may need an engineer visit to check this figure from the BT test socket behind your master phone socket.Your SNR figure can fluctuate on a day to day basis and may vary depending upon local equipment, conditions and interference.
An upgrade in speed often causes the SNR to decrease by up to 5 dB.The higher your SNR figure then the better your line quality and therefore a higher chance of getting faster speeds.

Line Length.

Ideally your line length should be below 3.5km from the exchange to get a 2Mb connection.
At the present time the general public has no way of checking themselves this figure.
However, you may be able to get an indication by using Sams checker.


Downstream Attenuation

0-43 dB - 2Mbps
43-60 dB - 1Mbps
> 60 dB - 512kbps

Downstream SNR

Should be at least 10 dB to get adsl - ideally above 12dB.
Anything less than this will see frequent disconnections and other problems.

Ja ne mogu pristupiti ovako modemu jer mi je modem u bridge modu tako da cu morati to rucno pogledati...

Kod mene je:
Power Down/Up(dBm) -6.5 / 0.0

Sve radi kako treba.
