Back at the house today, and here are the current line stats:

Upstream line rate (kbit/s): 1017
Downstream line rate (kbit/s): 13083
Upstream noise safety coefficient (dB): 6.1
Downstream noise safety coefficient (dB): 4.9
Upstream interleave depth: 1
Downstream interleave depth: 1
Line standard: VDSL2
Upstream line attenuation (dB): 10.9
Downstream line attenuation (dB): 31.2
Upstream output power (dBm): 0.4
Downstream output power (dBm): 8.8
Channel type: Fast
DSL up-time: 5 days 22 hours 25 minutes 11 seconds

So, overall considerably better than with the old wiring setup. over 10mbps gained in sync speed

Quite correct about the filters / splitters being straight through on the modem / DSL / data side.

It's something that irks me frequently when the only device attached to a line is a DSL router and when requesting support the helldesker insists that a filter must be in place for the router to work correctly. They tend to get even more confused when the line is run directly into a structured cabling cabinet.

In reply to a post by GeeTee:

helldesker

This word should be in the OED.

Edit: Sorry to bump a large old thread just for that.

Thanks for your confirmation.

For some time, I have wondered about the input/output side of the corresponding modems.

I opened up two last weekend - very difficult to see the connections onward from that socket; but the first item appears to be an Isolation Transformer in both.


Both had Surface-Mount components in the immediate vicinity.

One had an SM Capacitor and an SM Resistor, plus apparently a traditional Resistor.

The other had an SM Capacitor and three SM Resistors.


The specific type of component was determined by the Component Letter and Numbering systems, printed in white on the surface of the PCBs, eg C321 - Capacitor 321 (simple numbering).
