After obtaining a suitable VDSL router, and ensuring that the DSL filter is into the master socket*, the following settings should provide optimal performance on most routers:
| DSL modulation | VDSL2 (ITU G.993.2) | Auto |
| ANNEX mode | A/I/J/L/M |
| VDSL profile | 17a | 30a multi-mode |
| Rx AGC GAIN Adjustment | Enabled | Auto | Stable |
| Dynamic Line Adjustment (DLA) | Enabled | Auto |
| UPBO - Upstream Power Back Off | Auto | Enabled |
| ESNP - Enhanced Sudden Noise Protection | Stable | Auto | Enabled |
| SRA (Seamless Rate Adaptation) | Enabled | Auto |
| Bitswap | Enabled | Auto |
| G.INP (G.998.4) | Enabled | Auto (INP - Impluse Noise Protection - attempts to correct sudden bursts of noise) |
| G.vector (G.993.5) | Enabled | Auto (G.993.5 uses self-FEXT - far-end crosstalk- cancellation) |
| Non-standard G.vector (G.993.5) | Enabled | Auto |
| WAN transfer mode | VDSL (PTM) |
| WAN connection type (protocol) | PPPoE |
| 802.1Q | Enabled |
| VLAN ID | 101 |
| 802.1P | 0 (Older DLSAMs do may not understand 802.1P, however some newer Juniper DSLAMs will understand 802.1P, and allow a value of 2) |
| PPP authentication | Auto |
| PPP username & password | (Use broadband username+password provided) |
| IP address & gateway: | DHCP (auto-assigned; do not enter a static IP - they are consistently assigned using DHCP) |
| DNS servers: | 208.67.220.220 & 208.67.222.222 (Cisco, formerly OpenDNS) |
| NAT | Enabled |
| MTU | 1492 |
| IPv6 | (Not yet implemented) |
* DSL filter: do not plug the filter into a PSTN telephone extension. If the local network of computers is too far from the phone socket you should leave the DSL router connected direct to the phone socket and use Ethernet (LAN) cable FROM THE ROUTER, back to a switch near the local network computers. Ethernet cable will work up to 100m without performance loss, but VDSL signal degrades on PSTN cable after just 2m. PSTN telephone extension cables are not even "twisted pair" so they an extension cable will pick up interference from power supplies, lighting, and even the DSL router itself!
