Downstream Sync Rate
This is the rate at which your connection can download (receive) data on your
DSL line, in kilobits per second.
Upstream Sync Rate
This is the rate at which your connection can upload (send) data on your DSL
line, in kilobits per second.
Modulation
Method of regulating the DSL signal. DMT (Discrete MultiTone) allows connec-
tions to work better when certain radio transmitters are present.
Data Path
Type of path used by the device's processor.
Broadband IPv4 Address
The public IP address of your device, whether dynamically or statically
assigned.
Gateway IPv4 Address
Your ISP's gateway router IP address.
MAC Address
Your Gateway’s unique hardware address identifier.
Primary DNS
The IP Address of the Primary Domain Name Server.
Secondary DNS
The IP Address of the backup Domain Name Server, if available.
Primary DNS Name
The name of the Primary Domain Name Server.
Secondary DNS Name
The name of the backup Domain Name Server, if available.
MTU
Maximum Transmittable Unit before packets are broken into multiple packets.
IPv6
Status
May be
Enabled
or
Unavailable
.
Global Unicast IPv6
Address
The public IPv6 address of your device, whether dynamically or statically
assigned.
Border Relay IPv4
Address
The public IPv4 address of your device.
IPv4 Statistics
Transmit Packets
IPv4 packets transmitted.
Transmit Errors
Errors on IPv4 packets transmitted.
Transmit Discards
IPv4 packets dropped.
IPv6 Statistics
Transmit Packets
IPv6 packets transmitted.
Transmit Errors
Errors on IPv6 packets transmitted.
Transmit Discards

Downstream and Upstream Statistics
SN Margin (db)
Signal to noise margin, in decibels. Reflects the amount of unwanted “noise”
on the DSL line.
Line Attenuation
Amount of reduction in signal strength on the DSL line, in decibels.
Output Power (dBm)
Measure of power output in decibels (dB) referenced to one milliwatt (mW).
Errored Seconds
The number of uncorrected seconds after being down for seven consecutive
seconds.
Loss of Signal
The absence of any signal for any reason, such as a disconnected cable or
loss of power.
Loss of Frame
A signal is detected but cannot sync with signal caused by mismatched proto-
cols, wrong ISP connection configuration, or faulty cable.
FEC Errors
(Forwarded Error Correction errors) Count of received errored packets that
were fixed successfully with out a retry.
CRC Errors
Number of times data packets have had to be resent due to errors in transmis-
sion or reception.

Link: Configure
When you click the
Configure
link, the Broadband
Configure
screen appears. Here you can reconfigure your
type of broaband connection should it change in the future.
Broadband Connection Source
- dsl, ethernet, or auto (automatically detected).
Media
– Auto (the default self-sensing rate), 10M full- or half-duplex, 100M full- or half-duplex, or 1G full- or
half-duplex.
MDI-X
– Auto (the default self-sensing crossover setting), Off, or On.
The WAN connection is automatically configured. However, you can adjust the
Maximum allowable MTU
(Maximum Transmittable Unit) value, if your service provider suggests it. The default 1500 is the maximum
value, but some services require other values. 1492 is common.
If you make any change here, click the
Save
button.
