Fast Path
FEC Correction
There are two latency paths that may be used: fast
and interleaved. For either path, a forward error
correction (FEC) scheme is employed to ensure
higher data integrity. For maximum noise
immunity, an interleaver may be used to
supplement FEC.
Interleaved Path
FEC Correction
An interleaver is basically a buffer used to introduce
a delay, allowing for additional error correction
techniques to handle noise. Interleaving slows the
data flow and may not be optimal for real-time
signals such as video transmission.
Fast Path CRC
Error
The number of Fast Path Cyclic Redundancy Check
errors.
Interleaved Path
CRC Error
The number of Interleaved Path Cyclic
Redundancy Check errors.

Loss of Frame
Defect
Failures due to loss of frames.
Loss of Power
Defect
Failures due to loss of power.
Fast Path HEC Error
Fast Path Header Error Concealment errors.
Interleaved Path
HEC Error
Interleaved Path Header Error Concealment errors.

DDNS
Dynamic Domain Name Service (DDNS) provides users on the Internet
with a method to tie their domain name to a computer or server. DDNS
allows your domain name to follow your IP address automatically by
having your DNS records changed when your IP address changes.
This DNS feature is powered by DynDNS.org or NO-IP.com or
TZO.com. With a DDNS connection you can host your own web site,
email server, FTP site, and more at your own location even if you have a
dynamic IP address.

Tools
Use the Tools menu to ping, trace route, backup the current configuration,
restore a previously saved configuration, update firmware, and reset the
Barricade.
Ping Utility
This tool allows you to test your network connection. You can specify a
domain name or a valid IP address of the remote host for ping test.
•
Enter the address in the Destination address field, then click
Execute
.
The result will show in the Test Result area.

Trace Route Utility
Traceroute is a TCP/IP utility which allows the user to determine the route
packets take to reach a particular host.
•
Enter the information in the IP Address or Domain Name field, and
click the
Traceroute
button.
