Chapter 8 – Configuring Frame Relay/PPP And DDS
Frame Relay And PPP Interface Statistics
Frame Relay And PPP Interface Statistics are as described in the Configuring Frame
Relay/PPP And T1/E1 chapter.
DDS Loopback
When at least one logical interface is configured and that interface is active, a DDS
Loopback test can be performed. This menu can be reached from a link on the DDS
WAN Interfaces menu.
The remote equipment must be able to loop, allowing the entire entire line to be
verified. If the remote equipment is another RuggedCom router, starting a line
loopback will verify both cards and the line. DDS has no standard for performing
digital loopback.
For more information on DDS loopback refer to the T1/E1 Loopback section in the
chapter “Configuring Frame Relay/PPP And T1/E1”.
Current Routes & Interface Table
The table provided by this command is as described in the Networking menu,
Network Utilities sub-menu. It is also provided here as a convenience.
Upgrading Software
For some customers, access to remote sites in accomplished solely by a DDS
connection. Usually a software upgrade will stop the system being upgraded,
perform the upgrade and then restart it. If DDS port was upgraded in this way, the
upgrade would fail as the DDS link was taken down. Instead, DDS software
upgrades modify only the software on the disk. You must schedule a reboot in order
to run the new version of DDS software.
