Figure 13. WAN Port 2 - Configuring the bridged PPP link
After completing this configuration, click on the
“Edit ’PPP’”
link to see if the link status. A proper configura-
tion and E1 link to WAN Port 2 should yield a valid bridged PPP link. In
figure 14
the Summary states “open
for MAC” followed by the number of sent and received octets. Due to being a bridged PPP link, the link is not
“open for IP”, but “open for MAC”, the unit of encapsulation for bridges. The link has fully connected.

Test the connection
1.
The first tests of the PPP connections are for successful pings to the IP address of WAN Port 1’s IP address.
Since the bridged PPP connection does not have a uniquely assigned IP address, the test is to ping the IP
address on the remote end of the bridged PPP connection.
2.
If the ping fails, the first check is with the physical layer. If the physical layer is not operating correctly,
there is no hope of layer two protocols (PPP) to function.
– Verify that the E1 links are operating properly with no alarms or errors. If there are alarms or errors, they
must be resolved before any success can be expected for the PPP links.
