If the test passes, move to step four.
If the test fails, a problem exists on this LAN segment.
Step 4:
Ping
IP-DSU
(1) from a device (e.g. router) on the same LAN segment as
IP-
DSU
(2).
If the test passes, move to step five.
If the test fails, a problem exists between the two LAN segments.
Step 5:
Ping
IP-DSU
(2) from a device (e.g. router) on the same LAN segment.
If the test passes, move to step six.
If the test fails, a problem exists on this LAN segment.
Step 6:
Ping
IP-DSU
(2) from a device (e.g. router) on the same LAN segment as
IP-
DSU
(1).
If the test passes, move to step seven.
If the test fails, a problem exists between the two LAN segments.
Step 7:
Set
IP-DSU
(2) in port loopback mode.
From BNS node (2) run a remote loopback test from the trunk module to
IP-DSU
(2).
If the test passes, go back to step one and test the circuit again.
If the test fails, check the facility between the two devices.
The preceding troubleshooting strategy should help you localize and remedy most of
your network problems. However, if problems are still unresolved after these
recommended troubleshooting procedures, contact your customer support.
