Solution
1. Check all physical connections, making sure they are snug and
correctly placed.
2. Trace the call. See ''Call Tracing TCAP Messages'' on page 201
and perform the steps there.
3. Check links by using the ss7tool command.
See ''Monitoring SS7 Gateway'' on page 150 for a complete
discussion of this command.
a. First, use the ss7tool linkstat to verify the physical
connectivity of the NewNet card.
If the card shows out of service, load the SS7 drivers. See
''Configuring the SS7 Gateway'' on page 146.
b. Then, use
ss7tool l2trace
ss7tool l3trace
ss7tool sccptrace
to verify message level connectivity.
c. Use the ss7tool command with other arguments as necessary.
