Example 1: Cannot dial out from an analog trunk
When you cannot dial out from an analog trunk, you may experience the following problems in
your network:
•
you are unable to reach a destination number when you dial it
•
there is no dial tone
•
instead of a dial tone, you hear a re-order or fast-busy tone
•
you hear a "wrong number" message from the central office.
Use the following procedure when you cannot dial out from an analog trunk.
Troubleshooting example 1

Using an analog test set, verify that a dial tone is present at the MBM termination point.

From the Element Manager, select Configuration > System > Keycodes to view the list of
installed features.
