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
1 Check that the LED indicators on the BCM50 Chassis and the MBM are solid green.
2 Using an analog test set, verify that a dial tone is present at the MBM termination point.
