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

1Check that the LED indicators on the BCM450 Chassis and the MBM are solid green.

2Using an analog test set, verify that a dial tone is present at the MBM termination point.

3From the Element Manager, select Configuration > System > Keycodes to view the list of installed features.

4Verify that the appropriate keycode is active. For analog trunk modules, the keycode is Exp Port.

5Select Configuration > Resources > Telephony Resources and select the appropriate trunk. Verify that the trunk is active.
