External Mute
When the IBUC operates as a single thread IBUC, Pin N of the M&C interface
connector functions as an external mute. If it is not connected (left open), then
transmission is not muted. When Pin N is connected to Pin F (chassis ground),
transmission is muted.
To re-enable transmission, remove the Pin N connection to Pin F. Transmission will
now resume.For more information about the M&C interface connector, see
.
Common Errors
LED is Red
A red LED indicates only that a fault (or alarm) has occurred and does not necessarily
indicate that transmission has stopped. A flashing red light indicates a minor alarm and
a solid red light indicates a major alarm. You can communicate with the IBUC to
determine what is causing the fault, and then clear the fault condition.

If the Power LED is off or not turning on at all, the IBUC is probably not receiving
power.
Restore power to the IBUC by
• If the IBUC is powered by the modem, verifying that the modem is working
properly.
• Checking that the modem is receiving power (that is, the modem power cord is
plugged in) and that DC power to the IBUC is enabled.
• Checking that all cable connections are solid.
• Checking that the power supply is functioning or that AC mains has the proper
voltage.
