Front Panel Indicators

The front panel of the system provides LED indicators for the alarm status of the transmit and the
receive T3 and the T2 interfaces (refer to Table 33-2 and Figure 33-2). Also on the front panel are
indications for power and for operating status (Fail/Active).
The Overflow LED indicates that the cell rate coming from the T3 interface exceeds the bandwidth of
the T2 facility and that the Interface Adapter buffer has overflowed.
