T1/E1 Status LEDs

These LEDs apply to each individual T1 or E1. Various conditions are indicated by the state of

the LED (its color and whether it blinks, alternates color, or is on solid). The condition descrip-

tions vary depending on whether the LEDs represent T1s or E1s of the active controller card

or the controller card on standby. Table 2-6 provides LED definitions for the active and

standby cards.
