T1/E1 Status LEDs
These LEDs apply to each individual T1 or E1. Different conditions
are indicated by the state of the LED (its color and whether it
flashes, alternates color, or remains solid). The condition
descriptions vary depending on whether the LEDs represent T1s or
E1s of the active controller card or the controller card on standby.
Table 2-4 on page 2-16 provides LED definitions for the active and
standby cards.
