that the DPNSS/DASS link is working normally. This check assumes that
the PRI and DCHI are properly installed (for example, properly cabled)
and operational.
If the DPNSS/DASS status is not as shown in these steps, complete
the check and proceed to DPNSS/DASS fault-clearing procedures. For

The response is:
ENBL ACTIVE (The configured LAP protocols for each real and
virtual channel configured on the DPNSS1/DASS2 link are enabled.)
Procedure 53 "DPNSS/DASS (IDA) status check" (page 130)
128).
Action
Check the status LEDs on all PRI spans (1–8). For normal operation,
only the green ACT LED is lit.
Check the associated DCH LED (upper left, upper right, lower left, or
lower right). If the red LED is lit, the D-channel is disabled.
The DCH LED indicates the status of only one port associated with
one span (2, 4, 6, 8).
The red LED is lit only when this port is disabled.
The example in Figure 33 "IDA status check" (page 131)
the upper-left DCHI (associated with span 2) is enabled.
