Trunk-side Layer 1 Query Test (#1242)
PASS The ICSU Status LEDs test executed successfully. A PASS result,
however, does not necessarily mean that the status LEDs behaved
properly. It only means that the software successfully attempted to light
the status LEDs. This is a visual test.
1. Visually exam the behavior of the LEDs while the test is running. The
LEDs are functioning properly if the four status LEDs are lit red for 5
seconds, then lit green for 5 seconds, then lit yellow for 5 seconds. If
the LEDs behave differently, replace the circuit pack at the
customer’s convenience.

This test determines the state of the transmission facility of a BRI port at the Layer 1 (L1)
physical layer: Activated, Pending Activation, or Deactivated.
The Activated state is the correct state for an ISDN-BRI port. In this state, the L1 interface can
send and receive synchronized signals. This test passes if the state of L1 is Activated. This test
also passes if software has taken this port out of service. See the description of the L1
“Deactivated State” below for more details.
The Pending Activation state indicates a problem with the channels, the wiring, or the TBRI-BD
circuit pack. When in this state, the Level 1 interface is either not receiving any L1 framing from
the channel or it is communicating with the channel but cannot transition to the Activated state.
The Deactivated state indicates a problem with the TBRI-BD circuit pack. When in this state, the
Level 1 interface is not active, an idle signal is transmitted to the channels, or that Layer 1 was
deactivated by the switch. When a TBRI-PT port is placed in the out-of-service state, Level 1 is
also put into the Deactivated state. This could be due either to the system detecting a fault with
the port or to a busyout port location request.
This test is run on TBRI-PT (ISDN Trunk-Side BRI Port).
