1. Run test board UUCSS.
o. Error Type 2561: Packet Interface Loop Around Test (598) Failure. The
ATM-TRK circuit pack has failed, the pac ket bus has a minor alarm active,
or the packet bus is out of service.
1. Run test board UUCSS.
p. Error Type 2817, 2818: DSP failure detected along the circ uit path.
1. Run test board UUCSS.
2. Follow the repair procedures suggested for Test #1293.
q. Error Type 3330: LANHO critical error. The circuit pac k reports that the
on-board LANHO chip is insane (possibly d ue to a problem in Packet Bus
arbitration, in the transmission line frame, or in the c ircuit pack itself). The
circuit pack c annot talk to the Packet Bus.
