A.2 Testing Network Connectivity Using PVCs
The network connectivity tests require that two ATM adapters be connected
to an ATM switch fabric with PVCs (as shown in Figure A.2). The carrier
lights should be extinguished on the adapters and on the switch fabric, indi-
cating that the fibers are OK.
Figure A.2 - Hardware Configuration for Checking PVCs
The network connectivity test suite, shown in Figure A.3, examines higher
level functionality after basic adapter board performance has been verified by
passing all the tests and checks shown in Figure A.1.
