Expansion Interface Packet Interface Test (#589)
This test is nondestructive. This test attempts to send a data packet from the
TN1655 Packet Interface circuit p ack through any intervening Expan sion
Interface circuit p acks and/or Switch Node Inte rface circuit pac ks and through
the Expansion Interface circuit p ack to be tested. The path the data packet takes
is dependent on the loc ation of the Expansion Interface circ uit pack to be tested
and whether the system has dup licate Port Network Connectivity. The following
diagrams and short d iscussion of each desc ribe the different paths the test uses.
Figure 9-47. Expansion Interface Packet Interface Test—Packet Endpoint Loop
The path shown in Figure 9-47 is used when testing an EPN EI that is on the
active PNC.
Figure 9-48. Expansion Interface Packet Interface Test—PPN to EPN loop
In a Center Stage configuration the path shown in Figure 9-48 is used when
testing an EPN EI that is on the standby PNC. In a Direct Connect c onfiguration,
this path is used on any PPN EI or on an EPN EI that is on the standby PNC.
