Serial Channel Local Loop-Around Test (#229)
This test checks TN775D on-board circuitry associated with the serial links to the
Expansion Interface circuit packs. A request is sent to the PN’s Maintenance
circuit pack over the active link via the active Expansion Interface circuit pack
serial interface circuitry to test the serial interface circuitry of the standby
Expansion Interface circuit pack link. If a response is received, then by definition
the serial interface circuitry associated with the active link is good.
The PN’s Maintenance circuit pack has 3 separate serial interfaces, one to each
of the following:
■
Management terminal which is tested by Test #228
■
Active EI circuit pack which is tested by Test #229
■
Standby EI circuit pack which is tested by Test #229
Table 8-408.
