PI-PT (Processor Interface Port)
PI-PT is the physical port on the TN765 Processor Interface circuit pack. If the
Processor Interface Link (PI LINK) MO raises an alarm that can be correlated to
an on-board port problem, then PI-PT is alarmed. In a system without High or
Critical Reliability, there are no tests that run directly on Processor Interface port.
The PI-LINK MO is responsible for the testing of the TN765 ports along with DCS
links, AUDIX links, ISDN links, etc. Refer to the PI-LINK (Processor Interface Link)
Maintenance documentation for details. In a High or Critical Reliability system,
Processor Interface port is used to test the ports on the Standby Processor
Interface circuit packs. If the test fails, a Major alarm is raised. More importantly, if
a software requested SPE-interchange takes place and an alarm is raised on the
Processor Interface port, then the interchange may abort due to alarm severities.
