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.
Error Log Entries and Test to Clear Values
1. Where P is the port network number (1 for PPN only); C is the carrier designation (for example, 
A or B for processor complex circuit packs); and S is the address of the slot in the carrier 
where the circuit pack is located (for example, 1 or 2 for either the first or second Processor 
Interface circuit packs).
