Figure 1-16. Fields of the TRSS Information in the MSA
This figure shows the breakdown of the token-ring information fields in line 4
(CCU A) or 7 (CCU B).
TRA number (1, 2, 5 or 6). Indicates that the TRA has been selected (TRS or
TID function).
TRA mode, updated after TRA selection (option 1 in the TRSS function selection
screen, page 5-5).
Note: If field F indicates CCU INTERRUPTS DISABLED, the TRA mode has no
meaning.
The possible modes are:
CONNECT:
The TRA is operational and is under NCP control. The control
program handles all interrupts (except if there is an MIOH
error).
The PIO disable and the disconnect bits in the TRM level 1
error status are OFF.
DISCONNECT: The TRA does not run under the control of the control program
but under the control of the MOSS microcode. MOSS handles
all interrupts and PIOs to/from the TIC.
The PIC disable and the disconnect bits in the TRM level 1
error status are OFF.
