2.7.66 CONTBUS-IO-A
A TCCA to Shelf A Slot Communication Failure alarm occurs when the active Slot 7 TCC2/TCC2P
(TCC A) has lost communication with another card in the shelf. The other card is identified by the Object
column in the CTC alarm window.
The CONTBUS-IO-A alarm can appear briefly when the ONS 15454 switches to the protect
TCC2/TCC2P. In the case of a TCC2/TCC2P protection switch, the alarm clears after the other cards
establish communication with the newly active TCC2/TCC2P. If the alarm persists, the problem lies with
the physical path of communication from the TCC2/TCC2P to the reporting card. The physical path of
communication includes the TCC2/TCC2P, the other card, and the backplane.
