Event 2 LINE DISCONNECTION (ABNORMAL)
LINE DISCONNECTION (ABNORMAL)
Description: An unexpected line disconnection has occurred. These abnormal line
disconnections typically occur on direct connect lines that are not usually
disconnected for any reason. Telcon generates this CENLOG.
Action: Check applicable line hardware and repair or replace as necessary. These
checks should include the line cable connection to the DCP, the line cable itself, the
modem, direct connect module (DCM) or terminal (if the terminal is direct connect),
and all other intermediate hardware between the DCP and the source of the data-setready
(DSR) signal.
