The Excess Collisions on the LAN alarm indicates that too many collisions are occurring between data packets

network management LAN is the data network connecting the workstation running the CTC software to the
control card. The problem causing the alarm is external to the ONS system.
Troubleshoot the network management LAN connected to the control card for excess collisions. You might
need to contact the system administrator of the network management LAN to accomplish the following steps.
