SWITCH ALARM: MODEM COMMS
PROBLEM, POSITION 2
There is a fault. There is a problem with the I/O communications with Traffic Modem. The front
panel LED “Unit Status” will be RED.
Suggestions:
•
Check Cable Connections – refer to Chapter 4. CABLES AND CONNECTIONS.
•
Check Modem Configurations – refer to Chapter 5. MODEM, RMI/TMI, AND
SWITCH CONFIGURATION.
SWITCH ALARM: TMI:I/F
MISMATCH, POSITION 2
There is a fault. There is a mismatch of data interface type between what has been selected in the
modem menu and the TMI type that is connected to that Traffic Modem. The front panel LED
“Unit Status” will be RED.
Suggestion: Ensure the modem interface type is compatible with the TMI being used. The
CDM-600s have both TX and RX interface types. The CDM-570s just have one unit interface
type. Either edit the modem interface setting(s) or swap the TMI.
