SWITCH ALARM: MODEM COMMS
PROBLEM, POSITION 2
There is a fault. There is a problem with the I/O communications with Traffic Modem 2. The
“Unit Status” front panel LED will be RED.
Suggestions:
• Check cable connections – see Chapter 4. CABLES AND CONNECTIONS.
• Check modem configurations – see 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 “Unit Status”
front panel LED will be RED.
Suggestion: Ensure the modem interface type is compatible with the TMI being used. The
CDM-600/Ls and CDM-625/As have both TX and RX interface types. CDM-570/As and
CDM-570L/ALs have only one unit interface type each. Either edit the modem interface
setting(s) or swap the TMI.
