Health and Status Messages
Type
Message
Indicates
Major
Device Failure
A device/self test has failed. The probable cause is a modem hardware problem
or diagnostic memory failure.
Facility Fault
A severe data transport problem is occurring due to poor line conditions. No
signal or a very poor signal is being received.
Streaming DTE
The modem is in an antistreaming condition. The RTS input to the modem was
held ON for a period exceeding the time selected by the RTS Antistream
configuration option. (Refer to the
DTE Interface section in Chapter 4 for a
description of the RTS Antistream configuration option.)
Access Security
A dial access security alarm is active. (Refer to the
Security section of this table
for dial access security conditions.)
Minor
VF Threshold
One or more of the analog parameter thresholds have been exceeded. The
probable cause is poor line conditions or improper threshold settings.
Thresholds may be set through the DCP or NMS commands.
DTE Alarm
One or more of the DTE signals on one or more of the DTE ports are in alarm
mode. (Refer to the
Port 1, 2, 3, 4 section of this table for DTE alarm
conditions.)
Rate Fallback
Due to poor line conditions, the modem’s transmit rate is below the configured
rate. (Refer to the
Leased Line and Dial Line sections in Chapter 4 for a
description of configuration options affecting rate.)
