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 are in alarm mode. (Refer to the Port 1
section of this table for Port 1 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.)
Status Subtree Truncate Downstream health and status information has been truncated because
it overflowed system limits. There is a large amount of health and status
information in the subnetwork. This information can be recovered by
sending device health and status commands to specific modems.
Test Mode The modem or an upstream device is running a disruptive test.
Disabled The modem’s DTE port has been disabled.
On Dial Backup The modem is operating in Dial Backup mode.
FW Downloading A firmware download is in progress.
On Lease Backup The modem is operating in Lease Backup mode. This status occurs
only if the Dual Lease Line is enabled.
Primary Line Bad The modem is currently operating on the 2-wire backup facility, the
Lease Lookback option is enabled, and the modem does not detect
continuity on the primary 4-wire leased lines.
Backup Line
Good
The modem is currently operating on the primary 4-wire leased facility
with 2-wire leased lines selected as the backup facility, the Backup Line
Check option is enabled, and the modem detects continuity on the
2-wire backup leased lines.
Data Blocked The modem’s primary data path is blocked.
PSTN Test Fail The modem failed either the Dial Tone Detection or the Ring Tone
Detection portion of the Call Test command.
