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 5, Configure

Branch, 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.)

External Alarm A External input A to Port 4 of the modem is in an alarm condition.

External Alarm B External input B to Port 4 of the modem is in an alarm condition.

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 Multiport or Singleport Leased Line and Dial Line sections in

Chapter 5, Configure Branch, for a description of configuration options affecting

rate.)
