Data Terminal Equipment. The equipment, such as a computer or terminal, that provides
data in the form of digital signals for transmission.
A message signifying that one or more of the DTE signals is in alarm mode.
The signals associated with Data Terminal Equipment (DTE) communications to a device.
Examples: Clear-to-Send, Data Terminal Ready.
Dual-Tone Multi-Frequency. A signaling method using two voice frequencies to designate
the tones used for touch-tone dialing, as distinguished from pulse dialing.
Data Terminal Ready. A signal from the DTE to the modem, sent via Pin 20 of the
EIA-232 interface (V.24 circuit 108/1, /2), that indicates the DTE is turned ON and
connected to the modem.
The minimum number of seconds a condition exists before NMS reports it as an alert. The
range of values is from 5 to 300 seconds.
Error Correction. Common error-correction protocols are V.42, MNP4, MNP 10, and ETC.
A temporary work area used to view and change configuration options from the DCP
without impacting modem operation.
Electronic Industries Association. This organization provides standards for the data
communications industry to ensure uniformity of interface between DTEs and DCEs.
A pattern test run on local and remote devices simultaneously.
MIB objects unique to a specific company’s devices.
Errored Seconds. A second with one or more ESF error events (one or more CRC6 error
events or OOFs).
An alert control option that is set to indicate whether or not you want the device(s) to report
a specific alert type.
An alert-control DSU feature in which the DSU detects a positive voltage on either Pin 23
or 19, triggering an alarm.
A leased or dial transmission line.
An alert that NMS displays indicating that the device has detected an abnormal condition
on the facility (line) that could cause data errors. The facility alarm only applies to leased
or Analog Private Line (APL) devices.
A rule or set of rules applied to a specific interface to indicate whether a packet can be
forwarded or discarded.
Software that has been temporarily or permanently loaded into read-only memory.
A condition indicating that the device is currently receiving download firmware or
transmitting firmware to a remote device.
All devices assigned to a hunt group have been connected for a specific time.
Devices grouped together and viewed as a unit via Hunt Group Monitor commands. These
commands allow viewing of the status of the devices in the group, acknowledging and
clearing of alerts, displaying of information about a particular hunt group or device, and
placing or removing a device from the busy state.
One of a dial line device’s operational states that indicates an installed device is not
currently in use.
The worldwide internetwork, which predominantly uses the TCP/IP protocol.
The status of the device in the network.
