One of a device’s operational states that indicates the device’s dial line is currently
connected for voice transmission.
Transmission Control Protocol/Internet Protocol. The dominant protocol suite in the
worldwide Internet, TCP allows a process on one machine to send data to a process on
another machine using the IP. TCP can be used as a full-duplex or one-way simplex
connection.
Time Division Multiplexer. A device that enables the simultaneous transmission of multiple
independent data streams into a single high-speed data stream by simultaneously
sampling the independent data streams and combining these samples to form the
high-speed stream.
No reply from TDM or MCMP circuit card. The DSU periodically polls the TDM or MCMP
circuit card for health and status. When the DSU does not receive a response from the
TDM or MCMP, this message appears in the Health and Status report.
A condition indicating the device is currently in test mode, such as local loopback.
The time and date a device reported an alert to NMS.
Test Mode. An EIA lead standard for V.24 circuit TM, ITU 142; an output signal
(DCE-to-DTE).
A notification message to the SNMP manager when an unusual event occurs on a network
device, such as a reinitialization.
A device that receives commands from other devices in the network.
This indicates that the control DSU has not received a health and status update from the
tributary DSU within the specified time.
A site or device configured within NMS that does not have sufficient information for the
system to automatically locate the device on the Network Map.
A device not directly supported by NMS for purposes of alert notification and network
access. Specifically, unmanaged devices’ alerts cannot be interpreted by the NMS and the
NMS cannot directly access the device’s tests and commands without using the
cut-through software.
A file you create to hold a specific configuration of device options. The purpose of this file
is to record device options you can send to multiple devices. Device option information
recorded within a user file is model specific and can be applied to any device of the same
model type.
A unique number, created by your system, associated with each user name on a server
system.
Voice Frequency. The part of the audio frequency range used to transmit voice sound
(usually 300 Hz to 3400 Hz). This band is used by the modem for its modulated signal.
A type of voice frequency line distortion, such as receive level or frequency offset.
Voice Frequency Threshold. The set of programmable parameters used to define
acceptable ranges (thresholds) of voice frequency channel characteristics. An alarm
generates when a measured voice frequency channel characteristic is outside the
acceptable range defined by the threshold(s).
A notification that a measured voice frequency channel characteristic is outside the
acceptable range defined by the threshold(s).
