Glossary
A test pattern consisting of a one (1) followed by seven zeros (on the network only).
A 10-Mbps Ethernet LAN that works on twisted-pair wiring.
A rack-mounted device containing 17 slots in which to place circuit cards.
A product family and a registered trademark of Paradyne.
Alarm Cut-off command. A command for carrier-mounted CSUs that forces a deactivation
of the alarm relay on the 3000 Series Carrier.
Hardware that provides some transitional function between two or more devices.
A symbol (usually numeric) that identifies the interface attached to a network.
A software program housed within a device to provide SNMP functionality. Each agent
stores management information and responds to the manager’s request for this
information.
Alarm Indication Signal. An all ones signal transmitted to maintain transmission continuity
and to indicate to the receiving terminal that a transmission fault exists at either the
transmitting terminal or upstream of the transmitting signal. Sometimes referred to as Blue
Alarm.
Alternate Mark Inversion. A line coding technique used to accommodate the ones density
requirements of E1 or T1 lines.
American National Standards Institute. A member of ISO, ANSI accredits and implements
standards.
The use to which a device is put.
American Standard Code for Information Interchange. The standard for data transmission
over telephone lines. A 7-bit code establishes compatibility between data services. The
ASCII code consists of 32 control characters (nondisplayed) and 96 displayed characters.
A device that can be attached, either locally or remotely, to a DSU/CSU to display or print
alarm messages.
Data that is formatted so it is synchronized by a transmission start bit at the beginning of a
character and one or more stop bits at the end.
An SNMP trap that indicates that the device has received an SNMP protocol message that
has not been properly authenticated.
An 8-slot backplane that fits over one half of the open section of the 3000 Series Carrier.
This is a passive assembly that provides all interface connectors.
American Wire Gauge. An indication of wire size. The heavier the gauge, the lower the
AWG number, and the lower the impedance.
Bipolar 8 Zero Substitution. Encoding scheme for transmitting clear channel signals over a
T1 line.
The range of frequencies that can be passed by a transmission medium, or the range of
electrical frequencies a device is capable of handling.
