Network Time Protocol.
Non-Volatile RAM.
A proprietary network management program used with HP OpenView that helps a network
administrator manage SNMP devices.
A group of control and data characters that are switched as a unit within a communications
network.
Protocol Data Unit. A message containing protocol-specific information.
Packet InterNet Groper. Used for testing and debugging networks, PING sends an echo
packet to the specified host, waits for a response, then reports the results of its operation.
Used as a verb, to PING means to use the program to verify the accessibility of a device.
The PING program is supported from both the DSL and MCC cards.
Plain Old Telephone Service. Standard telephone service over the PSTN with an analog
bandwidth of less than 4 Hz.
A device that filters out the DSL signal and allows the POTS frequencies to pass through.
Point-to-Point Protocol. as specified by Internet RFC 1661.
Proxy Address Resolution Protocol (ARP). A technique for using a single IP address for
multiple networks. A device responds to ARP requests with its own physical address, then
routes packets to the proper recipients.
Public Switched Telephone Network. A network shared among many users who can use
telephones to establish connections between two points. Also know as dial network.
Rate Adaptive Digital Subscriber Line. A technique for the use of an existing twisted-pair
line that permits simultaneous POTS and high-speed data communication at adaptive
symmetric and asymmetric rates.
The ability to automatically adapt when the port speed is lower than the line speed.
A device that connects LANs by dynamically routing data according to destination and
available routes.
A table used by a node to route traffic to another node in the multiplexer network.
