A table that stores information about possible destinations for packets being routed
through the HotWire DSLAM and identifies the next hop address to which to send the
packet.
Remote Termination Unit. A device, such as the HotWire 5446 RTU, that is installed at the
end-user site (or customer premises). The RTU connects to the local loop to provide
high-speed Internet or Intranet connectivity to the HotWire DSLAM.
Interface name of the card’s interface to the DSLAM system backplane bus.
Interface name of a DSL card’s DSL port #1.
Interface name of a DSL card’s DSL port #2.
Interface name of a DSL card’s DSL port #3.
Interface name of a DSL card’s DSL port #4.
The service subscriber is the user (or set of users) that has contracted to receive
networking services (e.g., Intranet access, remote LAN access) from one or more Network
Service Providers (NSPs).
Simple Network Management Protocol. An application-level protocol used in network
management.
An application level program typically running on a host system which facilitates
communication to an NMS manager.
See
NMS.
A notification message to the SNMP manager when an unusual event occurs on a network
device, such as a reinitialization.
A security feature for preventing end-user system to end-user system routing when the
end-user systems are attached to LANs on different RTUs (that are attached to the same
DSL card). That is, sourced-based routing can ensure that all upstream traffic within a
customer domain is sent to the ISP.
A permanent entry into the routing table that is manually entered.
A bit mask used to select bits from an IP address for subnet addressing. The mask is
32 bits long and selects the network portion of the IP address and one or more bits of the
local portion.
Transmission Control Protocol. The TCP/IP standard transport level protocol that provides
the reliable, full-duplex, stream service on which many application protocols depend.
A simple remote terminal protocol that is part of the Transmission Control Protocol/Internet
Protocol (TCP/IP) protocol suite. Telnet allows the user of one host computer to log into a
remote host computer, and interact as a normal terminal user for that host.
Trivial File Transfer Protocol.
A program that prints the path to a destination.
Virtual Local Area Network.
A layer 2 networking device.
Wide Area Network.
Wide Area Network Concentrator. The WAN-C concentrates data traffic from one or more
DSLAMs onto facilities providing access to the WAN. The WAN-C can be either a router (a
layer 3 networking device) or a VLAN switch (a layer 2 networking device).
A wiring center is usually a local serving office where the DSLs from the service
subscribers are terminated on the HotWire DSLAM.
