Windows NT WAN NDIS Architecture developed by Microsoft for Network Adapters.
NDIS
Network Driver Interface Specification as developed by Microsoft.
NID
Network Interface Device
PAP
Password Authentication Protocol. Part of the PPP protocol to ensure authentication of
the connection between two devices.
PCI
Peripheral Component Interconnect. This is bus technology, referring to the slot where
the board connects to the computer.
PCR (Peak Cell Rate)
This is the maximum amount of cells/second transmitted over this connection. This is
determined by the minimum intercell spacing in seconds, which is the time interval
from the first bit of one cell to the first bit of the next cell.
PMD
Physical Media Dependent.
POTS
Plain Old Telephone Service.
PPP (Point to Point Protocol)
This is one of the various protocols for data transmission.
Protocol
A set of rules and procedures that govern the exchange of data between two
communicating systems.
PVC ( Permanent Virtual Circuit)
A PVC is a logical dedicated circuit between two user ports in point-to-point
configuration. This is referring to the connection from the computer to the Internet
Service Provider (ISP).
RAS
Remote Access Server
RFC 1483
This is a protocol for the connection. It is technically referred to as Multiprotocol
Encapsulation over ATM Adaption Layer 5.
RIP (Routing Information Protocol)
The protocol governing the exchange of routing information between IP routers.
SRAM
Static RAM
SCR (Sustainable Cell Rate)
The sustainable cell rate, in cells/second, at which cells are transmitted over this
connection (only applicable for VBR service). This is the maximum average rate for
cells that are sent in bursts at a peak rate.
