multiplexer
A device where several logical connections are combined into one
physical connection.
remote access node
RAN accepts a high concentration of data traffic from many DSLAMs.
It grooms the traffic to reduce the heavy processing load for backbone
routers which can limit the scalability of high-speed networks. RAN
receives cell- or frame-based end user traffic from the DSLAM and
sends the aggregated IP traffic to ISP backbone routers.

configuring M5122 locally.
telecommuter
A person who works at home with data communications to the central
office.
virtual channel
A communications channel which provides for the sequential uni-
directional transport of ATM cells.
virtual channel connection
A concatenation of virtual channel links that extends between the
points where the ATM service users access the ATM layer.
