Point-to-Point
Protocol
The Point-to-Point Protocol, defined in
, provides a method for
transmitting packets over serial point-to-point links. There are many other
RFCs which define extensions to the basic protocol.
PPPoE
Point to Point Protocol over Ethernet. Supported on BHS for
operators who use PPPoE in other parts of their network
operators who want to deploy PPPoE to realize per-subscriber
authentication, metrics, and usage control.
PPS
Packet Per Second
PPTP
Point to Point Tunneling Protocol. One of several virtual private
network implementations. Regardless of whether the Network
Address Translation (NAT) feature enabled, Subscriber Modules
support VPNs that are based on this protocol.
Protective Earth
Connection to earth (which has a charge of 0 volts). Also known as
ground.
Proxy Server
Network computer that isolates another from the Internet. The
proxy server communicates for the other computer, and sends
replies to only the appropriate computer, which has an IP address
that is not unique or not registered.
PTMP
See Point-to-Multipoint Protocol.
Quick Start
Interface page that requires minimal configuration for initial
module operation.
Radio Signal
Strength
Indicator
Relative measure of the strength of a received signal. An
acceptable link displays an Radio Signal Strength Indicator (RSSI)
value of greater than 700.
Recharging
Resumed accumulation of data in available data space (buckets).
See Buckets.
Reflection
Change of direction and reduction of amplitude of a signal that
encounters an object larger than the wavelength. Reflection may
cause an additional copy of the wavelength to arrive after the
original, unobstructed wavelength arrives. This causes partial
cancellation of the signal and may render the link unacceptable.
However, in some instances where the direct signal cannot be
received, the reflected copy may be received and render an
otherwise unacceptable link acceptable.
Region Code
A parameter that offers multiple fixed selections, each of which
automatically implements frequency band range restrictions for
the selected region. Units shipped to regions other than the United
States must be configured with the corresponding Region Code to
comply with local regulatory requirements.
