Glossary

IX
Term
Definition
Point-to-
Multipoint
Protocol
Defined in RFC 2178, which specifies that data that originates from a central
network element can be received by all other network elements, but data that
originates from a non-central network element can be received by only the
central network element. See http://www.faqs.org/rfcs/rfc2178.html. Also
referenced as PMP.
PPPoE
Point to Point Protocol over Ethernet. Supported on SMs 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.
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.
Red Hat
A registered trademark of Red Hat, Inc.
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.
Registrations MIB
Management Information Base file that defines registrations for global items
such as product identities and product components. See also Management
Information Base.
RetransLimitExp
Field
This field displays how many times the retransmit limit has expired.
