Security
Association
SA
The set of security information base station and one or more of
its client subscribers share in order to support secure
communications. This shared information includes traffic
encryption keys and cipher block chaining initialization vectors.

Identifier
SAID
An identifier shared between base station and subscriber that
uniquely identifies a security association.
Service Class
-
Service classes are identifiers for a specific set of QoS parameter
set values. The use of service classes is optional. A service
identified by a service class is identical to a service that has the
same QoS parameter set explicitly specified.
identified by a service class is identical to a service that has the
same QoS parameter set explicitly specified.
The Service Class allows operators to configure service flows
directly on the RedMAX base station. Operators provision the
Subscribers with the Service Class Name; the implementation of
the name is configured at the RedMAX base station. This allows
operators to modify the implementation of a given service to local
circumstances without changing Subscriber provisioning.

operators to modify the implementation of a given service to local
circumstances without changing Subscriber provisioning.
This feature allows higher layer protocols to create a service flow
by its Service Class Name. For example, telephony signaling may
direct the subscriber to instantiate any available Provisioned
service flow of class G711.

Service Data
Unit
SDU
The data unit exchanged between two adjacent protocol layers.
On the downward direction, it is the data unit received from the
previous higher layer. On the upward direction, it is the data unit
sent to the next higher layer.

sent to the next higher layer.
Service Flow
Service flows are a key feature of the 802.16 standard. A service
flow represents a unidirectional data flow. Transmitting
bidirectional traffic requires that two service flows be defined: one
for the uplink, and another for the downlink. Each service flow
can be assigned a unique QoS settings.

Service Flow
Identifier
SFID
A 32-bit quantity that uniquely identifies a service flow to both the
subscriber and base station.
Service Flow
Name
-
An ASCII string that is used to reference a set of QoS settings
that (partially) define a service flow.
Service Level
Agreement
SLA
This describes in general the minimum quality of service the
provider is committed to provide

Management
Protocol
Protocol
SNMP
A network management protocol of the IETF.
SINADR
-
Signal to noise and distortion ratio.
Subscriber
SS
The RedMAX base station terminal configured as customer
premises equipment (CPE).
802.16 definition of a Subscriber.
Time division
duplex
TDD
A duplex scheme where uplink and downlink transmissions occur
at different times but share the same frequency.

Encryption Key
TEK
A key used to encrypt and/or decrypt data.
