MP.16 System Overview

configure Subscriber Station parameters locally on the SS by using one of the SS’s management interfaces (HTTP, CLI,
or SNMP). Configuration from the SS includes the following:
SS: Configure local SS information, such as the system name, location, up time, and the contact person’s email and
phone number.
Radio: Select the SS’s operating channel, channel bandwidth, and optionally configure a connection with a specific
BS.
Networking: Configure the SS’s Ethernet address/mask and default gateway.
Log: Set the parameters for the logging functions of the SS.
SS configuration parameters are discussed in their entirety in Subscriber Station Configuration.
Wireless Communication and Service Classes
Traffic is exchanged between the BS and SS through uplink connections (SS to BS) and downlink connections (BS to
SS). The MP.16 system supports Time Division Duplex (TDD) operation. In TDD operation, wireless transmissions are
divided into fixed-duration frames, with uplink and downlink subframes making up each frame.
In order to allow the administrator to efficiently define connections and their associated traffic types and QoS parameters,
the BS uses defined classes of service, called Subscriber Station Classes (SS Classes).
SS Classes, configured on the BS and provisioned to SSs in the network, determine how different types of traffic are
handled. As a packet is transmitted between the BS and SS, it is compared to a defined set of Packet Identification
Rules. Each rule contains classifiers against which the packet is matched; depending on which classifiers the packet
matches, it is directed to a particular uplink or downlink Service Flow. The Service Flow determines the QoS treatment for
each packet. Each SS Class contains at least one uplink and one downlink Service Flow (but as many as 16), each with
associated QoS settings. Up to 64 SS Classes can be created.
By using multiple SS Classes that include different SFs, a service provider can offer tiers of service to customers. A
“premium” plan, for instance, may consist of SS Classes offering SFs with improved QoS over a “standard” or “basic”
plan.
The MP.16 system comes supplied with pre-defined SS Classes, Service Flows, and PIRs. In addition, you can
customize the predefined SS Classes, Service Flows, and PIRs or create new ones that uniquely serve the needs of your
network environment.
Upon entering the network, an SS uses either the default SS class configured on the BS (under the Subscriber Station
Authentication tab) or a pre-assigned SS class (assigned by the BS under the Subscriber Station List tab or by a
configured RADIUS server).
See Service Class Creation for information on defining custom SS classes.
