226 Operation
Chapter 4 - Operation and Administration
A ranges list of 21,42,63 means that packets with a priority from 0 to 21 will be
transmitted using the first QoS Profile defined in the Uplink QoS Profiles list (see
below), packets with a priority from 22 to 42 will be transmitted using the second
QoS Profile defined in the Uplink QoS Profiles list and packets with a priority
higher than 42 (43 63) will be transmitted using the third Uplink QoS Profile.
A ranges list that includes a single entry (63 for DSCP and 7 for 802.1p) means
that priority based classification is not used.
4.11.4.6.4 Uplink QoS Profiles
The Uplink QoS Profiles parameter enables to define up to four QoS Profiles,
where each entry is the QoS Profile associated with the applicable entry in the
Uplink Upper Priority Limits list. The list includes up to four QoS Profile Names,
where each name must be one of the names that exist in the database after being
defined using the QoS Profile menu. Each entry in the Uplink QoS Profiles list is
associated with the applicable entry in the Uplink Priority Ranges list.
4.11.4.6.5 Downlink Upper Priority Limits
The DownLink Upper Priority Limits list functionality is the same as that of the
Uplink Upper Priority Limits list, except that the ranges are defined for downlink
communication.
4.11.4.6.6 Downlink QoS Profiles
The Downlink QoS Profiles list functionality is the same as that of the Uplink QoS
Profiles list, except that the QoS Profiles are associated with the entries in the
Downlink Upper Priority Limits list.
4.11.4.6.7 Priority Classifier Class
A read-only parameter (available only in Show menu). Currently the Class of all
Priority Classifiers is Local.
4.11.4.7 QoS Profiles
The QoS Profile defines the Quality of Service parameters that are applicable when
the QoS Profile is used.
Different QoS Profile Types are available to support different service requirements:
Real-Time (RT) service is designed to meet the needs of Real Time Variable Bit
Rate like services characterized by requirements for guaranteed rate and delay
such as streaming video or audio. These services are dynamic in nature, but
offer periodic dedicated requests opportunities to meet real-time requirements.
Because the Subscriber Unit issues explicit requests, the protocol overhead
and latency is increased, but capacity is granted only according to the real
