QoS class
A class of traffic for this connection.
• UBR  (Unspecified Bit Rate): The UBR service is used for 
applications that allow various delays and losses of packets. 
It is appropriate to use the UBR service for text/data/image 
transfer   applications,   as   well   as   messaging,   distribution, 
retrieval, and remote terminal applications.
• UBR   with   PCR  (Unspecified   Bit   Rate   with   Peak   Cell  
Rate): The UBR service is used for applications that allow 
various delays and losses of packets. The Peak Cell Rate is a 
determining factor in how often cells are sent in an effort to 
minimize   lag   or   jitter   caused   by   traffic   inconsistencies. 
When   you   select   this  value  from  the  drop-down   list,  the 
Peak cell rate field is displayed. Specify a required value 
(in cells per second).
