"DESCRIPTION",
"\"This field is used to describe the minimum guaranteed rate for a VCL which is bound to this traffic descriptor for BAN ATM Trunk Cards. It is applicable only for RTVBR service category. Unlike switched voice calls in the TDM world we cannot oversubscribe bandwidth because all of our voice calls must be connected at all times so that we can receive signaling to tell us that the phone when off hook. Instead of oversubscribing we suggest that the service provide under provision their voice calls. An example of this would be a normal good quality voice call over ATM requires about 80kb of bandwidth. To share the bandwidth resource over several customers the service provider would instead allocate (for example) rate16K for a single voice channel, this would allow 5 channels to share the bandwidth required to connect a good quality voice call. Any value less than rate80K could be used if the service provider wished to share bandwidth resources over more than one voice call. In order for this method to produce a good quality voice call enough bandwidth must be unallocated and used in a shared pool by all connections. When the buffering is not adequate for a good quality call the connection will not terminate, instead the call quality will suffer. Values greater than rate80K would be used by devices like a PBX. For all service categories other than RTVBR, unused is the only valid value.For RTVBR unused is not a valid value and one of the rates has to be specified. This parameter is used independently for transmit and receive traffic based on the traffic descriptor specified for transmit and receive in the VCL. Changing this parameter may cause a trap if newly utilized bandwidth for a card exceeds its available bandwidth. It may happen on multiple cards and therefore there can be multiple traps.\"",
