This object specifies the UNI service attributes. service-Multiplexing : This bit specifies whether the UNI supports multiple EVCs. Point-to-Point EVCs and Multipoint-to-Multipoint EVCs may be multiplexed in any combination at the UNI if this bit is set to 1. bundling : This bit specifies whether the UNI has the bundling attribute configured. If this bit is set to 1, more than one CE-VLAN ID can map to a particular EVC at the UNI. allToOneBundling : This bit specifies whether the UNI has the all to one bundling attribute. If this bit is set to 1, all CE-VLAN IDs map to a single EVC at the UNI.But if it is set to 1 than serviceMultiplexing and bundling should be 0. To summarize the valid combinations of serviceMultiplexing(0), bundling(1) and allToOneBundling(2) bits for an UNI, consider the following diagram: VALID COMBINATIONS |UNI ATTRIBUTES | 1 | 2 | 3 | 4 | |Service | | | | | |Multiplexing | Y | Y | | | | | | | | | | | | | | | |Bundling | | Y | Y | | | | | | | | |All to One | | | | | |Bundling | | | | Y | | | | | | | This object will take care of different service for example if you set all-in-bundling bit to 1 than serviceMultiplexing and bundling bits will set 0.
