This object is a bit mask relevant only for 10G Muxponder entry. It contains a bit for each Muxponder service. To add a service the management should set the corresponding bit to 1. To remove a service the bit should be set to 0. For ODU allocation, the value of xpdrConnAddMask should be set to reflect the odus/time-slots provisioned for the service according to the following rules: a. For ODU1 the first byte is 0; for ODU0 the first byte is 1. b. The second byte. Is equal to: i. The 4 bits of the first nibble correspond to Uplink 1 allocated odus counted from right to left ii. The 4 bits of the second nibble correspond to Uplink 2 allocated odus counted from right to left c. The Third and Forth bytes keep bit-mask of the allocated time-slots within the odu.
