This read-create Integer32 (0 to 32) reports or limits how many address maps in the hpnicfAtmDxiMapTable are associated with this particular PVC, given that one map can only belong to a single PVC but a PVC may have up to 32 maps. Admins use it to see how densely a PVC's address mappings are populated, which matters when planning how many peer IP-to-PVC bindings a single circuit can carry. For example, a PVC showing a map count of 32 has reached its maximum and cannot accept another hpnicfAtmDxiMapTable entry without removing an existing one.
