A now-obsolete read-only gauge that reported the total number of XOT (X.25) calls that were refused, since superseded by the Counter32-typed telProdNpMonInterfXotStateTotalCallRefusedCounter. When it was in use, this told an admin how many call attempts had been rejected, a useful indicator of capacity limits or configuration mismatches preventing X.25 calls from being accepted; admins should now rely on the counter version of this statistic instead. A device still exposing this obsolete gauge alongside a nonzero value would be signaling that some XOT calls have historically been refused, though new monitoring should reference the counter-typed replacement object.
