STPs are always deployed in pairs, allowing a spare should one of the STPs have a problem. Each STP of a "mated pair" are connected to each other via Cross links (C links). STP pairs connect to other STP pairs via Bridge or Diagonal links (B or D links). B links connect STP pairs that are at the same level of hierarchy while D links connect STP pairs that are different hierarchial levels. An example would be STPs in a local network connecting with STPs of a long distance network. Being at different hierarchies, the local-to-long distance links would be considered D links.
