This feature facilitates Direct Inward Dialing into the private ISDN. The
Direct Inward Dial (DID) call will be treated as though the entire ISDN is a
large PBX.
DID calls entering the network at the local node (that is, the node on which
the destination set resides) are unaffected by the feature's operation. In this
case, treatment of the DID call is the same as with the stand-alone
configuration. The DID-to-Network Calling feature affects only those DID
calls which enter the network at a node other than the destination set's node.
Routing of the DID call across the ISDN will be the same as the routing of a
network call originated from within the network. (An additional information
element is sent with the call set-up message, to indicate that the network call
originated from a DID trunk.)
