In the example in Figure 141, the calling party dialed a private number in the
UDP format: LOC+DN (656-4020). The originator's DN is 2020 and the
LOC is 338. If the call is routed all the way through the private network, the
user on DN 4020 sees H3382020 on the display. (The terminating node
inserts the letter H in front of the CLID digits to indicate that the call
originated from the private network.)
