Dialing Plan Overview
Depending upon the type of dialing plan used in the network (Coordinated
Dialing Plan [CDP], or Uniform Dialing Plan [UDP] or a combination of
both) the general idea is to have all calls that are terminating at a branch office
first dial a number that will get routed to the main office associated with that
branch office. The main office recognizes this number as belonging to the
branch office and appends a tandem prefix to this number using Digit
Manipulation Index (DMI). The main office then routes the call to the branch
office while accounting for the additional bandwidth used.
See Figure 18 for an example of a tandem call.
