Features and Specifications Manual
Uniform Numbering Network allows multiple or compatible systems to be
connected in a network using Tie lines. A Station user can dial a system
number and a station number (open numbering) or dial the station number
only (closed numbering) to access any station. When the calling and called
systems are not directly connected, several Tie lines may be accessed to
route the call. Each system extends the call to the next system until the final
destination is reached.
