Features and Specifications Manual
This feature allows multiple or compatible systems to be connected in a
network via Tie lines. Station users can access any station by dialling a
system number and a station number (open numbering) or by dialling the
station number only (closed numbering). If the calling and called systems
are not directly connected by a single Tie line, several Tie lines may be
accessed to route the call to the final destination. Each network system
automatically extends the call to the next system in line until the final
destination is reached.
