In an open numbering plan, each office in the K-CCIS network is assigned a
one-, two- or three-digit office code and each station in the office is assigned
telephone numbers from two to eight digits.
In the same office, a station-to-station call is made by dialing the telephone
number of the desired station.

connected per K-CCIS Network.
When a Closed Numbering plan is used the extensions in the network cannot
have the same prefix number.
