Example 1

A MX-ONE Service Node with only one route to another MX-ONE Service Node. The external line can convey calling and connected number. It is also possible to send TON together with the number.

The two exchanges use a closed numbering plan (that is, no conflicting directory numbers). The first digit of the cooperating exchange directory number series is used as route access code.

Public numbers and TON are not relevant, since this is only within the own private network and the private number has priority over the public number regarding the display.
