TCD-night COS

The command states to which trunk number category the extension belongs when the exchange is night-switched.

The trunk number category controls which numbers the extension can dial for outgoing calls.

Extensions (and trunk lines) can be divided into nine different trunk number categories.

Category 0 is open for all numbers

Categories 1-8 are digit controlled

By using command group 22 a number of routes (trunk numbers) can be opened for traffic. For each route it is determined whether one or more of trunk number categories 1-8 shall be opened for the route.

An extension procedure is used for day/night-switching of the exchange.
