## 1003
TCD-day COS

The command states to which trunk call analysis category the trunk belongs when the exchange is day-switched.

(Command 1004 TCD-night COS is used to control to which trunk call analysis category the trunk belongs when the exchange is night-switched.)

The trunk call analysis controls which numbers the extension may dial for outging calls. In case of calls the trunk call category of the outgoing trunk controls which numbers the incoming trunk may dial.

Trunks (and extensions) can be divided into nine different trunk number categories. Category 0 is open for all numbers while the digits are checked for categories 1-8.

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