Universal night answer or trunk answer from any station is a night option. Incoming calls are routed to an analog port (e.g. for universal ringing). The trunk call can then be taken at any telephone by dialling a code.

Each port for "trunk answer from any station" is assigned a neutral night variant of the type "GENANS" by means of its administration number and the NAVAR AMO. Only one port of this kind is permissible for each night option. This neutral night option is then assigned to the ATND group as one of the night options 1-8.
