Setting up trunk group night service
You can use trunk group night service if you want to direct individual trunk 
groups to night service. The system redirects calls from the trunk group to the 
group’s night service destination.
Trunk group night service overrides night station service. For example, let’s say 
you activate trunk group night service, and then your attendant activates night 
station service. In this case, calls to the trunk group use the trunk night service 
destination, rather than the station night service destination.
Instructions
Let’s direct night calls for trunk group 2 to extension 1245.
To set up trunk group night service:
1. Type change trunk-group 2 and press RETURN.
The Trunk Group screen appears.
2. Type 1245 in the Night Service field.
The destination can be a station extension, a recorded announcement 
extension, a vector directory number, a hunt group  ext ensi on, a t erminat ing 
extension group, or attd if you want to direct the call to the attendant.
3. Press ENTER to save your changes.
