How the system routes incoming DID trunk 
calls to the attendant group
Incoming DID calls route only to an extension. The LDN feature allows you to 
assign one or more extensions to an attendant group. The system uses the LDN 
extension, or extensions, to route calls to an attendant group.
How the system routes incoming FX and CO 
trunk calls to the attendant group
Incoming FX and CO trunks can terminate at an attendant group, although you 
administer your system to terminate the calls elsewhere. You can administer the 
system to terminate an incoming FX or CO trunk to one of the following:
Attendant group
Extension (This could be a VDN, an ACD split, a DDC group, a UCD 
group, a remote access extension, or any system extension.)
If you decide to terminate the call at the attendant group, the system treats the call 
as an LDN call
Considerations
The number of listed directory numbers that you can assign depends on your 
system’s configuration. See DEFINITY ECS System Description for capacity 
information. 
Interactions
Night Service
If you activate night-service capability and a night console is not assigned 
or is not operational, incoming LDN calls route as follows:
— DID LDN calls route to a designated DID LDN night extension. If 
no DID LDN night extension is designated, DID LDN calls route to 
the attendant.
— Incoming CO or FX trunk calls route to the night destination 
specified for the trunk group. If no night destination is specified for 
the trunk group, the calls route to the normal incoming destination 
for that trunk group.
— Internal calls and coverage calls to the attendant route to the DID 
LDN night extension during night service.
