5.2.4  
Direct inward dialing 
 
Implementing features, see also Manager E Direct Inward Dialing

Definition  
With direct inward dialing (DID), an incoming call can reach a station without intervention by the attendant console.
This feature is handled in call management. The internal and external numbering systems are defined in the numbering plan.
Public Networks require that DID calls to a station that is out of service, or is otherwise unreachable (for example, do not disturb) must be intercepted to a station, an answering position, or to an announcement device. It is therefore necessary to program intercept destinations for DID stations.
In HiPath 3000/5000 Manager E and Assistant T, the DID number corresponding to an internal call number can up to 11 digits in length.
For an incoming call on an ISDN PRI line, the PBX number is blanked out to the left of the incoming call number. The remaining portion of the call number is interpreted by the system as a DID number.
DID calls can appear on MUSAP keys. Refer to Section 5.2.5 "Selective seizure of a DID number via a MUSAP key".
