Direct Dialing In (DDI)
Description Provides an automatic direction of an incoming ISDN S0 line call
to a specific extension. This requires a DDI number informed from
the ISDN network. The DDI number is converted to a specific
extension number by using a pre-programmed conversion table.
Explanation
1. An incoming call from the ISDN network reaches your DSHS
(Digital Super Hybrid System).
The ISDN network informs DSHS of the DDI number.
2. DSHS converts the DDI number to an extension number and
directs the call to the extension.
Conditions • The DDI service can be enabled or disabled on a CO line basis.
• After the extension number is determined, the system operates the call
in the same way as the DIL 1:1 operation.
• If a DDI number cannot be converted to an extension number, the call is
put to IRNA destination.
