ISDN service 

— Connected Party Display

The connected party is the party who answers the redirected call. 

a= CALLING ID    to    CALLED ID          R

The R indicates the reason for redirection. The CALLING ID and the 
CALLED ID may be the name or the number, depending on the 
information received from the far end.

Both terminal and attendant conference calls are identified as calls with “n” 
number of conferees. This display information generates locally and does not 
change the display on another switch. If the conference call eventually drops back 
to a two-party call, the original display information is restored. However, when 
two DCS and/or ISDN calls (or any possible combination of each) are 
conferenced and revert to a two-party call, the trunk group of the remaining call 
displays.

On ISDN calls to a hunt group extension, the caller’s display identifies either the 
name of the hunt group or the name of the group member who answers the call, 
depending on hunt group administration.

On ISDN calls to a TEG, the caller’s display identifies either the group or the 
group member who answers the call, depending on administration.

With CINFO you can use a vector collect digits step to retrieve caller entered 
digits (ced) and customer database-provided digits (cdpd) supplied by the network 
in an incoming call’s ISDN SET UP message. ISDN is required if the CINFO 
comes from the network.

The TCM used to pass on the originating facility’s FRL is sent by ISDN facilities 
in the SETUP message only if the trunk services type is tandem.

With II-digits you can make vector-routing decisions based on the type of the 
originating line. II-digits are provided for an incoming call by ISDN-PRI. It is a 
generally available ISDN AT&T Network service.
