■Temporary signaling connections are virtual packet-oriented D channel
connections used to exchange user-to-user information on DCS o ver ISDN
D channel and DCS AUDIX applications. Call-associated temporary
signaling connections permit information exchanges tha t are associated
with an existing B channel connection and noncall-a ssociated temporary
signaling connections allow this information exchange when no B channel
connection exists. A user may request a call-associ ated temporary
signaling connection either at call setup time or after the call has been
setup. A call-associated temporary signaling connect ion is cleared when
the associated B channel is cleared.
By combining AT&T’s public network services and ISDN features with ECS’s ISDN
and system features, you can differentiate your business from your com petitors’,
both in improved customer satisfaction and in greater operating effici ency. The
result is improved profits and reduced costs. Here is a brief glance at a few of the
possible ISDN applications:
■Combined incoming and outgoing call centers
■Dealer locator
■Sourcing
■Consumer-to business and business-to-business data retrieval
■Logging for callback
■Outgoing call management
Centralized Attendant Service
DEFINITY ECS owners who have more than one switch location can benefit
greatly by using the Centralized Attendant Service feature. Centralized Attendant
Service reduces the number of required attendants, and, in most cases, all those
attendants can be located at one of the switch locations, called “main.” Switches
at the other locations, called “branches,” redirect their ca lls to the Centralized
Attendant Service main. Thus, a company can have a centra lized attendant
group at the headquarters office and can handle calls from there for the bran ch
offices.
All locations in a Centralized Attendant Service arrang ement have a listed direc-
tory number. Calls to a branch listed directory number terminate at the main loca-
tion, even if the branch location has an attendant. These listed dire ctory number
calls are routed to the centralized attendant group over trunk circuits called
release-link trunks. These release link trunks ar e used only for centralized atten-
dant calls and signaling.
After a call is processed by the centralized attendant, it is extended back to the
branch location. The release link trunk is then dropped and made availabl e for
other calls to the centralized attendant.
