DCS Over ISDN-PRI D-channel
Enhances DCS by allowing access to the public network for DCS conne ctions
between DCS switch nodes. With this feature, DCS features are no longer
restricted to private facilities. The ISDN-PRI B-channel is us ed for voice commu-
nications, and the ISDN-PRI D-channel is used to transport DCS control in forma-
tion.
DCS Trunk Group Busy/Warning Indication
Provides attendants with a visual indication that the number of busy trunk s in a
remote group has reached an administered level. A visual i ndication is also pro-
vided when all trunks in a trunk group are busy.
DCS With Reroute
A sophisticated DCS rerouting capability for optimizing trunks. When you transfer
out of your AUDIX voice messaging system, for example, DEFINITY ECS sets up
a new path that optimizes system resources. Similar to the rerouting ca pabilities
used with Q-SIG.
Enhanced DCS
Enhanced DCS adds features to the existing DCS capabilities. Additional fea-
tures include:
■Exchanging information to provide class of restriction (COR) checking
between switches in the EDCS network
■Providing call-progress information for the attendant
■Allowing attendant intrusion between a main and a satellite
■Allowing a main PBX to provide DID/CO intercept treatment rather th an the
satellite PBX
Extended Trunk Access
Used with Uniform Dial Plan, allows DEFINITY ECS to send any unrecognized
number (such as an extension not administered locally) to another system for
analysis and routing. Such unrecognized numbers can be Facil ity Access
Codes, Trunk Access Codes, or extensions that are not in the Uniform Dial Plan
table. Non-Uniform Dial Plan numbers are administered on either the Fir st Digit
Table (on the Dial Plan Record form) or the Second Digit Table. They also are not
administered on the Extended Trunk Access Call Screening Table. Exten ded
Trunk Access helps you make full use of automatic routi ng and Uniform Dial Plan.
