How Converged Desktop Services works 15

In Converged Mode, both the CS 1000 telephone and the MCS 5100 PC

Client are integrated to provide both feature sets. In Converged Mode, the

CS 1000 telephone effectively becomes the audio device for the MCS 5100

PC Client, so that any audio requirement from the MCS 5100 user (for

example, Click-to-Call) is directed to the CS 1000 telephone.

A user may selectively deactivate ConvergedMode, so both the MCS 5100

client and the CS 1000 telephone become stand-alone devices. This allows

remote users to utilize the MCS 5100 client for both multimedia and voice

functionality (for example, using a USB headset with the MCS 5100 PC

Client). The voice functionality on a MCS 5100 client in Unconverged Mode

is limited to the voice features supported on the MCS 5100. The CS 1000

telephone maintains its full feature set as programmed.

The Converged Desktop featureutilizes the CDS software on the Signaling

Server and the SIP TrunkingApplication to integrate the two systems.

These functions became available in CS 1000 Release 4.0.

CDS is enabled between CS 1000 and MCS 5100 using several

components, including:

•SIP TrunkingApplication — SIP Gateway and Virtual Trunk Route

•CDS on the Signaling Server

•Application Module Link (AML) and Value Added Server (VAS)assigned

to the CDS application over the common ELAN subnet

•Control Directory Number (CDN) (Converged Services Directory

Number [CSDN]) to trigger messaging over the AML/VASlink associated

with CDS

•Automatic Call Distribution (ACD) queue with agents — used for the

PersonalCall Assistant (PCA) application associated with CDS

•telephone Class of Service — used to enable Converged Desktop

messaging

•telephone option for CSDN — redirects inbound calls directed to the

telephone to CSDN to enable Converged Desktop signaling

•optional Recorded Announcement (RAN) route — used to play progress

or delay indication to caller while waiting for PCA agent

•Converged Desktop as a part of the Service Package for the MCS

Client user

•dialing plan for CS 1000 and MCS 5100

In general, when a CS 1000 user is designated as a Converged Desktop

user, theyreceive a CS 1000 telephone and an MCS 5100 PC Client. The

telephone is programmed with a Class of Service to allow CDS messaging

(the options described in "CDS conﬁguration: overview" (page 47)).
