Call Waiting Deluxe in Conjunction with the Analog Display Services Interface (ADSI) Update 1/23/03

Original Disclosure Date: April 1, 1994 Update to Network Disclosure News #357
This disclosure announcement provides an update to the deployment information contained on the Attachment. This document completely replaces Network Disclosure News #357. The following is reiterated for your information. Interface specifications have not changed.
Summary:	QWEST offers CLASS Feature Call Waiting Deluxe (CWD) interface in conjunction with the Analog Display Services Interface (ADSI). Call Waiting Deluxe allows a customer to control the treatment applied to incoming calls while the customer is off hook on a stable call via a visual display presented by the CPE. CWD is compatible with Type 3 CPE. ADSI protocol provides bi-directional data communications between an SPCS (Stored Program Control Switch) or ADSI Server and ADSI compatible CPE.
Locations and Timing of Deployment: *	Locations where Call Waiting Deluxe is planned or currently available can be found in Attachment 1. If the interface changes in the future, QWEST will issue a new Network Disclosure. In addition, any new deployment locations will be added to the QWEST web site at http://www.uswest.com/disclosures in disclosure #406. Call Waiting Deluxe deployment to the following new switch location in the sate of Iowa: Waukee (WAUKIACODS1).
Pricing:	This interface is available under tariff.
Interface Requirements:	Telcordia Technical Reference GR-416-CORE, Call Waiting Deluxe, FDS (Feature Document Specifications) 01-02-1215, Issue 2, December 1999. Telcordia Technical Reference GR-30-CORE and GR-1273-CORE, define the actual data transmission interface requirements and address the physical, data link and message layers. GR-30-CORE, Voiceband Data Transmission Interface Generic Requirements, Issue 1, December 1994, defines requirements for data transmission in both the on-hook and off-hook states. On-hook data transmission associated with power ringing is currently being used by QWEST to transmit Caller Identification information from the serving central office switch to the CPE and will not change. Off-hook data transmission will be used to transmit Caller Identification information during a Call Waiting state. In the off-hook state, the actual data transmission will be preceded by an inband CPE Alerting Signal (CAS), defined as an 80-85 ms dual tone, with nominal frequencies of 2130 Hz and 2750 Hz. The data transmission rate will be 1200 baud, with a continuous-phase binary frequency shift keying (BFSK) modulation. GR-1273-CORE, Generic Requirements for an SPCS to Customer Premises Equipment Data Interface for Analog Display Services, Issue 1, July 1998, defines the Analog Display Services Interface (ADSI). The ADSI protocol provides bi-directional data communications between an SPCS (switch) or Server (host computer) and ADSI-Compatible CPE allowing a customer to use screen based information and call management features via their CPE. The standard Analog Display protocol uses both DTMF and GR-30 CAS tones, and GR-30-CORE physical layer protocol type modem signaling to provide basic communication between the SPCS/Server and the CPE. The SPCS/Server will use a voice band CAS to "wake up" the CPE to receive data, as in the off-hook GR-30 protocol. The CPE will use various combinations of DTMF tones to provide acknowledgments and responses to the SPCS/Server. The following Telcordia Special Reports, SR-TSV-002476 and SR-2461 provide compatibility guidelines for CPE to operate with the data interfaces defined. SR-TSV-002578 describes a method for detecting a dual tone signal in the presence of speech. These SRs may be helpful to vendors who plan to build ADSI compatible CPE.

Bulletins: December 1993 Revision 1: June 1995 SR-2461, Customer Premises Equipment Compatibility Guidelines for the Analog Display Services Interface, Issue 1, July 1998.
