Adjunct Switch Application Interface (ASAI)

Both CED and CDPD can be passed to an ASAI adjunct as collected digits with the adjunct routing link command and other event reports. ASAI passes a maximum of 16 digits.

If a TouchTone Receiver (TTR) is connected to a call as a result of ASAI-requested digit collection and the call encounters a collect ced or cdpd step, the TTR is disconnected from the call. In addition, any ASAI-requested digits stored in the collected digit buffer are discarded and no entered digits event report is sent.

ASAI does not distinguish between CINFO digits and user-entered digits that are collected as a result of a collect digits step. CINFO digits are provided to an ASAI adjunct in the same manner as any other collected digits from a vector.

The call offered to VDN domain event report contains the digits from the most recent collect ced or collect cdpd vector step.

Best Service Routing (BSR)

BSR digits are included with the call if a multisite BSR application routes the call to another Communication Manager.

Call Management System (CMS)

You do not have to enable the Vectoring (CINFO) field on the System-Parameters Customer-Options screen for ced or cdpd to be passed to CMS. Any version of the CMS accepts ced or cdpd.

Conference

When a conference is established, CINFO digits are merged into the call record of the conference. However, there is no indication of the party to which the digits were originally associated. For security reasons, the CINFO digits are erased when the first ISDN call drops out of the conference.

Look-Ahead Interflow (LAI)

CINFO digits are included with the call if LAI routes the call to another Communication Manager.

Transfer

If a call is transferred from Communication Manager, CINFO digits are lost. If a call is transferred to an internal extension, CINFO digits are retained.
