AT&T 555-230-520 manual Data Passing, Definity

Data Passing

Any attempt to remove a hunt group, split or skill administered within a converse- on vector step is denied until the vector has been changed. Also, any attempt to make a hunt group, split, or skill nonvector-controlled is denied if the hunt group, split, or skill is called by a converse-onstep.

Data Passing

NOTE:

This phase is optional and is in effect only if the application calls for

DEFINITY to pass information in-band to the VRU.

The converse-onstep may outpulse up to two groups of digits to the VRU. Two sets of digits are available for outpulsing. The digits can serve two major purposes, as follows:

■Notify the VRU of the application to be executed

■Share call-related data, such as ANI (BN) or caller digits collected by

DEFINITY

In many applications both application selection and data sharing are required.

Since in many cases the digit strings are of variable length, DEFINITY always appends a pound sign (#) to the end of each digit string. Prompt and collect steps in the VRU script must therefore always be administered to expect the pound sign (#) as the end-of-string symbol and to include the pound sign in the digit count.

Sending the pound sign (#) prevents excessive delays and other problems caused by digit timeouts.

The complete outpulse sequence is summarized as follows:

1.VRU answers the call

2.Delay for the time administered in the ‘‘Converse first data delay’’ field in the System Parameters-Features form occurs

3.< data_1> is outpulsed

4.‘‘#’’ is outpulsed

5.Delay for the time administered in the ‘‘Converse second data delay’’ field in the System Parameters-Features form occurs

6.< data_2> is outpulsed

7.‘‘#’’ is outpulsed
