Appeal No. 1999-1612
Application 08/614,188
paragraph; page 11, section 3.8, first and second paragraphs;
and page 14, section 3.10, first and second paragraphs, still
exist in the 1988 version. However, these sections state
unequivocally that “transmission of CND data from the
terminating SPCS to the CPE should never take place while the
CND customer is in an off-hook state [italics original].” We 6
find the 1988 version of TR-TSY-000031 evidence that the
problems noted in the 1986 version of that document had not
yet been solved.
In sum, we find the documents as a whole provide a view
of features Bellcore desired to be a part of a Call Waiting
service. However, these documents also detail a problem
associated with implementing the particular feature of
transmitting caller identification data to the busy line of
called party and make clear that a solution to the problem had
not been found. These documents then constitute little more
than an invitation to try and find a solution to the problem.
6SPCS is an acronym for Stored Program Control System.
Both the originating, or caller, and the terminating, or
called party, Customer Premise Equipment (CPE) each have SPCS
associated therewith.
