DEFINITY Switch Data Collection
Issue 4 September 1995
H-11
If VRU data is returned, the calling party is able to touch-tone a response to a
DEFINITY prompt only after the data collection phase is completed and another
collect digits
step is executed. This is true because each executed
collect digits
step does not allocate a TTR when dial-ahead digits are present. Since VRU-
returned digits are treated as dial-ahead digits, a TTR is attached to the call only
after all returned digits are collected and another
collect digits
step is
encountered. Only at this point can the caller hear an announcement for the
collect digits
command and successfully enter digits.
