If a TTY caller calls the number that connects to vector 33, the following occurs:
1
After a short burst of ringing, a quick burst of TTY tones is sent to the caller telling the caller to
hold, "HD". Then, a voice announcement follows for callers using a normal telephone
connection. The announcement tells them to stay on the line. Finally, another burst of TTY tones
is sent to the TTY caller which displays on the caller's TTY device as, "Dial 1."
The TTY caller won't hear the voice announcement, but because the step collects digits, it allows
the caller to enter 1 on his or her touchtone phone.
NOTE:
For voice callers, the burst of TTY tones lasts about one second and sounds like a bird
chirping.
2
In vector step 3, since the TTY caller entered 1 in vector step 2, the TTY caller is sent to vector
step 8, at which point the caller is put in queue for a TTY-enabled agent in split 47.
NOTE:
The voice caller is sent to vector step 3 also, but a voice caller does not go to vector step 8
because the caller did not enter 1 at vector step 2. Instead, voice callers continue on to
vector step 4, where they connect to split 48.
3
While the TTY caller waits in queue, he or she hears silence from vector step 9, then the
announcement in vector step 10, and is then looped back to wait with silence by vector step 11.

Fixing vector problems
If there is a problem with a vector, Communication Manager records the error as a vector event. Vector
events occur for a number of reasons including problems with a trunk, full queue slots, or the vector
reaching the maximum 1000 steps allowed.
