Block Types and Descriptions
Maximum Sound And Silence
Continuous Noise The maximum continuous noise before assuming an error (measured in milliseconds). This value
is assigned during call progress training. It should not be changed without good reason.
Continuous Silence The maximum continuous silence before assuming an error (measured in milliseconds). This
value is assigned during call progress training. It should not be changed without good reason.
Delay Before Returning
After Loop Current Drop Delay after a loop current drop before detecting an answer (measured in milliseconds).
This value is assigned during call progress training. It should not be changed without good reason.
Answer Detection
Maximum Size Of "Hello" The maximum time to wait for called party to stop talking (measured in milliseconds).
"Hello" Filter Duration Minimum gap in speech to decide if called party has stopped talking (measured in millisec-
onds).
Leading Or Trailing Edge If set to (1), this reports to the system an answer at the beginning of 'hello' . If set to
(2), the system reports at the end of 'hello'.
Sound And Silence Filters
Sound Filter Duration Minimum gap in sound before assuming the end of silence (measured in milliseconds). This
value is assigned during call progress training. It should not be changed without good reason.
Silence Filter During Minimum gap of silence before assuming end of silence (measured in milliseconds). This
value is assigned during call progress training. It should not be changed without good reason.
Sound And Silence Tolerance
This sets acceptable signal parameters. Tolerance numbers are usually assigned by the CP Train routine found on
Page 1 of the Station Block. Whenever adding components or making changes to the system, run CP Train to check
values. In very complicated cases where the assigned values don't quite work, the installing technician may have to
adjust the numbers assigned by the Train routine. All of these values are assigned during call progress training. They
should not be changed without good reason.
Sound Tolerance Above Amount of sound that can vary upward without breaking cadence...(%).
Sound Tolerance Below Amount of sound that can vary downward without breaking cadence...(%).
Amount the first silence can vary upward from some accepted level without

1st Silence Tolerance Below: ... (%) Amount the first silence can vary downward from some accepted level with-
out breaking cadence.
