Set V.18 Annex A signal duration threshold for tone detection.

V.18 threshold commands are used to specify minimum detectable signal values, and are 
especially geared toward improving telecommunications for the hearing or speech-impaired; 
for example, various thresholds are available to control duration (hang time) and strength 
(level) or even incremental (fractional) signaling.

Definitions:
slot

Specifies chassis slot number where VSM is installed, (e.g., 

).

Specifies physical port number on voice daughtercard, (e.g., 

).

).

The last number in the range of voice channels (e.g., 

). 

♦ Syntax Note ♦

Be sure to separate the start and end range numbers with a 

hyphen (e.g., 

).

Specifies the signal duration threshold for V.18 tone detection, in milliseconds from 5 to 
32767, (e.g., 

).

♦ Syntax Note ♦

Do not use commas when entering the V.18 tone detection 
threshold hang time value (for example, 

 will return a 

syntax error message).

Default:
The default value is 

 milliseconds.
