SYS_7: Hook Flash and Tone Detection
Hook Flash Length
SYS_7_1_[XXX]
XXX: the time length of a hook-flash
000~765= 0.00 ~ 7.65 seconds
If the Hook Flash length that the PBX requires is less than 0.13 seconds, or if the PBX does not
send out any tone after receiving a hook-flash of signaling to put a call on hold, you must
directly set the Hook-Flash length. For example: the required Hook Flash length is between 0.05
and 0.1 seconds, this setting should be 007 (0.07 seconds).

SYS_7_3_[XXX]
XXX: the time length that the EVM waits in order to delay initiating the tone detection to the
call after dialing a phone number
000~765= 0.00 ~ 7.65 seconds (Default= 003)

If you delete the existing values after the Automatic System Configuration mode is shut off, the
built-in parameter will be in place of this parameter.
