Main SP Tables-5
Connection Timing
Adjustment Incoming
When the Call Center calls out to an embedded RCG-M modem, it sends a
repeating ID tone (*#1#). This SP sets the time the line remains open to send
162
these ID tones after the number of the embedded RCG-M modem is dialed up
and connected.
The actual amount of time is this setting x 2 sec. For example, if you set "2"
the line will remain open for 4 sec.
