Operation Mode (opmode) : This field defines operation mode of ISDN PRI interfaces. You can
choose it between NET and USER mode. You should cooperate with PBX or PSTN central office
switches. For instance, VoIP gateway should configure it as NET mode if PBX is set up as USER mode.
If this mode does not fit properly, you cannot make calls although E1 line is connected and the
status is normal.
Dialing Mode in O/G Call SETUP (dmode) : Dialing mode defines the method to send dialed digits
You can choose it between overlap and enbloc.
Dial tone send in seizure (dsend) : When a channel is seizured in PRI line, this field selects whether
GW plays a dial tone to collect digits or not.
Ringback tone send in alert (rsend) : After receiving alerting message, this field defines whether GW
plays ringback tone or not. You need to check PBX configuration because there are also dial and
ringback tone options in PBX.

value is 3 seconds. Thus, next digit should come within 3 seconds in order to send a call properly.
wait last INFO timer (lit) : This field defines a waiting time after dialing.
L2 re-establish after L1 recoverd (l2rest) : If a LAPD connection in ISDN PRI is lost for various kinds
of reasons, GW will constantly re-establish LAPD connection after L1 recovered when this field is
enabled.
