Always On / Dynamic ISDN AT Commands

AT!X25=n	Specify Number of Logical Connection Numbers. Note that the number of Logical
	Connection numbers affects the range ofAT!X21. SeeAT!X21.
	Range: 1-4.
	Default: 1.

AT!X26=n	Specify Type of User Data for X.25 Call Request Packet. Specifies the type of user
	data for X.25 call requests. Normally, the value of this parameter should be left to the
	default CF (PPP over X.25). If your switch doesn't recognize CF, you won't be able to
	connect; if this is the case you should set the value to nothing (AT!X26= ).
	Default: CF (PPP over X.25).
