11.1.8.2. Service Information 
- If the dialed station number leads to a station in the same system, the dialed station's ITR group is used for selecting the attendant console group to which the call is forwarded.
- If the dialed station number leads to a station in a remote system
within a CorNet-N private network, the ITR group depends on the ITRN
parameter value of the class-of-trunk (COT) of the calling line:
- If ITRN ist set, the dialled station's ITR group is used for selecting the attendant console group to which the call is forwarded.
- If ITRN ist not set, the calling line's ITR group is used for selecting the attendant console group to which the call is forwarded.
- If the dialled station number leads to a station in a non-networked remote system, the calling line's ITR group is always used for selecting the attendant console group to which the call is forwarded.
Hint:
Before an ATNDGR can be deleted, and unless it is the only one in
the system, another ATNDGR must be entered with the CHANGE VFGR action
as intercept destination. Assign an ATNDGR to an ITRGR as an intercept
destination (ITDEST), e,g. 5.
AD-VFGR:ATNDGR=number,{NOPT1...NTVA8},
OPT=number,CQMAXF=number,ITDEST=5;
