If there is a problem and DLCIs 16 and 18 go inactive, the IQ 710 would not dial because all DLCIs in the
group are not inactive (DLCI 20 is still active). If DLCI 20 then goes inactive, all three DLCIs (16, 18, and
20) defined in the group are now inactive and the IQ 710 would dial. It will dial the Birmingham site first
since it is defined as call order one.
If at this point DLCI 16 becomes active, the IQ 710 would disconnect the call to the Birmingham site, since
all DLCIs in the group are not inactive.
