Trunk signaling arrangements
Trunk-to-trunk connections are further controlled by the signaling and
supervision arrangements assigned to each trunk.
Table 3 "Trunk signaling
arrangements" (page 161) summarizes the trunk signaling arrangements.

Two outgoing trunks cannot be connected unless a supervising party, local
to the system, is conferenced in the call. This is true regardless of the
supervisions.
Transfer from a supervised trunk to a non-supervised loop start trunk is
not permitted.
Operating parameters
If a conflict exists between the Class of Service (CLS) and Trunk
Group Access Restrictions (TGAR), the access denied restriction takes
precedence.
