Notes:
5. Trunk supervision may be a digital implementation (DMI-MOS) of the default type or any of the available "OPTIONAL" types.
6. For 5ESS CO connections, the trunk class should be PFLASH. The direction, supervision, and signaling should be optioned as
indicated. Addressing should match on an IN and OUT basis. That is to say, incoming addressing on one end should match
outgoing on the other end and vice-versa. The CO trunk group should be administered so as to provide Cut-Through Mode of
Operation.
7. Trunk class may be either PF or PFLASH.
8. Trunk class should be PFLASH.
