Note: Miscellaneous switching termination entities always are identified by the
alpha character "D" in character position 11 of the CLLI code format.
Upper case characters displayed in the code format are the required characters
for that type of entity.
Entity types "Other (miscellaneous) Switching Termination Entities" and
"TSPS Common Control Unit" will accept any alpha or numeric character in
position 9. The remaining entity types on this list require any numeric
character, 0 through 9, in position 9.
* When identifying announcement systems, the announcement machine portion of
the system should be coded (n)AD. The distributors should be coded (n)DD, except
for Time and Weather Distributors which are coded (n)TD and (n)WD, respectively.
# Formerly called Miscellaneous Traffic Unit Terminations.
