"MUST only" seems a bit strong. I don't see why one should have to
reject a Sonet connection that had a Switching Type of TDM.
Perhaps "only MUST" was the intent.
I think the actual wording should be something to the effect,
When the switching type is implied traffic-parameters the Switching
Type field is ignored. The Switching Type field SHOULD be set to
either the implied value or to UNKNOWN. When the switching type is
not implied by the traffic-parameters it MUST be set to one of the
values [pointer to appropriate list] other than the value UNKNOWN.
The definition of the traffic parameters of Sonet should also carry a
note that the ST of TDM is implied.
