TRXD: further clarify meaning of Training / Synch. Sequence Code
Both Synch. sequence and Training sequence are basically the same thing,
only the length is different. I guess this is why 3GPP TS 45.002 names
them differently. Let's mention them both to avoid confusion.

-Training Sequence Code::
-The Training Sequence Code identifies the Training Sequence of a received
-burst. The value of this field corresponds to one of the sequences defined
-in 3GPP TS 45.002, section 5.2, and depends on the actual modulation and
-the TSC set indicated by the preceding bits.
+Training / Synch. Sequence Code::
+In combination with a modulation type and a TS set number, this field uniquely
+identifies the Training Sequence of a received Normal Burst (see tables 5.2.3a-d)
+or Synchronization Burst (see table 5.2.5-3), or the Synch. Sequence of a
+received Access Burst (see table 5.2.7-3 and 5.2.7-4).
