@@ -618,11 +618,11 @@ The one exception is a special radio block occasionally used on the Uplink
 consisting of a sequence of four Access Bursts (see 3GPP TS 44.060).  The
 transceiver shall use `0110` as the modulation type to indicate that.
 
-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).
