<h1><a id="frame-format" name="frame-format">3. Frame Format</a></h1>
<p>TinyOS has two 802.15.4 frame formats. The first format, the T-Frame, is
for TinyOS networks which do not share their channel with other wireless
-networking archtiectures. This frame format assumes that TinyOS can use
+networking architectures. This frame format assumes that TinyOS can use
every bit of the packet and does not need to state that it is a TinyOS packet.
T-Frame stands for "TinyOS Frame."</p>
<p>The TinyOS 802.15.4 T-frame format is as follows:</p>
| 802.15.4 Header | 6lowpan | AM type | data | 802.15.4 CRC |
+-------------------+---------+------------------------------+--------------+
</pre>
-<p>AM type is the same as in a T-frame. 6lowpan is the IANA-assigned code
-to identify this as a TinyOS packet. At this time, the exact value of
-this code has not been determined. To inform 6lowpan that this is not
-a 6lowpan packet, the code used MUST be in the range of 192-55.</p>
-<p>The AM type 6lowpan is reserved. A TinyOS program MUST NOT use it.</p>
+<p>AM type is the same as in a T-frame. 6lowpan is the NALP code to identify
+this as a TinyOS packet. NALP codes must be in the range of 0-63.
+TinyOS uses code 63.</p>
+<p>The AM type 63 is reserved for both T-Frames and I-Frames. A TinyOS
+program MUST NOT use it.</p>
