+ Packets received on <code class="Dv">downstream</code> must have 0x03
+ (indicating unnumbered information) as their first byte; if not the packet
+ is dropped. This byte is then stripped and the remainder of the packet sent
+ out on <code class="Dv">upstream</code>.</p>
+<p class="Pp">Conversely, packets received on <code class="Dv">upstream</code>
