NOTES:
1 The reject procedures not required
2. The RR, RNR and REJECT procedures are a Iocf DTUDCE matter and the correspondrng packets are not forwarded to the XDCE.
3. Table entnes are defined as follows: A = achon to k taken, S = the state to Lx entered, D = the diagnostic code to be used 1n
packets generated as a result of this action, DISCARD tndicates that the received packet is to be cleared from the XDLP buffers,
and INVALID Indicates that the packetlstate combinat~on cannot occur.
4. The error procedure consists of perfomtng the specified act~onsw hen entering the d3 state (which ~ncludesF orwarding a RESET
REQUEST packet to the DTE) and sendtng a RESET REQUEST packet to the XDCE (via the reformatting process).
