The error procedure consists of performing the specified actions when entering the d3 state (which includes forwarding a RESET REQUEST packet to the DTE) and sending a RESET REQUEST packet to the XDCE (via the reformatting process). 2007/70/II. szám Annex 10 — Aeronautical Telecommunications Volume III 5-40 28/11/02 No. 77 Table 5-9.

XDCE actions at state transition XDCE state State definition Action that shall be taken when entering the state r1 PACKET LEVEL READY Return all SVCs to the p1 state. p1 READY Release all resources assigned to the SVC. Break the correspondence between the ADCE/GDCE SVC and the DTE/DCE SVC (the DTE/DCE SVC may not yet be in a p1 state). p2 GDLP(ADLP) CALL REQUEST Determine if sufficient resources exist to support request; if so allocate resources and forward Mode S CALL REQUEST packet to reformatting process; if not, enter ADCE(GDCE) CLEAR REQUEST to GDLP(ADLP) state (p7). p3 ADCE(GDCE) CALL REQUEST Determine if sufficient resources exist to support request; if so, allocate resources and forward Mode S CALL REQUEST packet to frame processing; if not, send Mode S CLEAR REQUEST to reformatting process and go to state p1. Do not forward the Mode S CALL REQUEST to the peer XDCE. p4 DATA TRANSFER No action. p6 GDLP(ADLP) CLEAR REQUEST Release all resources, send a Mode S CLEAR CONFIRMATlON packet to the peer XDCE and enter the p1 state. p7 ADCE(GDCE) CLEAR REQUEST to GDLP(ADLP) Forward Mode S CLEAR REQUEST packet to the peer XDCE via frame processing. d1 FLOW CONTROL READY No action. d2 GDLP(ADLP) RESET REQUEST Remove Mode S DATA packets transmitted to peer XDCE from window; discard any DATA packets that represent partially transmitted M-bit sequences and discard any Mode S INTERRUPT packets awaiting transfer to the peer XDCE; reset all flow control window counters to 0 (5.2.6.7.1).
