↲
╞ *1) ┆84┆This stands for the following algorithme: Using the user inf ↓
┆19┆┆8d┆┄┄field in the packet description, a lookup is performed in the ↓
┆19┆┆8d┆┄┄submit_error_table described in section 8.3. This will deliver ↓
┆19┆┆8d┆┄┄two values a retries count and a retry timer. ↲
↲
╞ ┆84┆The following is done:↲
↲
╞ ┆84┆If user inf=error inf (the same error two times in a row), ↓
┆19┆┆8d┆┄┄retries left will be decreased with one. Otherwise is retries ↓
┆19┆┆8d┆┄┄left set to retries count.↲
↲
╞ ┆84┆After that is error inf set to user inf, and retry timer is ↓
┆19┆┆8d┆┄┄added to retry timer sum.↲
↲
╞ ┆84┆The following possibilities then arises:↲
↲
a) ┆84┆retries left =0↲
╞ The pseudo event giveup is performed.↲
↲
╞ b) ┆84┆retry timer sum>= max retry timer (see section 8.3)↲
╞ ┆84┆giveup is performed.↲
↲
╞ c) ┆84┆Otherwise the pseudo event encapsulation is performed.↲
↲
┆8c┆┆83┆┆e4┆↓
╞ ┆84┆The following should be noted, however:↲
↲
╞ (a) ┆84┆If user inf indicates prio break, a retry timer=0 is used ↓
┆19┆┆91┆┄┄giving an immediate retry (which probably will cause the ↓
┆19┆┆91┆┄┄packet to enter the busy queue).↲
↲
╞ (b) ┆84┆If the error was a SESS START CONF NEG with rej_reason= ↓
┆19┆┆91┆┄┄address_enc, the retry timer is given in the SESS START ↓
┆19┆┆91┆┄┄CONF NEG. (The wait_time parameter).↲
↲
╞ (c) ┆84┆If the error was a answ SESS START REQ with result=busy, ↓
┆19┆┆91┆┄┄the retry timer value from submit_error_table is not used, ↓
┆19┆┆91┆┄┄but a short timer value, busy_retry_timer (see section ↓
┆19┆┆91┆┄┄8.3).↲
↲
╞ ┆84┆the reason for this is that the session resources should ↓
┆19┆┆91┆┄┄be configurated alike in DH and S62CP. A busy answer must ↓
┆19┆┆91┆┄┄therefore be due to the following situation.↲

↲

┆19┆┆89┆┄┄packet where a TU removed event has occurred while a document ↓
┆19┆┆89┆┄┄stream has been open or not fully terminated.↲
↲
╞ ┆84┆All packet communication with DS is terminated, but the packet is ↓
┆19┆┆89┆┄┄not disconnected from the session before the stream has been ↓
┆19┆┆89┆┄┄terminated. This ensures that the session and thereby the TU, is ↓
┆19┆┆89┆┄┄alive until this happens.↲
↲
╞ ┆84┆The following entry points can be entered both from packet source ↓
┆19┆┆89┆┄┄states (section 6.4) or packet sink states (section 6.5). The ↓
┆19┆┆89┆┄┄events to the protocol machine are the S62CP events that can occur ↓
┆19┆┆89┆┄┄for these states, but most of them are ignored (they are crossing ↓
┆19┆┆89┆┄┄the SESS ABORT REQ at the interface).↲
