The routing table just holdes the information from which partner(s) a certain bulletin is allowed to be received and NOT from where it is actually received from.
Therefore some bulletins are included several times with different information for the "Receiving Centre". This is e.g. the case fpr the bulletin SABZ21 SBAR:

"SABZ21 SBAR","AFTN","LDZM","LTAA","AFTN","EDZW"
"SABZ21 SBAR","HABP","LDZM","LTAA","AFTN","EDZW"
"SABZ21 SBAR","LYBM","LDZM","LTAA","AFTN","EDZW"
"SABZ21 SBAR","EDZW","LDZM","LTAA","AFTN","EDZW"
"SABZ21 SBAR","LJLM","LDZM","LTAA","AFTN","EDZW"
"SABZ21 SBAR","OKPR","LDZM","LTAA","AFTN","EDZW"
"SABZ21 SBAR","LZIB","LDZM","LTAA","AFTN","EDZW"


The indication “XXXX” is used for all cases where a bulletin is sent only to an internal or national system but not to any international centre.


In the routing table there are a lot of wildcard routings like “FC//// ////”. This has to be interpreted in the way that every FC-bulletin that is 
not defined in more detail within the routing catalogue will be routed according to this definition.
 
For example if we would receive a “FCAA31 AAAA”  this would be routed based on the definition for "FC//// ////" as there is no routing table entry for "FCAA// ////" or
"FCAA31 ////" or even "FCAA31 AAAA".
