Event specific parameters

 

 

 

Description:

This primitive is used by MTP2 to advise management of the occurrence of protocol related events in accordance with Q.752. These events either relate to the reason for a signaling link (that was in service) going out of service (events prefixed S7F_) or the occurrence of congestion related events (prefixed S7G_).

Parameter Description:

Event Code

The Event Code coding and the meaning of the event specific parameters are given in the following table:

•link is indicated as (linkset_id * 256) + link_ref, (size = 2).

•linkset is indicated as linkset_id, (size = 1).

•point code is a 4 byte value, (size = 4).
