6.6.1 SS7_MSG_RESET – Q.SAAL Module Reset Request
Synopsis:
Message used to initialize the Q.SAAL module for operation, in the same way as MTP2.
Message Format:
Description
First message sent to the Q.SAAL module to initialise all the per module options.
Note: This message is to be sent once for each board by the SSDM module, with the message Instance
identifying the board ID.
Until this message has been received and returned with a zero status field, all other messages (except
GEN_MSG_MOD_IDENT) will be returned with a non-zero status field.
GEN_MSG_MOD_IDENT messages will be processed in an identical fashion both before and after the
processing of this message.
Once a SS7_MSG_RESET message has been correctly processed for a board, subsequent SS7_MSG_RESET
message for the same board will be rejected with a non zero status field.
