The fields in the SiConnReq structure are encoded as follows:
Field |
Value |
locRef |
A 24-bit number used by the originating exchange as a reference for this connection. |
pntCde |
A 32-bit number of which the least significant 24 bits (ANSI) or the least significant 14 bits (ITU-T) are used. For example, an ANSI point code represented by the decimal string 1.4.7 is encoded as hexadecimal number 0x00010407. |
protClass |
SCCP protocol class (binary encoding) defined in the ANSI or ITU-T recommendations. |
credit |
Window size requested for end-to-end connection. |
