SS7 has several advantages compared with traditional signaling systems. Write Some obvious advantages of SS7 signaling?
Fill in the Gaps
A _______________________________ is a switching or, processing node in a signaling network, with the functions of SS7 implemented.
A signaling point, at which a message is received on one signaling link and then transferred to another link, without processing the contents of the message, is called a _____________________________.
All Signaling Points in a SS7 Signaling Network are identified by a unique code ______________ bits known as a ___________________________.
The common channel signaling system uses ____________________________ to convey the signaling messages between two signaling points.
The message is distributed to the appropriate user part (e.g., ISUP or SCCP) indicated by the ______________________________.
The selection of outgoing link is based on information in the DPC and __________________________.
