How are Check bits (CKs) used in SUs?
To determine if the SU was transferred without any errors.
What information does the Service Information Octet (SIO) in MSUs contain?
Service Indicator (SI) and Network Identifier (NI).
How many User Parts (UPs) can be defined using the Service Indicator (SI) bits in MSUs?
16
What does the Subservice field in the Service Information Octet indicate?

What action does the signalling traffic management take when a signalling link fails?
Initiate a changeover to a fault-free signalling link
In case of overloading, what does the signalling traffic management do?
Informs adjacent SPs of overloading and requests load reduction
What role do User Parts (UPs) play in the signalling system?
Accomplish functions like message formatting for specific user types
When a signalling link becomes available after a fault is corrected, what action does the signalling traffic management take?
Initiate a changeback to reverse the effect of the changeover
What does the signalling traffic management do when it can no longer reach Service Provider (SP) on a normal route?
Reroutes the signalling traffic to a predefined alternative route
How does the signalling traffic management achieve its functions?
Exchanging management messages with signalling route management
