Can you answer question 4?

1. What is the function of an STP? Differentiate between an STP and a signaling point
(SSP).
2. Layer 2 of the SS7 protocol functions as the signaling link. In one sentence, describe
what layer 2 does. Name some of the functions of this layer.
3. What are the two basic categories of functions of layer 3 of SS7? What is the basic
purpose of layer 3?
4. Inter-relate message routing, message discrimination and message distribution.
5. What does a routing label in SS7 do/provide?
6. What is the basic method of error detection in SS7?
7. There are 3 types of signal units used in SS7. What are they and describe the basic
function of each.
8. Differentiate forward and backward sequence numbers. In essence, what do FSN and
BSN accomplish?
9. What are the 3 basic measures of performance in SS7 (not in the notes-think about the
way SS7 and in general most network operate)?
10. Regarding user parts, what is the function of the SIO?
