Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. L1 - L2 - and L3 provide the transport protocols for all other SS7 protocols - includes network interface specifications - reliable transfer of information - and message handling and routing






2. Provides access to remote databases for routing information and enables features in remote network entities






3. __are end office or tandem switches that connect voice circuits and perform the necessary signaling functions to originate and terminate calls.






4. How may layers does the SS7 protocal stack have






5. Used to reroute or divert traffic and control congestion during network failure conditions.






6. Uses SCCP and MTP to route transaction messages in the SS7 network






7. Is a circuit-based protocol used to establish and maintain connections for voice and data calls.






8. Uses a separate logical path for signaling and voice.is the most common form of signaling in the SS7 network

12. Are used to interconnect mated STP pairs of one hierarchical level






13. __performs out-of-band signaling in the Public Switched Telephone Network (PSTN).






14. Interconnect an STP with its mate.






15. __handles call establishment - exchange of information - routing - operations - billing - and support for IN services






16. Supports physical circuit connections but is unable to handle the virtual connections and bearer circuits used in today's digital networks






17. Physical and electrical characteristics of the signaling link. T1 - DS-0 - E1 - V.35






18. Global title translation centralizes the selection of the correct database by enabling __ to be addressed directly to the STP.






19. Provides end-to-end addressing and routing for L4 protocols such as transaction capabilities application part (TCAP).






20. __sets up and tears down the circuits used to connect PSTN voice and data subscribers - connects - manages - and disconnects all voice and data calls in the PSTN.






21. All signaling elements are identified by a numerical __ __ - which acts as a routing address in SS7






22. Are used to directly interconnect two signaling endpoints






23. Signaling uses a separate logical path for signaling through the minimal number of transfer points to reach the final destination






24. The signaling and voice paths are directly connected between the two signaling endpoints.






25. SS7 occurs when the same transmission channel carries the bearer's information and the signaling information.






26. Used in cellular networks to store information such as current cellular phone location - billing - and cellular subscriber information.






27. Process handles the rerouting of traffic through alternate links or linksets during network link failures - also controls the flow of traffic to specific endpoints during network link failures.






28. Monitors and controls the individual links of the signaling endpoint.






29. Is used to complete the call at the terminating SSP






30. Provides subscriber or user information such as screening and barring - calling-card services including card validation and personal identification number (PIN) - authentication - and billing.






31. Protocol is used to create reliable point-to-point links between endpoints in a network - perform error detection - indicate link status - and transfer information messages.






32. Signaling links are grouped together into __when the links are connected to the same endpoint.
