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. Routes SS7 messages during normal conditions.






2. Are used to directly interconnect two signaling endpoints






3. 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

5. Exchanges routing information and status between signaling endpoints.






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






7. Interconnects between two mated pairs of STPs






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






9. The MTP3 protocol is divided into two main functions






10. Is used to route the call through the network






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






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






13. Used in cellular networks to store information on subscribers roaming outside the home network.






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






15. Protocol conversion from national versions to the ITU standard - Network-to-network interconnection points - Network security features such as screening - which is used to examine all incoming and outgoing messages to ensure authorization






16. TCAP typically uses ___ services to access databases in the SS7 network.






17. 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.






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






19. Provides the routing information for special numbers - such as 800 - 877 - 888 - 900 - and 976 numbers.






20. __routes all the signaling messages in the SS7 network






21. The key element for delivering IN applications on the telephony network






22. How may layers does the SS7 protocal stack have






23. Are used to interconnect an SSP to an alternate STP






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






25. Provides the transaction capabilities carried out by non-circuit based messages used to access remote databases and invoke remote feature capabilities in network elements.






26. Provides access to databases for additional routing information used in call processing. (who the call goes to)






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






28. 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.






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






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






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






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






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






34. Interconnect an STP with its mate.






35. Provide international connectivity where the same International Telecommunication Union (ITU) standards are deployed in both networks.






36. For SS7 the signaling planes and the voice circuit planes are __separated.






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






38. Interconnects between signaling endpoints and STPs






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






40. __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.






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






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