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

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

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

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

5. __routes all the signaling messages in the SS7 network

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

7. 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.

8. The interface between the SCP and the database system is accomplished by a standard protocol - which is typically

9. Exchanges routing information and status between signaling endpoints.

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

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

12. Interconnects between signaling endpoints and STPs

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

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

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

16. Are used to directly interconnect two signaling endpoints

17. Routing tables to provide alternate routes when the current route is unavailable.

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

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

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

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

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

24. Have statically predefined routes for destination endpoints - The route is made up of linksets; linksets can be part of more than one route

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

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

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

28. Is used to route the call through the network

29. How may layers does the SS7 protocal stack have

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

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

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

33. Provides the 10-digit LRN of the switch that serves the dialed-party number

34. What is the SS7 network architecture built for

35. 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.

36. 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

37. Interconnects between two mated pairs of STPs

38. The MTP3 protocol is divided into two main functions

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

44. 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

45. Routes SS7 messages during normal conditions.

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