25 Questions

1. 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.

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

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

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

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

6. Are used to directly interconnect two signaling endpoints

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

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

9. The MTP3 protocol is divided into two main functions

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

11. Interconnect an STP with its mate.

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

13. Routes SS7 messages during normal conditions.

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

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

16. Is used to route the call through the network

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

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

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

20. Network provides the intelligence to the existing PSTN

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

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

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

24. 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.

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