CHAPTER 5

Synchronization Test

5.1General

This test checks if two DCT1900 systems, whose coverage areas partly overlap and are connected to the same synchronization network, are correctly synchronized. The test is performed by setting up a call and moving from the coverage area of one DCT1900 system to the other.

5.2Test

1.Check if both DCT1900 systems report "system synchronization available" by observing the system screen of the CSMW Software (menu: System Manager-Control-System). If a system is not synchronized you can force synchronization by a system reset (ongoing calls are dropped), assuming that the synchronization network is set–up correctly.

2.Ensure that the Portable Telephone is correctly initialized and that both DCT1900 systems are in the same system range using the configuration tool.

3.Switch off the Portable Telephone and move to the coverage area of one of the DCT1900 systems.

4.Switch on the Portable Telephone and observe if the Portable Telephone registers itself to the system.

5.Make a call to a fixed or stationary telephone.

6.Monitor the speech quality while moving to the coverage area of the other DCT1900 system. If the call is not dropped and the speech quality remains good (no crackling sounds or mutes), then both systems are correctly synchronized.

7.You can verify the result by moving back again while making a call.
