2.4 Radio exchange tests
2.4.1 Ringing detection test
The purpose of this test is to check whether the radio exchange can discriminate between the internal/
external and call back ringing cadences, as programmed during initialization. This test is only
necessary when LTUs are used in the system.
Test
1. Make an internal call from one cordless phone to another. The called cordless phone must ring
according to the internal ringing cadence.
2. Make an external call from one cordless phone to another. The called cordless phone must ring
according to the external ringing cadence.
3. Generate a call-back from one cordless phone to another. The called cordless phone must ring
according to the call-back ringing cadence.
2.4.2 Call transfer test
The purpose of this test is to check the selected R-button signalling.
Test
Make a call from cordless phone 1 to cordless phone 2. If cordless phone 2 can transfer the call to
cordless phone 3 the call transfer settings are approved.
2.4.3 General alarm test
This test is only necessary if an alarm device is connected to the general alarm relay on the Modular
Cabinet Connection Board (MCCB).
Test
1. Generate a general alarm by e.g. disconnecting a CLU signal cable or a CLU/MDF cable set from
a CLU, CLU-S or a SLU board. The alarm device connected to the general alarm relay must be
activated.
2.4.4 Battery power unit test
This test must be executed if a battery power unit is used. The purpose of this test is to verify that the
switching from an external supply to battery supply works properly.
Test
Remove the mains supply from the battery power unit by disconnecting the mains lead from the local
wall outlet. The DCT1800-GAP system must continue to function correctly.
