IV. Testing Mode 4.1 Idle Mode In idle mode, the mobile station is standby and not making any call. You can just click record button to start recording idle mode. Use Idle Mode to test sectorization and cross feeder on the night of cut over. 4.2 Idle Lock and Idle Prevent When the mobile station is in idle mode, it can be locked to one channel or to a set of channels. This inhibits all reselections to other channels, regardless of the signal strength and quality of neighboring cells. The inverted operation is also possible, namely to prevent reselection to a specified channel set. Click
on the toolbar, and select which channel you want to lock
To reset the lock on channel function, simply click

4.4 Force Handover and Prevent Handover When the mobile station is in dedicated mode, you can manipulate handovers. Specifically, you can do one of the following: Prevent handover to specified channels. The mobile then reports no signal strength for these channels. Force handover to a specified channel, or restrict handovers to a chosen channel set. The mobile then reports a RxLev of 63 for any such cell, 10 for the serving cell and no RxLev for other neighboring cells. Click
(Equipment Properties) on the toolbar
