【正文】 s display is used to toggle BTS_TEST status on EEPROM. If BTS_TEST status is set on EEPROM each time the mobile sends a search list it uses only the carrier number stored on SIM SCMlocation 33. Also the neighbour information from system information messages is ignored. If the BTS_TEST status is not set, then the value of SIM SCMlocation 33 is ignored and the mobile behaves normally (. does the neighbour measurements according the GSM specifications). To activate BTS tests perform following steps: Save desired channel number in SIM SCMlocation 33. Select display 17 in execute mode Switch power off and on If activation succeeded, there is text BTS TEST ON in display 17. To deactivate BTS tests either select display 17 in execute mode or save number 0 in SIM SCMlocation 33 and switch power off and on. NOTE! The display does not show the value of BTS_TEST status in EEPROM. Although the value is set, bts test can be off. If there is not legal carrier number in SIM location 33 (GSM: 1124, DCS1800: 512885) the display shows that bts test is off. Also if the mobile was already registered to some carrier before switching BTS_TEST status, the display can show different value from the one in EEPROM. See chapter for remendations.

By setting the barring on in the base station normal GSM phones will not try to register these barred cells. By selecting cell barring reversed, the MS will only use the cells to be tested. However, if at the same time it is wanted that MS will be capable to use normal network cell barring ignored can be set. Display 19 will show the cell barring mode. NOTE! If a cell has been selected before barring state is changed the selected cell may have different barring state than what the display shows. After reselection the cell barring state is working for sure.
