TCH Timeslot Tests
1 In this test, the OMC operator unlocks individual TCH timeslots and the field technician
places a mobile-to-mobile call over each timeslot using a mobile handset in debug mode.
Refer to the documentation provided by the module handset manufacturer for the proper
procedures.
For each timeslot, the commissioner should verify that:
• The timeslot displayed on the handset corresponds to the timeslot unlocked by the
OMC operator.
• A two-way call is completed successfully.
• The call has good audio quality and power, and low interference.
The number of timeslots to be tested differs depending on whether you have one, two or
three TRXs. Table 5-1 provides the sequence for 1 TRX, Table 5-2 provides the sequence
for 2 or more TRXs.
