Call Test Parameters (GSM/DCS/PCS)
While the phone under test is in an active call, the pa-
rameters for each band should be verified as described.
¹Power Level = 5
²Set BS TCH level to -105 dBm
³Set BER TCH level to -105 dBm with 10k bits or 128 Frames
Table 4. GSM Call Parameters
Figure 16. Burst Output Shape
¹Power Level = 0
²Set BS TCH level to -103 dBm
³Set BER TCH level to -103 dBm with 10k bits or 128 Frames
Table 5. DCS Call Parameters
¹Power Level = 0
²Set BS TCH level to -104 dBm
³Set BER TCH level to -104 dBm with 10k bits or 128 Frames
Table 6. PCS Call Parameters
Burst Output Shape should fall within the standard lim-
its of the Power Ramp.
BER measurements is only required if RX Quality reads
a value of 4 or greater.
It is recommended that handover procedures be per-
formed as shown in the following table.
