Test Specifications
2 RX Ref Sensitivity Type Ib FER
2 RX Ref Sensitivity Type Ib FER
Description This specification sets the upper limit for residual type Ib FER (Frame
Erasures) on a full-rate speech traffic channel (TCH/FS). If this upper
limit is exceeded, an “F” (for fail) will be displayed next to the RX FE
for RES Ib measurement result.
Default value The default value for the GSM900 Upper Limit is 0.12 (%). The default
value for the DCS1800 Upper Limit is 0.12 (%). The default value for
the PCS1900 Upper Limit is 0.10 (%).
NOTE Parameter 22, (RX BER/FER results) sets the units for this
specification (percent, ppm, or count).
Example If you want your test procedure to report a failure if the number of
residual Type Ib frame erasures exceeds 200, you would enter 0 in the
lower-limit column and 200 in the upper-limit column. Next, set
parameter RX BER/FER Results to 0 to have results displayed in
frame erasure count.
