#
# t_resel_utra: Cell reselection timer (seconds)
# t_resel_utra_sf: Optional speed dependent ScalingFactor for t_resel_utra.
# sf_medium: Scaling factor if the UE is in Medium Mobility state, one of "0.25", "0.5", "0.75" or "1.0".
# sf_high: Scaling factor if the UE is in High Mobility state, one of "0.25", "0.5", "0.75" or "1.0".
# carrier_freq_list_utra_fdd / carrier_freq_list_utra_tdd: A list of carrier frequencies of UTRA FDD / TDD.
# carrier_freq: The UARFCN for the UTRA carrier frequency.
# cell_resel_prio: Optional absolute priority of the carrier frequency group.
# thresh_x_high: Srclev threshold (dB) to select to a higher-priority RAT/Frequency.
# thresh_x_low: Srclev threshold (dB) to select to a lower-priority RAT/Frequency.
# q_rx_lev_min: Minimum receive level in UTRA cell, ([field_val] * 2) + 1 = [level in dBm].
# p_max_utra: The maximum allowed transmission power on the (uplink) carrier frequency.
# q_qual_min: Minimum required quality leve in UTRA cell, applicable only for FDD cells.
